It can be done in various ways. But if the gadget does not have a SIM card slot, and there is a need to use the Internet in places where there is no wireless network, then the only option is to connect a 3g modem. Made in the form of a flash drive, it will help you catch the network wherever there is coverage cellular network... Here's how to connect your modem to your tablet and avoid potential problems.
When buying a modem, it is important to decide on the operator cellular so that it has coverage where the device will be used. Today the main choice is Megafon, MTS, Beeline, Tele2 and Yota. Which option to choose is everyone's personal business. But it is worth noting that Megafon and MTS are better suited for traveling throughout the country, since they have the largest coverage and are usually caught even in the outback. Tele2 is a fairly budget option, but at the same time there are a lot of places where the connection will not be caught, or the signal will be too weak. Beeline is an option for an amateur, there are good tariffs here, but far from the most favorable ones. Yota will appeal to those who like to fully manage their services. The operator is relatively young, so not all users trust him.
A device from one manufacturer does not work with SIM cards from another service provider... It is possible to change the accessory's firmware so that it works with any SIM, but this is quite problematic and unsafe from the point of view of the further operability of the modem.
Advice! The modem is usually sold with a SIM card and a connected tariff, so when buying, you should clarify which tariff is connected, and if necessary, switch to a more optimal one.
With regard to the device, the options may be as follows: model With distribution of Wi-Fi, 3G or 4G. The first type is the most convenient, since it does not require a physical connection to the device, and the whole setup is only to enable Wi-Fi. 3G modems are rare today, but they can be obtained from acquaintances or simply lie idle on the shelf. The downside is that the connection speed will not be the highest, but if the buyer is only interested in surfing or working with mail, then this option is quite suitable. 4G modems provide high-speed connection, which is enough for a variety of tasks - from just chatting on the network to online games.
Modem connection
It is not difficult to connect the device to the Internet using a USB modem. If the device is new, then there will be no problems at all, since they provide support for such devices, and usually there are no problems with installing the drivers. If the tablet is old, then nuances may arise, for example, the Prestigio and Lenovo models with a release date more than 5 years ago did not have OTG support, that is, they did not know how to work with USB devices even through the appropriate adapter.
You can connect a 3G modem to an Android tablet directly via the USB connector, if provided in the device, or via an OTG cable. When choosing the latter, you should first find out which output is provided in the tablet. So old Samsung models had not the usual microUSB output, but their own format with a wide plug. In modern models, a new Type-C format.
OTG cable
When the adapter is purchased, you need to connect usb modem to your Android tablet via this cable. The system should identify the device. In some cases, you will be automatically prompted to install drivers on the device, you must agree with this. After installing them, the Internet will automatically start working.
Advice! If the driver is not installed automatically, then it can be downloaded from the official website of the cellular operator or downloaded from Play Market... The instructions for the modem will tell you what exactly needs to be downloaded.
If the device has detected an accessory, but the driver installation has not started, and the Internet does not work, you should manually configure it.
Possible problems
Sometimes it happens that connecting the modem to the tablet ends up with the device perceives it as a USB flash drive or does not see the modem at all... The problem may be that the modem was originally designed for PCs or laptops, and tablet compatibility is a minor feature. In this case, the user needs to configure it in such a way that it is perceived by the mobile device only as a tablet, and not as a data carrier.
- You need to connect the device to a computer and install all the proprietary software from the disk from the package or directly from the memory of the accessory (different manufacturers offer their own options).
- After installing the software, you should enter it and see the settings menu. Among other things, there will be a "modem only" item. It should be activated.
- In addition, it is immediately recommended disable pin check so that it does not create additional inconvenience.
After completing these steps, connecting the USB modem to the tablet will not cause other problems.
Another item that may be found in different tablet manufacturers is necessary enable USB modem support... To do this, the user must enter the tablet settings and find the item "mobile data" or click on the button "more". In the submenu that opens, there will be an item "USB modem", it should be ticked off and save the data.
An important point to know about Yota modems is that it will not work until the user creates a tariff for himself. To start using the Internet from this company, you need to not only connect it to your tablet and set up a mobile connection. The owner needs to download the branded application from the Play Market. The registration of the SIM card will take place in it, a certain numerical code will be assigned to it (there is no subscriber number in the traditional sense), and after that the buyer himself configures the tariff parameters. After completing these steps, the Internet will start working.

"Android" via USB? Quite an easy way to access the Internet using an adapter. It can be either a standard YUSB wire or a more "advanced" OTG. The latter has its own peculiarity - it is not suitable for Apple tablets. Operating room tablets Android system have more possibilities for cable connection.
