It looks like MTN has succeeded in tracking down their Bis plans as it's refused to work on PC and Android devices since yesterday 13/3/2015 around evening. I'm pretty sure that the PC and Android device users enjoyed the Mtn Bis tweak, now the Mtn Bis plan has exclusive for BB users only. Nothing is permanent in this life.One thing I know is that this is not the end of using Mtn Bis on PC and Android devices. The loophole will continue to exist in all telecommunication systems. Don’t worry guys, I will always update you about the latest info. Just let be patient for a while, another alternative will be provided very soon.
