What is the B and P in a box icon?

These icons are in the top left of my iPhone 13 pro max screen when I pull down to options. I have internet so not sure why it says No service. Any help is appreciated. T-mobile is the carrier.

Those are your two lines for your “hard” nano-SIM abn your eSIM. (i.e. Dual SIM)


It’s showing the “B” line has no signal.


The B and P are the first letter of your self-assigned line name in Settings -> Mobile -> Mobile Plans. (Primary and Backup maybe ?)