You can make such a connection using an adapter. Most tablets have the ability to directly connect to a modem using an adapter. To a greater extent, this applies to devices that run on operating rooms. Windows systems and Android.
Note! Tablets on the iOS operating system are produced by the American by Apple and have modest connectivity compared to competitors.
All of the tablet devices on the market (except iPad) have built-in USB ports for direct connection. Older models used the familiar USB 2.0 option. Newer models of devices can be equipped with compact micro-USB connectors.
Important! For the second case, you will need a special wire with an adapter.
In this regard, ordinary USB cables and ports look preferable.
As for special adapters, they are called OTG-wire or host wire. With its help, it is possible not only to connect the tablet to a modem, but also to use a mouse, flash card or other device.
Which modem to choose
In connection with the proliferation of tablet devices, the demand for 3G modems for Android and Windows is growing. Most of the tablets on these platforms are made in China and Korea, so they have the ability to work with modems, which, by the way, are mainly produced there.
However, the ability of the tablet to support the use and connection of the modem does not always guarantee correct operation. It often happens that one of the devices cannot be identified, or it simply refuses to function. The reason may lie in the wrong drivers or lack of settings. In addition, before purchasing and starting work, it is advisable to check that the modem complies with the following:
- ZTE MF-100;
- ZTE MF-112;
- ZTE MF-180;
- Huawei E171;
- Huawei E173;
- Huawei E352.
Connection
There are two ways to cable the tablet to the modem: via USB or OTG. It is desirable for every Internet user to know the principle of operation and settings of each of the presented ones.
USB
A large number of devices today are equipped with USB ports for just such cases. These ports are popular due to the compact size and battery-operated capability of the plug-in device. And the fact that many tablet devices do not have the ability to connect to the network using mobile internet, makes ports even more widespread.
In addition, many gadgets have a function for connecting to wireless networks called Wi-Fi, but it is not always possible to find a suitable access point. In such cases, 3G modems come to the rescue.
Thus, there are two ways to access the Internet from a tablet:
- Wireless network. You can use a portable pocket router to which the gadget is connected.
- Connecting a modem to the mobile Internet.
Most operators mobile communications provide their own modems for work. They have a built-in SIM card, are activated and ready to go. In addition, it is possible to purchase such a device from one of the world's manufacturers.
To connect, you need the following:
- Connect the modem to the tablet using the USB port, install the drivers.
- Switch the modem to "modem only" mode. To do this, you need to download and install the 3G Modem Mode Switcher program. Almost all of them are equipped with Zero CD technology (drivers are installed automatically). This prevents the Android system from correctly determining the port through which data exchange will take place.
- Launch the 3G Modem Mode Switcher program, and with the modem connected to the computer, click "Modem only".
- Insert the modem into the USB port of the tablet computer.
- Start the sequence "Settings" - " Wireless networks"-" APN Access Points ".
- In the menu that appears, enter the settings of the selected operator.
- Reload.
- Then insert the modem into the USB port of the tablet. After 10 seconds, a 3G symbol should appear next to the battery icon.
Important! Carrying out any manipulations with the device specified in this manual, the responsibility for its operability lies entirely with the user.
OTG
It can be decoded as USB On-the-Go. Represents a special opportunity for operating system"Android", which allows you to connect the gadget with other devices. This feature does not work with the manufacturer Apple. Installation and configuration takes place in this way:
- Connect all connected devices with a wire.
- It is necessary to wait a certain amount of time until both devices recognize each other.
- After that, you need to follow the sequence: "Settings" - "Data transfer" - activate the "Mobile traffic" slider;
- Go to the section titled "More" - select " Mobile network" - "Access point".
Connection rules
When connecting, you must take into account the following rules, which will help to carry out the operation more correctly and avoid errors:
- Check if the Wi-Fi module is disabled in the parameters of the tablet device.
- Check the activation of the "Wireless networks" parameter.
- Before connecting the modem, it is recommended to check its serviceability on a personal computer or laptop. He must have a connection with the operator.
- It is recommended to turn off the PIN code request function.
- When the modem functions normally with a PC, but refuses to work when connected to a tablet device, activating the "Modem only" mode in the settings can help.
- Also, the modem may not work due to low voltage. In this case, it is recommended to plug the gadget into an outlet.
Setting up work
For tablets that run on different operating systems, the sequence for activating and configuring the network is identical:
- The first step is to first find out information from the operator about the following parameters: username and APN. This can be done on the official website or with the help of the hotline support.
