Public Telephones
Both companies provide public call boxes, although the majority are provided by BT. Full instructions on how to use the telephones are displayed in the call box.
BT call boxes.
These are glass type cubicles with either the word "Telephone" with red markings, or "Phonecard" with green markings, along the top of the cubical.
"Telephone" call boxes accept 10p, 20p, 50p and £1 coins, and some will also accept Access, AmEx, MasterCard and Visa credit and charge cards.
"Phonecard" call boxes do not accept cash. They will only accept pre-paid cards (which are about the size of a credit card) which are obtainable from main Post Offices and most newsagents. Also, some Phonecard boxes will accept Access, AmEx, MasterCard and Visa credit and charge cards. Phonecards are obtainable in £2, £4, £10, and £20 denominations.
Mercury call boxes.
These are blue and silver/gray cubicles. Currently, the majority only accept Mercury phonecards (which are similar to BT phonecards), in 50p, £1, £2, £4, £5 and £10 denominations. Additionally, some Mercury call boxes accept Access, AmEx, MasterCard and Visa credit and charge cards. Mercury phonecards are obtainable from British Rail train stations and major newsagents.
Generally both BT and Mercury phonecard call boxes tend to be used less than standard call boxes; often one will be available right next to a standard call box which has a queue of people waiting to use it. If you are likely to use a public call box, having a phonecard could save you having to queue up to make your call, or the need to have change.
