SIM only deals

Most mobile phone deals and offers are a combination of the perfect handset and the perfect tariff. For some people, the call and text package is the only important part of the mobile phone deal.

For those of us who already have the perfect handset and are simply looking for a great deal on calls and texts, the best mobile phone deal is a SIM-only deal. A SIM-only mobile phone deal does exactly what is says on the tin, giving you a mobile phone SIM card without the handset.

SIM-only mobile deals are great if you already have a handset you love. Most UK mobile phone networks offer at least one SIM-only mobile phone deal.

Perhaps you have just come to the end of your contract and you are looking to get a new mobile phone deal. If you are happy with handset you have, then you can get a SIM card for the existing handset and carry on using it as before, only with your new number.

What is a SIM card?

A SIM card is a microchip around the size of a postage stamp holding all of a mobile phone's configuration information, for example the mobile phone number and call plan. Without a SIM card, a mobile phone will not work. SIM stands for Subscriber Identity Module. Once a SIM card has been activated it is permanently locked to the particular network, though not locked to a particular phone. That means you can easily change mobile phone handsets but keep your phone number, your friends’ phone numbers and any saved messages or photos.

Why choose a SIM-only mobile phone deal?

Maybe you want to keep a couple of different mobile phones for different purposes? Perhaps you spend a lot of time outside hiking or playing extreme sports? With a SIM-only mobile deal you can keep an inexpensive basic handset for when you're off on your adventures, and a nice top-of-the range handset to pull out of your pocket in business meetings.

Which networks offer SIM-only deals?

SIM-only mobile phone deals are available from all the major mobile phone networks including:

  • Orange
  • O2
  • Three
  • T-Mobile
  • Virgin
  • Vodafone
