Happy Ending After an exhaustive month or so on a OneSim Help Desk Ticket trying to determine why my VOIP app did not work on an Android phone, I congratulate the help team for putting up with me. It is not that I don’t like OneSim; I do and have used it for over ten years with great success. When tech things go wrong, I suspect I am not alone in becoming a poor-me bore and a nuisance. Although One Sim did not actually solve my problem, they spent endless time with me trying many solutions. In the end, changing the modem/router in the house had OneSim’s VOIP app working perfectly. In an age where so much of customer service is robotic at best and non-existence at worst, it is great to know that OneSim has real people to keep customers happy and up to tech speed. Thanks guys.

Service Down: Incompetent Response (No Response) I am 70 years old. I use 2FA for this company to access a bank account to transfer funds for a medical emergency. OneSimCard service has been DOWN for two days for 2FA banking. Stuff breaks and that can be excused. What cannot be excused is the poor (non-existent) customer service. No response on phone calls. No response on Live Chat. Warning to potential customers: STAY AWAY FROM THIS COMPANY. Any company that cannot keep lines of communication open when stuff breaks does not deserve your business. It's a DAMN GOOD THING I DON'T HAVE A MEDICAL EMERGENCY AT THIS TIME.

One sim customer service is very good One sim customer service is very good, no need to wait, just dial from your mobile to customer care, and within one minute you will receive a callback. All problems were listened to very carefully and they were resolved instantly. last 7 years I have been using this service in various countries whenever I travel. No need for a local country number to dial someone.

Ripp-off - not supported by German Network Providers 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.

HIGHLY Recommend OneSim Card After conducting extensive research for a reliable phone service while traveling internationally, we chose OneSim Card and couldn't be happier. We started the service 7-8 years ago with hard SIM cards. This year. I decided to try their eSIM in one of our phones. Customer service provided by Gino was "Top Notch" in resolving a couple of issues in a timely fashion. Gino stayed in contract throughout the process, ensuring all technical issues were resolved to our full satisfaction. We're installing their eSIM on my wife's phone now as well after piloting on my phone. The eSIMs will reduce the number of phones we have to carry for travel for safety and communication purposes. We highly recommend OneSim Card!!!
