Very poor to no signal strength on my galaxy s22 ultra

You are under a 3-year payment plan on the phone, that is not a contract. You can pay off the phone at any time and switch to a different service provider, either using that phone, or using it as a trade in at your new service provider of choice

I traded in my phone during the att promotion when the s22 came out which required a 3yr plan canceling any time b4 that will result in having to pay them the full original cost of the phone so while I could technically switch carriers it would cost over 1000$ to do so. The signal issue seems to be with the phone itself I had att for my last 3 phones and this is the newest phone I ever bought and also the only phone I've had any signal problems with so using it with another carrier wouldn't help. 

canceling any time b4 that will result in having to pay them the full original cost of the phone so while I could technically switch carriers it would cost over 1000$ to do so.

This is incorrect. You are required to pay the remaining balance on the phone if you have been receiving credits since February, you have received nearly 1/3 of the credits against the full cost of the phone. If it was $1,000 phone you would have received about $333 in credits, leaving approximately 666 remaining balance on the phone..

Both Verizon and T-Mobile have switch offers. T-Mobile's would cover the full cost. Verizon's is more limited. It's time for you to check both of those networks and see which one would work for you and which one offers a deal that would compensate you for the loss of credits
