I got a European phone that didn't support any of my carrier's 4g bands. I can use it do stuff on 2g or 3g if I have to, but it's so painful to use I don't end

I got a European phone that didn't support any of my carrier's 4g bands. I can use it do stuff on 2g or 3g if I have to, but it's so painful to use I don't end up reaching for it unless I really need it.
