This is a unusual symptom in a mobile phone, you should try a hard reset and a factory reset.

1. Hard reset, take the battery out for 30mins and try again

2. Factory reset will reset your phone to factory default settings to so this just go in the settings option and then find the reset option make sure you choose the total reset option

Hope this helps

Firstly to unlock blackberry storm , you have to make sure that you started unlocking with putting different sim card other than your network provider and check with your network provider about settings if you are using GSM network.

Hi hw ar u! ive had my nokia E63 unlocked and every time i put a sim card in it says sim card registration failed please can yoy help me


hi there!

when you said you had it unlocked, it means that the phone has been flashed. meaning, its either can be a good thing or a bad thing, depending on how good the technician (or the program he used) to unlock your phone. just try the original simcard (or the same network provider), use it again, if that works, it means that the phone has not been unlocked and still wont accept other network sim. if it doesnt work on the same simcard and on other simcards at all, i strongly suggest to send it back to the tech who unlocked it for you.

You need to get the correct and full data settings from whatever network provider the sim card is registered to, then make sure when they arrive to your mob. that you go into options of the data txt and install. This should/will sort out your issues.

Contact your network for a warranty repair on the handset every mobile phone purchased has a warranty period of at least 1 year and this covers only manufacturing faults . when you contact your network you will be required to go through some checks just to make sure that it is faulty and that it was a manufacturers fault .

But before calling your network leave the phone swithced on and remove the battery and the sim card .
Put the battery back in without the sim .
Turn the phone on .
When the phone has loaded remove the battery whilst the phone is on .
Replace the sim and the battery and see if this has fixed your problem .  If not you will need a repair

Try holding down Menu-jump to get to the emergency screen. Then hold down on menu-shift-Q and release. It will ask if you want to reset phone. IT WILL RESET AND DELETE EVERYTHING!!!!. It will be like new. Except sim. This works with sidekick 2, not sure with others.

perhaps the phone was reported lost/ stolen by the previous owner... if that is the case, the phone would lock, and not be able to work
