For what regarding SMS, i have enabled them in Messages option on the iPhone.
Settings --> Messages --> "Text Message Forwarding". Here is listed my Macbook PRO, i enable it and suddenly i receive a verification code on it. I write that code on the iphone and the trick is done.
for what concerning Phone calls, go to
Settings --> Facetime --> iphone cellular Calls set to enabled.
Both the devices must be in the same network (WIFI o ETH doesn't matter), i've enabled the phone call forwarding for:
- cell phone number-
- gmail account (the same i use for icloud)
- icloud account, that actually i don't use at all
now, move on your Macbook. open facetime, go to > Preferences > check iPhone Cellular Calls
At this point everything should be ok. If not, the step i performed was to disable icloud account on iphone, disabled icloud account on MBP, rebooted both the devices, then enable icloud account on both of them and everything was working as expected.
Give me a feedback
