Seems the answer is more complicated than that. I am currently trying to run my phone in dual SIM with Mint (T-Mobile) as primary and Verizon as secondary. The Verizon SIM only works if I set the "Data service network" option to Verizon. If it is set to T-Mobile, I lose all service on the Verizon SIM. I am attempting to figure out this issue with support, but so far I've only gotten a response that the phone doesn't support CDMA networks even though Verizon fully decommissioned CDMA on January 3rd, 2023. So if it's your only SIM, you may be okay, but if you plan on using dual SIM, it likely will only work if you have Verizon as a primary, but don't expect any support if you run into issues.
"Thank you for your patience and patronage! According to the ASUS Store page, the ROG Phone 7 is not compatible with Verizon networks, so unfortunately, we do not have any solution for this issue.
