A stolen phone with a banking app on it is a banking emergency, not a phone problem. The order in which you make the next few calls decides how much it costs you, and most people get it backwards by phoning the network first.
The reason the order matters is the one time PIN. If the thief still controls your number, they can receive the codes that authorise payments, add beneficiaries and reset passwords. Blocking the bank profile closes that door immediately; blocking the SIM takes longer and does not undo anything already done.
ContactDetails.co.za is an independent directory. We cannot block anything for you. This page is the sequence and the verified numbers, so you are not searching while it is happening.
Do these in this order
- Phone your bank’s fraud line and ask for the profile and cards to be blocked. Say “my phone with my banking app has been stolen” in the first sentence. This is reversible and it is the fastest protection available. Ask for the incident reference before you hang up.
- Phone your mobile operator and block the SIM. This stops calls, data and any one time PIN sent by SMS. Ask them to note the line as stolen, which also protects you from charges run up on it.
- Change the passwords for the email account linked to your phone, from another device. Email is the recovery route for almost everything else, so a thief who reaches it can reset banking, retail and social accounts in turn.
- Report the theft to the South African Police Service and get a case number. Insurers and banks commonly require one, and the case number is also what you need to blacklist the handset.
- Blacklist the handset with your operator using its IMEI number, which makes the device unusable on South African networks. The IMEI is on the box, on the original invoice, and in your account with the phone’s maker.
- Check the account afterwards, line by line. Look for new beneficiaries, changed limits, changed contact details and small test payments, and report anything you did not do.
Bank fraud lines

SIM swap fraud, which is the same attack without the theft
A SIM swap achieves what stealing your phone achieves, without anyone touching it. The fraudster persuades your operator to move your number to a SIM they hold, and from that moment every one time PIN sent to you goes to them. The warning sign is your phone losing signal for no reason and staying dead while other phones nearby work normally.
- If your line goes dead unexpectedly, treat it as an attack until proven otherwise. Phone your operator from another phone and ask whether a SIM swap or number port was requested.
- Then phone your bank, even if nothing has gone missing yet, and ask them to note the account.
- Move off SMS one time PINs where your bank offers an alternative. In-app approval and authenticator apps are tied to the device rather than the number, which is what makes them harder to hijack.
- Keep your banking app locked with a separate PIN or biometric, not the same code that unlocks the phone. A thief who watched you unlock the handset in a queue has the phone code already.
What the bank can and cannot undo
- It can block the profile and the cards immediately, and it can reverse that block once you are safe.
- It can log the matter as fraud and open a claim, which is a different process from a service query and starts from the moment you report it.
- It cannot recover a real-time payment that has already cleared by pressing a button. Recovery depends on the receiving bank and on whether the money is still there, which is why minutes matter.
- It will never ask you for your PIN, password or a one time PIN when you phone in. If someone rings you back claiming to be the fraud department and asks for those, they are the fraudster.

Complaints and escalation
If the bank refuses a fraud claim, ask for the decision and the reason in writing. Then take it to the National Financial Ombud on 0860 800 900, which now handles banking, credit, life insurance and non-life insurance complaints in one place. It is free to consumers. It will want the date and time you reported the theft, the incident reference, the police case number and the bank’s written answer, which is why the first call should always end with you writing down a reference.

Frequently asked questions
Should I phone the bank or the network first?
The bank. Blocking the banking profile stops payments and beneficiary changes immediately. Blocking the SIM matters too, but it does not undo anything the thief has already authorised, and network queues are usually longer.
My phone was stolen but it was locked. Am I safe?
Safer, not safe. Screen locks are worth having and they defeat most opportunistic thieves, but a thief who watched you type the code, or who can still receive your SMS one time PINs through the SIM, does not need to unlock the app to do damage. Block both.
What is an IMEI number and where do I find it?
It is the handset’s unique serial number, and operators use it to blacklist a stolen device on South African networks. It is printed on the phone’s box and on the original invoice, and it is recorded in your account with the phone’s manufacturer.
The bank says the transactions were authorised with my OTP, so it will not refund me. Now what?
Ask for that decision in writing, with the times of each transaction and the times each OTP was sent. Then take it to the National Financial Ombud on 0860 800 900. Whether a customer was negligent, and whether the bank’s own controls should have caught the pattern, are exactly the questions the ombud exists to weigh up.
Do I need a police case number?
Get one. Banks and insurers commonly require it before finalising a claim, and blacklisting a handset is easier with one. Reporting also costs you nothing.
