Just make sure if you buy off eBay or Craigslist that the phone you buy is either specifically for your carrier or unlocked. If you buy a Sprint phone that's not been unlocked for example and try to activate it on Verizon you will not be able to. That's because the unlocked Sprint phone would be locked to that carrier.
Most reputable sellers do unlock the phones, but just make sure it either says "Verizon" or "Unlocked" in the listing.
Really? I thought that an unlocked phone can be used on a different carrier only if they used the same technology for their phones. That would open up a ton of options if that were true, and I'll be kicking myself for purchasing the phone I did when I could have used another.
