So I have a T-Mobile Iphone 7 Plus that was unlocked by T-Mobile a few weeks back. I'm trying to use this cell phone on Verizon but running into issues. It shows connected to Verizon but no bars. Data or calls do not work. I've verified with Apple that this phone is unlocked. I've done a iTunes restore and setup the phone as a new device but nothing. I've done a reset on the phone as well as a network reset. I can pop the T-Mobile sim back in and everything works fine.
