To block calls on your Curve: 1)In the phone, press the Menu key 2)Click Options 3)Click Call Barring 4)Highlight the call blocking option you want 5)Press the Menu key 6)Click Enable 7)Type your call blocking password. To stop blocking calls, highlight a call blocking option, click the Menu key and select Disable. Please note that call blocking is not associated with your device, but instead with your carrier and your SIM. You will need to contact your service provider to purchase/enable call blocking – they will provide you with a password for the set-up listed above (which, by the way, I lifted directly from my Curve – must give credit where it is due!). Hope this helps! I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_8b8c2cd6ce148309

If the cord is fine, then chances are the usb port in the phone is dead. Which results in the phone being dead and worthless.I'm sorry about that. It is actually a common problem.

Unlock as in use for another carrier? And where did you get this "unlock" code?ALL paid unlocking services are a scam. The only people to unlock correctly is your carrier. Your carrier takes your request, sends it to RIM. RIM then sends them the unlock code. And in about 24 - 48hrs you'll get an email with the instructions and code.So... If your Blackberry OS is "Nuked" your gonna have to reinstall the OS, or get another phone.Nuked OS Re-installation instructions:http://crackberry.com/blackberry-101-lecture-12-how-reload-operating-system-nuked-blackberry

Debris gets stuck under there. Get a can of "forced air" blow it on there while rolling the ball. If that doesnt get it out.. There are youtube videos on how to take the trackball out and clean it, but be careful. The 1st time I did that, I broke a lil prong off the housing trying to get it off.. and some of the parts are very tiny, and try to roll away. So be cautious if you go that route.

maybe no network available in your place or in your setting u did not set up exactly

Chances are it's clogged with dirt and other debris. I suggest using a Q-tip© lightly dipped in rubbing alcohol and run it around the ball and move the ball and just clean it off. That should help.

If not, the ball probably needs to be replaced

Try to take it apart into the smallest pieces you can and put it in a place it could dry up, to tell you the truth probebly its dead but if its dry and still doesnt want to turn on take it to a mobile fixing store

try this ? > find: manage connections and click it make sure "mobile network" has a check next to it but if its unchecked, clikc it to checkmark the box then enjoy!

Pull the battery.

Pull the battery and leave it out for 30 secs to allow the internal memory to clear. Put the battery back in. If you still have the issue, then you will need to have the hardware replaced. If you have no warranty and are feeling adventurous, you can try to replace the keyboard yourself, but these devices are a bit tricky to pull apart.

Typically this is an indication of the service being kicked off or being removed from the enterprise network. Check to make sure that you are getting your typical "signals" in the top right-hand side of the device (EDGE for AT&T or whatever indication in addition to the bars that you usually have there to indicate data service). If you are only seeing bars, your service provider/data plan/enterprise information has been kicked off your device. This happens when you SIM card is not in the proper place, your service provider had an update that you either didn't download or a provider glitch. I would advise the following: - Check that you SIM card is in the proper place (sometimes is slides) - If that doesn't work, I would call your network provider to ensure that you are still activated with data service - If this is a work account, your IT department will need to reactivate your enterprise information, which means re-installing your device on the network.
