Don't take Onesimcard,
On Iphone, their app doesn't ring if your phone isn't unlocked and the app isn't open. So it's completely useless. What's more, no alert appears when I don't pick up calls. When I call Europe, instead of my U.S. number appearing on my correspondent's display, there's a French number! Response from technical support: it will take more than a day to solve this problem. I'm still waiting for my number to be displayed correctly after a week. Reply from the app: I've reinstalled our app.
I have reinstalled their app 5 times on iPhone, without success.
Refund request in progress.
REPLY : I tested 5 numbers in Europe and all of them has the same issue with a french number instead my US number appearing. Didn't have the time to send you a request for refund now. Will do it tomorrow for sure.

Fast turn-around on eSim order.
Good instructions on set up.
OneSim is working on a problem for a difference for the balance of the account on the phone app vs the web app.

Being able to talk to a live person made it possible for me to load eSIM on my phone. The “live chat” was too slow to be helpful and some incorrect information was provided (IMO). I think the written instructions on the website need a thorough revision for clarity. I bet it would improve your bottom line by encouraging more people to sign up.

Chat help was very informative and knowledgeable. Made it easy to determine which one to get. Lots of affordable choices.

UPDATE: I GOT A REFUND. To thank you, I changed my rate from 1 star to 2 star, and the review title from "Fraud" to "Fraud (Update: not a fraud)". I never got an email though. I hope you develop better support operations. My Original review follows...
Never received the sim. Never got an answer back. This is what I was expecting, but I decided to try and check it myself.

Antwoord van OneSimCard
They are advertising products they don't have (which they admit to!) such as US based numbers, and two-factor services for banks etc.
These are clearly listed on their website as services they offer!!!
Extremely unprofessional company!

Antwoord van OneSimCard
Their business model is based on fraud. I bought their e Sim and have around $125 in my account with them. When it was time to use the service, it simply did not work. I contacted their customer service and was presented with some "solutions" but nothing worked. I had to buy another Sim from another service provider. I am asking for my money back but One Sim was first stalling me and now their CS is not responding. Clearly they are thieves and robbers. STAY AWAY FROM ONE SIM CARD.
Update: I am responding to One Sim's reply to my review.
I followed each and every step suggested by your technical support not just once, but several times. You should have access to the exchange of messages, or should I post the conversation here so that potential customers can judge how you are trying to mislead. Shame on you.

Well organized and informative web site. Follow up to confirm I really intended to order more than one sim card. Which I did.

Antwoord van OneSimCard
Very happy with these e-sims especially the DataMax eSim!

Again here in Costa Rica, great connection with my normal numbers set as + 1 yyy xxxx.
It's a callback system that works fine. Ken

Very easy to use service if you travel abroad and don’t want to look for a free wifi or pay huge roaming fees for data. I’m a fan 👍

It is very easy and straightforward to choose a sim and send it abroad.

Product itself pretty valid with good network connection and a pretty stable line.
Prices overall fair and on some items even cheap.
Excellent customer service: highly responsive and attentive.

They answered my questions in a timely manner.

Swift and easy service made the company great. I didn't have any single problem ordering the sim card. Further more, it was very smoothly completed. Thank you very much for your quick and efficient services. All the very best OneSimCard.

Gino was excellent at addressing my issue and providing me with clear options. It is refreshing to find Customer Service that actually provides the customer with service. Thank you

Antwoord van OneSimCard
Gino was extremely patient with an old school tech challenged person, me. Spent alot of time helping me set up the esim on my Iphone, then walked me through the app and how to use it. Very friendly, patient and cheerful. A pleasure to work with.
Thanks Gino
