Calls between different networks not working
Update: According to an O2 spokesperson, the key issue was that people were unable to make calls between networks.
The spokesperson said: “Today the industry experienced an issue that meant some calls between different networks were unable to connect. Specifically, O2, Vodafone and Three were unable to connect to EE and EE customers were unable to connect to O2, Vodafone and Three.
“At a time when the country needs connectivity most, it is important we work together rather than pointing fingers before facts have been determined.
“As this was a problem for a multiple networks, there is a National Emergency Alert for Telecommunications and Ofcom call at 2:30pm this afternoon to determine the route of the issue to ensure this doesn’t happen again.”
EE said that data and 999 calls were not affected. It added that the network issues were not related to an increase in remote working.

This is a cross industry issue and our technical teams continue to investigate, working to resolve the issue as quickly as possible. We apologise for any inconvenience.”
