Vodafone is investigating and has apologised for the inconvenience, with dedicated teams working to restore connectivity.

This follows a similar issue experienced by Virgin Media O2 on Tuesday, with over 50,000 customers reporting problems.

Vodafone has also faced customer anger over mid-contract price increases and the timing of the outage.

The actual number of affected users is unclear, given that they require alternative access to the internet to report the issue.

Vodafone has confirmed that its 5G mobile network is not affected.
