Prepaid or Contract: What Pays Off in 2026 for Whom?

My neighbour has been buying her prepaid cards at the supermarket checkout for what feels like fifteen years now. Scratch off the code, type it in, done. Why does she do it? "That way I stay in control." That sentence has stuck with her ever since her son racked up a €340 bill with his first mobile plan back in 2011. Understandable. But does the reasoning behind the prepaid or contract question still hold up in 2026?

Short answer: only half as much as it used to.

The long answer takes a few paragraphs. Prepaid and contract plans have converged so much in recent years that the old rule of thumb – contract equals cost trap, prepaid equals safe – has developed some serious cracks. Time for an honest reckoning, while the carnival parades wind their way through the streets outside.

What still speaks for prepaid in 2026

Prepaid means you pay upfront, not afterwards. No credit, no cost. Full stop. That still makes prepaid the first choice for kids' phones, for the spare device in the drawer, and for anyone who, on principle, doesn't want a monthly direct debit. There's also an advantage rarely mentioned: no credit check is carried out for a prepaid SIM. Anyone who has just moved from abroad or has a patchy credit history gets a plan here without any fuss.

It's not expensive either. Lidl Connect gives you 5 GB for €4.99, Penny Mobil offers 5 GB for €5.99, and Aldi Talk starts at €6.99. If you mainly want to be reachable and check messages on the go now and then, this works perfectly fine.

And yet: the control advantage has shrunk. Third-party lock on request, cost caps for EU roaming, data usage warnings – much of what prepaid used to protect against is now defused by law. My neighbour's €340 bill would barely be possible today.

Why contracts have lost their sting

The most important point first: since December 2021, no mobile plan is allowed to quietly renew for another year anymore. After the minimum term, you can cancel on a monthly basis, with a one-month notice period. The notorious 24-month ball and chain therefore only exists for the first term – after that, you're almost as flexible as with a prepaid card. We've summarised what's changed recently around contract terms, eSIM, and more mobile plans 2026 here.

Then there's the price. Postpaid discounters have been undercutting each other for years: WinSIM from €4.99 for 3 GB, Blau with 8 GB for €7.99, 1&1 with 10 GB for €9.99. Calculated per gigabyte, a cheap plan today is almost always cheaper than the comparable prepaid option – especially because promotional offers happen almost exclusively in the plan segment. We've crunched the numbers on what's really worth it in this price range in the check of unlimited-calls plans under €10 guide.

Honestly, the biggest difference today is psychological: the contract keeps running even if you're not paying attention. Prepaid forces you to stay on top of it. Depending on your personality, that's either an advantage or an annoyance.

The side-by-side comparison

Criterion	Prepaid	Contract (Postpaid)
Cost control	Complete – nothing happens without credit	Good thanks to legal caps, but the direct debit keeps running
Price per gigabyte	Usually a bit more expensive	Usually cheaper, especially with promotions
Credit check	No	Yes
Flexibility	Can be paused at any time, no cancellation hassle	Only cancellable monthly after the minimum term
Effort	Remember to top up (or set up auto top-up)	Runs by itself – even if you've long forgotten about it
Phone number	Porting possible, but often more cumbersome	Porting is straightforward

Bottom line: no knockout win for either side. It depends on how much you use and how much you enjoy dealing with it.

The middle ground: contracts with no minimum term

A third option has established itself between these two worlds, and it gets surprisingly little attention: flex plans. These are perfectly normal contracts – just without a minimum term. You get contract convenience (automatic direct debit, easy number porting, full plan selection) while still being able to cancel every month.

An example from our comparison: Lycamobile offers its Global Connect plans on the O2 network both with a 24-month term and as a flexible option. The M plan with 25 GB costs €4.50 a month as part of the promotion. But watch out, the catch is in the fine print: with the fixed-term option, the promotional price applies for six months, while with the flexible option it only applies for the first month – after that, the regular price kicks in. Flexibility comes at a cost. If you're sure the plan is right for you, the fixed-term option works out cheaper; if you want to try it out first, go with the flexible option and keep an eye on the price jump.

The annual bill: an example with real numbers

Let's get concrete. Say you use around 5 GB a month, make occasional calls, and just want some peace of mind. With Lidl Connect you pay €4.99 every four weeks – watch out for this small catch: prepaid packages almost always run for 28 days, not a calendar month. That works out to 13 billing periods a year instead of 12, so around €64.87 a year. A contract discounter like WinSIM, with a comparable package billed in real calendar months, comes to about €60 a year – often with more data allowance on top.

A five-euro difference per year. Sounds like nothing, and honestly, at this usage level it barely matters. The gap only becomes noticeable with bigger packages, where contract promotions offer 25 or 50 GB at prices you'd only get a fraction of on the prepaid shelf. Still, you should know about the 28-day trap – it's the reason prepaid looks cheaper on the price tag than it actually is over a full year.

So what does this mean for you?

Three rules of thumb that still hold true in 2026:

• You use data regularly and want the best price? plan. The discounters' promotional prices simply can't be matched with prepaid, and after the minimum term you're flexible on a monthly basis.
• Kid's phone, second SIM, emergency device, or maximum spending control? Prepaid. Here, it's not the price per gigabyte that counts, but the fact that nothing can go wrong.
• You don't want to commit, but you also don't want to keep topping up constantly? flexible plan – knowing that you're paying a few euros extra for that freedom.

And my neighbour? She keeps scratching her top-up cards. That's fine too – given her usage, she might lose two or three euros a month compared to the cheapest plan. For some people, that peace of mind is worth exactly that.
