If you're looking for an affordable way to use your cellphone when travelling in South Africa, you can get a CellSA eSIM from only US$4.50 (approximately R81) for 7 days usage.

To get a CellSA eSIM, you'll need to have an eSIM-compatible device such as the iPhone 11, Galaxy S20, Pixel 3 or later devices. You can then order your CellSA eSIM through the Airalo app with instant delivery direct to your phone. There's no need to queue at the airport or to register the CellSA eSIM with your ID, saving you lots of time.

Once you've ordered your CellSA eSIM, it will only activate when your cellphone actually connects to a supported network in South Africa. This means the validity period will only begin when you actually land in South Africa and turn your cellphone on.

Your CellSA eSIM works with the dual-SIM function on most modern smartphones. This means you can use your regular SIM card alongside the CellSA eSIM (e.g. to receive incoming phone calls and text messages on your normal phone number).

Alternatives to CellSA

The main disadvantage of CellSA is the fact you're getting a data-only service on the eSIM. You will not get a local phone number in South Africa when you're using the CellSA eSIM in your phone.

If you'd like to call or text whilst you're travelling in South Africa, you'll need to use your normal SIM card instead (on which international roaming fees may apply). Alternatively, you can side-step these charges by making your calls through WhatsApp or other similar apps.

If you're looking for a more fully featured SIM card with a local phone number in South Africa (starting with +27), you could consider getting a regular prepaid SIM card upon arrival instead. This will involve some additional hassle (e.g. queuing up at the airport to get your SIM card, a registration process for the SIM card, etc) but it can be preferable and better suited for longer-term use in South Africa.

CellSA Coverage

If you're using a CellSA eSIM, you'll have access to 4G mobile coverage in South Africa. This is provided by the following partner networks:

Coverage Provider	Network Type	Coverage Area
Vodacom	4G LTE	South Africa

There's no international roaming available on a CellSA eSIM. Therefore, you won't be able to use it outside of South Africa. If you're planning to visit multiple countries on your trip, you may need to get a separate eSIM for the other countries you visit.

Other Airalo eSIMs

Airalo's CellSA eSIM can only be used in South Africa.

If you're planning to visit multiple countries on your trip, you could consider getting a Discover or Hello Africa eSIM. These eSIM plans will work in South Africa, as well as a number of other countries.

However, it adds the ability for you to make and recieve phone calls and SMS text messages on your eSIM. You'll be assigned a +43 phone number (based in Austria) to use for calling and texting.
