My china mobile IMEI:-35269500557980 and when sim is putting it was say invalid sim pls tell solution sir


Hi,
Please follow the instructions carefully but if the code fails to work, then ,make no more than 4 attempts as it may lock your phone. Can you let me know how you get on with it as well please. Thanks. Please also make sure that you back up any information on your phone as in certain cases the resetting also removes your contacts from the SIM and your pictures. j700 unlock method Basically the SP lock needs to be removed before the Network lock is disabled, so if you only have SP lock on, you need to turn the Network lock back to active, disable the SP lock and then disable Network lock. A reminder 'how to' is below: Do a custom reset: *2767*2878# once this has finished rebooting turn the phone off. Next a SIM card from a different service provider needs to be pushed half in - (Push it fully in then slide it back out by about 1/2 a centimeter), Turn on the phone - you will now see an "Insert SIM" message, Now perform a full reset: *2767*3855# When the phone powers off, quickly push the SIM card fully in, and let the phone power back up. After you do the reset, check and make sure that your Network lock is active by pressing *#7465625# If it isn't active you must use this code to reactivate it: *7465625*638*00000000*00000000# Then you have to deactivate the SP lock first. To do that you need to input: *7465625*77*00000000*00000000# (this will reset the lock) Then you enter: #7465625*77*00000000# (to disable the SP lock). Then you disable the Network lock: #7465625*638*00000000#

I need to unlock a samsung j600 phone please, or at least do something that would let me use an orange sim card in it instead of o2...


Sir, I think you mean the network is locked. In that case, you have to contact O2 to unlock your mobile from their network. This way you will get any sim to work on your mobile.
Thank you Sir, Have a nice day.

Need unlock code for my samsung vodafone


Try this it work for me

1- Enter code *7465625*28782# without a sim in the phone
2- Phone will display "Auto Subset Lock: Activated!"
3- Enter code *7465625*28638# without a sim again
3- Phone will display "Auto Network Lock: Activated!"
4- Now insert the sim and enjoy! Phone is Unlocked!

(NOTE: When you change sim to other operator repeat this process to unlock it for that operator also)

I found this in another thread. All credits for the solution to Morfeus of the FuriousTeam!

I myself haven't got a locked Z500 so i cannot try this. But other people confirmed this as working. I'd like to hear more results on this!

I also found a list of service codes. I guess you could use some of them to enter your unlock codes manually(that you read out with WinIMEI).

Check Versions of h/w s/w f/w:

*#1111# S/W Version
*#1234# Firmware Version
*#2222# H/W Version

*#7465625# = Check Locks
