Tips When Unlocking Your Cellphones
Cell phones use two major communication systems. The coded response system or CDMA links the phone to its user to a certain system and number. This is popularly used in United States and other countries of the world. There is also the other system that is called GSM. This means Global System for Mobile Communication. This is getting more popular in the United States, and this is the usual standard in many countries in the world.
The GSM mobile phones make use of a SIM card in order to communicate with other certain network. The network provider has the ability to lock the mobile phones so that it will not reply to other providers. This is for competitive purposes, however, this can be unfair for many. When you buy a cell phone, you should have the right to change the SIM card and use the phone based on the network you choose to use. As a result, the phone can be used in traveling especially in other countries without paying extra roaming charges.
However, one question you may have in mind is how do you unlock the cell phones. You must know the type of phone you have. Because CDMA cell phone does not use a SIM card, there is no need to unlock it. Once you have determined that it is a GSM phone, then see to it that it is really locked.
You can try borrowing the SIM card of your friend just make sure that it is from another network provider to know if the SIM card will work on your phone. When you use the SIM card and it works on your phone then it is not locked. You will get an error message when it is locked.
After that, you may begin searching the internet. You may look for a company that provides the unlocking code. You will need to pay the charge after the company emails you with the code. After you have entered the code, the phone will be unlocked. You will usually get an encouraging message from your cell phone. However, to evaluate further, you can insert it with another SIM.
However, some mobile phones are not unlocked even if you use a simple code. The cell phone service provider who gives the code can determine if the model of your cell phone can be unlocked using the code. Sometimes, the cell phones need to be connected to a piece of hardware through a USB cable just to be unlocked. You can have the someone to do this for you. It is also possible to buy the hardware so that you can unlock the phone.
However, you may need to pay more.
