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.

Worked for a while and then became a… Worked for a while and then became a problem, who this day an age requires a form to be filled i with your credit card details - for a payment? Sounds like a phishing technique. Not for me...

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.

ACTIVATION A bit of trouble activating - my own lack of experience - I did not include the oo before the number to use to confirm activation. Called the help number & spoke with Brian - quickly sorted me out

Unreliable Service As a long time customer, OneSimCard has provided marginal service for many years. It is definitely not what a cell phone user needs. When their service stops working properly - - you report the problem to them, and they give you a run around at fixing it. All of a sudden, their service magically starts working saying it's not their problem. Users should not have to put up with this kind of response. Users need reliable service. Don't use OneSimCard, Ken
