Very convenient, price is great.
I used OneSimCard second time on my trip to Mexico. Connection is great, my tenants have no idea that I am out of country. Bill was less then half of what it would be with my AT&T.

I have used Onesimcard service for over a year now. I have travelled to various countries and regions. I have found the service always reliable. When I contact customer service for questions or such, they are helpful. I am satisfied with the service that I recently purchased one for my wife. Thank you Onesimecard for the money I have saved in not paying roaming fees from my local carrier. Eugene E

A convenient and very reasonably priced way to keep in touch with home. I have used it to receive calls from the US in many countries, and the price is a predictable 20 cents per minute. I transfer calls from my cell or home phone to the local US number, and my clients don’t even realize that I am out of the country.

I am giving OneSimCard 5 stars for working in over 13 countries I traveled to and never letting me down. It saved me a bunch and it is the best roaming SIM i ever tried.

I recently traveled around Italy for a few weeks I bought a ski card from Onesimcard. It worked great, I had tried one of these before with little success. This time i put the sim card in my older iPhone and never had a problem with phone calls and texting. The cost per minute are very reasonable compared with bring a US phone there.

I bought the OneSim Card for my trip around the world earlier this year. It helped me keep in touch with family and friends where ever I was and gave then the opportuntiy to call me on my US local number.

Buying the phone and loading minutes on line was easy, even for a couple of old codgers. And using the phone was as clear and easy as our phones at home. We are really excited to have easy connections when traveling overseas. Yeah! Michael & Sharon Sugar Land Texas
