No hard credit search

No hard search. Ever.
Rolling plans are paid up front.
Sorted cheapest first — never by commission. Prices are the provider's standard rolling price and can change.

How we compare SIM deals
GetSIMSmart is a free comparison site, not a mobile network. We don't sell SIMs and we don't take payment from you. Here's exactly what we look at when we list a plan, and how the links work.
Price first
Sorted by the standard monthly price, cheapest first. Never by commission.
Real monthly cost
We show each provider's standard rolling price, not short-lived intro offers.
Data & speed
The monthly data allowance and whether 4G/5G is included.
Network behind the brand
Which of the four UK networks — EE, O2, Three or Vodafone — powers it.
No credit check
Every plan is prepaid or 30-day rolling, not a credit agreement.
Commitment
Rolling plans you can cancel with a month's notice — no tie-in.
Links marked as sponsored may earn us a commission. Your price is unaffected.
No credit check means no hard credit search. Providers may still carry out identity, address or fraud-prevention checks before connecting a SIM. These are not credit searches and do not appear on your credit file.
You are not applying for anything. A rolling SIM is prepaid, so providers have nothing to underwrite and nothing to search.
Work back from what you actually used last month. Most people over-buy by 20GB.
Your current network replies with a code that lets you keep your number.
You leave us here. Checkout is a name, address and card — no credit application.
The number moves across, usually by the next working day. Old plan closes itself.
Defaults, an IVA or simply no borrowing history — none of it triggers a hard credit search on a rolling SIM.
No three years of address history needed. A UK delivery address is enough.
Mid-mortgage application? A rolling SIM is not a credit agreement, so it won't add a hard search to your file.
Detailed, jargon-free guides to help you choose the right SIM-only deal and switch with confidence.

EU roaming included
1pMobile runs on the EE network and includes EU roaming in 46 European destinations at no extra charge — your UK data, calls and texts allowance travels with you. Every plan below is a 30-day rolling bundle with unlimited UK calls and texts, 5G at no extra cost and no speed caps. Prices are the provider's standard rates and can change.
