iPad Pro Not Receiving SMS Messages
I've exhausted every option I can think of, so now I'll come here and ask for help.
My new iPad Pro can send/receive iMessages, but it doesn't receive forwarded SMS (text) messages from my iPhone 6S. This worked perfectly with my old iPad Air (and still does) but SMSs are not appearing on my new device. I have two-step verification enabled so I didn't receive a code for forwarding set-up, all devices are connected to the same wifi network and signed into my apple ID, iCloud features all working as they should ... but SMSs don't appear "forwarded" on my new iPad Pro.
I've even:
1. restarted my phone and iPad,
2. toggled off iMessages on my iPad and removed it from forwarding on my iPhone (and re-enabled it)
3. tested iMessages between myself and my neighbour (different wifi networks obviously) and that works fine,
4. waited a few hours, had a cup of tea, walked the dog ... and still the same thing. No SMS (text) messages are being forwarded from my iPhone to my iPad Pro (but they do arrive on my old iPad Air).
5. Double-checked settings on old iPad Air against new iPad Pro, and they're the same.
Can anyone help me with this please? Many thanks in advance!
iPad Pro, iOS 10.2.1
