This card meets a very important and specific need for international travelers. Most importantly, it eliminates the need to pick up SIM cards in every country you visit which is a real benefit given the frequent bureaucracy and language barriers that can hinder the process. And with the appropriate apps (downloaded free) the cost savings can be substantial. I'm new to this system and will be testing it thoroughly in the months ahead.

I like a lot of the company. I'm able to get a free sim from other country where people from there can call me free of charge. Too bed it's expensive at early, but in long time it's a good solution. And there PEN it was only landline phone, I would prefer mobile phone PEN also.

Just getting started with OneSimCard, but the experience so far has been excellent. Ordering and delivery went smoothly and setup for test call was easy. The rates seem fair and I like the idea that the card remains active during extended periods of inactivity. Looking forward to using it in multiple countries soon.

Excellent service, timely responses and good website. I needed the ability to call from different countries and to receive calls from the US when out of the country and OneSim is the best solution I could find. Prices very reasonable, and setup was a breeze.

Travelling without an immediate means to connect with family and friends was a nightmare. With onesimcard, life has become seamless and I am enjoying every moment with onesimcard. Keep up the good job!

I have been very happy with the service I have received from Onesimcard. I first purchased a phone from them almost a year ago and used it without any problems while I visited relatives in Europe. I am now planning to return to Europe for another visit. Since I hadn't used the phone since my last trip, I used Onesimcard's online chat support service to help me get the phone set up again. I had a very helpful and pleasant session with Stephanie, one of their representatives and now I am ready to start using the phone again.
