A sim only contract is not like a normal phone contract which can be from 12 months to as long as 24 months, as they are only 30 day rolling contracts. This means if you want to change to another deal you would only need to give a months’ notice on your contract and then you would be able to finish your sim only contract with no penalties.

Sim only contracts are great for people that require a flexible contract and don’t want to be tied in for long periods of time. Mobile phone technology moves very quickly so if you tie yourself into a 24 month contract, towards the end of the contract your phone will be very dated compared to the rest of the market and you will invariably be on a worse tariff than newer offers. By having a short 30 day contract you can be constantly on the lookout for the best deal. Once you find the right deal, your contract will continue to roll over to the next month for as long as you want it to.
