Mostly it is software problem . You reset your phone to factory settings this will reinstall the software once again .

Also ensure Sim is in proper condition .

My Blackberry curve 8330 doesn't show any of the apps. All I can do is call and text, but I can't receive them. I have error code 523 and I already downloaded the blackberry desktop software, but...


Try connecting to your pc and using the blackberry software to back your phone up then reboot to factory settings. Reboot may erase all of your contacts so make sure you have them all saved to your sim card you will lose your pictures unless you upload them to your pc. If that doesn't work I would take to a ATT store and they can do it for you. They will not save your contacts to your sim. Corporate stores will transfer your phone contacts and whatever else they can save to your sim or a new one. Authorized dealers lack the equipment to switch all of you info to a backup sim.

Im getting a initialization failure error, its not the SIM card, i switched SIM cards with another phone. i have AT&T but on the phone it says my mobile network is T-mobile. i already tried application...


Your phone still locked only for T-mobile network, that's why you got error message when you change your sim card. You must unlock your blackberry using blackberry curve 8310 unlock code for T-mobile network. Blackberry unlock code can be obtained from your network provider in this case T-mobile or you can buy from third party sites. Both of them will take you some charge but third party sites have lower cost and quick delivery service rather than network provider.

Blackberry Curve 8310 error message "SIM not allowed." How do I fix it?


Make sure that you are using the SIM card that came from your wireless carrier.

Try removing the battery from the back of it while it's ON. Leave the battery out for five minutes then put it back on.

If same problem occurs, contact your wireless carrier.

Have a great day!
