I THOUGHT I had checked that this card could be used in Belize. Nope! As a solo female traveler, the inability to use this card put me risk. Customer service not good; they responded quickly but did nothing "because of terms of use" page. Make your site clearer and more CONCISE!

Hello Diane,
Thank you for your review. We know how frustrating it can be when technology doesn't work the way we expect it. We try to design our site:
https://www.onesimcard.com/cell-phone-rates/?view=country/
and more specifically:
https://www.onesimcard.com/rates-and-coverage/?simtype=compare&sourcecountry=BZ
to make it as clear as possible what cards we have work in what countries. We are very sorry you found this information unclear and difficult to follow. We would love to hear from you any suggestions how this can be more clear, so fellow travelers won't have the same problem that you had.
Again, we are so very sorry your experience with OneSimCard was anything other than excellent. We are very open to suggestions and hope to hear from you how we can improve the site.
Safe Travels,
OneSimCard
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!

Love OneSIM
Gotta be honest I’m surprised to see low reviews here. OneSimCard has been a great solution for me. It took ages to find a carrier that offers PEN numbers, which are necessary for 2 factor authentication with banking services. As an expat with assets in the states, this is an invaluable service.
Calls and texts are reasonably priced especially with the VoIP app. You have to buy more minutes for an annual “recharge.” That means I have an ever growing pile of minutes for what essentially is an annual service fee. It makes me stay in closer touch with my family overseas.
The customer support is top notch. Every time I’ve had an issue, support resolved it quickly and gives me plenty of status updates. They’re super friendly and easy to get in touch with. I can reach a human straight away instead of going through several levels of chat bots. I’ve been repeatedly impressed with their service and responsiveness.
I would (and regularly do) recommend this service.

Basic service didn't work at all.
Bought this when I was in Colombia. It never worked. I received one SMS message once from a Colombian number, and that was it. Couldn't received phone calls nor SMS messages from apps for verification. So the basic service didn't work. For it to work with my bank they wanted another $70 per month, and I wasn't going to give them any more $ if the basic service didn't work. Total waste of time and money. When I told them for the second time of the problem they told me I'd have to fund the account again to test it. Nope. What they should have done is fund it themselves enough to test it and make it work. Poor customer service, like so many companies they just don't care.

Hello Lara.
We're sorry to hear you had the trouble you did with our service. Our SIM cards require a balance to work, the SIM needs to have funds on it to work properly.
Our BANK PEN service is a special PEN we sell on the website that is meant to receive short code. Normal PENs will not work for this. You can see this here: https://www.onesimcard.com/local-country-sim-phone-numbers/
Please see our FAQ which will explain everything above in more detail:
https://www.onesimcard.com/faq/
Also please feel free to reach out to our support if you have any further questions or need help with this.
Thank you,

Total rip off of a company
Total rip off of a company. Rip you off on internet, move numbers on your account then say you did. Have guidlines and dont follow them. Avoid.
UPDATE below you can see they tried to blackmail me to remove this review before they'd escalate my issue...
Tip for consumers:
Just terrible customer service
Products used:
Expedition and they rip you off with the internet.
In reference to your replies below-
The first ticket was opened as your underhanded wording of the way the card works uses your credit on the number as well as the purchased data package. That was closed as even though it is a poor and underhanded way of doing things that’s the product.
2- as you can clearly see in the ticket I pointed out that it was a system error that put the credit on the wrong number and I contacted your service center straight away. They blamed me and wanted to charge me for your systems error. During that conversation I’d decided that I’d had enough being treated so poorly by what clearly is an unethical company and posted a review. The agent obviously got a notification of the review and told me to take it down otherwise he wouldn’t help me. I have screen shots of the conversation but unfortunately I can’t post them here on trust pilot but I did over numerous other product review websites.

