The service now works fine. My data package is 2000 MB for under $25----reasonable. GPS doesn't use that much---primary reason for me.

I wish everyone could instruct over the phone in this manner as so much easier to understand. I feel he made extra effort to make sure I understood and could make the right decision.

Five Starts for valuable personalized assistance… 5 stars for the valuable assistance received from Gino over the phone for me and wife. He is very knowledgeable about SIM card functions and phone operations (both android and Apple) and patiently explained everything. He also made useful suggestions about data plans based on our specific travel plans including how to get the best value on the different options. We haven't used the card yet so this review is based and very appreciative by the exceptional customer service we received from Gino. We hope Gino gets an extra company bonus for next Christmas. :-)

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.
