How much does it cost to call an 0870 number on BT?

0870 numbers have been something of a controversy in recent years. They have become well known as expensive telephone numbers to call. Many large organisations and complex organisations continue to use 0870 telephone numbers. This leaves many people wondering exactly what they will be charged for making such a phone call. However, if you are with BT, you are with one of the phone providers that are attempting to tackle the issues with business 0870 numbers head on. If you are on most of the usual BT call packages then calls to 0870 numbers will be included in your package. This means that you will not incur any additional charges for telephoning such numbers. The only real exception to this is if you are on a unlimited weekend call package. This means that outside of the weekend, you will incur charges to 0870 telephone numbers.
