4g router unlocked

Can someone please tell me in simple plain English,Is it possible to use a unlocked UK 4g router in France with French sim cards? I know nothing about techie things so please be kind

I don’t see why not

there is no reason why not all depends on then network and if you have access to 4g in your area. we do not have 4g in our area but once in awhile we will get a little bit on a good day. most of the time its 3 g


Thank you everyone for your kind answers

Are you still facing the issue?
