On Monday night, Boris Johnson announced that the United Kingdom was going into semi-lockdown, with the public only allowed to go out for essential items, medical emergencies, one session of exercise per day or to commute to work if absolutely necessary.
The government has asked all four major United Kingdom operators to send text messages to their customers, containing information about the new measures created to tackle the spread of coronavirus.
The government has had to enlist the support of operators to send the messages because it lacks the capability to do it itself.
The alert, which started this morning ask people to stay at home, and links to the official United Kingdom government coronavirus response website.
Some users on Twitter said they have already received the message saying: "CORONAVIRUS ALERT GOV.UK".
CORONAVIRUS ALERT New rules in force now: you must stay at home. More info and exemptions at gov.uk/coronavirus Stay at home. "Protect the NHS. Save lives", the text read.

Other countries, including the United Kingdom and USA, are also texting residents.
The UK's National Cyber Security Centre has warned that criminals have ramped up bogus email campaigns that aim to trick users into clicking links that can lead to their computers being infected or seek to fool the recipients into divulging sensitive information.
NCSC operations director Paul Chichester claimed: "We know that cyber criminals are opportunistic and will appear to exploit people's fears, and this has undoubtedly been the circumstance with the coronavirus outbreak".
"Our advice to the public is to follow our guidance, which includes everything from password advice to spotting suspect emails".
