O2 has admitted another outage on its network is affecting the ability for customers to make calls and access data services.
V3 noted several customers complaining of a lack of service on Twitter.
Any other iPhone users on O2 in the UK still receiving 'no service' on their signal? Unable to receive calls or texts in the past few hours.— Richard Buxton (@Richard_Buxton_) October 12, 2012

An update on the firm's Status Page confirms the error is still ongoing.
"We've got some problems with our phone service right now. Some phone numbers might not be working. Those numbers are not location specific," it said on the page," it said.
A spokesperson for O2 told V3 that some 10 percent of its customers have been affected by the issue but it hoped to have it fixed by the end of the day.
"Some customers will already have had their service restored and we will have a full fix this afternoon. We are sorry for the inconvenience this has caused those customers," they added.
The incident could well prove embarrassing for the firm after a major outage in June left millions without services. This forced the operator to promises compensation to customers that likely totalled several millions.
The issue also comes as its rival EE prepares to rollout 4G networks on its existing 2G spectrum which could well entice customers to jump ship to the operator to take advantage of the services.
It is likely to be at least six months before O2 itself will have similar services up and running in the UK, though.
