Somewhere around the end of January the same headline landed in three of my WhatsApp groups inside about an hour, which is how you know a tech story has properly escaped the tech pages and gone out into the wild where actual people live. Data will no longer expire. That was the line, forwarded with the little celebratory emoji that South Africans reserve for the rare occasion when something in this country appears to move in our favour, and honestly I understood the reaction completely, because losing paid-for data is one of those small recurring humiliations we have all just decided to accept.
Then I read the regulations, and the good news got noticeably smaller.
Your data does not stop expiring. It expires later, once, and only if you bought the right kind of bundle. The cheapest bundles in the country, the ones that the people who most need this protection are actually buying, are excluded from the whole arrangement. And while everyone was forwarding that headline around, MTN and Vodacom were building a legal case to have the entire thing thrown out, which they filed two weeks ago.
The word that was never in the regulations
The instrument doing all this work is the End-User and Subscriber Service Charter Amendment Regulations, gazetted by ICASA on 23 January this year with a full twelve months of runway before it binds anyone, which means the date you actually care about is 23 January 2027 and not a day earlier. That runway exists because Vodacom, MTN, Telkom and Cell C have to go and rebuild the billing systems that currently decide the moment your bundle dies, and those systems are older and messier than any of them would like to admit publicly.
What the regulation says is that at the end of a bundle’s validity period, whatever you have not used gets rolled over at least once, automatically, at no cost, on the same terms as the bundle you originally bought, for as long as your number stays active. Your older bundles have to be consumed before your newer ones, so the networks can no longer quietly burn the fresh gigabyte you just bought while the one you paid for three weeks ago runs out the clock. You get to transfer unused bundles to someone else on the same network for free. And you carry on getting those depletion notifications at 50%, 80% and 100%.
Read that first phrase again though, because it is the real story that almost nobody reported on. At least once. Not indefinitely, permanently, or never. Your 30 day bundle becomes, at minimum, a 60 day bundle, and at the end of that second stretch the leftovers still evaporate exactly as they always have. There is no data savings account being opened in your name, no vault where every gigabyte you failed to use in 2027 quietly accumulates into a rainy day fund. The rule buys you one extra cycle and then the old rules resume.
What changes: a 30 day bundle you half-used becomes roughly a 60 day bundle. What does not change: data you buy and never touch still disappears eventually. The word doing all the heavy lifting in the coverage was “never,” and “never” appears nowhere in the actual document.
That gap between what people were told and what they are going to receive is going to produce a very specific kind of anger in about eighteen months, and it will be aimed at the networks rather than at the newsrooms that oversold it, which is a slightly unfair outcome but a completely predictable one.
You were never buying data, you were buying time
Here is the very important exclusion, which is buried where exclusions always are, right at the end when you’ve already stopped paying attention. Uncapped bundles are out. Free bundles are out. Promotional bundles are out. And any bundle with a validity period of seven days or less is out.
Vodacom will currently sell you a gigabyte for around R12 if you agree to consume it inside an hour. Telkom will do a daily gig at roughly R23, Cell C at about R25, Vodacom at about R29, and MTN has been running ten gigs a month for something in the region of R149. The gigabyte is identical in every one of those transactions. What you are paying for, and what the entire South African data market is actually built to sell you, is time, and the less time you buy the cheaper the data gets, which is why the cheapest data in this country is systematically sold to the people with the least ability to plan around it. It is the same logic that has quietly priced most South Africans out of flagship handsets, applied to airtime instead of hardware.
Now apply the regulation to that structure. The rollover obligation attaches to the long-validity bundles, which are the expensive ones. It does not attach to the short-validity bundles, which are the cheap ones. So ICASA has just added a cost to one side of the shelf and left the other side untouched.
Ten years inside a handset business that lived or died by its relationship with these operators taught me one thing about commercial teams that I have never once seen contradicted, which is that they do not fight a regulation head on when there is a perfectly good door standing open beside it. The door here is seven days wide. My honest expectation, and I will happily be wrong about this in public, is that between now and January 2027 the daily and weekly bundles get better, louder and pushed considerably harder through the apps and the USSD menus, while the 30 day bundles quietly stop improving at the same rate. Nobody will announce this. It will simply be what the promotional calendar starts doing.
And the outcome, if that happens, is genuinely shocking. A regulation written to stop poor people losing prepaid data would end up nudging more poor people onto seven day bundles that carry no rollover protection whatsoever. That is not an argument for scrapping the rule. It is an argument for watching what happens after it lands instead of declaring the match won at the gazette.
