Does my old sim from iPhone 7 support 5 G network if placed in my new iPhone 13 pro
Does the sim from iPhone 7 work in iPhone 13 pro AND support 5G network?
Question marked as
It will fit the iPhone 13 and it will work as it did on the 7 on LTE/4G
Some providers offer 5G on the same contrac, some require a new contract, but there is no such thing as a 5G SIM, only a 5G contract.
Call your provider and ask.
