Now just what in tarnation are Unlocked GSM Cell Phones? Well, there is the question of GSM and then there is the question of unlocked. Both of these questions can be answered quickly and be understood with little knowledge of technology or phones altogether. In fact, I bet a person that has never heard of Boost Mobile Cell Phones can understand what Unlocked GSM Cell Phones are by the end of this article. With GSM technology a mobile phone comes with a SIM card. This card can be removed and placed in any other phone that accepts SIM cards. This means that the phone is not traced to you rather your SIM card is. So a mobile service carrier doesn't mind you to a single phone per se, rather to a SIM card. Now, on the flip side if you have a phone you like and you're comfortable with the device you can switch service providers without losing the phone. Instead you just need to switch from the old service providers SIM card to the new providers card. Here's the tricky part. And trust me, it's not that tricky. Some companies lock their phones. This means that a phone you purchase may only work with that companies SIM cards and therefore no switch could be made.
