Staying connected in South Africa is easy and cheap. The country has good 4G and 5G coverage in the cities and along the main routes, and the simplest way to get online is an eSIM, which you can buy and activate before you even leave home. Two providers stand out, and we recommend both: Airalo and Ubigi. Below is how to choose, and how the two compare.
eSIM or local SIM?
If your phone supports eSIM (most recent iPhones and Android flagships do), it’s the most convenient choice: buy a data plan online, install it by scanning a QR code, and you’re connected the second you land, with no queues and no swapping out your home SIM.
A physical local SIM (Vodacom or MTN have the best coverage) can be cheaper for long stays and gives you a local number, but you’ll need your passport to register it under the RICA law, plus a stop at an airport kiosk or store.
Quick pick: for a 1–3 week trip, an eSIM data plan is the easiest. For a month or more, a local Vodacom or MTN SIM can work out cheaper.
Our two picks: Airalo and Ubigi
Both are travel eSIM specialists, both are data-only (you stay reachable on WhatsApp and the like rather than a local voice number), and both activate automatically when you first connect on arrival. The difference is in the network they use, the way the plans are shaped, and what each does best.
Airalo is the world’s biggest travel-eSIM store, with over 30 million users and an app in dozens of languages. Its South Africa data plans run on the Cell C network, with a long ladder of tiers, from 1 GB for three days at about $4 up to 50 GB for thirty days at around $49, so you can match the plan closely to your trip. It also sells an Unlimited line on the Vodacom network, from roughly $20.50 for three days.
Ubigi runs on the MTN network, one of South Africa’s two strongest, which is its main advantage for coverage outside the cities. It leans towards strong value per gigabyte and bigger or open-ended allowances: 1 GB for thirty days at about $6, 50 GB for thirty days at around $55, and an Unlimited plan at about $36 for seven days or $88 for thirty. A Ubigi plan stays valid for up to six months before you activate it, and it offers recurring monthly plans, handy for longer or repeat trips.

Which should you choose?
For most one- to three-week trips, Airalo is the easy default: the fine-grained tiers let you buy close to what you’ll actually use, the app is effortless, and the price is keen. Reach for Ubigi if coverage outside the cities matters to you and you want the MTN network, if you want a large or genuinely unlimited allowance, or if you’re travelling longer and would rather a plan that holds its validity for months or renews monthly. Many travellers happily use either, and you can install both and keep one in reserve.
Coverage: cities vs reserves
Expect fast, reliable data in Cape Town, Johannesburg, Durban and along the Garden Route on any of these. In the Kruger and the remote reserves, coverage is patchy on every network, fine around the camps and often absent on game drives. The network does matter out in the country: MTN and Vodacom generally reach further than Cell C, so Ubigi’s MTN plans, and Airalo’s Vodacom-based Unlimited, tend to hold up better in rural and bush areas. Wherever you are, treat the reserves as a chance to switch off, and download your maps and bookings for offline use beforehand.
Before you leave
- Check your phone is eSIM-compatible and network-unlocked.
- Buy your eSIM data plan in advance and keep the QR code or the app handy.
- Install the eSIM before you fly, then switch it on when you land (it activates on first connection).
- Download offline Google Maps and your booking confirmations.
- Note the local emergency number: 112 from a mobile.
