Codes may vary in Eurobell areas and I think Eurobell codes are similar to BT's.
Mercury Cable and Wireless has purchased Energis and codes may vary on ex-Energis lines. The above codes do not apply to Bulldog and indirect customers as they are using BT lines and have to use BT's service.
NTL franchises may vary.
The service is cheap on all networks except BT. BT stick out like a sore thumb on this one!
