One sim customer service is very good
One sim customer service is very good, no need to wait, just dial from your mobile to customer care, and within one minute you will receive a callback. All problems were listened to very carefully and they were resolved instantly. last 7 years I have been using this service in various countries whenever I travel. No need for a local country number to dial someone.

Hello Gina,
This is probably not the best place to provide Customer Support. Are you suggesting that the device isn't accepting the QR code? The best thing to do is to log a trouble ticket with Support here:
https://www.onesimcard.com/contact-support/
Our support is available from 8-midnight today (Eastern USA Time, UTC-4). If your device is eSIM capable and it is unlocked by your service provider back home, I am certain we can help you. When you log your ticket please supply the model of your phone and the version (in the about menu in settings). Also, who your service provider is back home/where you bought the phone.
Regards,
OneSimCard
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. :-)

Had some ordering kinks but got the phone and I'm using it to text this in Switzerland.
I was hoping to get the phone just a little sooner, and also, I tried ordering it for two days and kept getting an error message so the buying experience had some kinks to deal with. This is, however, my second phone from OneSimCard and like the service very much.

Not User Friendly and hard to get help
First, the initial set-up was very confusing for someone who is not at all "techie." In addition, when I finally got hold of someone from tech support, I was told that there was no way to test my phone while I was still in the US and that I would have to wait until I got to Ireland.
My worst fears were realized in not having things worked out ahead of time because when I arrived in Ireland my phone would not send or receive calls or texts. I tried to reach tech support 5 different times, but just got placed on hold. Being with a large tour group, I did not have the time to wait on hold for a long time.
So I went 5 days of my 10-day vacation without the use of a phone. Finally, by multiple attempts at various solutions on my own, I stumbled on typing the "00" before the 1+ when I dialed. The tech support agent I had spoken with before I left had told me to just make sure I dialed the 1+. Such a simple fix...sure wish I would have known.
I would not recommend this card to others unless they were very tech savvy. It is not for someone like me who doesn't really understand how these things work, and the help is not readily available.

Hello Pauline,
Thank you for the review. We understand how frustrating technology is when it doesn't operate the way we expect it. Roaming international SIM cards can be tricky and we are always happy to help and take our time to explain things in full detail. We would like to explain in further detail how your expectations weren't met properly if that will help:
1) You were hoping to try the SIM before you left but you couldn't place calls from/to the SIM card while in the USA. This is true. The "big 3" cellular networks in the USA (AT&T, T-Mobile, and Verizon) have "sunsetted" their 2G and 3G networks over the last year or so. Cellular voice used to be carried on these networks, but now voice is being broadcast using "VoLTE" (Voice over LTE) which uses the 4G network for voice. Our roaming service does not have the ability to use VoLTE and for this reason, voice will not work in the USA. We were very happy to see you used voice with no issue while you were abroad, just as our Customer Service agent indicated. If you would like to learn more about the problems with VoLTE roaming in the USA, please visit:
https://www.capacitymedia.com/article/2a5x2tyoz25np4z7yz1fk/news/roaming-goes-down-the-drain-as-at-t-disconnects-european-travellers
This article explains the situation quite well.
2) We are so very sorry that you also had difficulty understanding how to make an international call. Any time you call an international number from any cell phone you should always use either "00" or the "+" sign before the number you are calling. This is true using any SIM card, or any service. For example if you want to call a friend of your in England from your USA cell phone, you would dial 0044, or +44 and then the rest of the #. The reason why 44 is this is the country code for the UK. In your example, to dial back to the USA from Ireland, you would dial 001 or +1 and then the rest of the number because the country code for the USA is 1. We not certain what the Customer Service agent told you because this was over the phone and not a support ticket with exact documentation. We train our agents to tell customers about the + or 00 when they are asked. Is it possible they told you to use the +1 but you assumed they mean 1+? In any circumstance, we are very sorry for the confusion and we are making doubly certain we are clear in our instructions to our customers
Again, thank you for your rating and explanation of your experience(s) with OneSimCard. We are very sorry you got frustrated and we hope you accept our sincere apologies for any confusion caused! We hope you had a a fantastic time with the group in Ireland!
Regards,
OneSimCard

