Don't ring 0845 numbers, they cost you money even if you get your phone calls included with your monthly charge.
If you get free calls with BT or Virgin or whoever then the free calls are usually only for numbers that start 01 or 02, everything else is chargeable.

It tells you all about it and lets you search for real phone numbers instead of your 0845 0870 etc chargeable numbers. Don't be tricked by charged at local or national rate numbers. If you get inclusive minutes they will most likely be chargeable for these 'local rate' calls.
