As for using the Apple ID on multiple devices, you can do that. As mentioned earlier, it has nothing to do with the actual telephone service you are using. If you are using iCloud to sync data, then turning on iCloud on the new device (if it doesn't do aso automatically) should effect a copying of all data using iCloud to the new device as outlined in Transfer data from your previous iOS or iPadOS device to your new iPhone or iPad - Apple Support

The phone number is not linked to you iCloud account. If you log into the phone with the same iCloud account it will just transfer the info stored in iCloud to the new phone.
