Deals to switch to tmobile?

I had t-mobile for 15+ years and switched to ATT back in 2024 because they offered a better deal for phone line + new phones; however, service has been crap and I'm looking to switch back. Technically, I have about 15 more months on my line to pay off the phones. Does t-mobile offer any plans to switch from ATT and what's the best package to get at the moment?
