O2 customers are about to be cut off from millions of Wi-Fi hotspots as O2 ends its deal for customers to use BT Wi-Fi on 1 July.
O2 will be relying on BT's behind-the-scenes tech to get its 4G network up to speed.
BT is planning a 4G network of its own -- maybe even teaming up with old friends O2 to take on EE, Vodafone and other mobile rivals.
BT, EE and TalkTalk are among the most complained-about companies for pay-TV, broadband, mobile and landlines, according to Ofcom.
Calls to Freephone numbers are already free from landlines, but will eventually be free from mobiles too, Ofcom has ruled.
The UK's major networks, along with BT and other network companies, will be bidding for slices of spectrum in January.
A new service from BT offers movie and TV companies relaible, high-quality connections direct to customers, but critics say it threatens the open nature of the Internet.
