How to Retrieve a Lost MTN SIM Card: 7 Steps in Order

Block it, protect your bank, then retrieve the number with your NIN. Includes proxy rules.

If your SIM was stolen, do this first: block the line, then tell your bank. Retrieving the number comes after. Anyone holding the SIM could read your SMS codes.

7 steps in the right order

1Block the line. MTN says you can dial *123*7*4# (or *123*7# and choose option 4) to block a stolen line. Use another MTN phone if you can. You give the number and answer security questions.
2Warn your bank. If your BVN, NIN or bank alerts are on that line, ask the bank to protect your accounts.
3Get your ID ready. MTN needs your NIN or Virtual NIN, and the number must be registered.
4Prepare answers. MTN may ask for your last recharge amount and date, three frequently dialled numbers and the year the line was activated.
5Visit an MTN store or authorised outlet. You buy a new SIM, and your old number is moved to it. A token fee applies.
6Check the new SIM. Dial *310# and test a call. Reinstall or re-verify banking and messaging apps.
7Report it if needed. MTN suggests a police report if the SIM was stolen and fraud is possible.

If you are abroad or cannot go

MTN allows a proxy swap. Both you and your proxy need a NIN. The proxy must be an MTN customer for more than 30 days with a valid NIN, and must bring hard copies of your documents, proof of ownership (the SIM pack, eSIM QR profile or an affidavit) and a signed request letter. MTN asks you to email its support team first so the store knows to expect the proxy.

Self-service option

A recent guide reports a self-service swap in the myMTN app for eligible prepaid customers. It needs a blank unregistered MTN SIM and face verification against your NIN record, and it sends you to a store if verification fails. Confirm that it is available for you before you rely on it.

What can delay you

  • A NIN that does not match MTN’s records.
  • A number that is not registered.
  • Wrong answers to the usage questions.
  • Going to an unofficial shop. Use MTN stores and authorised outlets only.
After the swap: your old SIM stops working once the number moves. If your working SIM suddenly loses signal and you did not swap it, call 300 straight away, because someone may have swapped it without you.

How much is the fee?

MTN calls it a token fee and does not list one fixed amount on these pages, so ask in store.

Will I keep my airtime and data?

The number moves to the new SIM. Ask MTN what happens to balances on your line.
