i thought idevice can receive call/sms as long as they are login with same account? I tested it on my ip13mini, ip7+ and macbook.
The SMS forwarding is handled entirely within iMessage.
Phone call forwarding works when all the devices are nearby, and they can handoff the audio streams between themselves; but you can't pick up a phone call on your Mac if your phone is on the other side of the world/at the office/etc; the feature we're talking about here would not have this limitation.
I think for phone calls this only works on Facetime and for calls maybe only on Wifi.
SMS syncing is true. But if you have a phone and you're out and about you also need mobile data, so would otherwise need a second mobile plan. Or to swap the SIM over, which was easier with a physical SIM, more difficult with eSIMs.
So, popping out the SIM and putting it into a different phone, but with extra paid steps?
>So you can use more than one iPhone as your primary phone. For example, if you have the new iPhone Duo but want to use your other 'standard' iPhone for the telephoto zoom camera capability, you could transfer your phone number from the Duo to that phone for the day if you're going to be out taking a lot of pictures. When you are done, transfer it back to the Duo, and the Duo will become your primary phone again.
Ah, so the functionality that switching the physical SIM card gave you instantly and at no cost at all.
Thanks, I hate it.
