I got OneSimCard Universal in FEB 2023 & I'm one happy customer ! I'm an Australian who travelled to Singapore, Malaysia & California,USA using OneSimCard. I was apprehensive at first that I could use just one SIM card for three countries & more. I had no problems whatsoever throughout my 21-day trip as I read thoroughly the user-friendly operational manual available on their website. I simply opted for the Zone A Data Plan which cost $20 for 30 days with 1000 MB which was more than sufficient. I used only WhatsApp when making calls because I could use home wifi when staying with relatives & turned on Mobile Data & Data Roaming when I was outside. I had no problem using Uber & other ride share apps which required only mobile data which I had plenty using Zone A Data Plan. I found using WhatsApp with Data was a cheaper option than making regular voice calls. I made sure I switched off both Mobile Data & Data Roaming when not in use to prevent data wastage. As such, I still had about 500 MB data leftover from the 1000 MB ! Perhaps those who complain about this mobile service should look into this. Although I'm not very tech savvy, I must thank Gino from OneSimCard Support team for patiently answering all my questions so I can make an informed decision on which SIM card to choose for my requirements. My many questions were swiftly replied via email & also by phone in record time. His replies were clear, targeted & precise which ultimately resulted in clarifying my doubts. I made my purchase confident that I can rely on efficient customer care should I ever need it. So yes, I would highly recommend OneSimCard for seamless mobile phone coverage when travelling.

Very concise assistance.

German network providers do NOT support this Simcard. On the website they claim that they cover Garmany but I am from Germany and it doesn't work - their support confirmed that their simcards are not coverd by German network providers. This might affect other European countries as well since e.g. the simcard is not working for telecom. Now I want my money back bcs. they make false claims on their website and it is not working for me in Germany but the support is not responding to my mails. Additional they are very expensive compared to other providers. Look for other providers!! Especially when you want to travel in Europe or if you have family/friends in Europe.

Easy set up and free incoming calls in north america and australia. An excellent sim to stay connected. Good service even live agent chat available for some supporr and answer questions.

responded quickly to my question....

They are nothing but a scam. I bought an e-sim from them as I am going to be travelling internationally. When I installed the SIM in my device it would not get any service. I called a customer service who had me do a lot of things, including erasing the SIM and then reinstalling, but none of them worked. Later he tells me he will escalate the situation and then I receive and email saying I have to activate my data pack to get service. Since I had time, I decided to only activate the data right before my travel and after activating I still did not get any service. When I contacted the customer service again, they had me do a bunch of stuff again and finally at the end they say you cannot erase and reinstall an e-sim and so I cannot use that SIM anymore. I would have to buy another one just to use it. Keep in mind that when I reached out to them, I told them what are the things I tried, including reinstalling the sim. They however only decided to let me know that my SIM would not work after wasting my whole day going back and forth, telling me to trying different things. Therefore, it is quite clear that they do not know what they are doing and so making up an excuse just to get even more money out of me.

My iPhone with OneSimCard and has been used worldwide for a few years now. It has worked flawlessly and was especially appreciated while traveling during COVID times. Customer service has been excellent.

I really was looking forward to using this eSim product as it would have solved a few problems for me, however this is the most expensive and confusing option for any travel data needs. The data plans are at least FOUR times the cost of a travel SIM purchased locally. The plans themselves are very opaque and need to be simplified dramatically to service the needs of all customers. I submitted a support ticket (Ticket 266679 for the OneSIM people monitoring this site) which was initially promptly responded to, but I still haven't received a response to a clarification question. This product has so much potential, but the delivery of the product is confusing (probably deliberately so), very expensive and certainly not worth the money. Don't get me started on the confusing website and the atrocious android app to manage your account with. The app freezes on both of my Google Pixel 7's and is unusable.
