Mobile phone network operator EE has apologised after around 27 million of its customers were affected by signal problems yesterday (March 19).
A technical error meant that many customers were prevented from making phone calls, texting or using the internet during the day.
"A technical issue has been causing some of our customers to experience problems with their signal," a spokesman for the company said.
'Gremlins in the system'
He added: "This issue has been resolved for many of those affected, and normal service for all customers should resume shortly.
"We apologise for the inconvenience caused to our customers."
However, angry customers of the firm took to the social networking site Twitter after the company, which is a conglomerate of Orange and T-Mobile, had tweeted that it was aware of "Gremlins in the system".
Richard Antwi said: "Customer service @EE getting it so wrong with the humour. What is there to laugh about when the service has been down for 2 hours?"
EE recently named best network provider
And another of the group's customers, Megan Kelly, said: "Must be on at least 6 hours without signal now? Sort it out @EE".
The technical hitch marked a turnaround for the company, as it was recently named as the best network provider in the UK by consumers.
EE was placed first or in a tie for first in every category in the RootMetrics report last week, which found that major networks provide "hugely varying" levels of service in the UK market.
