Tips When Unlocking Your Cellphones
Mobile phones make use of two major communication systems. The coded response system or CDMA links the phone to its user to a certain system and number. This is popular in United States, and in some other countries in the world. GSM is another system. This is also called Global System for Mobile Communication. This becomes popular in the United States, and this is the common standard in lots of countries in the world.
For the GSM mobile phones to communicate with other certain network, it makes use of a SIM card. The network provider can lock the mobile phones in order for it not to respond to a SIM card from the other provider. This is for competitive purposes, however, this can be unfair for many. If you will buy a mobile phone, you should have the ability to change it and choose the network you want 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 should determine what type of phone you have. You should not unlock the CDMA mobile phones because it does not use of a SIM card. Once you have determined that it is a GSM phone, then see to it that it is really locked.
You can borrow a SIM card from a friend with various service provider to see if the SIM card works on your phone. Your phone is not locked when you use the SIM card and it works on your friend’s phone. If it is locked, you will receive some error message.
After that, you may begin searching the internet. Search for a company that provides the unlocking code. Once your company has emailed you the code, you need to pay the charges. You need to insert the code into the phone so that it will be unlocked. You will usually get an encouraging message from your cell phone. But you can test it by inserting another SIM.
Unluckily, some models of mobile phones cannot be unlocked using the simple code. The mobile phone service provider who gives the code can know if the model of your cell phone can be unlocked using the code or not. There are times when the cell phones should be connected to a piece of hardware through a USB cable just to be unlocked. You can hire an expert 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.
The owner should not be deprived just because of an unlocked cell phone. It is best to correct this since this is unfair.
