Whenever you are in the market to purchase a phone, you have a choice: do you buy an unlocked phone or a locked phone?
The answer is simple: Always go with an unlocked phone. Unlocked phones are better for several reasons:
They are usually less expensive than a locked phone. Locked phones are typically sold by carriers (i.e. AT&T, Verizon etc) and they sell them for significantly more than what you'll find at Wireless Place.
Unlocked phones can be used on almost any carrier anywhere in the world. You can take your phone with you when you travel abroad and just insert your SIM card into your unlocked phone. Begin using your phone via text, calls, data.
Flexibility to switch carriers. If you find out that a phone carrier is going to give you a better price than the current carrier you're using, go ahead and switch. Simply insert the new SIM card into your unlocked phone and begin using it.
