skype for travelers

Skype has a great service for worldwide travelers. When i decided to travel down to South America, my parents couldnt use skype because they dont have a computer. Skype has a telephone service i use with my Nexus 7 tablet. It gave me a local number where i live in California, and it enables my parents to call me anywhere I am just making a local call. I can also call anyone anywhere. So far it has cost me less than $8.00 a month, a low price to pay for my moms peace of mind!
