O2 has blamed a technical glitch for the widespread problems that hit its mobile network this week.
Thousands of customers were left without voice or data connections for as long as a day and the company said in a statement that the problem was “due to a fault with one of our network systems”.
This means some mobile phone numbers were “not registering correctly on our network”, it added.
GiffGaff and Tesco Mobile, which make use of O2’s network infrastructure, also suffered outages, but O2 has now restored full service.
It said in a statement that any customers still having problems should restart their handsets, adding it was sorry for the disruption.
The problems began at around lunchtime on Wednesday (July 11th) and lasted until Thursday. The company succeeded in restoring 2G service by yesterday morning, but took longer to completely fix 3G capabilities.
Customers used Twitter to vent their anger at the downtime and O2 has won plaudits for its handling of subscribers who tweeted their frustrations.
