In order to understand the advantages and disadvantages of unlocking your cellphone, It is first necessary to understand specifically what this terminology refers to. Unlocking your phone is unrelated to jail breaking and other software modifications that give the user a higher degree of customization. Rather, unlocking simply refers to removing the restriction on your phone that prevents it from being used on other carriers. For example, if you purchase a phone at a discount because it is bundled with a two year Verizon contract, it is almost certainly locked to Verizon’s network, meaning that it cannot be used on AT&T, T-Mobile, or any other network besides Verizon.
Cellphone providers typically use either a GSM network or a CDMA network. GSM network providers, such as AT&T and T-Mobile, use SIM cards that can be removed from the phone and replaced with new ones. CDMA phones do not use SIM cards. Only devices that use SIM cards can be unlocked. Therefore, if you are on a CDMA network, there is no way for you to unlock your phone. If you want to switch networks, you need to have your network provider switch the device over for you. With a GSM phone, you need to get a cell phone unlock code in order to unlock your device. Once you have done this, you can freely choose to use whichever GSM carrier you prefer.
Unlocking your phone can bring many benefits. For one, you are not restricted in your usage of the phone. An unlocked AT&T phone will work on T-Mobile’s network. Also, unlocked phones are very useful if you travel frequently. If your phone is locked, you might have to purchase a cheap, prepaid phone to use when you travel, instead of just using your primary cellphone and switching providers on the fly.
