OneSimCard

The service itself works reasonably well, but be sure to read the fine print, and minimize the funds you deposit unless you are using the service constantly. If you don't travel abroad frequently and use up the deposits they will be confiscated and you will lose them entirely. It is very different from Skype and you should understand that if you deposit more than the minimum amounts ($25) you are at risk.

I have been a OneSim customer for over 15 years. It is cheaper to use this SIM card and a personal extra number in Canada than any of the price-fixing Canadian monopoly telecoms. I have used the card all over the world and the technology is all it says it is. Technology is a complicated thing these days and customers get annoyed if it does not work. And some parts of OneSim do not work in certain countries - SMS in UK for example on certain plans. Customer service is exemplary - real people answer your queries or e-mail you promptly if they are overly busy. Recommended highly from this customer.

I used up Europe & More card with $75 for 2GB deal and thought I can add at least 2GB by adding $100 to the balance of the account - the balance was $0 next day. After chatting with David from customer support on their web-site, it appears that they charged per mb rate which is huge ripoff instead. David wasn't very helpful, even seemed intentionally dense. Don't use this card - you can buy much more reasonable card from local European vendors and they will not be intentionally confusing. There are some consumer protection laws in Europe

First Sim card would not accept calls. Took them 2 days to fix that problem.

I was never able to send texts to the U.S. Also unable to text any pictures. And unable to text two people at once. Called tech support, and they were no help. WILL NOT USE THIS COMPANY AGAIN.

Horrible service. In their description, it states: USA Phone Number for 2 step SMS verifications and alarms from PayPal, Banks and financial institutions. However, after purchase, it can not receive txt code from etoro at all. ( etoro is just a normal financial institution). And I checked on phonevalidator website, the phone number they provide is a VOIP number! Who would pay 79 dollars for a VOIP number?! Google voice is free!

Not as described and way over priced!

OneSimCard service has been down for two days. No updates. No Live Chat. Failure to communicate. Stufrf breaks and that is understandable. What is unforgiveable and potentially dangerous to my future welll-being should I not be able to access my funds in a medical emergency, is the FAILURE of this company to communicate when they have a problem: No updats; No phone response; Time out on Live Chat; No email communication. This is unforgivable and, for this reason, this is a company to be avoided.

OneSIMCard SIMs comes with an Estonian cellular telephone number. While OneSIMCard technical support service says the number works - - it does not work universally. You cannot call it from an AT&T or Mobal cellular account, nor from a Verizon Fios or Pioneer Telephone land line account. The only way to reach it to call its assigned US number which costs extra. That obviates its usefulness overseas since you will not receive free incoming calls on the US number. Truly an unreliable product to stay away from. Ken

This company is only one of two companies where you can buy an eSIM for your Samsung Galaxy Watch! The other company (GlobalRoaming) I did business with was totally horrible, however, OneSimCard is such an awesome company with great tech support and customer service! They really care about making their customers happy and go out of their way to help you if you have problems along the way. Installing the eSIM is quite simple, just be sure to follow the Samsung guide on how to do it first and it goes much quicker! This company is also great about making sure you have a phone number that works where you live and you just ask for a PEN add on to the service, its also very quick and easy! I hope you enjoy OneSimCard as much as I have!

If you have any questions please feel free to ask me and if I can I will be glad to respond!

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 (see screenshot below). 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.

I not recomended this service. If you want credible service for traveling with wordwide SIM card, choose another service. 23 days with this support and result is $#*!. I definitely not recomended this SIM card service. Terrible support!

And also is very expensive, they have unprofessional support.
I not recomended it. Please, choose another services.

This service is terrible and the and borders on fraud. There is all kinds of fine print everywhere in their website that is impossible to fully read without enormous effort before you enroll. Numerous calls from the US to my personal extra (PEN) number did not go through. In a two week trip to Greece and Israel I had to contact tech/customer support eight times. In the iPhone there is a profile that gets installed that shows you the remaining balance on the account. It was showing a balance of $25.55 (after starting with $30) when a business call I was on was disconnected because of insufficient funds. I was told I had to activate the additional $20, which I did, only to be told it was used up already when my call was disconnected, despite paying for $50.00 in data and voice service when I enrolled. I primarily used WhatsApp and I was using the OneSimCard voice VERY little during this trip. I still cant figure out what happened to the additional $20 that disappeared. I plan on disputing the entire charge with my credit card company.

I paid 79.90USD for their 2-step verification sms number.
The number worked and I did receive the sms code sent by PayPal but then PayPal suspended the account permanently saying the number used when opening the account is fraudulent&stolen.
Do not use their service if you are looking to get a US Number to open a PayPal account and for receiving 2-step verification SMS codes.

It worked in Cuba but very, very expense, more than Cubacel network. It spent $45 in just 2 smalls calls between Havana and Santa Clara. Also it is not friendly. Not recommended.

Scammer. Don't fulfill the promise. When I asked for refund the money because they didn't fulfill the promise that's time close the live chat support by themself.

Even though I knew that buying local sim would be cheaper than buying just one international sim, I wanted to make things easier while travelling and choose onesim card.
However, their web is totally not user friendly and I think they kind of do it on purpose to deceive you and get more money.
I bought a 5g data package and left 125 dollars credit in the account, planning to use it to buy another packages in the future. (You can only recharge from 25 to 25 dollars, but the plan costs are not round numbers, which make you always leave a lot of credit inside it).

After my package was over, without informing me anything, they just start using my credit and charging me a absurd cost 20x higher for mb. I didn't know I was supposed to log in the web, and confirm that I wanted the discounted package price (isn't that obvious?!?!). When I noticed that I was navigating without a "discounted packaged activated" I realized they have charged me 120 dollars for 2 days internet usage (no videos, only what's app and web).

I tried to reach out the customer service, but they haven't provided any help at all!

I purchased an esim world and it didn't work in my country, they wouldn't refund me even though I didn't install it, thry blocked me also, not good people,

Could not make or receive phone calls. Seek another sim card company. Their tech support in Italy, yeah ok, non-working sim card, no phone, no tech support and no refund! NOT RECOMMENDED!

Avoid this card. Rip off. Better off buying a card at your destination. Billing is problematic and your money will disappear.
