Unless you used the security lock in your phone, your phonebook can be accessed even if your acct is cancelled.
My phone was stolen and I was wondering if they still have access to my phone directory even though I discontinued the service. It was a Samsung e316 with a SIM card under an AT&T contract. I know whenever I buy a new phone, I can still get into my old phone's number directory as long as it's charged, even if it has no service. I've had 2 different phone reps tell me different things...one said yes, they have access to my phone book, and the other one told me no they don't. Does anyone know???
