Poor Service Poor Service As much as I would like OneSim to work, the fact is that it is a failed operation. I am abroad and needed a number for my bank to contact me. I found OneSim and had to sign up for an annual subscription (already a telling indicator that I had to sign up for 12 months as a minimum). The service is unreliable and when I contacted customer representatives, they told me that they knew that there was an issue but were unable to provide any repair date. Overall, this feels like a scam.

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.

Expensive choice that works in East Africa but did not work well in the USA This card may be useful if you travel a lot, but it is way cheaper to buy a local card. I got one to travel in Africa and to use in the USA. The coverage in East Africa was fine, but it was very expensive to run. The coverage in the USA was unreliable and cost was so high that I bought a local pre-pay card for much less. They give no refunds on extra credit if you top-up in case you need it. My purchase of this card ended up being an expensive experiment that was rarely worth it.

Bad. Very Bad service Bad – unacceptable experience, unreasonable and rude conduct. I paid in Fry's $19.99 + tax. For foreign phone numbers + one month registration (with zero balance) they charge additional $39.99. ??? Any one need such service? Can you get refund? No because you will know about your ZERO BALANCE and all additional fees just after you register online. Bad. Very Bad.
