"I just wanted to tell you how great it was to travel with OneSimCard. We had to be in the UK, Ireland, Poland, Greece, Cyprus and South Korea. It worked so well everywhere - NO problems! Thanks!"
Colleen B., CA USA

"Amazing personalized service. I used to be with a competitor and I won't be going back, as OneSimCard is a better deal and with better service."
Ernie C., ON Canada

"I just received the global SIM card I ordered a couple days ago. Due to my lack of familiarity with using the international cell phone I bought to be used with the SIM card, I encountered errors making test calls and text messages. When I called OneSimCard's customer service number, they patiently tested the functions with me. Not only were they prompt about shipping the SIM card, they deliver excellent customer service and support. Furthermore, I have not seen any hidden charges. I strongly recommend anyone needing a global SIM card to use OneSimCard."
Carissa B., MA USA

"I am really impressed with OneSimCard cell phone service. I used it with my old unlocked Motorola V3 phone in 4 countries - Italy, France, China and Hong Kong. It worked everywhere without a glitch and saved me at least $400 in two weeks that I was traveling abroad."
Bill B., MA USA

"I found OneSimCard to be most reliable and economical. I plan on using OneSimCard frequently and I just wish I had discovered them sooner."
