Apple Watch S3 and new iPhone..
I have an iPhone 8 Plus and Apple Watch S3 LTE.
I’ve actually just sold my iPhone and have to post it tomorrow. The problem is my new iPhone X won’t arrive for a few days.
Can I back up, erase my iPhone, post it and rely on just the watch for a few days? I know it will be using LTE a lot more so spank the battery but I should be OK, right?
Then I can restore my iPhone X from my 8 Plus backup and be back in business?
Will I have to unpair / pair or will the above ‘just work’?
