Cheap prepaid SIM: the card is the smallest bill you will pay
The sticker price of a prepaid SIM is a one-off, and usually a small one. What the line costs over the months after it is the part worth working out — including the bill nobody expects, which arrives when a number is left to go quiet.
What a prepaid line actually costs you
Four things, paid to three different people, on three different schedules. Only one of them is the price on the SIM packet, and it is the one that matters least.
| What you pay for | Who charges it | How often | Why it matters |
|---|---|---|---|
| The SIM itself | Whoever sells the line — the operator, a retailer or a budget brand. | Once, at the start. Often close to nothing, and frequently sold with starter credit already on it. | Never ours. There is no SIM to buy here. |
| The credit or tariff on it | The operator that owns the number, priced in their currency. | Every time the line needs money, for as long as you keep it. | This is the recurring one, and it dwarfs the card within weeks. |
| The service fee on a top-up | Us, for delivering that credit to the number. | Once per order. It depends on the country, the operator and the amount, and the figure is on screen before you confirm. | The only line on this page we set — and the only one we can show you in advance. |
| Letting the line lapse | Nobody charges it. It lands as a repeat of row one. | Once, and unexpectedly — when an unused number is recycled and the next trip or the next month starts with buying another SIM. | The cost nobody budgets for, and the easiest of the four to avoid. |
We are one row of that table. There is no SIM card to buy here, no tariff to sign up to and no unlimited product of any kind — what this service does is put credit on a number that already exists. Where the card itself comes from, and which kind of seller suits you, is set out on buying a prepaid SIM online; the difference between prepaid and a monthly contract is on the prepaid SIM overview.
Four questions that decide the running cost
None of them is answered on the packet, and all four are worth a minute before you commit to a network rather than after.
How often will it need money?
A line topped up once a month and a line topped up weekly are not the same running cost, because each order carries its own service fee. Fewer, larger loads is the cheapest shape when the usage is predictable — the arithmetic behind that is on recharge prices and offers.
What happens if you skip a month?
Every prepaid line has a window of inactivity the operator will tolerate before it starts closing things down. How long that is, and what goes first, is theirs to set — and it is the single biggest difference between a cheap line and an expensive one. How long a prepaid SIM lasts covers the mechanics.
Does the price you were quoted hold?
Introductory pricing is common on prepaid, and it is the operator's to end. Whether the figure that sold you the SIM applies to the second period as well is in their terms, not on the box — and not something any third party can promise you either way.
Is what you use actually included?
A tariff that looks cheap because it excludes the thing the phone does most is not cheap. Inclusions are often national only, so calls abroad and use of the line outside the country can sit outside it. Plans and tariffs goes through what to read before committing.
The cheapest line is the one you do not have to buy twice
Row four of that table is avoidable, and avoiding it is the only genuine saving on this page. A number that is left alone long enough stops being yours.
Keep a number alive- The smallest load the operator accepts is usually enough to reset the clock. Keeping a number costs far less than replacing one.
- Do it before the window shuts, not after. Once a number has been recycled there is nothing to top up — the order is simply refused.
- A refused load costs you nothing: the full amount comes back with the service fee included, and the operator's reason comes with it.
- Nothing here does it for you. There is no scheduled recharge and no card kept on file, so a quiet line only stays alive when someone remembers it.
The failure itself — a SIM bought abroad, left in a drawer, recycled before the next trip — is one of the four ways a prepaid line goes wrong on the prepaid SIM overview, and the trip-shaped version of it is on prepaid travel SIM.
About prepaid SIM deals and offers
There is no deal to find here. We run no promo codes, no cashback and no seasonal offers, and there is no field at checkout to type one into. What you pay is the operator's own value plus a service fee that depends on the country, the operator and the amount, on screen before you confirm.
Real prepaid deals do exist — they belong to the operator selling the line, or to a wallet or bank app running its own campaign. Which of those can reach an order placed here, and which cannot, is mapped out on recharge prices and offers.
A cheap SIM says nothing about calling abroad
A low entry price and a good international rate are set by the same operator but sold as different things, and one does not predict the other. A budget line can be expensive to dial out of, and a mid-priced one cheap.
Those per-minute rates are the operator's, published by them; we neither set them nor carry the call. What we do is keep the credit on the line that pays for it. The difference between calling another country and using the line in another country — two things the word international covers — is set out on prepaid travel SIM.
Prices and offers, question by question
Payment, refunds and delivery questions are answered in the help centre.
Open the help centreHow much does a prepaid SIM card cost here?
Nothing, because there is none to sell. The card is bought from an operator or a retailer at their price; this service starts afterwards, when the line needs credit. What we charge is a service fee per top-up, shown with the total before you confirm.
Can you tell me the cheapest prepaid SIM in my country?
No, and be wary of any site that ranks them for you. Entry prices, included allowances and expiry windows change constantly and differ by region, so any table printed here would be a snapshot going stale. The operators' own pages are the only current source.
Is there a discount for topping up more often, or in bigger amounts?
No. There is no promo code, no cashback and no negotiated rate for volume — order fifty and the price is the price of order one. The one thing that genuinely lowers what you pay us is fewer orders, because the fee is charged per order rather than per amount.
What is the smallest amount I can put on a line?
The operator sets that floor, not us, and it differs by network and country. Whatever they allow appears in the catalogue for the number once you enter it — if the small load you used to make has vanished from the list, they have raised their minimum.
I topped up a cheap SIM and the credit never arrived. What now?
If the operator refused the load — an expired line, a blocked or recycled SIM — the full amount comes back to your card with the service fee included, and their reason comes with it. Credit that was delivered shows as an operator reference code on your receipt, which is what support works from.
