Connectivity issues after switching from T-Mobile

[zackmo]

I've been with Verizon since 2005, but switched to T-Mobile for a year in 2018. I'm now back with Verizon and brought the iPhone 8+ I bought from T-Mobile to Verizon. I was told before I signed up with Verizon that the phone is compatible and will work with no issues. Ever since I switched, I keep losing service and data slows to a halt. I'm now having issues with calls and texts - either they never get to my phone or they get duplicated and received 4+ times.

I walked through troubleshooting with a chat representative and tried everything they recommended - I even got a new SIM card from Verizon but that didn't help. I'm starting to think I was misled with the fact that the phone bought through T-Mobile will work without issues on Verizon. Any help and advice is appreciated because this has been a a real pain and is causing stress and unneeded missed communications.
