Apple ID
I am currently in dispute with a big cellular service provider about closing my account over bad cellular phone service. I switched to another carrier and I have a new iPhone 14proMax . I am having difficulties using my usual Apple ID . I am being charged twice for Apps and my email addresses are not syncing. My old devices are not syncing either. Will it be best to change my Apple ID with this new service and sync this new system and service? Is there a way to do this?
