Most homes already have a telephone line (called a landline). When you move house you should inform the telephone supplier. You can choose to change supplier.
Not all people choose to have a landline. You may decide that you only want a mobile phone. There are several commercial companies offering mobile phone packages. Some of these are 'pay as you go'; this means that you have to buy a card to put money (also known as credit) on your phone.
Others have a monthly fee plus additional costs for calls that are not included in the fee. Prices differ between companies, and according to the number and time that you call. Check and compare prices before you sign a contact with a mobile phone company. Contracts are usually for a fixed period such as 12 months.
In the UK it is illegal to use a hand-held mobile phone while you are driving; if you are caught doing this you could be fined and receive points on your driving licence; points on your licence could lead to you paying more for car insurance. Even if you use hands-free phone while driving and cause an accident, you can still be charged with careless or dangerous driving. Calls to the emergency services are free.
