It is one of the most common mobile money scams in the world. A text arrives saying you received money. Minutes later, a stranger calls, upset: they sent it to the wrong number, please send it back. The money never arrived; the text was fake.

Step by step

  1. The fake alert: an SMS that looks like a deposit notification, often from an ordinary number.
  2. The call: an apologetic or panicked caller, sometimes using your name.
  3. The pressure: it is their school fees, rent or hospital bill.
  4. The request: send it back to "this other number", or approve a prompt.
  5. The loss: you send your own money.
Illustrative example · SMS from an ordinary number
You have received 450.00 from JOHN K. Transaction ID 8841X29. Your new balance is 452.30.
Red flags: it comes from a normal phone number, not the provider's sender name, and your app shows no change.

What to do

  1. Check your real balance in the app or official menu. See checking your balance.
  2. Do not send anything back, even if money really did arrive.
  3. Tell the caller to contact the provider for an official reversal.
  4. Report the number to your provider.

Genuine mistakes are reversed by the provider, not by you sending money to a stranger's "other number".

Frequently asked questions

What if someone really did send me money by mistake?

Let the provider handle it. The sender can request a reversal through official channels. You do not need to send anything yourself.

The caller is crying and says it's their rent. What should I do?

Stay kind but firm: tell them to contact the provider for a reversal. Check your real balance in the app or menu.

I already sent money back. Can I get it back?

Call your provider immediately with the transaction ID and report it as fraud.
