OneSimCard - www.onesimcard.com

This international card allows the European, and others, traveller to receive calls and texts while outside their own countries at a reasonable rate - free. And, although the sender foots the bill, onesimcard has options to assist those communicating with him/her whilst travelling away from the feeling of safety felt in the home country. All the traveller needs is an unlocked GSM mobile phone to start the experience of connectedness whilst abroad. I have yet to experience its full practicality, but am confident it will come up to my expectations.

Very confusing. I thought I was getting a cheap data plan but no, didn't work in the countries listed. There was another list that applied. So I ended up paying $0.25 per MB over $140 for a 2 week trip. And coverage was poor. At one point it just stopped working. Had to call tech support to get data working again.

I purchased two One-SimCards (data, phone/data -- for $85 including processing) for use in Europe (Denmark) about 1 month prior to my trip. I tried to use in the USA and after one week of harrowing experience I got it to work through a rather convoluted mechanism (difficult to describe here). In Denmark, the approach simply didn't work. Instead I purchased a sim card from 7-Eleven and within 3 minutes my unlocked phone was up and running. I paid about $45 for 100 minutes or so and 35 GB of data. Since I could call Vonage over data, the minutes didn't bother me. Now I don't know what to do with the useless One SimCard. My best advice is, wait till you get to your destination and purchase the phone service locally -- this gives you the least amount of headache for the cheapest price.

They charge for minutes which never rang the calling number and claim the call was legit

KEEP AWAY this is a COMPLETE SHAM

Their customer service is overconfident with the quality of this phone. And you will have to trust the verdict of their so-called honest technicians. And if they say that it's not their fault, then you lose postage costs, time and your nerves. No guarantees and reassurances whatsoever.

I do not really trust this company.

If you get an extra phone number to use with wifi connecting it does not work properly

I purchased the card for my wife to use in Taiwan. I spent hours setting it up on her phone, studying international dialing formats. The card didn't work. I contacted customer service and they said things along the lines of "we show you are connected to a network - maybe try this dialing technique, or this...etc." Never worked. Wasted $75. They wouldn't refund a dime. When I called the customer service rep to try to reach a compromise, he said that since the card was used (about $2 of the $50)...my wife was able to make an international call to the U.S. from Taiwan, but unable to make or receive local calls in Taiwan)...no refund would be provided. I told him politely that I was dissatisfied with his unwillingness to negotiate. He (Yuri) hung up on me and then refused to answer my calls.

I would give no stars if possible. I bought 2 OneSim cards before lraving for 3 week trup to Europe. Spend 1.5 hours on with customer support in the first country we visited. Finally got them to work. Now, in another country, can't send texts or email. I've been screamed at and hung up on by OneSim customer support. OneSim refuses to address the problem. It sayin it's not their problem because it appears it doesn't know why we're having this problem.

Unless you spend more than $25 per year using a one sim card, I strongly suggest that you do not sign up for one.

We travel overseas 4 or more times per year and signed up for twos one sim cards for our overseas cell phones.

Even though, I cannot find the fine print where they said that I would have to renew at $25 per year. even if I still had a lot left over from the previous year.

There was no way we could spend $25 per year, $50 for our two cards and so the balance kept building up until we have over $100 in each card and there was no way to get the money refunded. So we lost over $200 when we didn’t renew this year.

Avoid this card unless you spend over $25 per year per card.

We were reassured by this company before we bought the cards in the USA that they were compatible with our cell phones. I got information for shutting off our phones at the airport as we were leaving the country, which I did successfully. When I tried to activate the SIM cards from ONE SIM CARD in Europe they DID NOT WORK. Their product information said to watch videos to learn how to load them. I was in Europe with no PC on which to watch videos. I asked for assistance and got none. My techie nephew was unable to make them work. I wasted $86 on SIM CARDS I could not use on our European trip. Because we were gone one month we were not able to connect to ONE SIM CARD untill we returned home, and were then told we were out of the policy time span for any refunds. I felt his very unfair and will not recommend anyone to buy from this company. All I got was "I'm sorry you feel this way!" How was I supposed to feel when I bought something in good faith that did not work and I was then without a phone when one would have been very helpful in many instances in Europe?

I will not do business with ONESIMCARD again. Totally disappointed in their product and service.
