Never have I so often had no data/ phone reception unavailable since I moved over to BT. Is this common? And then when it comes back on it H or E reception.
Usually it's between 4G and H+. The checked states 4G area.
Is it the indoor or the outdoor data signal which is failing?
H+ is one step below 4G. E is very slow, but can you get E indoors?
Is it an Android phone?.....there are apps you can install, to show mast locations.
