What you can buy at OR Tambo
OR Tambo International Airport (JNB) is South Africa's busiest gateway, and the arrivals level plus the public retail areas are where you will find mobile operator shops and kiosks selling prepaid SIM cards. You will typically see the well-known South African networks represented, along with resellers offering starter bundles aimed at visitors.
Two things are worth knowing before you join a queue:
- Registration is mandatory. South African law requires SIM cards to be registered (RICA) in the name of the user, which means presenting your passport and often a proof of address or local contact detail. This is normal and applies to every operator.
- Airport pricing is convenience pricing. A card bought at the airport can cost more than the same starter pack bought in a city centre shop, and the bundle that comes loaded on it may be smaller or shorter-lived than what you would choose yourself.
If your flight lands late at night, check opening hours before you rely on a kiosk being open.
Where the kiosks are
Airport layouts change, so use this as a map of what to look for rather than a fixed list:
| Location | What you will usually find |
|---|---|
| Arrivals hall, after baggage reclaim | Operator kiosks and small shops selling prepaid starter packs |
| Public retail area / terminal concourse | Full operator stores and electronics retailers |
| Departures, before security | Smaller convenience outlets, limited SIM stock |
If you cannot find a kiosk, ask at the information desk — staff are used to the question and will point you to whichever outlet is currently trading.
What it costs
We are not going to quote a price here, because airport SIM pricing in South Africa moves with promotions, bundle sizes and exchange rates, and a number printed today can be wrong by the time you land. What you can reasonably expect:
- A prepaid starter pack with a small data bundle included.
- Optional top-ups bought separately, either at the same counter or later via an app or voucher.
- A higher effective price per gigabyte than a city-centre purchase.
Budget for the convenience, and decide in advance whether that trade is worth it to you.
Airport SIM vs eSIM: a quick decision
| Your situation | Airport SIM card | eSIM from baobabsim.com |
|---|---|---|
| You land late and want to be online immediately | Depends on kiosk opening hours | Activates on landing, no queue |
| You want a local South African phone number | Yes, this is the main reason to buy one | Data-focused; check the plan record for what is included |
| You are staying a few days | Works, but you may overpay for the bundle | Usually the simpler choice for short trips |
| You are staying weeks or months | Local prepaid can be cheaper long term | Fine for the trip; a local contract may suit residents better |
| You want to keep your home number active for calls | Possible with dual SIM, but fiddly | Possible with dual SIM, and no shop visit |
A useful rule: buy an eSIM for the trip, and only buy a local SIM if you specifically need a South African number — for example to receive local calls or register for a service that requires one.
Before you buy anything
- Check your phone is compatible with eSIM if you are going that route. Our phone compatibility page lists the models that work.
- Check your phone is unlocked if you plan to use a local physical SIM.
- Have your passport ready for RICA registration.
- Know your data needs. A week of maps, messaging and the occasional upload is a very different bundle from streaming video every evening.
Setting up an eSIM for South Africa
If you choose the eSIM route, the sequence is short:
- Buy the South Africa eSIM in the South Africa store on baobabsim.com before you travel.
- Install it while you still have reliable home wi-fi — our installation guide walks through it step by step.
- Leave it switched off until you land, then turn it on and follow the activation guide.
- If anything does not connect, the troubleshooting guide covers the usual fixes.
Everything you need sits in the help centre, including order lookup if you have bought before and want to check an existing order.
If you do buy at the airport
- Ask the assistant to confirm the bundle size, validity period and what happens when it runs out.
- Ask whether the top-up can be done from the operator's app, so you are not hunting for a shop later.
- Keep the SIM packaging until you have confirmed it works.
- Test data before you leave the terminal — it is much easier to sort out a problem at the counter than from a taxi.
A note on coverage
No SIM or eSIM can promise a specific speed or signal at a specific address. Coverage depends on the network, the building and the moment. What we can tell you is what each plan includes — the product page in the store is the record to check, and it is the only place we state plan facts.
