Sim Only Plans If you own a phone but there is no sim card, you should get the sim only plans. Sim only plans are available from many networks in UK such as Vodafone, Orange, O2 and T Mobile. Sim only plans are divided into two categories. One is the sim only monthly and another one is the sim only pay as you go. Sim only contracts mean you need to give in a 30-day notification should you want to terminate the service.

Sim only monthly allows you to save more money as you only pay for the services and not for the phone. When you subscribe to a sim only monthly plan, you do not have to be tied up to the contract of 18 months or more but just one month commitment, meaning you have to give a 30-day notice for termination when you want to terminate the service, which is way better than the 18 months contract.
