MTN recently celebrated the Christmas with their customers by giving out a wonderful bonus from their Game+ to over 500 people on their network and a free N500 Airtime credit .
Game+ gives you access to enjoy both local and international games on your Android device and many other phones including Java. Their service is extremely good because if you like game, you must surely like Game+.
Those who have activated the Game+ offer but unable to use the data on their Psiphon VPN, can now use it on their Stark VPN application with the help of this tutorial.
STEP 1: Firstly, download stark VPN app on playstore by clicking here and launch the app.
STEP 2 : Tap on “ CUSTOM ” and apply the following settings:
* Select Connection Mode: HTTP
* Server Port: 80
* Host Header: X-Online-Host
* Select Header Line Type: Singleline
* Tick the Reverse Proxy
* Proxy Server: game.mtnonline.com
* Proxy port: 80
STEP 3: Now, go back to your homepage, in the “ TWEAKS “, kindly choose “ CUSTOM “, switch on your data connection and tap on the BIG RED BUTTON to connect.
That’s all, Enjoy!!!
