Everything Everywhere, which was created last July when the Orange and T-Mobile UK operations were merged, is planning 30 new UK stores this year. All will be branded ‘Everything Everywhere’ and will offer Orange and T-Mobile products and services.

The company opened five own-brand shops earlier this year as a trial. It says footfall at these stores was up over 25% compared to other communications retail stores.

Mobile News reports that network infrastructure firm Arqiva has won a High Court action against Everything Everywhere.

It says the Technology and Construction Court has ruled Everything Everywhere's attempt to combine the Orange and T-Mobile UK networks breaches contracts with Arqiva. Everything Everywhere is said to be appealing against the judgement.

T-Mobile has confirmed that around 4% of its UK customers have been overcharged due to a problem with its billing system.

Calls diverted to the T-Mobile voicemail service were charged in error, with 'ghost calls' appearing on customers' bills.

Chinese telecoms manufacturer Huawei Technologies has been awarded a four-year contract to upgrade the Orange and T-Mobile networks operated by Everything Everywhere.

The work will improve reception, expand HD voice calling and will also prepare for a move to 4G LTE technology.

Everything Everywhere, which runs the Orange and T-Mobile UK networks, has released outline results for the first quarter of 2011. It says mobile service revenue was up 1.6% year-on-year, although overall turnover was down 1.7%. (Both figures exclude the effects of regulation).

Orange and T-Mobile now have 27.7 million customers between them.
