I have spoke to rep over the phone to get a Verizon sim card (better coverage in my area). The rep said he would send a V1 card. From what I found here, the V1 doesn't support 5G (the rep told me otherwise!). The rep also said the X3 card would be Tmobile.
So I just want to have a sim card that would be using Verizon, and in the same time supporting the 5G. Is that possible?
