There are a variety of reasons why cell phone service providers electronically lock the phone so that it can only be used with their service. One reason is to force you to pay a high roaming fee while you are outside of their network and using it in another part of the world, which is why most cell phone service providers do this. Because this electronic lock is breakable, it is easy to simply enter an unlocking password code into some phones in order to bypass the lock entirely.

There are some phones, however, that must be connected to a specific unlocking data terminal in order to be unlocked and used. The first thing to determine is whether the phone can be unlocked or not, and the answer is that all GSM phones can be unlocked because the whole locking/unlocking phones concept does not apply to non-GSM phones because in non-GSM phones, your number and account are tied to your phone rather than to the movable SIM chip that is contained within the device. The simplest method is to use a phone that can be unlocked by just entering a secret code into the device.
The code is typically a one of a kind number that can only be used for that specific phone, and it is determined by the phone’s serial number and the service provider who locked it. For the vast majority of mobile devices, as well as several other types of phones. It will cost you no more than $5 and will be simple to type on your phone. Another method requires that the phone’s ‘firmware’ its operating system software be modified in order to remove the lock completely. This necessitates the use of a specific data cable to link the device to a special programming unit. A simple method of obtaining the code number is to contact your service provider and inform them that you wish to unlock your smartphone.
The service provider may require a notice period of a few weeks. They may also charge you a ‘unlocking cost’ based on the circumstances under which you obtained the phone; for example, if you were on a postpaid plan, they may need you to have remained on that particular network for a minimum of 12 months before charging you an unlocking price. The mobile service provider will then supply you with a code, which you will need to enter into your device in order for it to be unlocked instantly. Alternatively, if your service provider refuses to assist you because of “policy,” you might use this method.