- You need to enter the device settings.
- Find in them and click on the item "Cellular network".
- Open the Data Transfer tab.
- Enter the obtained values.
- Return to the "Cellular network" and activate the slider for the cellular network and 3G or LTE standard.
Change of operating mode
When using a mobile network in the 4G standard, when the connection deteriorates, the gadget will automatically switch the operating mode to a lower standard, that is, 3G.
Note! In the same way, the mode will be downgraded in the case of the third generation, it will switch to EDGE. This will greatly affect the speed and quality of the signal.
If the connection quality is poor, then there is always an opportunity to connect wifi mode... To do this, turn off mobile communication and activate the wireless network. However, it is necessary that there is an access point available for connection nearby.
Network settings
For the modem to work properly, you need to enter the data of your mobile operator. This often happens automatically, but in the case of tablets, manual input may be required.
Note! Each of the domestic operators requires different values for APN, username and password. You can find them on the official website by calling hotline, or in internet sources.
One of the leading service providers Megafon has set the following values:
- APN: internet;
- Username: gdata;
- Password: gdata.
- APN: internet.mts.ru;
- Username: mts;
- Password: mts.
Beeline users can enter the following values:
- APN: internet.beeline.ru;
- Username: beeline;
- Password: beeline.
Tele2 subscribers enter the following:
- APN: internet.tele2.ru;
- Username: enter nothing;
- Password: enter nothing.
Operator Yota requires the following data:
- APN: internet.yota;
- Username: do not enter anything;
- Password: leave blank.
The small company MOTIV requires the following input:
- APN: inet.ycc.ru;
- Username: motiv;
- Password: motiv.
National telecom operator Rostelecom, data:
- APN: internet.etk.ru;
- Username: leave blank;
- Password: leave blank.
Possible problems and solutions
It happens that the modem refuses to work with the tablet. This may be due to the inability to support some of the operating system files and drivers. It is recommended to try to install "Terminal Emulator", it will provide root access for correct work equipment.
Note! Quite often, the inability to access the Internet can be a consequence of outdated version operating system or software. This can be fixed by updating them.
You can connect the tablet to the modem using special adapters. It can be a regular USB input or an OTG cable. In this case, you can get full access to the network.
All articles on our site are audited by a technical consultant. If you have any questions, you can always ask them on his page.
However, if both options are not available, you can use a USB tethering. This method is especially relevant for owners of models without a SIM card. How to connect a modem to a tablet? It's not difficult at all.
3G wireless settings
A modem for an Android 3G tablet is suitable for almost any modem that you usually use to visit the World Wide Web from a computer. The difference in connectors is compensated by an OTG cable (on the one hand, devices with a USB input can be connected to it, and on the other, there is a small connector for a device).
- First of all, turn on the gadget, wait for the launcher to start and icons with all applications appear.
- We go to "Settings" - "Wireless networks" - "Mobile network" (the sequence and name of the sections may vary depending on the device and OS).
- The third step: select the item "Data transmission" to enable the cellular network we need.
- We connect the modem to the tablet, wait until it is detected by the device (the inscription "3G" should light up at the top right).
- Next, select "APN Access Point" and create a new point.
If your modem is positioned as a product for one mobile operator, then everything is automatically configured. If this did not happen, enter the requested provider data:
- for Beeline -beeline.ru;
- for МТS -mts.ru;
- for Megafon - internet.
The username and password will be equivalent to the provider's name, you need to write down in English letters, as above, only for Megafon another is used - gdata. The MCC section is filled with the number 250 (for all operators), MNC:
- МТS - 01;
- Megafon - 99;
- Beeline -
Then you need to fix these settings and you can use the Internet.
How to connect a 4G modem to an Android tablet? Just like 3G: all parameters are exactly the same. Of course, when buying a wireless communication module, it will not be superfluous to mention the possibility of connecting it to a tablet: the consultant will set up the equipment or tell you which one is better to buy.
Potential problems and solutions
If after connecting the 3G modem to the Android tablet, the connection to the Internet does not work, then something is wrong. Possible problems faced by users:
How to connect a 3G modem if the obstacles cannot be removed? Apply to service center or to the salon of the mobile operator. You can also buy a pocket mini-router: it distributes Wi-Fi to connected devices, and also drains the battery less.
Maybe you know how to connect a USB modem to a tablet in another way? Share it in the comments.
