Hi, I'm getting no 4g.havent since owning the phone.it will show lte but that's it.im in the UK. Using plusnet, coverage is perfect for all surrounding areas..iv done all sorts of checks suggested by Samsung.even tried a new sim card..the odd thing also is if I take the sim out and put it into my old note 9 it will instantly find 4g..sort of my last chance with it before I sell it
You'd be better off taking this case to your carrier's support team. Maybe your 4G data isn't enabled in settings or your account's data is switched off.
I bought it 2nd hand from ebay.decent seller and came with accessories also still has warranty. I'm wondering isit an American phone as I feel iv done everything possible..do the UK phones show LTE I always thought it was an American thing
