Well if you are tied to a particular network all you have to do is to unlock your phone to use it any other GSM network. You can get the unlock code through online. I will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.

Showing invalid sim


The most common thing for any mobile/cell phone.
Easy fix simply take an eraser & rub over the contact of the sim card then making sure not to touch the sim cards chip re-insert in to the phone & it should be problem solved. If the problem still exists insert in to another phone if possible to test the integrity of the sim card if the sim card works in another phone it could be the phone you are attempting to use it maybe faulty or the sim card is incompatible or the phone is not unlocked entirely, if it doesn't work in another phone the sim card has failed & a new sim card is required.

Just got the phone and installed the SIM card from my old phone. having problems setteng the code for locking the phone


Hi,

Let me give you a little background and then some solutions. This is generic because I don't know your carrier. I'm useing ATT as an example.

Phones are naturally unlocked, but a service provider might lock them

When originally manufactured, all GSM cell phones are unlocked. That is, they can be used with any SIM from any cellphone service provider - always assuming, of course, that the cellphone service provider has compatible GSM service on the same frequency bands that the phone can operate on.

Most cell phone service providers electronically 'lock' the phone so that it can only be used with their service. There are obvious reasons why they choose to do this - in particular, to force you to pay what are usually very high roaming charges when you take your phone out of their network and use it elsewhere in the world.

Fortunately, this locking is reversible. With some phones, it is possible to simply enter an unlocking password code into the phone and it is immediately then unlocked. Other phones need to be connected up to a special unlocking data terminal.

Your phone has to be unlocked by the carrier. LG, Motorala, Sony Ericsson, Nokia and most of their ilk, will not give consumers the unlock codes but don't despair.

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 your carrier. For example, if you have AT&T to unlock your SIM card, you can obtain your phone's PUK code from AT&T by:

● logging in to your myWireless Account online
● using their Technical Support Chat
● calling Customer Care at 1-800-331-0500

To get your phone's PUK code online from ATT:

● Log in to your myWireless Account.
● Select My Services under My Account.
● From the My Services screen, select My Phone/Device.
● Select Unblock SIM Card.
● The Unblock SIM screen will display your PUK code.


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 ATT 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."

There are three other ways to unlock a phone:

● The carrier will unlock the phone for you at one of its retail outlets;
● You can do it yourself by clicking on this link Free Unlock Codes ,
● Pay $3.89 at the following website: www.theunlockshack.com/.

I trust that this is helpful and solves your problem. All the best

I enter the wrong pin & i have the block my sim card please give me puk code my sim number is 899660138000823603 & mobile number is 00966535657942


PUK stands for Personal Unblocking Key. This is a uniqueeight-digit code specific to your SIM card. This is required when the PINnumber to unlock your mobile phone is entered incorrectly 3 times. You are thengiven 10 attempts to enter your PUK code. If an incorrect PUK code is enteredafter the 10th attempt, you will block your SIM card permanently and willrequire a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways - The PUK code is in your SIM card documentation Starter Pack.If you do not have this then -Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give themyour account details and they have confirmed your identity.

Please insert Ur Sim Card


Clean your sim card with a dry cloth and your phone interiors with a blower/dryer. There might be some moisture. If it doesn't work, your sim is corrupt. Get a duplicate sim from Your sim card supplier i.e. your operator service.
