Unfortunately, there are some people who will take advantage and spend their time writing scams in order to convince others to part with their money. If you have any doubts about something then go to your browser separately and do a search on it.
The picture below is a screen shot of a genuine text message from the UK Government. I received this and did wonder if it was true. Instead of clicking on the link in the text, I went to Google (other web browsers are available) and searched for something like “uk government text coronavirus” and was directed to the Government website confirming it was genuine. That page can be found here.
