Did you know that depending on your contract or PAYG tarrif your mobile provider could charge you for calls to 0800 Freephone numbers.
Mine does. I'm with Orange on their Panther tarrif @ £35.00 per month and I still have to pay for these calls.
But there is a way around it.......
0800 Buster
Call 0118 352 0800 from your mobile. This is a UK fixed landline number and therefore you will only be charged at your normal mobile to landline rate. That means that if you have inclusive minutes then you can now call those 0800 numbers out of your inclusive minutes.
