Guide to buying a mobile phone
If you already have a mobile phone, you can switch to a different network and take your phone number with you, although you may need a different handset. You could get a connection with a new number, using your existing handset.
Networks
When you buy a phone you need to choose a network - O2, Vodafone, Orange and T-mobile are mobile phone networks. Each network is a collection of radio towers all over the country, linked together and transmitting people's conversations.
A mobile phone service usually comes as a package, made up of the phone itself and access to a network. There are five main mobile phone networks in the UK - O2, T-Mobile, Orange, Vodafone and most recently '3' with its growing third generation network which can support mobile video. Other operators such as Virgin and BT Mobile use the 5 main networks and there are many airtime resellers dealing with one or all the networks. They offer two ways of using their services; by "pay as you go" or by monthly line rental. If you do not intend to make a great number of calls from a mobile phone, a pay as you go package may suffice but any reasonably regular use (especially during business hours) probably warrants a monthly package - which package will depend on the volume of calls you anticipate making.
