How to connect Android tablet to 3G-modem. Connect 3G Modem to Android

Probably, every owner of the tablet is familiar with such a situation, when the Internet is urgently needed, and there is not a single Wi-Fi signal near it. In this case, only the modem and the 3G module help. But if you do not have the latter, do not worry, because most modern tablets can work with a modem and through an ordinary OTG cable. How to connect Android tablet to 3G-modem? Read more about this in our article.

Modem properties

First, a couple of words about what this device represents. 3G-modem - a receiving-transmitting element, which serves for data exchange over a radio channel. Each 3G-modem is connected to its mobile operator.

In terms of their capabilities, these elements are capable of transmitting information at speeds up to several megabits per second. In addition, unlike the cable Internet, the network on the modems "catches" almost everywhere, where there is a mobile connection. Therefore, such devices are indispensable for those who often travel and travel on a business trip. Some tablets have a connector - a module for reading SIM-cards. In this case, the tablet itself works as a modem, without additional settings (except for basic ones). The communication range itself can be the most diverse - WCDMA, UMTS, HSDPA, and also HSPA +. But if such a module is not available, you have to work hard to connect the modem to the gadget via the OTG cable. In principle, the connection speed and data quality in both cases are the same. The only difference is that without a module for SIM cards it is necessary to connect the modem directly through a short cable to the device, and this gives some inconvenience with frequent use of the Internet.

Features of tablets

Let's find out what elements the modem consists of. This element includes two main components: a flash drive that stores data for the connection, as well as the 3G module itself. And if laptops and PCs automatically recognize these two details, the tablets most often see the modem as an ordinary USB flash drive. In order for your gadget to recognize it correctly, you need to perform some simple manipulations. We will describe them in the following paragraphs. By the way, almost on all tablets such as Android tablet 3G-modem USB type is connected via OTG-cable. This is a universal USB-cable, through which the gadget can recognize and read any flash drives, make and copy any information.

How to connect 3G-modem to Android? Switch to "only modem" mode

There are two main ways by which you can adjust its work in the right direction. Let's consider the first of them. For this we need a 3GSW program and a computer. Download this utility on your PC. Next, insert the modem into the connector and open the program. In the menu that appears, click the "only modem" button and click on the output. As you can see, the method is quite simple. However, it has one significant disadvantage - it does not work on all modems. In this regard, consider an alternative method of transferring to the "only modem" mode.

To do this, we again need a computer and Internet access. Download the trial version of the utility HyperTerminal. Then we connect the modem to the computer, start the Windows device manager . In the list of equipment we find our 3G-element and turn to its properties. How to connect Android tablet to 3G-modem next? Next, select the button "modem" and rewrite the speed and the number of its port. After we start HyperTerminal and specify the connection name in the connections (it can be arbitrary). Then, in a new window, enter the rewritten port number, the connection speed and click "ok". In the opened tab we write the command "ate1", and then "at ^ u2diag = 0". We wait, while there will be an answer "ok", we disconnect the modem.

Root-rights

In order for our modem to work in the future co-correctly, we need to open Root rights. What it is? Root is the login for the user's account. In this case, this is the "admin". Simply put, these rights give us all the capabilities of an administrator (as in the Windows operating system):

1. Editing system files.
2. The right to change the visual design of the OS "Android", the replacement of shortcuts.
3. Save and change the settings of system applications, as well as their backup.
4. The right to delete old and install new applications.

Connecting 3G modem to Android - how to get administrator rights?

The first method is the most popular - its essence is to use certain programs. However, it should be noted that they all have their own list and their limited number of supported devices. The most popular of them are:

• Kingo Android Root.
• Unlock Root Pro.
• Super One Click (ideal for Android 4.0 operating systems).

3G-modem can be connected by another method. It is to use android applications. The main advantage of this method is that there is no need to use a personal computer, as in the first method. The whole process of rutting is done using only the tablet itself, without additional devices. The most popular android applications for rutting:

• Universal AndRoot.
• Z4root.
• Framaroot.

It is worth noting that most programs of this type for exploiting administrator rights use vulnerabilities of the system - exploits. Because of this, antivirus programs installed on the tablet can perceive the work of these utilities as a threat and block their action. However, this is not true - all programs are absolutely safe and harmless (of course, provided that you download them on sites that you know well).

The next method will be to install the firmware already with the activated administrator rights. Most often, in addition to Root-rights, they have a number of other improved modifications. The most popular utility is CyanogenMod.

This program allows not only to expand the user rights, but also allows you to change all system settings. It:

• Status bar.
• Quick Settings Panel.
• Topics.
• Lock screen.
• Buttons on the panel of external controls.
• Panel and navigation bar.
• Arrangement of external labels.
• Expansion screen.
• Sound settings, music effects.
• Configuration of profiles and screen.
• Language settings and input.
• Additional menu with device parameters.
• Clock widgets, event indicators and many, many other useful functions.

Change the tablet settings to work with the modem

So, we already have administrator rights. How to connect Android tablet to 3G-modem next? To do this, we need to download the PPP Widget application in the Play Store and install it on the gadget. To make it more convenient for us to work, create a small shortcut on the desktop with the installed program.

Further on the site of the developer of the utility we find the driver specifically for its brand and model of the tablet. The driver should be placed in the folder at the address "sdcard / pppwidget / lib". Then connect the modem with the OTG cable and go to the settings menu of the widget "PPP Widget". We find the section "Connection settings" and prescribe all the settings that were provided by your operator (access point, etc.). We save the settings and try to connect to the Internet. After reconnecting the modem in the tablet, the Internet should appear. Also, on the main background, a small "3G" icon will appear on top, as shown in the photo below:

What if the Internet does not appear?

In this case, you need to determine whether the modem is in the list of supported for your tablet. If it is incompatible, you will have to replace the modem with another one, which is in this list.

Conclusion

So, we figured out how to connect the Android tablet to the 3G modem with their own hands. As you can see, you can configure and connect the modem to the gadget in a few minutes. But most importantly, in order to connect Android 3G-modem USB, you do not need to have special knowledge in the computer field and special tools.
