Hi all,
Just switched my telephone provider from BT to xln telecom. I was fed up with huge bills from BT mostly of which was my diverted calls to my mobile!
I've found it an easy transfer and a lot cheaper calls. Especially landline to mobile (except virgin/3/dolphin) when calls are capped at 30p!
You don't even have to pay your BT line rental its all included in a cheaper price.
Ideal if you're like me and divert my home phone to my mobile when I'm out.
Only been with them for a week but all BT services work the same including call diversion.
