ORIGINAL STORY: Tesco Mobile is down and not working this afternoon as hundreds of customers are reporting issues with making calls, sending texts and using 4G data.

The service appears to have hit problems at around 1pm with the issues appearing to have gotten worse as the day has progressed.

Independent outage monitor, Down Detector, is showing a surge of complaints with hundreds of Tesco Mobile users currently unable to access vital services.

According to the live outage map, customers across large parts of the UK are suffering from the glitch.
