Do you know you can get upto 1500 worth of airtime to call and send sms with no restrictions for only N500 on MTN Nigeria which i will be sharing with you as MTN sent a message to tell me about how to get 1500 worth of airtime for N500 to call and send text messages.
Just4U! Pay N500 & Get N1,500 worth of airtime to call,text & browse. dial *142# to get the offer valid for 7 days. No Auto renewals
The above is what i recieved from MTN so i suggest you try it if you make calls a lot because this one can be called "MTN Call awuf"
