0871 number call costs. The cost of calling 0871 numbers from landlines normally ranges from 7p to 23p per minute, while calls from mobiles are normally between 8p and 58p per minute.
PPP cover 0871, 0872, 0873 & 09 numbers, not any 084 number at all infact. As 0844 is only charged to the caller at up to 4.26 pence per minute from a BT landline it has been deemed to be not that expensive so not 'premium rate'.
