These days 90% of devices are compatible with all carriers. Before switching, I would contact T-Mobile and see if they can help you improve the signal. Some carriers don't let you seith until you've been through a full billing cycle.
I'm trying to understand what you are asking. Are you saying that you have a Tab S9+ that was carrier locked to Verizon, but is now unlocked and you switched to T-Mobile and are now not picking up the T-Mobile signal? Or is it still locked to Verizon and you have switched to T-Mobile without unlocking? Are you considering purchasing a Tab S9 carrier locked to AT&T hoping it will work better? It will only work better if you switch carriers to AT&T, as you cannot use a device locked to one carrier on another. You can purchase an unlocked Tab S9, which you can use with any carrier, or you can purchase one from T-Mobile. If you are having issues with a carrier signal, the primary solution is not to immediately buy another device, but to contact the carrier and try to troubleshoot the problem.
Verizon doesn't lock them. I bought the tablet from Samsung and it's verizon but I'm using it on tmobile it's not getting good signal. I'm wanting to know of the att model will be a better fit since there both gsm carriers?
