UPDATE......
Mtn bb10 subscription is now working, what happened was network glitches due to system upgrade, so the bb10 mini is bblite.
For the bblite just dial this code
1. For Daily sub dial *216*3*1# @ N70
2. For Weekly sub dial *216*3*2# @ N350
3. For Monthly sub dial *216*3*3# @ N1000
And to those of you who got error replies while trying to subscribe.. [don't worry if your money was deducted without confirmation] just verify by sending "status to 21600" and you should be able to see 5120mb which shows that u have 5gb of data left..[like shown in the pics below]
