With the new MTN Collect SMS, you can now stay in touch no matter what. This service allows MTN customers with low airtime, or those who do not want to pay for sending a particular text message, to send an SMS to another MTN customer free of charge. The receiver however, must accept charges for the inbound message.
The service thus affords an MTN customer (the recipient) to bear the cost of an incoming SMS from another MTN customer (e.g. family, child, employee, friend etc.).
Simply send your SMS to 38701 followed by the receivers phone number e.g 38701080312348678
NOTE: This service is only available for MTN to MTN customers.
