Re: other sim is not being accepted by w550i

The lock code is from your previous provider. They have apparently locked your phone into there company. You can ask them for the code but you will probably have to pay a small fee to release your phone. Or you can go online and find the code if you know how to look for it. Ebay sells codes to release your phone as well if that is any help to ya. Hope this helps and good luck.

Insert correct sim card

Are you getting Sim card not accepting error message? If it is so then your Sony Ericsson W550i is locked to a particular network. To fix this you have to unlock it. Use unlock code to unlock your mobile from its network lock. To get the code you need to submit network provider, country and IMEI number of the mobile. Make sure yourself whether you have knew the network provider to which your mobile is locked, country to which the locked network belongs to and IMEI number of your mobile. If not you can find the IMEI number in two ways:
1)Go to Options>status
2)Find IMEI on the back of your mobile, behind the battery.
3)Type *#06# and press call button. It will display your IMEI number.
You can find the network provider to which your mobile is currently locked by switch off your mobile and switch on it again. A logo of the locked network will get displayed on your mobile screen. After knew all these get the code from the site ,by submitting these to them. Unlock it yourself using unlocking instructions which is given in the site itself.

Phone puked

yes, the puk code is required when the pin code is written wrong 3 times, to get the puk call your phone service provider the puk is not related to the phone so if you put in another sim card it will work, or if you put the locked sim card to another phone then the other phone will ask for puk.

its simcard protection incase its stolen, 3 times wrong and its locked, eventually if you enter the puk code wrong too many times it should make the sim card useless so call your phone service provider its your only option.

Forgot SIM lock

Did you try so called "puk" codes? If you did this that I'm afraid you will have to visit your operator. :(

W600i puk


The PUK is unique to your sim card. You need to get the PUK code from your mobile operator from where you got your sim card.
