Make sure your sim is upto 1yr above accordin to
my own perception, migrate to mtn ipulse, load any
amount, dial *131*5*1# once, then sav this
number on your contact
*123*3*1*5*2#1 and keep dialling.
The more you dial it, the more GB you get.,
*Check your GB with
*131*4#...
NOTE: you might be seing transaction failed but
don't panic,just keep dialing the code or use
another sim.
But if you see "Thank you for using
our service." just check your data...
Enjoy!
