I dont know the phone lock code but if i put old 1 sim it works


The lock does not appear to be on the phone as the old SIM works. The lock is in the new SIM. You have to call the phone company or if you have the PUK code for the SIM you can go to the phone company's website and check how you can unlock the SIM card.

Hi,
My name is Ben and I'm your guru, i.e., a mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.
As you evaluate my advice and suggestions, there are a few things you must keep in mind:
• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew. • A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices. • Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as incompetent. However, you must keep in mind that I can only evaluate and suggest based on the information that you provide.
Subject: How to unlock a cell phone
Customer's exact description:LG 8575 Friend gave me a used phone for my daughter to use but Friend can't remmeber the unlock code to get in phone
Discussion: Problems of this type can be either Phone Locked, SIM card Locked, or Lost Password. Customer did not provide sufficient detail to narrow the problem.
Solution: Provide instructions on how to deal with all three possibilities.
If a phone is locked, the service provider has installed some software on the phone that ties the subscriber ID number on the SIM card to the serial number of that particular phone. If the SIM card and phone serial number don't match, the phone simply won't work. The SIM card won't work in other phones, and the phone won't work with other SIM cards.
Problem areas: The question most honest people ask me is, "Is it legal to unlock a cell phone?" In Europe, the answer is generally yes. Though laws differ from country to country, they tend to favor consumers over companies. In the United States, the answer is also yes. The U.S. Copyright Office issues rulings every three years, and in 2006, they declared that unlocking a cell phone does not infringe on the copyright of the phone manufacturer or service provider, and therefore isn't prohibited. In order to provide the customer with precise information, one must have the following information.
• Phone description including the make and model. • The name of the subscriber's carrier (a.k.a. service provider). • Information as to whether it is the phone or the SIM that is locked.

Possible solutions: The process of unlocking a phone is actually quite simple, and doesn't require any technical knowledge. There are three accepted methods for accomplishing the unlocking. For some phones, you just have to enter a numeric code into the phone. For a fee, some service providers will even give you the proper unlock code for your phone. There are also third party companies that provide cell phone unlock codes for a fee that ranges from $5 to about $25, depending on the model of phone you have.
There is a very high probability that your carrier will unlock your phone at one of its retail outlets. Manufacturers provide their customers (AT&T, Verizon, Nextel, etc.) with the unlock codes. However, if you - the ultimate consumer - write to Sony-Ericsson, LG, Motorola, Nokia, etc. and request an unlock code, that request will be refused. However, be forewarned that some service providers will charge you a fee for unlocking your phone.
Secondly, you can unlock your phone on your own. For some phones, you just have to enter a numeric code into the phone. I don't hand out these numbers because they vary from company-to-company and usually don't work, But if you have the patience, there are several instructional videos on www.youtube.com that provide some useful data. However, I don't recommend them because most of these videos are only free to look at. Yes they are trying to sell you something, like their service.
CNET has several pieces of free software that claim to unlock phones. Click on the following link and perhaps you can find something of interest. Password Cracker

Lastly, for a fee, there are third-party companies that provide cell phone unlock codes at a cost that ranges from $5 to about $25, depending on the model of phone you have. The only company that I recommend is Freedom Unlock and the fee for most popular phones is about Five (5.00) USD. I have no interest in this company and my only contact has been in researching their website.
PUK Codes
A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from AT&T to unlock your SIM card.
Since I don't know the name of your carrier, I'm using AT&T as an example. Most carriers use the same methodology though the wording may be different. You can obtain your phone's PUK code from AT&T in one of these ways:
• Log in to myAT&T online • Use our Technical Support Chat. • Contact Customer Care

To get your phone's PUK code online:
??¸ Log in to myAT&T. ??¸ From the myAT&T tab at the top of the page, hover over the Wireless link and select Phone/Device under the My Wireless Service heading. ??¸ From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading. ??¸ The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card.
Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code. Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator."
You can also do it without any assistance from anyone. However, be sure to read the following carefully because there are pitfalls. If you want to try to do it yourself, just click on the following link: Universal Software Solution for Unlocking a SIM Card
Although most people remember their primary SIM PIN code, those other codes - used for various verification purposes - are never to be found when needed. Below I've included a set of short codes which, when entered on a handset's standby screen, will let you easily change PIN and PUK (short for Pin Unlock Code) codes - but keep in mind, they may not work with all handsets and mobile operators.
More importantly, when changing one's PUK codes there'll be no help to get from the mobile operator if the new codes are forgotten, so make sure to write any changes down alongside the old PUK codes.
The following methodology does not work for every phone. Perhaps you'll be lucky. Also, please note that the codes should be entered without the spaces shown below.
Change SIM Card PIN ** 04 * old PIN * new PIN * new PIN #
Change SIM Card PIN 2 (Write down the new code) ** 042 * old PIN * new PIN * new PIN #

Free unlocking or subsidy code for mobile phones


When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.
