Security code nokia c7 00

Sounds like it is PUK Locked AKA SIM Locked. Contact your cellular provider as they are the ones that have locked it at firmware level using an unbreakable 128 bit security key. The pass code is 6 numbers. Sometimes this will activate if someone tries to open a phone's consumer set passcode incorrectly more than 4 times, or if the phone is reported stolen or if they have tried to contact you about account arrears and you have ignored them. Sometimes it is just a mistake :>).

I was going to go hiking with my biology class i noticed that my phone died because it was uncharged i couldnt charge it so i left it in my pocket when i get to somewhere i could charge it IT WONT TURN ON...

how long did you charge it? given that the phone died on you and also given that there is quite an amount of power needed to start the phone up I'd recommend you to just be patient and wait for at least 5 minutes of charging before trying to turn it on. should work after that. good luck

Where can i find a puk code

Hi the PUK code is the security code for the sim card and not the phone, all you need to do is call your service provider ( so if the sim card is with the orange network you call orange) and ask them for your PUK code they will give you this code for free over the phone and this will then get your sim card working again.

its not worth guessing the code as its 10 digits long and random the only people who have this number is your service provider so give them a call and they dont charge for this service.

now if you dont need that sim card you could just get a new sim card and this wont ask for the PUK code and you get the PUK code written on the card the new sim card comes with, but if you have info on your sim card such as texts or numbers then the best option is for you to give your service provider a call and they will sort you out in a couple of minutes

they dont charge for this but write the code down in case you ever need it in the future, the code will only work with the sim card thats asking for the code so dont try it on another sim car as you could block it

let me know how you get on or if you need further assistance ok

My xenon keps shutting down n sometimes wont send or recieve text

Bring your phone into an AT&T store for evaluation. The service delay could be Sim Card based, or could be phone based. As for the Shut down problem, This could be a number of things. I would need to physically view and handle the phone to properly diagnose. Any AT&T employee worth their salt should be able to get this fixed, or at least offer alternatives.
