For almost a year I have been unable to send or receive sms on my airtel line. On bb, phone will show - requested facility not implemented.
I have called customer support many times, even physically visited their office twice, no solution. Recently, sim got lost, I recovered number with new sim, still problem persist and still no solution.

So I am thinking of porting to mtn when my bis expires, any suggestions?

No! Airtel is better o

You will port back to Airtel again later

This is a serious matter o, guess i should just wait here. . .
