ICASA wants a five-SIM cap per network: what it means

ICASA has proposed a limit of five SIM cards per person on each mobile network, but nothing has changed for most South Africans yet. If you use one or two SIMs, you probably do not need to do anything now. If you manage several lines for family, work, routers or trackers, you should start counting what is registered in your name.

MyBroadband reported that Vodacom and MTN said they were carefully considering ICASA’s proposal. The summary does not say when any rule could start, how it would be enforced, or what exceptions might apply.

What happened and what has not changed yet

The key point is simple: this is a proposal, not a live rule you need to follow today. The proposal is a cap of five SIMs per network, not five SIMs across all networks combined.

If the rule goes ahead in that form, you could have up to five on Vodacom and up to five on MTN, for example. What we do not know yet is how ICASA would count inactive lines, eSIMs, data-only SIMs or business accounts.

Who is most likely to feel a five-SIM cap

Most people will never hit five SIMs on one network. The people at risk are the ones who use SIMs for more than just one phone number.

People who should pay attention

• Small business owners with separate numbers for sales, support or deliveries
• Families where one adult registers SIMs for children, parents or shared devices
• Home internet users with LTE or 5G router SIMs
• People with trackers and alarms that use their own SIMs
• Frequent prepaid buyers who keep spare SIMs for promos or bundle deals
• Travellers who rely on dual-SIM or eSIM setups

If that sounds like you, the real issue is not just how many SIMs you actively use. It is how many are still linked to your ID on each network.

What is still unclear about the proposal

This is where the practical problems start. The source summary confirms the proposal and the networks' response, but not the fine print.

That uncertainty matters. A five-SIM cap may sound easy on paper, but it could be messy if network records are wrong or if people have forgotten about old prepaid lines.

What you should do now if you have several SIMs

You do not need to cancel anything in a panic. You do need a clear list.

1. Count your SIMs by network. Make separate lists for Vodacom, MTN, Telkom, Cell C and Rain.
2. Add device SIMs. Check your router, tablet, smartwatch, car tracker, alarm and spare phones.
3. Check family lines. If a child or parent uses a SIM registered in your name, include it.
4. Stop collecting extra prepaid SIMs unless you need them. Spare lines could become a headache later.
5. Keep a simple record. Save the number, network and what each SIM is used for.

If you are buying a new line mainly to test signal, first read our guide on how to check mobile network coverage before buying a SIM. That can save you from stacking up extra SIMs you do not really need.

Worked example: one household can hit the cap faster than you think

Example: One person has these Vodacom SIMs registered in their name:

• Main phone SIM
• Backup prepaid SIM
• Home LTE router SIM
• Child's phone SIM
• Vehicle tracker SIM
• Tablet data SIM

That is six Vodacom SIMs. If ICASA's proposal becomes a hard five-SIM limit with no exception, that person may need to move one line to another family member's name or to another network.

If the same person also has three MTN SIMs, that would not automatically break the proposed rule. The cap is per network, not across all networks together.

What this means if you are shopping for a contract or bundled SIM

This matters most if you keep adding low-cost lines on one network because a device deal includes a SIM. The deal may still be good, but the extra line could count against you if the proposal becomes a rule.

For example, the Xiaomi Redmi Note 15 starts from R4,999, and we track Vodacom deals at R349/month over 36 months with 1GB data or R399/month over 24 months with 1GB data. The Samsung Galaxy A56 starts from R7,194, with Telkom deals at R429/month over 36 months with 2GB data or R549/month over 24 months with 2GB data.

If you want to compare the phone itself before taking a contract, see the Xiaomi Redmi Note 15 specs and prices or Samsung Galaxy A56 specs and prices. If you are comparing contracts, our latest phone contract deals page is the better place to start.

Travellers should also keep an eye on this. A per-network cap may not stop dual-SIM use, but it could affect how many spare local lines you keep. Our guide to eSIM, roaming and dual-SIM tips for 2026 travellers covers the basics.

Should ordinary users worry right now?

No. For most people, this is a watch-and-check story, not an emergency.

If you use one SIM, or two across different networks, you are unlikely to feel any immediate effect. The bigger risk is for people who have lost track of old prepaid lines or who run several connected devices under one ID.

My view is that a cap could make sense only if ICASA and the networks give you a clear way to see every SIM linked to your name and fix mistakes. Without that, the rule could hit organised families and small businesses harder than the people it is meant to stop.

This is also the kind of regulation that can sound technical and then affect everyday choices later. We have seen that before with ICASA’s delayed data rules and the network-sharing rewrite.
