restriction code

hi i have lg-4050 when i put my sim card it shows phone restricted enter restrictin code the phone is a cingular phone can someone tell me what to do accept contacting cingular?

Who's SIM are you trying to put in the [Cingular branded] phone?
Where did you get the phone from?

I have got it from a friend and I am trying to put a t-mobile sim in it.

I've posted an answer to this is greater detail on another thread. I'll give you the basics...

GSM uses a SIM card which is different than the other authentication mechanisms. Providers (Cingular, T-Mobile, etc.) lock the phones they sell you so that you may only use their SIM cards in the device. The benefit to you is that you get a phone for less than what it would cost you to buy it unsubsidized; the benefit to the provider is that they have a captive audience if you want to use that phone.

for what its worth, there is a lawsuit pending in California right now that I think has merit. The jist of the lawsuit is that the carriers recoup the subsidy on the phone by charging you an ETF (early termination fee) if you leave early; if you don't leave early, the subsidy is paid through the price of your monthly service. Either way, the carrier is made whole. Therefore, except in the case of pre-paid devices, phones should not be locked.

I can't speak from Cingular experience, but when I met the terms of my T-Mobile contract, they gave me the unlock code for my phone. I would think that Cingular would have to do the same if your friend met the terms of their contract.

There are also sites on the web that will provide the unlock codes. Nokia's are among the easiest to unlock, there is software sold on ebay all the time for $7.00. I'm not sure about yours, nor how reputabile the providers of the unlocking service is/are. Once unlocked, you can put anyone's (any provider in any country) SIM card in the device.

thaks for your answer but i have tried contacting cingular there answer is you dont have service with us so we can not unlock it.

You can't blame them for that. You may want to see if you can find on a service/software/etc. on the net - otherwise you may want to donate it to one of the groups that converts phones so they can make 911 calls for people that can't afford cell phones.

Why not just get service with Cingular? They're significantly better than T-Mo in my opinion. (I've had both until recently - just cancelled T-Mo).

for that Lg 4050 is no calculation unlock .. only way to get it done by software direct unlock thru cable .. find a unlocker in your local see they can help you or send your phone to someone unlock it for you
