Tens of thousands of Vodafone customers were reporting that they could not access services including the internet and making mobile phone calls on Monday.

Consumers started reporting problems on the website of the outage monitor Downdetector from about 3pm on Monday.

By 3.20pm the number of reports of service disruption had surged to more than 135,000.

According to a breakdown of the reported incidents, more than two-thirds related to customers who have Vodafone’s internet broadband services to their homes.

Almost a quarter of reported incidents related to mobile internet access, and about 8% of Vodafone customers reported not being able to make calls because of no mobile signal.

Some customers said they also could not access the Vodafone app or website.

The problems appeared to be widespread, with reports in cities including London, Birmingham, Cardiff, Glasgow and Manchester.

A Vodafone spokesperson said: “We are aware of a major issue on our network currently affecting broadband, 4G and 5G services.

“We appreciate our customers’ patience while we work to resolve this as soon as possible.”
