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.

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. :-)

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.

I was very impressed with the support… I was very impressed with the support from OneSimCard. I did a lot of research before purchasing since this was my first International trip. I saw good reviews for so I went with this one. I contacted them 3 times before the trip and they were very responsive and helpful. Once I was on my trip, I had a couple of issues and again, their response was swift and professional. The installation was easy enough and since we went to two different countries, it was nice to not have to get two different SIMcards. It worked in both countries. Thank you.

Gino had excellent patience with me and… Gino had excellent patience with me and was very clear and spoke slowly so that I could follow him. 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.
