Here's my question: I'm willing to wipe my phone and set it up as new to see if this fixes the issue but I can't work out a few things. Maybe some of you folks can help?
- In the US, we have ONLY e-Sim. I'm with T-Mobile. I transferred across from my 13PM to the 14PM during setup, but what happens if I wipe this phone completely? Will it automatically still retain the e-Sim and just allow me to set it up or will my number disappear into the ether? I have to work so can't be without a phone all day - but wonder if anybody else has had this issue? Bear in mind that I won't be transferring it from another phone like I was before.
- If I set-up as new, I know I have to install my apps again one by one. That's fine. But presumably all passwords come across from my iCloud keychain when I sign in. Will this be the same with things like known wifi networks.
- I have iMessage cloud sync. Will my 'new' phone with no messages immediately download them from the cloud or will they be lost to me?
- As above, but MUCH MORE IMPORTANT TO ME - WhatsApp. I am European living in the US and WA is way more prominent (and dare I say, functional) than iMessage so I have years worth of conversation history in there to keep. I know they normally restore from the iCloud backup when restoring a phone but are they tied to the app or the backup? Meaning when I download WhatsApp from the App Store to my 'new' phone, will I be able to download my message history from iCloud too? Or will they be lost?
- What about my Apple Watch - currently paired to by iPhone 14 Pro Max. What happens with that? Will that have to be setup as new or can I restore that from backup too? (Bearing in mind I believe the backup for an Apple Watch is usually tied up within an iPhone iCloud backup.)
If you know the answers to any of these definitively, please let me know.I don't want to waste a whole day of my life doing this only to then find out that I lost everything.. Thanks in advance guys.
