My sister was taking care of my children while my husband and I were away on vacation.  We bought a new phone last week after looking at different GSM Cell Phones.  The phone we chose was really nice as it had many different capabilities, including Internet.  It was nice that I could talk to my children as this phone was able to work in the country we traveled to.  Not all cell phones work this way.  My husband and I are planning more trips overseas, and it is nice we have a phone that will work wherever we go.  We will always be able to check up on our children.
