Did You Know About Unlocked Cell Phones?

Did you know about unlocked cell phones?

I've not heard of these, but then again, I am pretty much behind the times. I think this is a great idea for folks like my sister who does a lot of traveling in and to several different countries (and she may already have one!)Basically, an unlocked phone allows you to use different GSM-compatible carriers around the world. This would help alleviate lots of phone hassles for folks like my sister.
