this is the manual for the phone. Download it and it will show you how to change your password.

It happened to me the other day... My phone worked for a call, then I took a nap with my headphones plugged into the phone. Then, I bleive what happened was I pulled the headphones out without turning the music off. Then my phone had the same problem. Also, my music would not play without headphones.

I tried to goto Verizon today and they gave me the runaround. Then tonight, I had the phone plugged into a soundboard at my bar to play music and I pulled the cord without turning the music off and it started playing out of the phone as normal. Then I tried calling my friend and it worked. The text problem went away too.

If you contact Samsung, they have a backup code that they have when the person forgets the code.

Hi,

You will need a PUK code from your network provider. Call them as its free.

I hope this helps,

Thanks.

CLick OK, goto Settings and Tools, Sound Settings, Call Sounds, Call Ringtone, My Sounds and select the name you saved it as.

there is no sim card its a verizon phone they dont use sim cards go to your vzw store and they can transfer all your info to a new phone for you

you need to convert your music to wma format if you are using an sd card
