BENEFITS OF UNLOCKING YOUR PHONE:

• Allows the customer to use various wireless carriers across the world. Often, a subscriber can benefit from purchasing a prepaid SIM in the visiting country/region as it might be less expensive than international roaming, if applicable.
• All minutes in a monthly plan are exhausted and overage minutes are more expensive than minutes used on a prepaid SIM.
• Separate SIMs for personal/business usage.
• Usage of another SIM while sharing the same phonebook.
• Resale value of the phone is increased as an unlocked phone will cater to the needs of more potential buyers rather than those limited to a certain carrier. Check various auction sites to confirm this.
• You don't need to purchase another phone when you are switching phone companies.
• Allows you to switch phones easily between friends, family and colleagues.
• Freedom to change and more options are always better than less.
