iPhone 13 Back-Up & Restore

[kitjv2]

I need to unlock my phone to install an eSIM for a trip to France. I have already backed up the phone to both iCloud & my Mac. But before I erase the contents of the phone, I need to be sure that I can restore everything back onto the phone. Since I have never done this before, I have a couple of basic questions.

1. I understand that the music on my phone (I have a subscription to Apple Music) will NOT be restored from the iCloud back-up. However, since Apple Music is cloud-based, my music will automatically be restored since I have turned on Sync Music. Am I correct?

2. I have quite a few CDs on my phone that I previously uploaded from my Mac. In order to restore those CDs, do I need to store the phone from my Mac (& not from my iCloud back-up)?

Thank you so much for your help. I'm a bit nervous about erasing the phone.

Since your iPhone 13 is carrier locked, you can only add additional eSIMs from the same carrier that it is locked to. Since you want to add a foreign eSIM, this can only be done if your carrier allows it. Contact your carrier and tell them that you will be traveling and would like to use a foreign eSIM while traveling. YMMV.
Afaik, you do not have to wipe your phone to use a different eSIM. Although mine is unlocked, I didn't have to do anything other than add the additional eSIM last year on a European trip. The phone then gave me the choice of which to use.
Regarding your backup, I do not believe that iCloud backs up everything on your phone, so I would recommend that you do a full backup to your Mac, just in case. Check out this link on Apple support.

iCloud Backup helps keep your data safe by making a copy of the information on your iPhone and iPad that isn't already synced to iCloud.
