Two things decide whether the money comes back. The first is whether the stranger has already taken it out or spent it. If it is still in their wallet, there is a chance. If it is gone, only that person can repay you. The second is who pressed send. You paid from an app abroad, so that app has to ask for the money back. Your family at home cannot do it for you, and the wallet's own reversal tools were not built for your payment.
Which case you are in
- The number has no wallet on it. Nobody can receive the money, so the payment should fail and come back to the app. GCash, for one, says it can reverse money sent to a number that is not in use.
- The number is a stranger's wallet, and the money is still there. This is where speed matters. The money can come back if the stranger agrees, and your app has to start that request.
- The stranger has already taken the money out. There is nothing left in the wallet to pull back. Only the stranger can repay it, by choice or with the police involved.
- Your family sent it from their own wallet at home. That is a different case with its own tools and a 24-hour clock. It is covered under each wallet below.
You will not always know which case it is at first. Treat it as the second one and move fast.
The first hour, in order
- Take a screenshot of the transfer in your app: the reference, the amount, the time, and the wallet number you typed.
- Contact the app through its in-app chat or help page. Say: "I sent money to the wrong mobile wallet number." Give the reference, the wrong number and the right number.
- Ask the app to contact the company that paid the money out in that country, and to ask the wallet company to hold the money.
- Ask for a case number and write it down with the date and time.
- Send the wrong number to your family, so they stop waiting and know the number if it calls.
Why the app, and not the wallet? Because on each wallet, the quick fix belongs to whoever sent the money from inside it. On M-Pesa, forwarding the payment SMS to 456 reverses a payment only when one Safaricom customer has sent to another. Money from an app abroad does not arrive that way. GCash says it plainly: when another company pays money into the wrong GCash number, that company has to ask, and GCash cannot start the refund without it.
What each wallet can do
M-Pesa in Kenya
Safaricom's own reversal page sets the limits. Only the sender or the receiver of the payment can ask. The request must come within 24 hours. The receiver must still have enough money in the wallet. There are at most three tries per payment. Those rules are written for a send from one M-Pesa wallet to another inside Kenya.
Catch
Your mother cannot reverse your payment from Nairobi. M-Pesa lets only the sender or the receiver ask for a reversal, and the sender of money from abroad is the app you paid with. Start with that app.
When a receiver refuses, Safaricom has told customers to contact the receiver directly or report it to the police. 
K24 reported that reply in July 2026, and that Safaricom cannot remove the money once the receiver disputes the reversal.
GCash in the Philippines
GCash says Send Money moves in real time. It can only reverse a payment if the receiving account is inactive or not in use. For a live wallet, its advice is to ask the person to send the money back. For an old number, you can ask in the app (Transactions, tap the payment, Get help, "I sent money to the wrong number"), and GCash says it answers in one to three business days.
For money paid in from outside GCash, the company you paid has to ask. GCash asks for any dispute within 15 days of the payment. Do not let your app's queue use up those days. The GCash wallet guide shows how to check the number before you send.
MTN MoMo in Ghana
MTN lets the sender of a MoMo payment ask for a reversal: dial *170#, choose 6 (My Wallet), then 8 (Reversal), and pick the payment. In the MoMo app, the request must be made within 24 hours. The receiver gets a prompt to approve it. If they refuse, MTN asks you to email [email protected], and says it will hold the money in their wallet and start its normal reversal process.
Watch one clock here. MTN says that if a reversal is refused and nobody contacts it within 24 hours, the money is released to the receiver after 30 days. These tools work from the wallet that sent the money, so for a payment from abroad, your app has to make the request. The MoMo wallet guide covers getting the number right.
What your app can and cannot do
Once the money is paid out, most apps cannot pull it back on their own. Wise says that if a transfer shows no cancel button, the money is out of its system, and you need to contact the person who received it. Remitly lets you cancel for a full refund only before the money is paid in or collected. Sendwave says in its help page, in the answers for the Philippines, that there is no automatic way to recall money sent to the wrong account: its partner has to contact the wrong account holder, and that person has to agree to pay it back.
If you paid from the UK, the law asks more of the app. It must make reasonable efforts to recover the money. It may charge you for this, but only if its terms say so. If it cannot recover the money, ask in writing for the information you would need to claim it yourself. The app must give you what it has. Remitly's UK notice also asks you to report an error within 180 days of the promised delivery date.
If you paid from the US, you have 180 days from the promised delivery date to report an error, and the app has 90 days to look into it. When a sender types a wrong account number, the app can leave the loss with the sender only if it warned them before they paid and then moved quickly to try to get the money back. Ask, in writing, what the app did and when.
If you paid from the Gulf, ask the app in writing what its terms promise when the number is wrong, and keep the answer.
If the stranger will not give it back
Keep everything: the app's receipt, your screenshots, the case number, and any message where the person refuses. If you go to the police in Kenya, take all of it with you.
Warn the family about one trick while this is going on. Scammers send a fake payment message, then call to say "I sent you money by mistake, please send it back". It is the same mistake you made, faked on purpose, and no money was ever sent. If someone calls like this, the family should check the wallet balance, not the message. The M-Pesa scams guide has a version to send home.
If the mistake was a bank account number and not a wallet, the rules are different. The bank version of this page covers it. Every other transfer problem, from a "complete" that never arrived to a name that does not match, is under transfer help.
