A new SIM has to be RICA registered before it will work. Activation is done by the network that issued the SIM, and no other party can do it.
ContactDetails.co.za is an independent directory. We are not any of the companies listed here and cannot act on your behalf. Everything on this page is a routing aid so you reach the right official channel with the right information in hand.
Who actually handles this
Your mobile network. RICA is the law that requires every SIM in South Africa to be registered against an identified person at a physical address. Until that registration is complete and processed, the SIM will not carry calls or data, and no amount of restarting the phone changes that.
What to do, in order
- Register the SIM. This is done at a store of the network, or through the network’s own app or website where it offers that.
- Have your ID document and proof of address ready. RICA requires both, and a registration submitted without them will not complete.
- Insert the SIM and restart the phone once registration is confirmed.
- Allow time for the registration to process before deciding something is wrong. Activation is not always instant.
- If it still does not work after that, contact the network with the SIM’s serial number.
What to have ready before you make contact
- Your ID document.
- Proof of address, such as a utility bill or a bank statement in your name.
- The SIM serial number, which is the long number printed on the SIM card holder.
- The number you were allocated, if you were given one.

Who owns what on a South African connection
- The mobile network (Vodacom, MTN, Cell C, Telkom, Rain) owns the spectrum, the towers and your number. Anything to do with the SIM, the number, coverage or a mobile account is theirs.
- The fibre network operator owns the physical fibre in your street and the box on your wall. It installs and repairs the line, but its customer is your ISP, not you. It holds no record of you and will refer you back.
- Your ISP sells you the internet service, holds your account, bills you and owns the relationship. For a fibre connection, this is almost always the party you should be contacting.
- ICASA licenses and regulates the operators. It is a regulator, not a support desk, and it takes complaints only after the operator’s own process has been used.
Most wasted time on a connection problem comes from contacting the wrong one of these four. Working out which layer your problem sits in, before you dial, is worth more than any number on this page.
Common mistakes that cost time
- Restarting the phone repeatedly instead of checking whether RICA registration has completed. No amount of restarting activates an unregistered SIM.
- Arriving to register without proof of address. It is the document people most often forget, and registration cannot complete without it.
- Assuming activation is instant. Processing time is normal, and reporting a fault too early just adds a wasted call.
- Registering a SIM in your name for someone else. The number stays tied to you, including anything done with it.
The scam to watch for
Do not RICA a SIM in your name for somebody else. The registration ties that number to you, and a SIM registered in your name that is used for fraud leads investigators to you first. This is a common request from strangers offering a small payment, and it is never worth it.
If it is not resolved
ICASA is the Independent Communications Authority of South Africa, the regulator for licensed telecommunications operators. It handles complaints against operators, but only after you have given the operator a chance to resolve the matter first, and it will ask for the operator’s reference number.
Escalation works on evidence. Keep a short written log of every contact: the date, the channel you used, the name of the person you spoke to and the reference number you were given. Every formal complaints process asks for exactly that history, and having it ready is usually the difference between a fast resolution and starting over.

Frequently asked questions
Why will my new SIM not work?
The most common reason is that RICA registration has not completed. Until it does, the SIM cannot carry calls or data.
Can I RICA online?
Some networks offer online or in-app registration and others require a store visit. Check your own network’s official site rather than a third-party page, because the requirements are set per operator within the law.
Do I need to RICA again if I already have other SIMs?
Yes. RICA applies per SIM, not per person, so each new SIM is registered separately.
