Three investigates 999 calls not getting through during outage

There have also been several thousand reports of problems from users of Smarty and ID Mobile.

Three has apologised after thousands of people reported they were unable to make phone calls on the UK mobile network. "We're aware of an issue affecting a small percentage of voice services, our team are working hard to fix this as soon as possible," Three said in a post on X. It is not known whether customers will be able to claim compensation for the outage, although according to the website of telecoms regulator Ofcom, it "may be appropriate" for providers to offer refunds "while repairs are being made".
