Mobility and other value added services apart, another reason for this unprecedented growth is that against one BT line many a times represents one family, mobile phones are personal, thus has a larger customer base. A single home numbered family may account for multiple mobile phone connections.



This surge is aided by the sim free phone or the pay as you go phones. Owning a contract mobile phone may look more attractive with incentives like free handsets and free talk time and texts. However, for a low user, this equation may not work out. The term 'low user' could be anyone from your 15 year old kid to 75 year old grandfather. The best option for such cases is a sim free phone.

Sim free phones are also popular with the younger generation, especially students from both UK as well as the rest of the world. Advantages of a sim free phone includes -

1.You're not bound by a contract so can change the handset or service provider at will.

2.You can watch on your spending and avoid paying huge mobile phone bills.

3.There are no monthly commitment so one thing less to worry about.

A sim free phone could be bought from any store or the Internet. They are the 'unlocked' version of contract phones. Functions and applications offered in sim free phones are same, although certain features like 3G or EDGE are network specific. As for the functioning part, since almost all mobile phone manufacturers have their sim free models, there should be no problem for one to pick up the right mobile for the job.
