If you're happy with your existing phone and prefer not to commit to a contract, it's worth considering a pay as you go SIM card. Unlike some SIM only deals, you can pick up a pay as you go SIM card without a credit check, then simply top up with credit as and when you need it. It's a simple, cost-effective way to pay.

There are a few things to consider before you get a pay as you go SIM card. Firstly, you'll need to make sure that your phone is unlocked. If you originally purchased it on a contract deal your phone may be locked to the original provider's network. They should unlock your phone for free if the contract's minimum term has expired, but keep in mind that it can take up to 10 days.

We currently offer a choice of two networks - Vodafone and iD Mobile - and a huge range of pay as you go SIM cards, so you should be able to find a deal that suits your usage and budget. Give some thought to how much mobile data you tend to use (the more you browse the internet or stream digital content, the quicker you'll get through data) and how much time you spend on calls before you select a SIM card. Keep in mind that cards with larger data limits tend to offer better value for money. If you like the idea of limitless data, call minutes and texts iD Mobile offers an unlimited SIM only deal at a great price.
