A number of Three users have been unable to make calls this morning as the service experiences some issues.
Customers of the popular mobile network have flooded the website Down Detector, which saw more than 2,000 reports of issues at 9.09am this morning.
Around 52 per cent of complaints have been in regards to their mobile phone, 25 per cent say they have no signal and 21 per cent have reported issues with the mobile internet service.
Customers from areas around Glasgow, Edinburgh, Dundee and Aberdeen have been the most impacted according to the site.
The problems have also extended to the rest of the UK, as hundreds of disgruntled customers turned to social media to vent their frustration at the problems.
Tweeting at Three’s support account, one wrote: “What has happened to the service this morning? No signal, can’t make/receive calls, send texts etc.”
Another said: “No phone/mobile signal since 9am, reset phone numerous times and still nothing.”
“No signal whatsoever in Edinburgh, is this a known issue?”, said one other.
A spokesperson for Three UK confirmed that the issue has now been resolved.
The firm said: "Three’s services have now been restored for affected customers. We apologise for any inconvenience caused by the issue.”
