Yes. Every big South African network raises its contract prices once a year, and the increase applies to people already on a contract, not just to new customers. What goes up is the plan part of your monthly price. In the last round all four networks left the handset instalment where it was.
We read each network's announcement of its last annual increase, as reported, and the Consumer Protection Act (CPA) regulations that govern price changes. This is general information, not legal advice. Check your own contract, which is where the rule that applies to you is written.
What each network did in the last round
| Network | When | How much | Handset instalment |
|---|---|---|---|
| Cell C | From 1 December 2025 | About 8% on post-paid subscriptions, about 4% on the total bill | Unchanged, as were out-of-bundle rates |
| MTN | From February 2026 | 9.7% on subscription fees on average, 5.4% on the total bill | Excluded |
| Vodacom | February, March or April 2026, by sign-up date | About 5% | Device fees unchanged |
| Telkom | From 1 April 2026 | A blended 6.5% on post-paid subscription fees | Excluded |
Some examples of what that looks like:
- Vodacom: RED VIP 12GB went from R 1 675 to R 1 758.99 a month.
- MTN: Yellow Plans Elite went from R 649 to R 695, and Sky Premium Iron from R 799 to R 849.
- Cell C: its letter to customers put Elevate 2+ up from R 229 to R 249.
When it applies depends on when you signed. Vodacom's 2026 increase took effect on 1 February for contracts entered into before 31 October 2025, on 1 March for contracts from 1 November to 31 December 2025, and on 1 April for contracts from 1 January to 5 February 2026. So someone who signed a Black Friday deal in November 2025 had two months more at the old price than someone who signed in October. Telkom said its increase applied to new and existing customers regardless of contract status.
What the law allows
The CPA does not ban price increases in a contract. It controls how they are written.
- A clause that lets the network raise the price with no way out is presumed unfair. Regulation 44(3)(h) lists, as a term presumed unfair, one "allowing the supplier to increase the price agreed with the consumer when the agreement was concluded without giving the consumer the right to terminate the agreement".
- An indexation clause is allowed if it says how. Regulation 44(4)(b)(iii) excludes from that a price-indexation clause, "where lawful, but the method by which prices vary must be explicitly described". A clause that ties the increase to inflation or a stated percentage, and that you agreed to when you signed, is the kind the networks use.
- You can always cancel a fixed-term contract. Section 14 lets you cancel on 20 business days' notice in writing, with a reasonable cancellation penalty. See cancelling a contract early for what counts as reasonable.
The regulator has its own rules. The Independent Communications Authority of South Africa (ICASA) requires a network to notify it of a tariff change seven days before the change takes effect, under regulation 9 of its tariff regulations. ICASA fined MTN R5 million in 2019 under these rules. Vodacom says it gives its customers 20 working days' notice of a change.
What an increase adds to your contract
A contract's monthly price is the handset instalment plus the plan. Because the increase is on the plan only, the headline percentage overstates what happens to your bill.
Take the 256GB Galaxy S26 Ultra on Cell C's Elevate 2+ over 36 months: R 1 199 a month, of which R 229 is the plan fee and the rest pays for the phone. Over the contract that is R 43 164, at today's price. If the plan rises 8% at the start of year two and another 8% at the start of year three:
| Year | Plan fee | Monthly price | Extra that year |
|---|---|---|---|
| 1 | R 229.00 | R 1 199.00 | - |
| 2 | R 247.32 | R 1 217.32 | R 219.84 |
| 3 | R 267.11 | R 1 237.11 | R 457.27 |
That is about R 677 over the contract, under 2% of the total. The 8% rise is R 18.32 a month in year two, about 1.5% of the bill. On a cheap phone, where the plan is most of the price, the same percentage moves the bill more; on a SIM-only plan, it applies to all of it.
This is an illustration, not a forecast: the rise depends on your network, your plan and the year, and each network's increase in the last round was different. It is also why every total we show on Vulo is the price today times the number of months, with no increase assumed.
What to do
- Read the price-change clause before you sign. It says when the price can change and how it is worked out. If you can't find one, ask.
- Know your split. Ask what part of your monthly price is the handset and what part is the plan. The plan is the part that goes up.
- Watch for the notice. Networks tell customers before the change takes effect. Check the new amount on your next bill against it.
- Weigh it against cancelling. If the new price makes the contract poor value, work out the cancellation penalty first. Our switch-cost calculator adds up what you would still owe.
- Complain in writing if it looks wrong. Start with the network. If it is not resolved, you can complain to the National Consumer Commission. Keep your contract, the notice and your bills.
What to watch for
- The increase usually comes once a year, and the dates above suggest the next round from December 2026 to April 2027. Nothing about it has been announced as we write.
- A new customer's price is not the old one plus an increase. Cell C's letter put Elevate 2+ at R 249, but on 3 November 2026 the plan fee it showed to new customers was R 229, and its Black Friday SIM-only price is R 149.
- These figures are as reported. We read news reports of each network's announcement, not every customer letter. Your own notice is what applies.

Frequently asked questions
- Can a network increase my contract price during the contract?
- Yes, if the contract allows it, and the big four networks' contracts do. Each raised its contract prices in the last annual round: Cell C from 1 December 2025, MTN from February 2026, Vodacom from February to April 2026 depending on when you signed, and Telkom from 1 April 2026. The Consumer Protection Act regulations allow a price-indexation clause, but the way the price changes must be explicitly described.
- Does the handset part of my contract go up too?
- In the last round, no. MTN, Telkom and Cell C said the device instalment was excluded, and Vodacom said device fees were unchanged. The increase applies to the plan part of the monthly price, so it is a smaller share of the total bill on an expensive phone.
- How much did the networks raise prices by?
- Vodacom by about 5% (RED VIP 12GB from R 1 675 to R 1 758.99), MTN by 9.7% on subscription fees on average, or 5.4% on the total bill, Telkom by a blended 6.5% on post-paid subscription fees, and Cell C by 8% on average on post-paid subscriptions, or 4% on the total bill.
- Can I cancel my contract if the price goes up?
- You can always cancel a fixed-term contract under section 14 of the Consumer Protection Act, with 20 business days' written notice, but the network may charge a reasonable cancellation penalty. The regulations presume a clause unfair if it lets the supplier raise the agreed price without giving the consumer the right to terminate, while allowing a lawful indexation clause that explicitly describes how prices vary.
- How much does an annual increase add to a contract?
- Less than the headline percentage suggests, because the handset part is fixed. On a Cell C Galaxy S26 Ultra deal at R 1 199 a month over 36 months, of which R 229 is the plan fee, an 8% rise on the plan in each of years two and three adds about R 677 over the contract, under 2% of the R 43 164 total.
