What Phone Do You Use?

My primary phone is an Apple iPhone 12 Pro with 128GB of storage, and a space gray color. This phone supports 1 Nano-SIM, and 1 eSIM for up to 2 cellular lines. As of September 20, 2021 – both lines are active. In addition, I have a SIP client which accepts SIP calls from 2 providers. Unlike my cellular lines where I am limited to a maximum of 2 active lines at a time, for my SIP client, I can support many more SIP accounts, but for the time being, I see two as sufficient enough.
