Text Message "Not sent. Tap to try Again"

I'm having the same issue of texts not sending but also finding out from my wife and kids that I don't get some of their texts.  It's frustrating.  Talked with tmobile and their answer was to turn off 5G, reboot the phone, change the sms functions.  None of which works.  I'm also having issue with the phone coverage randomly not connect, so dealing with a brick for hours on end.  T-mobile lady told me there was nothing they could do and this is a motorola issue.  I've had samsung for years and thought it might be fun to try a different phone.  Worst phone decision ever. 

Anyone have any luck with tmobile cancelling this phone and transferring to another phone?  I just don't want to pay for this phone anymore. It doesn't work, why should I pay to move to a phone that works?
