Hello
The MTN mobile wallet in Ghana has a daily 5000 cedi limit.
As such, if you have sent more the transaction will get canceled and return.
The transfer will return to your dollar Neema account. The dollar balance is next to your shekel balance. Look for the American flag.
You also need to make sure that your receiver has space in his MTN wallet to receive the transfer since there is a limit on the balance as well.
Here is a great local GHANA website where you can read about the limits and check in which tier your receiver is situated:
thank you
