From the wildlife-filled savannah of Kruger National Park to Durban's beaches and Cape Town's towering Table Mountain, South Africa has a seemingly-endless list of attractions for visitors. 

It's a big country, though, and while Wi-fi is readily available in the cities, it's not always free or particularly fast. Fortunately, staying connected with a local SIM card is easy and inexpensive, and data speeds can be surprisingly quick.

Here's what you need to know.​



COMPANIES

  • We recommend Vodacom or MTN for most travellers
  • If you're also visiting Swaziland, go for MTN

There are four cell service providers in South Africa, plus a small number of resellers. Vodacom and MTN have the best coverage, especially outside the cities, with Cell C and Telkom trailing behind.

LTE data is available with all providers if your phone supports the right frequencies.

I decided to pick up a Vodacom SIM, since the company boasted of having the fastest network in the country. My travelling companion bought one from MTN for comparison.

HOW

Both MTN and Vodacom have kiosks in some or all of South Africa's international airports. Vodacom makes life particularly easy for overseas visitors with its B4IGO service, letting you buy the SIM and call/text/data package ahead of time via Paypal or international credit card, and pick it up on arrival. Note, though, that you'll pay quite a lot more for the convenience.

For cheaper rates, buy your SIM at any of the other official stores -- you'll find several in the major cities. I bought my Vodacom SIM in Cape Town's central business district, while my companion bought her MTN version at the sprawling Gateway mall just outside Durban.​

In neither case did the staff seem particularly excited about their jobs, but it only took a few minutes to buy and activate the SIM and package. You'll need your passport, and potentially proof of where you're staying in the form of a booking confirmation. I wasn't asked for it, but my companion was.​

Note that many of the places displaying MTN or Vodacom logos don't sell SIMs, or can't register them to you. You'll have no problem topping up there, but for the initial purchase, look for official stores and certain supermarkets.​

COSTS

As long as you don't buy at the airport, staying connected is inexpensive in South Africa. I paid all of one rand (~7c) for the SIM, and 149 ZAR (~$11) for 1GB of data, valid for a month. I added an extra 20 ZAR for calls and texts, and was good to go.

With MTN, my companion paid 3.50 ZAR for the SIM, and 260 ZAR (~$20) for 2GB of data, plus a bonus 1GB, valid for a month. 

If you're a heavy data user, the data bonuses make MTN a cheaper option than Vodacom. For light to moderate use, there's little difference.

MTN is the only South African provider that roams in Swaziland. Your existing data, call and text packages don't work there, however, and you'll pay a relatively expensive 1 rand per megabyte for data.

 

Can't be bothered with the hassle of buying a local SIM in South Africa? KnowRoaming topped our international SIM card comparison.

The company's SIM cards, stickers and hotspots can be sent out ahead of time, so you'll hit the ground running in 200 countries, and save up to 85% on roaming fees while you're there. Unlike other companies, using WhatsApp for texts and calls anywhere in the world is absolutely free.

TOPPING UP

You'll see MTN and Vodacom logos in pretty much every convenience store window, plus supermarkets, gas stations and elsewhere. Reload vouchers come in a range of different values -- just pick and mix to make up the amount you need.

COVERAGE AND DATA SPEEDS

Coverage was generally good with both Vodacom and MTN, even halfway up Table Mountain and other out-of-the-way locations. I did notice a few occasions, though, when my phone reported full signal, but web pages would time out or take forever to load. Waiting a couple of minutes, or walking further down the street, always fixed the problem.

With both providers, 3G speeds were towards the high end of the range, as shown below. LTE speeds with Vodacom hovered around 30Mbps.

Roaming with MTN in Swaziland was as simple as adding extra credit (it can be done in both South Africa and Swaziland), then activating data roaming after arriving in the country. Coverage was good, both in Mbabane and Manzini, and in the countryside and national parks.

    Great information. I wish I had known how much cheaper it was to skip the airport. I probably still would have done the airport though as we got in late at night and I needed a phone early the next morning. I’m pretty new at traveling with a smart phone so your guides are great. Next time I go to Cape Town I will do it your way.