Hello Ben,
Thank you for your review. I am sorry that you had such a frustrating time with our service. In our investigation we only see 2 tickets created for Support and do not see any "Blackmail" from our agents.
Looking at the tickets that are in the system, we only saw that your questions were answered professionally and promptly. One ticket was from a chat session where you used up your data package and that triggers per MB usage (at a higher effective per MB rate) if there are still funds available on the SIM or automatic recharges. We are sorry that you didn't understand this, but this can't be refunded since cannot control if you are using data. We do have controls available on our site to avoid additional charges and use of data, but you didn't deploy these measures.
The other ticket was your asking for a refund for a service that you bought by accident (seemingly) and that was promptly refunded.
Again, we are very sorry you had such a negative experience. but we cannot understand this "blackmail" you refer to and seem to suggest is included here? Please provide more information so we can investigate further.
UPDATE: Thank you for providing more information. The information you provided does not match your account information or any tickets where "blackmail" was made. We cannot investigate this further without this information.

Hello,
Thank you for your review. We tried to investigate your issue, but we are unable to find your information or support interactions. We would like to understand your situation better. Our SIM cards use a variety of carriers and their services in those countries. Our SIMs are able to use 2G, 3G, 4G and 5G speeds depending on where you are located and what services are available in those locations. The speed of our SIM card has everything to do with where in the world the SIM is located, and the capability of your device in which you use our SIM
We know it can be very frustrating when technology doesn't work the way we expect it. While we weren't able to nail down your specific problem, we would love to hear more so we can fully investigate.
UPDATE: Thank you for letting us know you used this in Cancun, MX. Again, we cannot find any customer named keng, we don't know what device you were using, we cannot find any support tickets for keng. Please help us understand who you are and the problem you encountered. It is very possible you were in an area of poor coverage. In MX we use TelCel for service (TelCel is the best network in MX). This service is available at 2G, 3G. and 4G speeds. If your device is able to use the MX bands for 4G service, then you should have received 4G speeds. But there are many factors that play into the speed of the data connection.
Again, we are sorry you had a difficult time and that the speed was not what you might be used to.
Regards,
OneSimCard Support
OneSimCard ~ A Company With Integrity & Efficiency
I got OneSimCard Universal in FEB 2023 & I'm one happy customer ! I'm an Australian who travelled to Singapore, Malaysia & California,USA using OneSimCard. I was apprehensive at first that I could use just one SIM card for three countries & more. I had no problems whatsoever throughout my 21-day trip as I read thoroughly the user-friendly operational manual available on their website. I simply opted for the Zone A Data Plan which cost $20 for 30 days with 1000 MB which was more than sufficient. I used only WhatsApp when making calls because I could use home wifi when staying with relatives & turned on Mobile Data & Data Roaming when I was outside. I had no problem using Uber & other ride share apps which required only mobile data which I had plenty using Zone A Data Plan. I found using WhatsApp with Data was a cheaper option than making regular voice calls. I made sure I switched off both Mobile Data & Data Roaming when not in use to prevent data wastage. As such, I still had about 500 MB data leftover from the 1000 MB ! Perhaps those who complain about this mobile service should look into this. Although I'm not very tech savvy, I must thank Gino from OneSimCard Support team for patiently answering all my questions so I can make an informed decision on which SIM card to choose for my requirements. My many questions were swiftly replied via email & also by phone in record time. His replies were clear, targeted & precise which ultimately resulted in clarifying my doubts. I made my purchase confident that I can rely on efficient customer care should I ever need it. So yes, I would highly recommend OneSimCard for seamless mobile phone coverage when travelling.

Ripp-off - not supported by German Network Providers
German network providers do NOT support this Simcard. On the website they claim that they cover Garmany but I am from Germany and it doesn't work - their support confirmed that their simcards are not coverd by German network providers. This might affect other European countries as well since e.g. the simcard is not working for telecom.
Now I want my money back bcs. they make false claims on their website and it is not working for me in Germany but the support is not responding to my mails.
Additional they are very expensive compared to other providers. Look for other providers!!
Especially when you want to travel in Europe or if you have family/friends in Europe.

Hello,
We tried to explain this in detail. Your German telecom provider wouldn't allow calls to our SIMs with European numbers. This means it's an error from that German telecom company, not our SIM cards. Your SIM was able to receive calls from any other number, that would indicate this is an issue with the service provider that is dialing out not receiving the call.
There are two options on how to fix this, one was to get a PEN number on your OneSimCard that your German number would be able to dial, or two you could call your German phone provider and have them take off what is blocking the calls. Please feel free to reach out to our support for more help with this or for us looking into a refund.
Thank you.

