I talked with Gino about the problems I was having with my DataMax Sim. He was wonderful. He walked me through what I needed to do with my new phone and my OneSim account, step by step to ensure it was working properly. He even helped test it out while we were talking. He was incredibly patient as well as very, very personable. I can't say enough about how great he was and how much I appreciate his help. I would never hesitate to call customer/tech support in the future with any problem/issue that arises with OneSim. Thanks so much Gino and OneSim.

I have had a OneSimCard account for many years.
Bought my first phone thru them and my second also when the 3G was going away. I needed a better phone for some upcoming trips. The phone I wanted was no longer available from OneCardSim so I found a similar one online. I tried to get my SimCard to work, but no luck. I called OneSimCard and Gino spent quite some time and helped me verify that it was locked. Had to return the phone.
Gino called the next evening to check on my progress with getting a new phone.
I eventually found another and with his directions I was able to get it to work. He also gave me some great advice on what to look for in a cellphone that would do what I needed it for.
Can't say enough about the support and effort that Gino gave me. OneSimCard gets my five stars for going above and beyond to help it's customers.
I am sticking with them...
Thanks Again

Jino or Gino spent much time with me very patiently and helped me get set up for using OneSim on my next trip and probably many in the future. He was very kind, thoughtful and thorough. I should have no problems. He is the best customer service person I have spoken with in ages, maybe ever.

Antwoord van OneSimCard
Many thanks to Jino for outstanding customer service and help

THANKS

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...

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

Thank you to the customer service folks David and Andrew - good information and details on what is the correct sim card for my trip. Thanks also for expediting shipping. Well done OneSimCard.

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.

After an exhaustive month or so on a OneSim Help Desk Ticket trying to determine why my VOIP app did not work on an Android phone, I congratulate the help team for putting up with me. It is not that I don’t like OneSim; I do and have used it for over ten years with great success. When tech things go wrong, I suspect I am not alone in becoming a poor-me bore and a nuisance. Although One Sim did not actually solve my problem, they spent endless time with me trying many solutions. In the end, changing the modem/router in the house had OneSim’s VOIP app working perfectly.
In an age where so much of customer service is robotic at best and non-existence at worst, it is great to know that OneSim has real people to keep customers happy and up to tech speed. Thanks guys.

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.

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.

Extremely fast follow up on questions. When my sim card was held up in USPS, they contacted them and I received my card the same day.

Wanted a sim card that delivers. It has not got a out of country limit to the days.
Although I live in England it covers all the country's I visit as a truck driver and traveller.
I have not used it yet.

Antwoord van OneSimCard
well, I've not received the sim card yet, but so far, the service has been easy, when i went to your customer support team, the response was quick and informative, so yes i can say my experience with you has been great and easy.

After conducting extensive research for a reliable phone service while traveling internationally, we chose OneSim Card and couldn't be happier. We started the service 7-8 years ago with hard SIM cards. This year. I decided to try their eSIM in one of our phones. Customer service provided by Gino was "Top Notch" in resolving a couple of issues in a timely fashion. Gino stayed in contract throughout the process, ensuring all technical issues were resolved to our full satisfaction. We're installing their eSIM on my wife's phone now as well after piloting on my phone. The eSIMs will reduce the number of phones we have to carry for travel for safety and communication purposes. We highly recommend OneSim Card!!!

Ho comprato questa sim perché pensavo che ci fossero degli abbonamenti dati non soggetti a limiti di tempo. C’è infatti sul loro sito un menù a tendina con tutti gli abbonamenti disponibili con scritto vicino il tempo di rinnovo (es. 30 giorni). Tuttavia ci sono delle opzioni dove i tempi di rinnovo non compaiono lasciando pensare che non siano vincolati al rinnovo invece non è così.

I regret to share an extremely disappointing experience with OneSimCard's support and service. As a customer who relies on their SMS service for essential 2FA (Two-Factor Authentication) access to my bank account, I have encountered a severe disruption that has persisted for over 15 days. (We are not able to get sms since 1st november)
The inability to receive authentication messages from my bank has effectively blocked my financial operations and caused significant inconvenience. This disruption, which directly impacts my access to vital banking services, has had dire consequences for my ability to manage financial transactions.
And there is inadequate response from OneSimCard's support team. Initially, they attributed the issue to the Bank of America, which led to unnecessary delays in addressing the problem. It was only after further investigation that we discovered the complete failure of PEN numbers, which is integral to the service.
This experience has not only eroded my trust in OneSimCard but has also raised serious concerns about the reliability and competence of their support and services. As a customer who values dependable and efficient service, this ordeal has been deeply frustrating and has caused undue stress.
I hope this review serves as a cautionary tale for others considering OneSimCard's services. The inability to provide essential services such as reliable SMS delivery for 2FA has left me extremely dissatisfied and seeking alternatives that prioritize customer satisfaction and service quality.
In light of this experience, I would strongly advise potential customers to explore other options and exercise caution when relying on OneSimCard for critical services.

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.