Hello Robert,
Thank you for your review. We are very sorry for your negative experience and your frustration. It can be extremely aggravating when technology doesn't work the way we expect it.
We investigated your specific issue with voice service not operating in the USA. When we looked at your account detail, data and SMS was working fine all along and, based on your tickets with customer service, this was only an issue where the Voice service didn't meet your expectations.
This is a problem, not with our service, but with how the major USA networks "sunsetted" their 2G and 3G networks over the last year or so which used to broadcast voice. These networks (AT&T, T-Mobile, & Verizon) now use what's called VoLTE (Voice over LTE) to broadcast voice. Our roaming SIM isn't capable of using VoLTE. Our work-around is to use our 1SIM VoIP App, which we suggested on the trouble tickets, and actually lowers the cost of making calls vs. using traditional roaming Voice calls. Please visit this site for more information:
https://www.onesimcard.com/voip/
1SIM VoIP is available on Google Play and the Apple App Store.
The sunsetting of these networks and the switch to VoLTE for Voice calls is a huge problem for all roaming services, not just ours. Please look at this article for more information about this issue:
https://www.capacitymedia.com/article/2a5x2tyoz25np4z7yz1fk/news/roaming-goes-down-the-drain-as-at-t-disconnects-european-travellers
We understand that the explanation of the problem doesn't make your frustration go away. We only hope that you now better understand the problem of Voice in the USA. It is only available with VoLTE and the problem is not with our service, the problem is how the USA carriers hurt the industry. We hope you look into using the 1SIM VoIP app or other VoIP apps like Telegram, WhatsApp, Facetime, etc. to make calls when you are in the USA using our card.
Regards,

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.

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.

I was given instructions on how to test my sim using more than one unlocked phone. They never resolved the problem of finding the cause of no signal. I had to speculate that I had a damaged sim and ordered a new one. They said I could transfer the balance from the old sim to the new one.

Thank you for your review. We are very sorry your experience was anything less than a 5-star one and we hear your frustration. It can be extremely aggravating when technology doesn't work the way we expect it.
We investigated your specific issue and we think it has to do with voice service not operating in the USA. Is that correct? When we looked at your account detail, data and SMS was working fine all along. Based on your tickets with customer service, you talk about the SIMs "not connecting, but in deep investigation this was only an issue where the Voice service wasn't connecting, correct?
This is a problem, not with our service, but with how the major USA networks "sunsetted" their 2G and 3G networks over the last year or so which used to broadcast voice.

1SIM VoIP is available on Google Play and the Apple App Store. You mention you are using old "flip phones" with our SIMs. To use the VoIP app, you will need an iOS or Android handset.
The sunsetting of these networks and the switch to VoLTE for Voice calls is a huge problem for all roaming services, not just ours. Please look at this article for more information about this issue:

We understand that the explanation of the problem doesn't make your frustration go away. We only hope that you now better understand the problem of Voice in the USA. It is only available with VoLTE and the problem is not with our service, the problem is how the USA carriers hurt the industry.
We hope you look into using the 1SIM VoIP app or other VoIP apps like Telegram, WhatsApp, Facetime, etc. to make calls when you are in the USA using our card.

SMS for Bank verifications has been down for days
It worked well for a while, but it's been several days that they had issues with SMS for Bank verifications, no updates, nothing. Customer service has no updates, they won't answer on social networks either.

Antwoord van OneSimCard
Hello Andrea,
Thank you for the review. We understand that this service outage is frustrating. We have been providing this service for over 4 years and this is the first issue we're having with it.
The current outage is beyond our control and all of our customers that don't want to wait for us to fix the service have been offered a refund.
Please feel free to write into our support if you need a refund or would like help of any kind. We apologize for this service currently being down and any frustration this has caused. Unfortunately the problem is not in our control and if we don't get updates, then we can't provide updates.
Again, thank you for the review, we are sorry that our service didn't measure up.
