Do pay monthly SIM only plans need a credit check?

Contract plans of 12 months or longer usually do. Every plan listed here is a 30-day rolling or pay as you go SIM. These are not credit agreements and are generally supplied without a hard credit search, though a provider may still carry out identity, address or fraud-prevention checks.

Can I keep my current mobile number?

Yes. Text PAC to 65075 from your existing phone, then give the code to your new provider when the SIM arrives. Your number transfers, normally within one working day.

What if I have poor credit or no credit history?

Rolling SIM only plans are paid in advance, so providers are not lending you anything. Bad credit, thin files, recent arrivals to the UK and under-18s in some cases are all accepted.

How do you make money?

When you click through to a provider and buy a SIM, we may receive a commission from that provider. It never changes the price you pay, and it never changes the order of the table — that is sorted by price and data only.

Will the SIM work in my phone?

Any unlocked handset works. If your phone is locked to a network, ask that network for a free unlock code before you switch. Most listed providers ship a triple-cut SIM and several offer eSIM.

How a 30-Day Rolling Plan Works

A 30-day rolling plan is a fixed monthly bundle of data, minutes and texts. You pay for the month ahead, and the plan renews automatically every 30 days until you cancel it. There is no 12 or 24 month commitment — you are only ever tied in for the month you have already paid for.

It sits between pay-as-you-go and a fixed contract. Unlike pay-as-you-go, you get a generous bundle at a fixed price rather than paying per minute or megabyte. Unlike a fixed contract, you can leave, change your allowance, or switch networks at each renewal with no penalty.

Every rolling plan on GetSIMSmart runs on one of the UK's four physical networks — EE, O2, Three or Vodafone — through smaller brands that rent capacity on them. You get the same masts and signal as the host network, usually for a lower price.

Lyca Mobile's 30GB plan is pay as you go rather than 30-day rolling, so it is not listed above — but it offers similar flexibility and is worth comparing on the main deals table.

Benefits Versus a Fixed Contract

For airtime alone, a 30-day rolling plan beats a fixed contract on almost every measure that matters to a regular user.

Feature	30-day rolling	Fixed contract
Commitment	30 days — cancel any time	12–24 months locked in
Credit check	Generally no hard search	Hard credit search
Change allowance	At each 30-day renewal	Locked for the whole term
Switch networks	Any month, no penalty	Early termination fee
Price rises	Leave before they bite	Locked in, often inflation-linked
Handset	Bring your own	Often subsidised across the term

Switching Between Rolling Plans

One of the best things about rolling plans is how easy they are to leave. The whole switch normally takes a working day, and you keep your number.

1Pick a new rolling plan and order the SIM (or eSIM, where offered).
2Text PAC to 65075 from your current phone to get a Porting Authorisation Code.
3When the new SIM arrives, hand the PAC to your new provider — usually online or by text.
4Your number transfers across, normally within one working day, and the old plan closes automatically.
5Set a calendar reminder for a few days before each 30-day renewal if you want to review or switch again.

For the full walkthrough with common pitfalls, read our guide on switching SIM without losing your number.

Credit Checks on Rolling SIMs

Because a 30-day rolling plan is paid in advance, the provider is not lending you anything — so there is no credit agreement and generally no hard credit search. These plans are not credit agreements.

A provider may still carry out identity, address or fraud-prevention checks. These are not credit searches and will not appear on your credit file, so they do not affect your score. This makes rolling plans a strong choice if you have a thin, damaged or non-existent credit file, or you are in a mortgage application window and want to avoid any hard search.

30 days, cancel any time No hard credit search

Frequently Asked Questions

What does 30-day rolling mean?

A 30-day rolling plan is a fixed monthly bundle of data, calls and texts that renews automatically every 30 days until you cancel. There is no long-term contract — you pay for the month ahead and can leave at any time with no penalty. It is the most flexible way to get bundle value without commitment.

Do 30-day rolling SIMs require a credit check?

No hard credit search is generally run. Rolling SIM-only plans are paid in advance, so they are not credit agreements. A provider may still carry out identity, address or fraud-prevention checks, but these are not credit searches and will not appear on your credit file.

Can I keep my number when I switch rolling plans?

Yes. Text PAC to 65075 from your current phone to get a Porting Authorisation Code, then give it to your new provider when the SIM arrives. Your number transfers within one working day and your old plan closes automatically. See our switching guide for the full walkthrough.

Are rolling plans more expensive than fixed contracts?

For airtime alone, rolling plans are usually cheaper or comparable, and far more flexible. Fixed contracts only look cheaper when they bundle a subsidised handset — and over the term you typically pay more than buying the phone outright and pairing it with a rolling SIM.

Will my rolling plan price go up?

Prices can change, but because you are only committed for 30 days you can switch to a cheaper plan any month. Fixed-term contracts often include inflation-linked mid-contract price rises that you are locked into — rolling plans avoid that risk entirely.
