iPhone 12 won’t support 5G in dual SIM mode at launch

I have an iPhone 12 Pro. Currently I am using a physical Verizon sim card. I would like to move Verizon to esim, and install a different sim card in the slot. I am concerned about my inability to use 5G in this configuration.


I have run dual sim in the past (with an iPhone 11 Pro) with great success (it is very useful when traveling overseas) . Has the issue with 5g in dual sim mode been resolved? Anything I have to do on my end? If not, any indication of when this issue will be resolved?


Thank you.

Hi there David Wess,


It sounds like you have a question about using an iPhone 12 with Dual SIM and 5G, and we'd like to share a resource that can help.


Check it out here: Use 5G with your iPhone


Specifically, the detail below may help:

"While using two lines in Dual SIM mode, 5G data isn't supported on either line and will fall back to 4G LTE. In China mainland, 5G data is supported while using two active lines in Dual SIM mode on the line that's using cellular data. In China mainland, while using Dual SIM with 5G, 5G Standalone isn't available."


Cheers!

That is the question, of course. Right now, meaningful 5G is not available to me anywhere I use the phone, but dual sim would be very beneficial. My only current option is to move my Verizon number to esim, insert a physical sim for my second number and give up 5G altogether - I would have to disable my second phone number to enable 5G when/if available/needed. Not good.
