“Does 5G work with Dual SIM?
When using two lines in Dual SIM mode, 5G data isn’t supported on either line and will fall back to 4G LTE. If customers are using eSIM only and are on a 5G supported carrier and service plan, they’ll have 5G access.”
The Verizon slide MacRumors obtained also says you’ll have to remove your physical SIM to access its 5G network with an eSIM. If Apple truly is rolling out an update to change that within this year, then you probably won’t have to remove SIM cards or make do with a 4G connection for longer than a month or so. The iPhone 12 and the iPhone 12 Pro will start shipping on October 23rd, while the iPhone mini and the iPhone Max will be available starting on November 13th.
