The phone comes with a suitable SIM already installed

The system (or at least the settings shown) is slightly different with the AT&T-compatible Tracfone SIM, where I have the option to turn off VoLTE (with Verizon-compatible SIM, that option is missing, because you have to have VoLTE, because I don't think this phone has CDMA radio for the Verizon 3G network which will be discontinued in about a year; only Verizon 4G LTE -- the title of this listing is probably inaccurate and just means the phone comes with a Verizon-network compatible Tracfone SIM)

But maybe it does not matter and you can swap in a different Tracfone-compatible SIM later, and the system settings will adjust to it; don't know and don't want to mess with the SIMs unnecessarily to test
