I switched my iPhone 7 trac phone to spectrum. Do I have to do a factory reset?

Hello Bottacamp,

Thanks for choosing the Apple Support Communities. We see you switched carriers and have questions. If you only switched carriers, a restore is not necessary. So long as the iPhone is unlocked to work with another carrier, you should be good to go. For info on how to unlock your iPhone for use with another carrier, please follow the link below.

We hope this helps.

Cheers!
