Youโll probably need to contact care to do this due to the fact that one of the phones will be deactivated after you move one to the other. Itโll be easier to use eSIM on the 13, otherwise you will be without service while waiting for a SIM to be delivered. Youโll probably have to use your online account to download an eSIM onto the second phone since there wonโt be an active phone to move the account from. It would be simple if you had a 3rd phone you could use temporarily. Youโd move phone 1 to phone 3, move phone 2 to phone 1, then move phone 3 to phone 2. That could be done right from the app.
