The top 30 Day Sim-only need-to-knows

Here are the key points to understand when looking for a 30 Day Sim-only contract.

What is a 30 day Sim?

Sometimes known as a 'one-month rolling contract', it is a Sim that you can cancel anytime, provided you give 30-days' notice to your network. This is unlike a fixed-term contract, where you must see it out till the end - usually for a year or more - or be charged to end the contract early.

How do 30 day Sims work?

Just like 12-month or 24-month Sims, your data, call and text allowances will renew every month without the need to top-up. The only difference is you can cancel anytime by giving 30 days notice.

Which networks offer 30 day Sims?

All the major networks in the UK, plus most of the smaller piggybacking networks, offer short-term, rolling 30-day Sims.

To check out the best 30-day Sims, simply select the '1mth rolling' option in the contract length filter option.

FAQs

How do I find a 30 day Sim only deal?

Work out how much data you need each month (the average Brit used just under 6GB a month last year according to regulator Ofcom) and then use this Cheap Sim finder tool to find the best deal for you.

How do I cancel a 30 day Sim only plan?

Get in touch with your network provider and let them know you'd like to leave. But the critical thing to remember is that you'll need to give 30 days' notice.

Will there be a credit check on a 30 day Sim?

It'll depend on the network. Some, such as Voxi, Lebara and Smarty don't apply credit checks, but other networks will.

In general though, credit checks for 30-day Sims tend to be 'soft searches', which are used to confirm your identity and don't usually affect your credit score.

Do I have to top up a 30 day Sim every month?

No. Your data, calls and texts allowances will automatically renew every 30 days and until you tell your network that you want to cancel.
