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

I am giving 5 stars because the… I am giving 5 stars simply because the customer service agents stuck by me for two long trouble shooting sessions when in the end, I discovered that it was MY problem because I had "Do not disturb" clicked on my phone resulting in voice calls not connecting. 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.

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.

I gave 5 stars for the help we received from Gino I gave 5 stars for the help we received from Gino over the phone. He was very knowledgeable about how the SIM card functions and explained everything well. He made suggestions about data plans based on our specific circumstance and told us about how to get the most savings for texting etc. We haven't used the card yet so this 5 star review is only based on the great customer service that we received from Gino. Thanks!

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.
