Thanks to Gino for his excellent support! After several fruitless days of emails back and forth to different OneSim support folks to get my voice calls working, it was Gino who very patiently did extensive trouble shooting and discovered the solution - now I can call out and receive calls using the 1SIM Voip app. And he clearly explained how to use either the Internet or SIM data, and how to set up my Samsung to minimize background data costs from all the other apps. Being able to speak with him on my landline while he was troubleshooting was key.

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.

Excellent customer service Thank you to the customer service folks David and Andrew - good information and details on what is the correct sim card for my trip. Thanks also for expediting shipping. Well done OneSimCard.

Can't Use Visa or PayPal I have used OneSim for a couple of years. Since day one I have not been able to use my credit cards (RBC Visa and Mastercard in Canada) to buy credits on the Sim account or even buy credits in the 1Simfund. So I have been using Paypal to make payments on their system. However it appears that they are no longer allowing Paypal so it's adios to OneSim. I've never had such a frustrating experience trying to give money to a vendor. UPDATE. After this review OneSim sent me an email explaining that my account information must match exactly what is input on their order system. I have spent hours with my bank trying to correct this and nothing works. I have not had this issue with other vendors in over 30 years of using my Visa cards. Very disappointed.

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.
