OneSimCard Reviews 

You'll realize you made a horrible mistake once you load the nonrefundable account with money and begin to sort through the various plans which, at the time I did this admittedly a couple years ago, was a nightmare. I would suggest buying SIM cards when you land - it's easy, cheaper and you know you'll get it right. I suggested to OneSim that they let customers submit a travel schedule (my son went through like 10 countries) and then they could develop a plan for appropriate SIM cards. But, as you'll find out if you purchase this godawful service, you can spend hours getting through, talking to customer service, trying to parse plans and really still have a big question mark. In the end, OneSIM kept my $290 remaining dollars in my account and I had no choice but to part ways - then I found out using them wasn't even necessary.

It's not holding up to what the website says. I e tried to send a sms text from bank and it came back as unverifiable.

Exactly what I needed! Excellent!!

Product as describe. Excellent customer service

Extremely good experience

I was very happy with the service, which was prompt and professional.

I don't want to sound "pompous" (if that's the right word), but a lot of average users of overseas/worldwide Sims do not have the experience to work through who is best & the best way to save money on calls, texts, data for internet use & gps navigation.

We live in Australia and our telecommunications companies are super expensive when using an Australian Sim overseas.

Because of this, l have over a number of years, tried many different Sims & the greatest saving comes from buying a local Sim (when you arrive in the overseas country) BUT if that country does not speak or write in English it can get VERY frustrating.

I have been using OnesimCard for about 5 years and it is fantastic. The convenience of using their Call Direct & VoIP apps is really easy and saves a small fortune.

Their customer account website pages are the most "user friendly" I have ever used, and use the Internet a LOT.

I know we all hate spending money or wasting money, but the best way to use OneSim's services is to: Buy a "Universal" Sim / recharge your 1Sim Fund with US$50 to US$100 / Add an ANNUAL PEN with a US phone number (cheapest to buy & better/cheapest data packs).

If you do the above, you will get the greatest savings on an annual basis, then all you do is buy a 14 day or 30 day data pack JUST prior to going on EACH trip.

Then, make sure you follow the "setting up" settings and use the VoIP App all the time. These settings will work in any country in the world so you do not have to mess around when travelling anywhere.

Happy travels.

I chat today with a representative named Jonathan, it was very bad customer service. I simply had a question and was simply trying to understand how their service work. My wife and I had not purchase a card to use, apparently, I used over $100 in service in less than a day my wife didn’t but got a message stating that she need to purchase more service, anyway. I was simply asking questions to understand what had happened this guy straight forward made me felt like I was stupid, was rushing me to stop chatting and Putin writing that had spent 35 minutes with me, even tho I had to wait 20 just to start chatting. The guy who first initial helped meto set up my card on my phone spent almost 50 minutes trying to resolved issue was polite and patient. I’m not satisfied with service I took
Screen shots on the conversation hopefully someone can help this guy understand what customer service it’s about.

The best ever world travel simcard because if you loose or the phone got stolen, you will get your same phone number again unlike any other travel sim cards. And also the rates are very cheap/low in many countries of coverage .
I would like to say onesimcard service is 100% plus.

If I could give 0 stars I would. Terrible customer service!

I. always use my onesimcard.it work great every place I go. I trully recomend getting one. the customer service is really helpfull. thank.you. big 10 for you guys.

I travel a lot across multiple continents, and previously had to maintain a collection of local SIM cards in order to manage my cellphone costs.

With OneSimCard I have no problem keeping in touch with family and business associates while I'm on the road. I have since transitioned all my Viber and WhatsApp accounts permanently to my OneSimCard number.

Worst company ever! Phone never worked and when I asked for a refund, they would not refund in full because they said that I made calls. I was stuck in South Africa without a way to communicate with ANYONE. I would make a phone call (dialed correctly) it would ring once and then a screen would pop up and say that I would get a call back shortly and then tell me my balance. I never got a call back and was never able to successfully make a call. Then, they just charged me another $5 to extend a phone number for another month. Obviously I am not using the simcard because it DOESN'T WORK. I have never dealt with a company as bad as this one.

OneSimCard has been very easy to use from the start. Good phone selection, best prices I've found, benefits and discounts too. Better than Mobal.

I purchased the OneSim Card for my travels while in Europe on a river cruise and for travel in the USA. I had no problems connecting with my phone in any of the countries visited. I was particularly impressed with how well the OneSim VOIP App function worked. This method of calling resulted in significant savings for me over any other method I could have chosen, I basically travelled throughout Europe calling and using internet services for pennies a day.

Recently my wife and I left our jobs and lives for a much needed sabbatical / adventure. We’ve been WWOOF’ing and traveling all around the Mediterranean. But none of this would have been possible without reliable, flexible and affordable cellular service. Thankfully we researched and discovered OneSimCard and their super versatile Universal SIM Card option. We’ve been using this card and their data package all throughout our travels and have been very satisfied with the service. They are quick to respond to tech inquiries and even have a concierge service for travel-related questions. It would have been a pain to get a new SIM card in each country, and with OneSim you never need to do this.

I would definitely recommend this card for anyone looking for a universal, adaptable card.
