LTE does not stay connected

[MordechaiGMC]

Hi - I have a Samsung Note 9 and the LTE connection does not work.

When I restart the phone, it says LTE and I'm able to send MMS (photos) or stream video.

However, after a very brief time, or after I move around with the phone or lock the screen, it goes back to the "H" connection. At that point, my ability to send photos, stream or even surf the internet is HIGHLY limited.

I have worked with my provider and Samsung and nothing works. I have checked all of the basic settings.

Is this a common glitch with the Note 9 and Note 10 (which I tried and also failed to work)?

IS there a fix?

Please help. I'm desperate -- have not had LTE in months and can't do half the things I need to do (mainly text images).

THANKS!

What is the exact model of your phone? Who is your carrier?

Any thoughts on the screen shots?

I honestly don't have a clue, as someone who has previously owned a Note 9 I know it supports 4G LTE all the Samsung's I've owned have had a network selection mode like in my image
