I have been using mtn for over a decades now with good and strong connection.
I am using beta talk tarrifs and I receive double money based on my recharged amount,I remembered the day I was out of airtime and I needed to follow up my son going for NYSC in Niger state,my elder son told me I could borrow money from MTN,extra time...I did and it helped me follow up with my son.
MTN thank you oo
