Prime phone networks across the UK have reportedly gone down or are having connection issues, leaving many Brits having difficulty working from home amid the coronavirus pandemic.
All mobile networks - O2, EE, Vodafone and 3 are said to be experiencing problems just a day after Prime Minister Boris Johnson told people to avoid workspaces and stay home.
Reports of problems with O2 initially appeared on Down Detector at around 9:14 GMT, and concerns have been detailed about the connection of other networks.
Many customers have been voicing their outrage on social media after being unable to make calls all throughout the morning.
Some claimed that working from home has been slowed down due to connection issues.
Others complained about their business situation.
As the coronavirus outbreak sweeps across the country, the government has urged people to avoid all "unnecessary social contact" and to avoid venues such as pubs, clubs, and theatres.
The total number of UK deaths from coronavirus rose to 55 on Monday, with over 1,500 cases being confirmed.
