what happens on a reset

[Javier P]

Do you mean a factory reset? If so, this process will delete all personal information included in your phone. Make sure you have a backup for anything you don't want to lose so it can be restored after the reset.

how about the minutes on the phone

Its only phone data that gets wiped. Usage such as minutes is unaffected

Oh, forgot about your original question

I agree with Pugs, the reset will delete only data locally saved in your phone. Don't worry about your contract data.

Minutes and days are kept on a computer at the network ... unless it's a TracFone phone. In that case, you might wipe the minutes and time - it depends on the phone. (Older TracFone phones keep that data in the phone, and on some of them it gets lost if you reset. They've stopped doing that now, so even if you brought your own phone to TracFone you wouldn't lose any minutes or days.)

Contacts that were entered as Google contacts (not Device or Phone contacts) are synced to your Google account. Emails are kept on the server for an IMAP account. Everything else is lost.
