Re: i want unlock code

Sony-Erric is well secure with it's CID technology and can be unlocked only by skilled technician knowing this. Don't trust any code generator or code provider service for this as it is reported unuseful for many times. It will proved costly and useless. Smart software tools can only do this with attached phone's. Remote unlocking is not advisable. Ask Fixya for such technician nearby you and see your problem solved....

How to correct sim card error / insert sim card

Procedure to follow

Step 1: Check the sim tray or sim seater to see if it it broken, if it is, replace it
Step 2: If the sim seater/tray is not broken, clean the entire terminal.
Step 3: If the sim seater/tray is not directly on the board, trace the broken led and solder it, or you replace the broken led with another sim tray.
Step 4: If it is still not working, change the battery and put a new battery, because a virus infected battery will always give such problem.
Step 5: Finally, if the problem still persist, then check the sim card and replace with another sim card if the former is bad because a bad sim card will always display such message as insert sim card or sim card error.

I'm trying to unlock my BB storm 9530,after I type "MEPPD" I enter "MEP2" or "MEPP2" but still I dont get any window to put the unlock code in,any ideas ?!

Before you start, you MUST have an Unauthorized Sim Card inserted. An unauthorized Sim Card is a Sim Card that is NOT belong to the provider of the phone. Example: If you have a Verizon phone, you need to insert a T-Mobile Sim Card inside the phone before turn it on. 1. Power on the phone.
2. Phone will said "MEP check failed. Do you want to enter MEP unlock code". Select Yes.
3. "Enter Network MEP code (# left)". Enter the unlock code.
4. Press Enter, you should see “Code Accepted”
5. You need to check Network Connection is set on GSM/UMTS. Menu>Manage Connection>Mobile Network Options and make sure it GSM/UMTS.
6. Once GSM/UMTS is selected. You can now ready to make phone call.
Notice: If the network not working after your phone is fully charged and unlocking process “Code Accepted”. You must change from Verizon CDMA network to GSM Global Network a few times, after change from Verizon CDMA to GSM Global 3 times is completed, leaves it on GSM Global Network. Now it should work. (Verizon 8830 World Edition DOES NOT work in USA)

Unlock from 3 network

as far as i am aware it is only the service provider that can unlock a 3g phone but if you go to a mobile repair shop ask them or ring one out of the phone book and ask them if a phone is reflashed or bebranded can it be unlocked if so the price would be £30/£40 quid hope this helps
