How to connect USB modem to an Android device

People who have tablets without 3G support might find the need to use these dongles with their device to get something downloaded quickly when the broadband is down. This can be done using an Android app called PPP Widget 2. As the name suggests, it is a widget, not an app.

It is available in the Play Store and it is free. You will need to be rooted and you must have a USB OTG cable.

What you need ?

A rooted Android device,
PPP Widget 2
OTG USB Cable
Internet Modem with a SIM Providing internet connection
APN and other credentials provided by your ISP

1.Once you had above mention things you are ready to go, first download and install PPP Widget 2 on your rooted android device and place it on your home screen for easy access.

2.Now connect your 3 modem to phone via OTG Cable and grant root permission, in few seconds it will recognize your modem.

3.First you need to configure your modem with your APN and other credentials by tapping the configure button on the widget. Once done click on Connect and within few seconds you will be connected to internet.