The quiet clause that matters more than the loud one
Strip the rollover headline out entirely and there is something better sitting underneath it that got almost no coverage at all, which is that out-of-bundle billing becomes opt-in.
Everyone reading this knows the feeling even if they have never spoke about it. Your bundle runs out somewhere around the 22nd and nothing on the phone changes. The video carries on playing, and you carry on scrolling in complete ignorance while your airtime is consumed at a multiple of the rate you were paying ninety seconds earlier. Then you go to make a call and there is nothing there. That mechanism and not the expiry, is behind most of the genuine horror stories South Africans tell about their networks, and it is the reason so many people keep a second SIM in a drawer out of pure defensive superstition.
Making it opt-in flips the default from silently expensive to safely stopped. Nothing happens unless you actively choose it. ICASA’s stated reason for tightening all of this is that operators had evaded the spirit of the 2018 and 2023 rules, and out-of-bundle billing is the cleanest illustration of exactly what it meant by that.
It is also, and I do not think this is a coincidence, one of the three provisions MTN has taken to court.
Four years of arguing, and now a courtroom
MTN served papers on 22 July asking the high court to review the regulations, set them aside and declare them invalid, with ICASA cited as first respondent. Vodacom filed its own application shortly afterwards targeting parts of the same instrument. MTN is going after three things specifically: the rollover obligation, the out-of-bundle opt-in and the unrestricted transfer requirement. Its legal argument is that ICASA acted beyond its powers. Its commercial argument is that the rules will reduce competition and push prices up by removing the operators’ ability to sell cheaper bundles that trade rollover and transfer rights away, and that the field is uneven because mobile virtual network operators are not covered by any of it. Vodacom’s position is gentler, essentially that chunks of the regulation are ambiguous and difficult to implement, while stressing that it supports consumer protection in principle.
The easy move is to wave all of that away as two very large companies defending a revenue line, and there is unmistakably some of that in the mix. But the strongest version of their case deserves to be taken seriously, partly because Vodacom has been making it consistently since 2022, back when ICASA wanted a six month rollover and Vodacom warned it would end up penalising poorer customers by killing the discounted short-validity bundles they depend on. That argument is internally coherent. Expiry is precisely what makes a cheap bundle cheap, so if you remove expiry either the price goes up or the discount goes away, and the first person to feel that is somebody buying R12 of data at a spaza counter rather than somebody on a R899 contract who has never once checked their balance.
Where it gets much harder to defend is the timing. This fight has run for more than four years. ICASA proposed the hard version in 2022, softened it to a once-off rollover in 2024 under industry pressure, and both operators pushed unsuccessfully for a formal regulatory impact assessment before the rules were finalised. There was a long, well-lit window in which MTN and Vodacom could have produced their own modelling showing exactly how consumers would be harmed, and put it on the public record where a regulator would have found it genuinely difficult to ignore. They had the data. They have the best data on prepaid buying behaviour in the country. Choosing litigation over evidence, after four years of being asked for the evidence, tells you something about which argument they thought was stronger.
What to do while the lawyers get paid
Nothing changes today, and the court challenge means 23 January 2027 is now a date to hold loosely rather than to plan around. Some provisions may survive while others fall. Implementation may slip while the matter runs. Regulations that reach a gazette are not the same thing as regulations that reach your account, and there is now a courtroom sitting between the two.
| If you | What this actually means for you |
|---|---|
| Buy 30 day prepaid bundles | You are the clearest winner, assuming the rules survive. Your unused portion carries into a second cycle from January 2027. |
| Live on daily and weekly bundles | Excluded from rollover entirely. Watch for these being pushed a lot harder between now and the deadline. |
| Are on contract with an included allocation | The out-of-bundle opt-in is the change that will show up on your statement, not the rollover. |
| Buy uncapped or promotional bundles | Explicitly carved out. Nothing changes at all. |
In the meantime the genuinely useful thing to do is deeply unglamorous. Go and find out what your network currently charges you out of bundle, because that number is the entire reason this regulation exists and I would bet good money you have never once looked it up. Then be honest about whether the bundle you buy every month is actually matched to what you use, because rollover only rewards you for data you were already wasting, and the better fix for wasting data has always been to stop buying more of it than you need.
The forwarded headline was not wrong to be hopeful. It was just early, and considerably more optimistic than the document it was describing. Somewhere between now and January 2027 a judge gets to decide how much of it survives, and I would rather we all went into that with the actual facts than with the emoji.
