About SIM Only Deals

Our SIM Only deals bring you all the minutes, texts and data you need, just without a new handset - making them a much cheaper option! And with 30-day, 12-month, 18-month and 24-month contracts, they're flexible, too!

Nope, it's absolutely free! So is the delivery. You just have to pay for the tariff itself.

When you buy a SIM Only plan, there’s no handset cost to factor in. You’re just paying for the minutes, texts and data allowance.

Absolutely! Simply text the word 'PAC' to 65075 to get your PAC code. Then when you receive your new SIM card, contact your new network quoting your temporary number, existing number and PAC. They’ll sort it all out for you.

Of course you can! If you love the mobile you already have, there’s no need to change it. Just purchase a compatible SIM card, insert it into your handset and you’re good to go.

UK networks are already rolling out their 5G infrastructure, which means 5G SIM cards are now available. Keep an eye out for a 5G icon in our SIM only deal listing for 5G compatible SIM deals.

We only sell "Multi SIMs", which means you can pop out the right size SIM card you need for your mobile. Basically, our SIMs will fit in pretty much all UK mobiles!

There are tonnes of network benefits available on SIM only deals. Take a look at the icons beneath each SIM only offer to find out what perks and extras you can get, depending on the network you choose for your SIM only deal.
