I was able to get this iPhone 11 Pro Max locked to sprint to work with Verizon and T-Mobile in the past. It was working fine on T-Mobile two days ago until my family switched to Verizon now I can not get it to pick up signal.

I tried everything I could and it says Verizon on the top left and on the top right no service bars but says LTE.

I can get into the Sim Applications and tried so many iccids and tmsi auto and manual with no service bars and sometimes get 1 bar than zero again and can’t make calls or get texts.

My iPhone 12 Pro Max is unlocked and this iPhone 11 Pro Max is my other family members.
Please help I’m so confused why it’s not getting any signal bars but says Verizon and LTE.

What should I do?
