OneSimCard False Advertising: USA Phone Number for 2-Step SMS Verification & Alarms from Financial Institutions

This service is not good at all. I read on their website that they offer a USA Phone Number for 2 step SMS verifications and alarms from PayPal, Banks and financial institutions. But when I bought it, it didn't work for receiving txt codes from etoro, which is just a normal financial institution. I even checked on phonevalidator website and found out that the phone number they gave me is a VOIP number! Who in their right mind would pay 79 dollars for a VOIP number?! Google voice is free and works better than this.

I am very disappointed with this service. It is not what they described and it is way too expensive. I would not recommend it to anyone.

OneSimCard Excellent Customer Service and Support from OneSimCard

I gotta say, OneSimCard is pretty darn good. The chat thingy on their website was super helpful, and when I needed to talk to a real person, they were there for me. Last year, I tried another sim card company and they didn't give me the same kind of service. But with OneSimCard, I feel like I'm in good hands. I haven't even left my house yet (just trying to get the card activated and be able to text), but it's nice to know that if I need help when I'm out of the country, someone's got my back.

OneSimCard OneSIMCard Review: Unreliable and Disappointing

I recently tried out OneSIMCard and I have to say, I was pretty disappointed. The SIM card comes with an Estonian phone number, which the technical support team assured me would work just fine. However, I quickly found out that this was not the case. I tried calling the number from my AT&T and Mobal accounts, as well as from my Verizon Fios and Pioneer Telephone landline accounts, but none of them were able to connect.

The only way to actually reach the Estonian number was to call its assigned US number, which ended up costing me extra. This completely defeats the purpose of having a SIM card for international travel, since you won't be able to receive free incoming calls on the US number. Overall, I found OneSIMCard to be a pretty unreliable product and I would definitely recommend staying away from it.

I was really disappointed with my experience and I hope that OneSIMCard can improve their service in the future. It's frustrating to spend money on a product that doesn't work as advertised, and I wouldn't want anyone else to have the same experience that I did.

OneSimCard Review of OneSimCard: A Promising Solution for International Calling from Honduras

Hey guys, just wanted to give you an update on my experience with OneSimCard. I was notified that my card arrived at my freight forwarder in Miami and is to be shipped to me in Honduras tomorrow. So I can't honestly comment on my use of the card because it is not yet in my possession. But I have to say, the customer service has been pretty good so far in getting my questions answered.

As someone who has been living in Honduras for the past 10 years, I can tell you that the phone service here is lacking. And don't even get me started on the calls to/from the U.S. - they always give me heartburn. So I'm really hoping that this card will be the answer to my problems.

I've heard good things about OneSimCard from other expats living in Honduras, so I'm feeling pretty optimistic. I'll definitely update this review once I've had a chance to use the card and see how it performs. But for now, I'm just grateful for the helpful customer service and the hope that this card will make my life a little easier.

OneSimCard Disappointing Experience with OneSimCard: Confusing Website and High Prices

that will help you if you have any issues with the local vendors, but with OneSimCard, you are on your own. The website is also very confusing and hard to navigate. It took me a while to find the information I needed, and even then, it was not clear. The prices are also very high compared to other options. I would not recommend OneSimCard to anyone.

OneSimCard OneSimCard Review: Good Option for International Travel, but Process Could Be Smoother

The process of getting a OneSimCard was a bit confusing for me. I had a lot of questions, but unfortunately, email support was slow to respond. I needed to order the sim card quickly so that I could have it before I left. It would have been great if there was a number I could call to speak with someone directly.

Thankfully, I was able to speak with support eventually, and they helped me set up my phone. However, when I arrived overseas, I received emails saying that my extra discount package couldn't be loaded. I texted support to ask about it, and they assured me that everything was loaded. But, I continued to receive more emails saying the opposite. It's all a bit confusing, but I'll have to figure it out later.

Overall, I think OneSimCard is a good option for international travel, but the process could be smoother. It would be great if they had a more responsive support team and a phone number to call for immediate assistance. Despite the confusion, I'm still glad I have the OneSimCard for my travels.

OneSimCard False Claims and Poor Service: My Experience with OneSimCard

This OneSimCard thing is a real pain in the neck. I'm from Germany and I thought I'd give it a try since their website says they cover Germany. But let me tell you, it's a bunch of baloney. I tried to use it and it didn't work at all. I even contacted their support and they told me that their simcards aren't covered by German network providers. What a load of crap! I bet this affects other European countries too, like Telecom.

I'm so mad right now that I want my money back. They make all these false claims on their website and then it doesn't even work. And to top it off, their support isn't even responding to my emails. What a bunch of jerks!

And don't even get me started on how expensive they are. There are way better providers out there that won't rip you off like OneSimCard does. Especially if you're traveling in Europe or have family/friends there. Save yourself the trouble and look for another provider.

OneSimCard OneSimCard Review: Scam-like Service with Hidden Fees and Poor Customer Support

This service ain't that great and it's almost like they're trying to scam you. There's all sorts of tiny writing all over their website that's impossible to read without a lot of effort before you sign up. I tried to make a bunch of calls from the US to my extra (PEN) number but none of them went through. When I went on a two week trip to Greece and Israel, I had to call tech/customer support eight times. On my iPhone, there's a profile that gets installed that shows how much money is left on the account. It said I had $25.55 left (after starting with $30) when I was on a business call that got disconnected because I didn't have enough money. They told me I had to activate an extra $20, which I did, but then they said it was already used up when my call got disconnected, even though I paid for $50.00 in data and voice service when I signed up. I mostly used WhatsApp and barely used the OneSimCard voice during my trip. I still don't know where that extra $20 went. I'm gonna have to dispute the whole charge with my credit card company.

