I have noticed this on the MTN network and at first thought I was the only one affected, but I've discovered that a lot of us are complaining of the same thing too and nobody seems to be getting a satisfactory answer:
If anyone knows why subscription on the MTN network seems not to be working/it works for a little while and then stops, please enlighten us.... Instead of your subscription to keep running, your airtime is used up. Yet when you try to re-subscribe, you're told that your previous data is still in use.
Anyone who knows what's up with the network should pls enlighten us.

Secondly, I heard that MTN is no longer offering unlimited data plan. If true, is there any network still offering the Blackberry UNLIMITED data plan?
Thank you.
