Before you start

A valid passport — the accepted identity document for a foreigner under RICA
Proof of a South African address under three months old, or an affidavit or host letter
An unlocked handset, eSIM-capable if you want to land connected
R100-R400 for the SIM and a first data bundle

Step-by-step

1
Land connected with a travel eSIM
Buy an eSIM from a provider such as Airalo or Holafly before you fly and activate it on arrival at King Shaka International — no RICA, no queue, working data immediately. South African plans run from roughly US$4 for a few gigabytes to around US$20-25 for a month. It is a bridge for the first days while you organise an address, and a useful fallback afterwards when your main network has a problem.

2
Buy a prepaid SIM and complete RICA
Starter SIMs are sold at King Shaka, at carrier stores in Gateway and the Pavilion, and in every Checkers, Pick n Pay and Woolworths for a few rand. The SIM carries no traffic until RICA is complete: show your passport and proof of address in store, or self-register in the carrier app by scanning your passport and recording a short verification video. Activation takes minutes to about 24 hours. Confirm it is live before leaving the counter, because an unregistered SIM simply never connects and offers no explanation.

Choose the network for the coast you actually use
Vodacom and MTN are the safe defaults across the coastal corridor from the South Coast up through Ballito, and hold up better inland towards the Midlands and the Drakensberg. Cell C and Telkom undercut them on price and are fine in Umhlanga and the Berea but thin out quickly on the coastal roads and in the valleys. Rain sells contract-free data-only SIMs that work well as a second home connection where fibre has not reached.

Load airtime, then convert it into a bundle
Top up at any till, ATM or in the carrier app, then buy a data bundle before you use data — out-of-bundle rates are punishing and empty a balance in an afternoon. Buy by USSD (*135*2# on Vodacom, *136*2# on MTN) or in the app, at roughly R85 for 1GB, R150 for 10GB and R350 for 50GB a month. ICASA's end-user rules require operators to roll most unused bundle data over, so the larger bundle is now the sensible buy. WhatsApp is how landlords, tradespeople, schools and neighbourhood watches all communicate here.

5
Get home fibre, and buy a UPS at the same time
Check which network is in your street — Openserve, Vumatel, Frogfoot and MetroFibre all operate along the corridor — then choose an ISP that resells on it: Afrihost, Webafrica, Cool Ideas, RSAWEB and Vox compete over the same lines. Uncapped home fibre runs roughly R400-R900 a month. In a complex or estate, ask the body corporate which operator holds wayleave, because building-level exclusivity is normal. Buy a small UPS for the fibre terminal and router at the same time: summer storms and local faults take this coast's power down often enough that it pays for itself in a season.

Documents you’ll need

Valid passport for RICA identity verification
Proof of a South African address under three months old
Affidavit or host letter if no bill is in your name
An unlocked phone, eSIM-capable if possible
Landlord or body corporate consent for a fibre installation

Things most newcomers don’t know

RICA requires proof of a South African address, not just identity — so you hit the same document wall for a phone number as for a bank account, on day one instead of week three.

The intuitive order is SIM, then bank, then lease, and address proof breaks it at the first step. A letter from your guesthouse or short-let host, or a free affidavit from any SAPS station, satisfies it. Asking for that letter while you are still checked in on the north coast is far easier than chasing it by email after you have moved.

Never browse on raw airtime. Out-of-bundle data rates are an order of magnitude above bundle rates, and a phone falls back onto them silently when a bundle runs out.

It is the single most common way newcomers lose money on South African telecoms, with no warning until the balance is gone. Buy the bundle by USSD before using data, turn on the carrier's out-of-bundle block in the app, and buy larger bundles now that ICASA's rules require most unused data to roll over.

In a Durban complex, estate or apartment block, which fibre network you may use is decided by the body corporate's wayleave agreements. Building-level exclusivity is entirely normal.

The ISP market looks competitive from the outside and can be a monopoly of one at your front door. Ask the letting agent which operator serves the building and what speeds are available at that specific unit before you sign — 'which ISPs operate in Durban' is a different question with a far happier and completely irrelevant answer.

Buy the router UPS even though load shedding stopped. This coast's outages come from summer storms, flood damage to infrastructure and local faults rather than from national generation — and the 2022 floods showed how long some of those repairs take.

People retire their inverters the moment national load shedding ends and then lose a working day to a substation fault after a downpour. A R1,500 UPS on the fibre terminal and router covers the common case, mobile towers usually stay up long enough to hotspot, and keeping a charged power bank is a cheap habit on a coast where storms are seasonal and reliable.

Common mistakes to avoid

Buying a SIM and not completing RICA, or assuming the airport vendor did it — an unregistered SIM never connects and gives no useful error.
Browsing before buying a data bundle and being charged out-of-bundle rates that empty an airtime balance in an afternoon.
Signing a lease in a complex without asking which fibre operator holds wayleave, then finding the ISP you wanted cannot serve the building.
Choosing Telkom or Cell C on price and then losing coverage on the coastal roads and inland to the Midlands.
Retiring the backup power the moment load shedding ended — this coast's outages are weather- and fault-driven, and they did not stop.
