Direct answer
Take your network’s customer care number from your own invoice, your SIM starter pack or the operator’s website typed in by hand. Every major South African network publishes a short dialling code you can reach from your own handset, which is the safest route of all because it never leaves the network. A telecom support number that arrives by SMS, appears only in a directory, or is offered in a social media reply to your public complaint has not been verified by anyone. Verified 18 August 2026.
Why telecom impersonation is worth more than it looks
A fraudster impersonating your network is rarely after your airtime. Your mobile number is the delivery address for one-time passwords, so control of it is control of your bank accounts, your email and anything else secured by an SMS code.
- A SIM swap moves your number to a new SIM. If that is done in someone else’s hands, your one-time passwords go to them, and your own phone loses service.
- The call is usually the setup, not the crime. A caller claiming to be from your network asks for the details or the code needed to authorise the swap.
- Your handset going dead is the alarm. A sudden and sustained loss of signal, when others around you have service, deserves an immediate call to your network from another phone.
That last point is the single most useful thing on this page. If your phone loses service unexpectedly and stays dead, treat it as a possible SIM swap and contact both your network and your bank straight away rather than waiting to see whether it comes back.
The pretexts used
- “Your SIM must be re-registered or it will be deactivated.” Registration requirements are handled through your operator’s own channels and stores, never through a link or a caller who contacted you.
- “You have won a data or handset prize.” A prize requiring a fee, a code or your banking details is not a prize.
- “We are upgrading your line and need to verify you.” Upgrades do not require a one-time password read aloud.
- “Your account is in arrears and the line will be cut today.” Check the balance through the operator’s app or short code instead.
- A reply to your public complaint offering to help by direct message from an account using the operator’s logo.
How to get a genuine number
- Use the short dialling code published by your network for calls from your own SIM. It cannot be redirected by a search result.
- Check your monthly invoice or statement, which carries the operator’s published support details.
- Use the operator’s own app, where in-app support routes you without a number at all.
- Type the operator’s domain and read the contact page, rather than taking a number from search results or a directory.
- Visit a branded store for anything involving SIM replacement or identity, which is the hardest route to impersonate.
Official escalation channels
| Route | Detail | What it handles |
|---|---|---|
| Your network | Short code, invoice or official app | SIM, account and line matters |
| Your bank | The number on the back of your card | Securing accounts after a suspected SIM swap |
| ICASA | 012 568 3000, [email protected] | Conduct of a licensed telecoms provider, after its own process |
| SAPS | 10111, or any station | The criminal case and case number |
| SAFPS | 011 867 2234 | Protective Registration if identity documents were used |
ICASA licenses telecoms providers and handles complaints about their conduct, but only after the provider has been given a fair opportunity to resolve the matter. It is a regulator rather than a fraud investigator, so a criminal loss still belongs with SAPS and your bank.
Urgent steps if your line goes dead
- Borrow another phone and call your network immediately, using a number from your invoice or its website.
- Phone your bank on the number on your card and ask for the account to be secured, explaining that you suspect a SIM swap.
- Change the passwords on your email and banking from a device that is not compromised.
- Open a SAPS case and keep the case number.
- Ask your network for written confirmation of what was done to your number and when, which is the evidence a bank dispute rests on.
What information to prepare
- Your mobile number and account number as they appear on your invoice.
- The identity document the account is registered against.
- The time your service stopped, and the time of any suspicious call or message.
- The number that contacted you, and screenshots of the messages.
- Any reference number from an earlier call, with the date.
What not to share
- One-time passwords or verification codes, including any code the caller says will arrive shortly.
- Your SIM serial or ICCID number, to a caller who contacted you.
- Your banking login details or card PIN, which no network needs.
- Remote access to your handset for a network to diagnose a fault.
- Copies of your ID to a WhatsApp number you have not confirmed on the operator’s own site.
If the issue is not resolved
Put the complaint to your network in writing and obtain a reference number, since ICASA will expect to see that the provider was approached first. If the provider does not resolve it, approach ICASA on 012 568 3000 or [email protected] with your reference and correspondence, after confirming your matter falls within its mandate. Where money was taken, pursue your bank in writing quoting your SAPS case number, and escalate to the National Financial Ombud if the bank’s own process is exhausted without resolution. No route guarantees recovery.

Frequently asked questions
What is the safest way to reach my network?
The short dialling code published by your operator, called from your own SIM, or the operator’s own app. Both keep you inside the network. Otherwise use the number on your invoice or the contact page on the operator’s domain, typed in yourself.
My phone suddenly has no signal. What should I do?
Treat a sudden, sustained loss of service as a possible SIM swap. Use another phone to call your network and your bank immediately, change your email and banking passwords from a clean device, and open a SAPS case.
What information should I prepare?
Your mobile and account number from your invoice, the ID the account is registered against, the time service stopped, the number that contacted you with screenshots, and any earlier reference number.
What should I do if I cannot get help?
Complain to the network in writing and keep the reference, then approach ICASA on 012 568 3000 or [email protected] once the provider has had its opportunity. Pursue any financial loss through your bank with your SAPS case number.