Let's say right away that the use of a modern computer without high-speed Internet access today makes no sense. For a long time already, the computer ceased to be an independent autonomous device and began to act as a terminal for the World Wide Web. It is logical that tablets also require mobile Internet access. One of the ways to solve this problem is to use 3G modems.
Experienced users recall with a smile the distant times when computer technology was called "computing". It is hard to believe that the devices that have replaced the TV for modern people music Center and a bookshelf, as well as those that presented many unprecedented possibilities, were originally intended only for recalculating data arrays and other useful, but at the same time boring tasks.
The real revolution took place in the 90s of the last century, when, thanks to progress, computers became not only compact, but also relatively inexpensive. It is thanks to the progress that electronic computers have turned into multimedia platforms - the playback of audio, video and computer-animated content, as well as their combination.
At the beginning of this century, massive computerization also affected our country. Many people remember that in the early to mid-2000s, a “disco” - disk storage - was an obligatory attribute of a personal computer. For "advanced" users, shelves of disks with films, music and games made up a noticeable part of the interior. The problem of cluttering the living space was solved by itself with the advent of high-speed Internet access, which made it possible not to store data on external media, and "download" them as needed, or even play them online.
New tasks were set by the massive use of mobile computers - laptops, smartphones, etc. If you can still connect the cable of the "wired" Internet to the laptop, then the very idea of tablet mobility is "killed" by this method of connection in principle. A smartphone, "strung" on a cable, would look completely stupid.
It would seem that the problem of mobile access was solved with the advent of Wi-Fi technology - two-way signal transmission over short distances, which communicates between an Internet cable and one or more devices. makes it possible to move with the tablet around the apartment or office without losing connection with the Internet.
However, in the life of every tablet owner, sooner or later there comes a moment when, due to life circumstances, you need to get off the short leash of Wi-Fi. It doesn't matter if it is connected with a trip on vacation, moving or changing work, but one day the tablet user is no longer enough. 3G modems allow you to stay truly mobile.
We connect the 3G modem to the tablet
Modem - a device for connecting a computer to a wired telephone network seemed to be out of date. Nevertheless, modems have received a new lease of life thanks to devices that can connect mobile computer gadgets to the Internet using a cellular network. These devices are also called modems. Thus, access to the Web is carried out wherever mobile communications are available.
What is needed in order for your mobile computer- Android Tablet - Become Really Mobile?
- Firstly, the Android tablet itself must be equipped with a USB or micro-USB port. When in doubt, check the markings on the case. USB ports(it does not matter, standard or micro) are marked with a characteristic icon - "trident".
- Secondly, if your Android tablet is equipped with a micro USB port, then you will need a special adapter cable between the micro USB port on the tablet and the standard USB that the modems are equipped with. Typically, this cable comes standard with an Android tablet. If you purchased the tablet from your hands or the kit is lost, then we advise you to purchase this cable. When buying, be sure to specify that you need a "host" (or OTG) cable. It is such a cable that is required to connect external devices to the tablet. The "client" cable (client) is needed to connect the Android tablet itself as external device(for example, to a PC) for data exchange or recharging.
- Thirdly, you will need the mobile USB dongle itself. Consider these devices.
Which modem should I choose?
Mainly in the market mobile modems 2G and 3G USB modems are presented today. We will not delve into the differences between generations of mobile communications, let's briefly say the most important thing. A 2G modem is cheaper, allows you to use a regular 2G sim card from your phone and is suitable as a means of emergency Internet access. If, for example, the "fixed Internet" is turned off, you can send an urgent letter or answer a message in Skype, but only in text mode - you can forget about video communication and streaming video with a 2G modem.
It is the 3G modem that allows you to access the Internet at a sufficient speed, therefore, it is recommended to use this option for a permanent connection of an Android tablet to the Network. If you purchased a 3G modem in a mobile phone store, Megafon or MTS, then, most likely, the device will be "flashed", that is, you cannot change the operator with whom you have entered into a contract. But the modem itself will cost you a little less. You can purchase an "unprocessed" modem and buy a 3G sim-card, Beeline or Megafon separately. What's better? There is no definite answer to this question, you must take into account your needs and conditions of mobile operators in your region.
Step one
If you already have everything that we have listed, and most importantly, ready to go, we proceed to the connection. Initially, 3G USB modems were intended for personal computers, therefore, to bring the MTS, Beeline or Megafon modem into working condition, we need a PC.
Connect the modem to the PC, install the bundled modem software- driver programs and special applications to configure the modem. The software can be recorded on the supplied CD-ROM or on the drive of the modem itself.
