Sim only deals are a cheaper alternative that allow you to continue using your mobile. Just like a phone contract, you still have your minutes, texts and data in your plan. The main difference is that it can be a much cheaper option. The length you are tied in to your contract is generally a lot shorter.

Sim contracts are perfect for people who have come to the end of their mobile contract but want to keep using their phone. Alternatively, you may have bought a handset outright, as a cheaper option to a lengthy 2 year contract.
