Xfinity says phone unlocked but it is not supporting ANY sim.

Xfinity locked Pixel 8 pro has caused so much misery and I am out of more than a thousand dollar if I include my pixel 7 trade in.

I paid the entire amount for the phone and xfinity says its unlocked. Called, chatted, went to store and all say its unlocked but

don't know why any sim is not supported. Tried tmobile, verizon, redpocket and every time I get a msg to contact xfinity support

to get it unlocked. The store experience was the worst. The best they offered is wish me luck. 

Never again am I buying any locked phone.
