I decided to try some tricks to make it work
To do this, we will use some files which I have provided download links for.
How To Do It
=> Download the above file and keep it safe before you proceed below .
Start the 3G/4G optimizer :
Choose network speed as 12/28/7(set to max)
=>you’ll select down speed increase
=> then apply the changes made .
=> You’ll Restart the device once you save the changes
=>Then Open the script manager
Browse the file which you downloaded (ie) 3G Turbo script text file changer
=> Allow the Super User (grand Permission)or else click on the Super user icon , grant permission and run the script
Scroll up and set the setting to Fastest to get the maximum Data Speed .
Reboot your device
=> Switch To WCDMA Mode on Setting(network)
1. Your device must be rooted to make this trick work.
2. Reboot where ever its required .
Now you can enjoy 3g speed on the airtel 2gdata plan
