0844 numbers are almost never included in any 'free' minutes or talktime included in a phone package. From a BT landline, an 0844 number will typically cost up to a maximum of 5p per minute to call.
Calls to 0800 or 0500 numbers are usually free of charge from a UK BT landline and mobile phones. Calls from other providers may vary, and could cost up to 40p per minute. Calls to 0345 numbers are the same costs as a call to a standard '01' or '02' landline number, even when calling from a mobile. Calls to an 0345 number are also included in any bundled minutes or free talk time that covers landline calls.