For the modem to work correctly with an Android tablet, you need to switch the 3G modem to "modem only" mode. It is also recommended to disable PIN verification. You can do both using the app included in the software suite. In a set of modems, "flashed" mobile operators Megafon, Beeline or MTS, as a rule, are supplied with Russian-language applications, which greatly facilitates the configuration of a 3G modem.
For your information: if you do not have a PC, you can configure the modem directly using the Android tablet to which the modem is connected. To do this, you need special applications such as 3GSW. However, this app is not included in the list of verified content distributed through Google market, and you will use it at your own peril and risk.
Step two
In the tablet settings, go to the "Network Settings" section (in different models the items and sections of the menu can be called differently) and activate the items "Data transfer" and 3G. We connect the modem to the tablet, we are waiting for the moment when the light on the modem case stops blinking.
Next, you need to go to "Additional settings" and create an access point using the item "APN access points". You can clarify the settings with the consultant of the mobile operator Beeline, Megafon or MTS, depending on which network you have chosen for your Android tablet. If you purchased the modem at a certified point of this operator, then all the necessary data will already be installed.
Save settings and reboot Android. If everything is done correctly, after rebooting, you will see a 3G icon at the top of the screen. Check internet access in your browser.
Conclusion
An important point: Android tablets that do not have a built-in GSM-module (if there was a module, you would not need a modem), there may not be an interface necessary for connecting a 3G modem. In this case, download from the store Google play free program PPP WidGet https://play.google.com/store/apps/details?id=de.draisberghof.pppwidget.
It will allow you to get drivers for different models of 3G modems.
"Kroilovo leads to a popalov" is a well-known fact.
I got myself a tablet without a 3G module in order to save money Money... "At work, at home, in a cafe, in shopping centers- Wi-Fi ", I thought and saved. But in vain. On the tracks, in villages, fishing and other barbecue, Wi-Fi is absent. Of course, you can poke into the smartphone screen, but it is more convenient and pleasant to poke into the tablet screen. This issue must be resolved. ...
So, we have an Android tablet ( Texet TM-7854) and 4G USB modem ( Megafon M150-1, Huawei E3276). All modern Chinese cheap wretched tablets have a USB-host on board, which allows us to think about pairing these devices.
Of course, nothing will work out of the box, so you have to wiggle your fingers a little:
1. We receive on the tablet root access(for each manufacturer and model our own crutches, we are looking for w3bsit3-dns.com and gsmforum.ru), install a terminal emulator, file manager with full access to file system and hot remount capabilities such as Root Explorer. This completes the preparation of the tablet.
2. Go to the USB modem. It must be switched to " Modem only ". Download and install DC-Unlocker on your computer. We connect the modem to the computer. Open DC-Unlocker, click Detect modem. If the modem is detected, then the information about the piece of hardware will be displayed in the program window.
Now we transfer the modem to the mode we need with the AT command. Disable the CD-ROM and Card Reader functions, because Android does not understand composite USB devices, or rather, it understands them and dmesg speaks eloquently about it, but does not want to work with them, bitch.
Enter the command into the DC-Unlocker window AT ^ SETPORT = "A1; 1,2" if we get OK in response, everything is correct. Now the device works only as a modem, faster and more stable.
Note: if you suddenly need to return all device functions, enter the command AT ^ SETPORT = "A1; 10,12,13,16, A1, A2"
3. We return to the tablet.
Editing the file /system/bin/preinstall.sh, add the line to it
echo "vid pid"> / sys / bus / usb-serial / drivers / option1 / new_ id
where vid and pid are the values of your usb modem. They can be viewed in the device manager when the modem is connected to the computer. In my case Vid = 12d1 Pid = 1506
We reboot the tablet.
4. Now our tablet sees the modem and knows how to work with it. You just need to find out on which port our piece of hardware is seated
We connect the modem to the tablet with an OTG cable (comes with all tablets more than two thousand rubles), wait 10-15 seconds for the modem to hook to the nearest BS.
We open the terminal and give commands
su
dmesg
We are looking for a line containing "GSM modem ...... ttyUSBx" in the output, x is the port number on which the modem sits, for example ttyUSB0, we remember this value.
5. Download GScriptMod, install.
6. Create a gscript folder on the memory card and add these files there: once or twice.
We edit the first file and change the port value there to the one you received
.......................................
if [-c / dev / ttyUSBx]; then
.......................................
.......................................
7. Create a directory / etc / ppp / peers, add a couple more files there: once or twice
V conf-pppd change ttyUSBx, enter the username and password, for our example the file will look like this:
defaultroute
noipdefault
