I have been traveling overseas for more than 5 years, now taking part in pilgrimages to many different countries, and up until 2 years ago keeping in contact with family and friends while in foreign countries was difficult and very costly! I stumbled across the site online for OneSim Card nearly 2 years ago. This was my second year in using their services and I will continue to use OneSim Card each and every time I travel. The rates are excellent and the customer service is second to none. There are many options which allows one to customize and purchase the Sim card that suits your needs. The number of countries available is impressive!. I would never travel abroad using my cell phone now without purchasing a OneSim card plan. Thank you OneSim Card Services for the great service!

I have been using OneSimCard for my international travels for over four years. Having the assurance of being able to call from anywhere or to have others call me for a very reasonable cost per minute is great. I have used this sim card on 3 continents in more countries than I can count. It's always ready. The small additional cost of having a local (USA) number for family and friends to call toll free while I am abraod is icing on the cake. Great service from these folks and an easy website to manage your account.
