Best SIM Only Deals in South Africa: Which One Fits You

The best SIM only deals in South Africa right now start at R129 a month for 20GB, and top out at R399 for 200GB plus another 200GB of Night Owl data. That's the whole range on vShopper today. The hard part is picking the one that matches how you actually use your phone, because the cheapest deal is only cheap if you don't blow through it by the 14th.

TL;DR: Light user who lives on Wi-Fi? The 10GB + 10GB deal at R129 is plenty. Commuter who streams on the taxi? Go 60GB + 40GB at R229. Your phone is your home internet? Look at 100GB + 100GB at R299 or the R399 200GB bundle. All of them run on 24-month terms, and none of them come with a phone attached, which is the point.

Why SIM only is the smart move if your phone still works

Here's the opinion we'll stand behind: if your current phone still does its job, a new handset contract is usually the wrong move financially. That "free upgrade" isn't free. You pay for the phone inside the monthly fee, spread over 24 or 36 months.

A SIM only plan strips the phone out of the bill. You pay for data and nothing else. Keep the phone you've already paid off and the saving lands in your pocket every single month.

(Yes, even if the screen protector is now doing more structural work than the screen. Cracked glass isn't a reason to sign for three years. A repair is.)

We covered the full cost comparison in SIM-only vs contract: the real cost. This post is the next step: which SIM only deal to actually buy.

What does "Night Owl" data actually mean?

Half of every bundle above is Night Owl data. It only works in the early hours, roughly midnight to 7am. So treat it as a bonus for big overnight jobs: app updates, phone backups, downloading a whole series before the week starts.

Don't count it toward your daytime budget. If you need 40GB during waking hours, buy a bundle with 40GB of Anytime data, then enjoy the Night Owl half as extra.

Our explainer on Anytime, once-off and Top-Up data goes deeper if the jargon still feels like a pop quiz.

How much data do you actually use? Check before you pick

Most people guess. Most people guess wrong, usually by a lot.

Open Settings, then Mobile Data (Android) or Mobile Service (iPhone), and look at last month's total. That number is your starting point. Add about 20% because usage only ever creeps upward, never down.

• Under 15GB a month: you live on Wi-Fi at home and work. R129 covers you.
• 15GB to 40GB: WhatsApp voice notes, some YouTube, maps every day. The R179 deal fits.
• 40GB to 60GB: you stream on the commute or hotspot your laptop a few times a week. R229 is the sweet spot.
• 60GB to 100GB: you work off your phone's hotspot. R299.
• More than 100GB: your phone is the household router. R399, or have a look at proper home internet instead.

The sweet spot: why the R229 deal is our pick for most people

The 60GB + 40GB bundle at R229 gives you 60GB of Anytime data. That's 20GB more daytime data than the R179 deal, plus three 5GB Video Tickets for streaming and a promotional My Gig 20 on top.

It's R50 more than the R179 deal. For anyone who's ever bought an emergency data bundle on the 23rd of the month, R50 is cheaper than the panic.

When not to spend more

If last month's usage was 12GB, don't buy the 100GB deal "just in case". You'll pay R170 a month extra for data that expires unused. Over a 24-month term that's R4,080 for peace of mind you didn't need.

Start smaller. If you run out, you can buy a top-up. If you keep running out, upgrade the plan. Going up is easy. Paying for air for two years is the expensive mistake.

If you're using 200GB on your phone, look at home internet

The R399 bundle is great value per gig. But if the whole family is streaming off your hotspot, a dedicated router does the job better: no battery drain, more devices connected, and your phone stops running hot in your pocket.

vShopper's Home Internet range covers fibre and 5G routers from R429 a month. Worth a look before you commit to two years of phone-as-router.

What you need to sign up for a SIM only deal

A SIM only plan is still a 24-month agreement, so expect the same basic checks as any contract: your SA ID, proof of address, and recent bank statements. Self-employed applicants need to show income of R3,500 or more a month. Every SIM also has to be RICA-registered by law, which ICASA oversees. A 24-month SIM only plan is also a credit agreement under South Africa's National Credit Act, which the National Credit Regulator enforces, hence the affordability checks.

You can keep your existing number too. Porting moves it to the new SIM, so nobody has to update a contact.

Frequently asked questions

What is the cheapest SIM only deal on vShopper?
The 10GB + 10GB Data Top-Up at R129 a month on a 24-month term.

Is Night Owl data worth anything?
Yes, for overnight downloads, backups and updates. Just don't count it as daytime data.

Can I keep my number on a SIM only deal?
Yes. Ask for your number to be ported when you sign up.

Can I upgrade to a bigger bundle later?
Upgrading to a bigger plan mid-term is usually straightforward. Dropping down is harder, so start with what you use now.

Do I need a credit check for SIM only?
Yes. A 24-month SIM only plan is a credit agreement, so the network runs the usual affordability checks.

Will my current phone work with a new SIM?
If it's unlocked and supports the network, yes. Most phones bought in South Africa in the last few years are fine.

Your phone works. Your bill doesn't have to keep paying for it twice. Pick the bundle that matches last month's usage, add a bit of breathing room, and browse the full range on the SIM Only Deals page.
