No Credit Check SIM Only Deals – No Rejections, Just SIMs

Looking for a SIM-only deal but worried about your credit score? You’re not alone. Thousands of people in the UK get declined every year for mobile contracts due to poor or limited credit history. The good news is: you don’t need to go through a credit check to get connected. In this guide, we’ll show you which networks offer no credit check SIM only deals, how they work, and how they can even help you build trust over time.

What Is a No Credit Check SIM?

A no credit check SIM is a plan where the mobile network doesn’t check your credit score when you sign up. These deals are perfect if:

• You’ve been rejected for a contract before
• You’re new to the UK and don’t have a credit history yet
• You simply want a hassle-free, flexible plan

Most of these SIMs come as 30-day rolling contracts or prepaid plans, where you pay in advance or monthly with no long-term tie-in. As there’s no risk to the provider, there’s usually no credit check needed at all.

Networks That Don’t Do Credit Checks

Here’s a list of networks in the UK offering SIMs with no credit checks:

Can a No Credit Check SIM Help My Credit Score?

Not directly — because most 30-day SIMs don’t report to credit agencies. However, many networks keep internal records of your payment history. Paying on time consistently helps build trust, and after a few months, you’re often accepted or they will ring you themselves to offered a deal or upgrades.

Example: If you start with a Lyca 30-day SIM and always pay on time, you may be eligible for a 12–24 month plan later — still without a credit check. Trust builds credit opportunities.
