South Africa is well covered where you will spend most of your time and deliberately uncovered where you are going to look at animals. It is also the one country on this list where the power supply has, at times, affected whether the mobile network works — which is worth understanding before you depend on it.
Cities and the N-roads, then the reserves
Cape Town, Johannesburg, Pretoria and Durban are densely covered, and the N1, N2 and N3 highways hold a signal for effectively their full length. The Garden Route between Cape Town and Port Elizabeth is well served throughout, which is convenient because it is the single most driven tourist route in the country.
The Winelands, the Cape Peninsula and the Drakensberg resort areas are fine. The Karoo is sparse between towns and the distances are long.
Game reserves are the specific case. Kruger has coverage at the main camps and gates and much less of it out on the roads between them, and the private reserves vary from good Wi-Fi at the lodge to nothing at all by design. Many lodges actively prefer guests not to be connected on a drive, and that is a reasonable position rather than a shortfall.

Live prices in GBP, updated from our network partners. 6 plans currently available for South Africa. Validity counts from the moment the eSIM first connects to a network in South Africa, not from when you buy — so installing days before you fly costs you nothing.
£2.49 is the entry price rather than the best value. At £2.49 per gigabyte it is the most expensive data on the list; the 20 GB plan at £27.49 is £1.37 per gigabyte. If there is any realistic chance you will use more than 1 GB, the larger plan costs less than buying the small one twice.
Roaming, and whether you need this at all
South Africa is well outside any European roaming regime and standard international roaming is expensive. One roaming partner network is available to us here — the operator with the widest national footprint — so the plan's coverage is that network's coverage.
Load-shedding and what it does to towers
South Africa has experienced scheduled rolling power cuts, known locally as load-shedding, and when they occur they can affect mobile base stations as well as houses. Networks have invested heavily in backup power for exactly this reason and the situation has improved considerably, but during extended outages some areas have seen degraded mobile service.
The practical response is the same one locals take: keep the phone charged when you have power rather than when you need it, carry a power bank, and have offline maps for the day's route. None of this is specific to a travel eSIM — a local SIM sits on the same towers.
Separately, ride-hailing is widely used in the South African cities and is a common reason visitors want data from the moment they land.
The networks you actually connect to
In South Africa our plans roam onto Vodacom (5G). That is worth stating plainly because it is the thing that determines your experience: a travel eSIM does not have its own masts, so your signal is whatever those operators have built, and 5G is available where they have deployed it and your handset supports it.
It also means no provider can sell you better coverage in South Africa than the local networks have. Where there is a gap, it is a gap for everyone — local customers included.
Before you buy
Check the handset takes an eSIM and is not carrier-locked. Dial *#06# and look for an EID alongside the IMEI — no EID means no eSIM hardware whatever the model name suggests, and a locked phone will install the profile and then refuse to register. The device compatibility guide lists what works.
Then install before you fly, while you still have reliable Wi-Fi. Setup by brand: iPhone or Android. If it will not connect after you land, this works through the causes in order.