SCAM! STAY AWAY FROM THEM!
They are nothing but a scam.
I bought an e-sim from them as I am going to be travelling internationally.
When I installed the SIM in my device it would not get any service. I called a customer service who had me do a lot of things, including erasing the SIM and then reinstalling, but none of them worked. Later he tells me he will escalate the situation and then I receive and email saying I have to activate my data pack to get service. Since I had time, I decided to only activate the data right before my travel and after activating I still did not get any service. When I contacted the customer service again, they had me do a bunch of stuff again and finally at the end they say you cannot erase and reinstall an e-sim and so I cannot use that SIM anymore. I would have to buy another one just to use it.
Keep in mind that when I reached out to them, I told them what are the things I tried, including reinstalling the sim. They however only decided to let me know that my SIM would not work after wasting my whole day going back and forth, telling me to trying different things.
Therefore, it is quite clear that they do not know what they are doing and so making up an excuse just to get even more money out of me.

I really was looking forward to using OneSim eSIM
I really was looking forward to using this eSim product as it would have solved a few problems for me, however this is the most expensive and confusing option for any travel data needs. The data plans are at least FOUR times the cost of a travel SIM purchased locally. The plans themselves are very opaque and need to be simplified dramatically to service the needs of all customers. I submitted a support ticket (Ticket 266679 for the OneSIM people monitoring this site) which was initially promptly responded to, but I still haven't received a response to a clarification question. This product has so much potential, but the delivery of the product is confusing (probably deliberately so), very expensive and certainly not worth the money. Don't get me started on the confusing website and the atrocious android app to manage your account with. The app freezes on both of my Google Pixel 7's and is unusable.

Nit as good as it seems in writing …
Well after following the complicated dialing instructions (while visiting Barbados),no calls went through.So I have wasted about $100.
Promise by email to address the matter did not materialize.
I would advise people to wait until they reach their intended destination (in this case Barbados ) and you'll get a far superior,easy to apply,product for half the price. Now 12 days and still waiting to get it up and running

They just want me to by another sim card and my current is not even 2 onths old.
I was ask to purchase an upgrade sim on 9/10/22 and then they put out an OAT update soon later. I tried many time by following their customer support's suggestion but could not get the update. Which means my card will be useless after 12/31/2022. They wanted me to buy another new card but my current card is not even 2 months old yet.

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.

Very poor
Very poor. Onesimcard is supposed to be the "travellers' SIM", but when I filled in their purchase form I had 3 problems:
1. they didn't accept a non-US mobile phone number as my home mobile. So I had to invent a fake phone number just to progress my purchase.
2. they refused to accept a non-US post code - do travellers only come from the US?
3. when I contacted the "Help" chat, the guy got annoyed, and wrote "why is your delivery address different from your home address?" What?? Does the "travellers" SIM company not understand the nature of "travelling"? (ie: being somewhere other than home).
Naturally did not buy the SIM, and judging from these other reviews, I had a lucky escape! But I did waste an hour of my precious time because of their incompetence, so they get the review.

A complete waste of time for IOT applications.
1. You cannot find a rate. It is very well hidden. They do not show up until you activate a card.
2. There is a lot of stuff to fill out before activation. Some of it makes no sense.
3. Once activated, rates show up. Rate is $0.25/MB This is RIDICULOUSLY HIGH. I can certainly see why they hide it. They are competing with some that are near $0.02/MB

Thank you for the review and feedback Charles.
We tried to reach out to you when you registered the Starter Kit from your purchase on Amazon, but never heard back. Unlike other providers, we customize our plans for each use case depending on the individual needs of the individual IoT solution because of the uniqueness of these solutions. Companies who offer a "one-size" fits all approach tend to not fit any IoT solution. Our pooled data plans can get below $0.01 per MB depending on the use case. What you are seeing is our "rack rate" meant only for initial testing, and not meant for production.
I am sorry you decided to not answer our several attempts to reach you and create a true partnership with your organization and ours. If you decide you want to have this conversation we are more than happy to discuss your requirements and design a solution for you.
