I’ve not heard of it being necessary to own a specific piece of electronic equipment to visit a country before. But this seems to be the insistence here:
All travellers arriving in the UK could be forced to download the new NHS contact tracing app, Grant Shapps has suggested.
The Transport Secretary revealed the Government is considering making possession of the app on smartphones mandatory for visitors in order to keep the coronavirus infection rate down.
This isn’t going to work of course but then such off the cuff political insistences never do. For not only is this an insistence that the smartphone exists, it’s also one that it must remain turned on all the time. If it’s not tracking the movement of the person then it’s not useful. It can only track movement if it’s on.
Further, it can be rather expensive in overseas bandwidth*. Anyone using the app will indeed need to have UK spectrum signed up and paid for. Or, obviously, whatever arrangements their home airtime provider has, not all of which are affordable.
Sure, my technical knowledge is minimal but I do forsee the odd problem with this idea.
*This assumes that the app will interrogate the towers as to location at regular intervals, requiring that data bandwidth. Dunno, but seems reasonable to me.
