Thanks,

GSM is a very flexible technology. Its main advantage is that all pertinent info such as your phone number and wireless usage authorization is stored on the SIM card. This is the reason why you can easily use another person's phone with your SIM card. Getting the unlocked handset since then you are flexible in being able to use any provider's SIM card.
All else has been said above
