MTN 150MB Without Tweaking

Step 1: Send an sms APP to 131. Wait for a confirmation message welcoming you to the free 150mb app data.
To check balance, send CHKBAL to 1131
Note: In case you get that you can't be given more than once, send CHKBAL to 131 to know your remaining balance

Step 2: Configure  your Simple Server by just replacing the 
***Injection query url: http://nextapps.mtnonline.com
***Injection host: nextapps.mtnonline.com. 
 Leave all the other settings

For Psiphon, change your 
***Proxy server: nextapps.mtnonline.com"  and use the other settings.
Thats all.
