subject: A Comprehensive Guide To Unlocking Your Cell Phone [print this page] Mobile phones operate on two key communication systems. There is the CDMA and the GSM communication system. CDMA system is actually a coded communication or response system in which the phone would be tied to a particular service provider as well as number. GSM cell phones however use SIM cards in order to tie to connect to a particular service provider or network. GSM cell phones have become quite popular in many parts of the world.
Due to the intensive competition among network providers, some of them have been locking their cell phones in which case SIM cards from other providers would not be used in them. Many people have deemed this to be quite unfair. Of course you would not want to buy a cell phone yet be limited as to the ability of changing the network provider or the SIM Cards. This is especially when you are always on the move to other parts of the world where you would not have network coverage from the network provider. This underlines the importance of unlocking your cell phone.
When unlocking your handset, you first need to know the phone type. CDMA phones do not use SIM cards and therefore unlocking them would be immaterial. Secondly, when you have ascertained that it is running on GSM communication system, you would need to determine whether it is actually locked or not. This should be simple as you would only need to get a SIM card from an alternative service provider then see whether it will work on the phone. In case it is actually locked, an error message will be displayed otherwise it will open just like it would with your SIM card.
Next, you will need to research over the internet so that you can get a company of good repute to provide you with unlocking code. You should expect to be charged some fee before they email you the code, which underlines the importance of ascertaining the reputation of the company. Once you have the unlocking code, you will only need to key it into the cell phone thereby unlocking it. In most cases, you will get a message from your cell phone but in case it does not, you can always insert another SIM and see how it reacts.
You need to note that some cell phone models wouldnt be unlocked using simple codes. However, the mobile phones unlock service providers will always determine whether this can be done or not. In case it would not, then you would have to connect the phone to hardware through USB cable so that it can be unlocked. Purchasing the cell phone unlock software and hardware is quite possible.
