[Q] Verizon note 4 T-MOBLIE having issue when I make a call please help

Hi i want to know if anybody is having the same issue or if anybody knows how to fix it. I'm using a verizon note 4 on t-mobile 5.01 lollipop , everytime i make a call when the 4G Lte sign is up my 4G Ltd sign and the signal bar disappears but the call still gets connected. I just can't accept calls or go online but if I have a 3G or H + sign, my call goes through fine I can receive calls and I can go online.

native video calling on tmobile network

Has anyone found out how to get the video calling icon active on T-Mobile with the Google version of the pixel... I know if you pop a Verizon sim card in and activate HD & video calling through Verizon it pops up... I've called T-Mobile and I've been told my account is provisioned for those things already.. my VoLTE works.. and I've always had native video calling for my last 4 phones. So I'm just wondering of anyone has figured it out.
I don't have T-Mobile myself, but I found that it worked for a guy here.

Have you tried going into the hidden Phone menu and verifying if Video Calling is provisioned? You need to be running Nougat, and although I don't have a Pixel, I assume you are... Look under "phone info" and scroll down... To access the hidden menu go into Phone, select the dial pad, and enter *#*#4636#*#* and the menu will appear... Please update us on what you learn.
I was wondering the same thing myself I went into the hidden phone message with the sequence that you gave and the video calling provision is turned off I turned it on and exited and then when I went back in it automatically turned itself off again there is an option to update something but once I press update it says update error but it doesn't stay turned on the video calling provision I don't know how to set it to stay
please explain how to get the Pixel XL video calling to work on T-Mobile.
Can someone please explain how to get the Pixel XL video calling to work on T-Mobile. Please please please please