OneSimCard Unpleasant Experience with OneSimCard: Confusing Website, Non-Transparent Pricing, and Poor Customer Service

So, I recently had an experience with OneSimCard and I must say, it was not a pleasant one. I decided to go with OneSimCard because I thought it would be easier to have just one international sim card instead of buying a local sim card every time I travel. However, I was in for a rude awakening.

Firstly, their website is not user-friendly at all. It took me a while to figure out how to navigate it. I think they do it on purpose to confuse you and make you spend more money. I purchased a 5g data package and left $125 credit in my account, planning to use it to buy more packages in the future. However, I soon realized that you can only recharge in increments of $25, which means you always end up with a lot of credit left over.

When my package was over, they started using my credit without informing me and charged me an absurd amount for each MB. I didn't know I was supposed to log in to the website and confirm that I wanted the discounted package price. When I finally realized that I was navigating without a "discounted package activated," I was shocked to see that they had charged me $120 for just two days of internet usage (no videos, only WhatsApp and web browsing).

I tried to reach out to their customer service, but they were of no help at all. It was frustrating to say the least. I feel like they just want to take your money and don't care about providing good customer service.

In conclusion, I would not recommend OneSimCard to anyone. Their website is confusing, their pricing is not transparent, and their customer service is non-existent. Save yourself the trouble and go with a local sim card instead.

OneSimCard Mixed Experience with OneSimCard's Customer Service and Ordering Process

I recently tried to get some answers about the differences between two of OneSimCard's sim card products. I spend a lot of time in Mexico and Europe, so I needed to know which one would be best for me. At first, I got some helpful responses, but then the communication stopped. I was worried that this might be a bad sign.

However, I decided to give OneSimCard another chance and reached out to their customer service again. This time, I got immediate and helpful responses right away. I was relieved to see that they were still willing to help me.

I tried to place an order for two sim cards using my Firefox browser, but the order stalled and I couldn't change the shipping address zip code. When I contacted customer service, they told me to switch to Chrome. I did as they suggested, but then I noticed that the first page of the order form was causing the problem. The shipping zip code was locking up when I entered it on the first page, and customer service didn't seem to know this.

Eventually, I was able to fill out all the information and hit "process order." However, the screen remained locked up at "processing," and I didn't get any response from customer service. I waited for half an hour, but still no reply. I decided to sign off and restart my computer.

When I signed back on with Firefox, I was finally able to place my order. However, I'm still worried that I might get double charged, so I'll be keeping an eye on my credit card.

I've been a long-term customer with Wireless Traveler, but I've had enough of their glitches and unresponsive customer service. I've heard good things about OneSimCard, and I'm looking forward to trying it out. However, I'm concerned about the lack of professionalism in their customer service. As a professional writer, I have many friends who rely on my advice about connectivity as digital nomads. Right now, I can't recommend OneSimCard to them, but we'll see how things go in the future.

OneSimCard Stay Connected Abroad with OneSimCard: A Review

I finally got my OneSimCard and it worked great during my trip to Europe. I was able to make calls and send texts without any issues. The only problem I had was trying to figure out how to activate the data plan, but I eventually got it working. The customer service reps were helpful when I called them for assistance. Overall, I would recommend OneSimCard to anyone traveling abroad. It's a great way to stay connected without having to pay outrageous roaming fees.

OneSimCard Disappointed with OneSimCard's Lack of Chat Support and Checkout Process

I recently tried out OneSimCard and unfortunately, I was disappointed with their lack of chat support. I had some questions about their service, but I couldn't find anyone to help me out. It's a shame because I was really excited to use their service for my two different phones. However, I ran into another issue when I tried to purchase the SIM cards. They only allowed me to enter one phone number, even though I needed two. I understand that they only need the phone number for information and support purposes, but if that's the case, they shouldn't require it at checkout. It would be much more convenient if I could register the second phone number at any time. This whole process slowed down my purchase and caused some confusion. Despite these issues, I'm still looking forward to receiving the SIM cards and giving OneSimCard a try.

OneSimCard Fraudulent US Number Service: A Total Waste of Money and Time for PayPal Verification

I paid 79.90 bucks 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. Don't 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's a total waste of money and time. I was so disappointed with their service. I thought it would be a great way to get a US number for my PayPal account, but it turned out to be a complete disaster. I don't recommend this service to anyone. It's just not worth it.

OneSimCard Review of OneSimCard's Interface and User Experience: Outdated and Frustrating

I recently used OneSimCard to place an order, and I have to say, the interface left a lot to be desired. It seemed outdated and not very mobile-friendly, which made it difficult to navigate. One of the biggest issues I had was that I couldn't put the name of the person who was receiving the order I placed. This was frustrating because I wanted to make sure that the package was delivered to the right person.

Another issue I had was with the credit card number fields. They didn't allow for easy input from a phone, which meant that I had to tap each set of four digits individually. This was time-consuming and frustrating, especially since the keyboard kept reading the field as a text field instead of a number field.

Finally, the review order before payment feature was limited. It didn't show all the information I had entered, which made it difficult to double-check everything before submitting my payment. Overall, I think OneSimCard has some work to do when it comes to their interface and user experience.

OneSimCard Mixed Experience with OneSimCard: On-Time Delivery but Data Access Issues & Phone Set-Up Problems

I got my OneSimCard package right on time, but I gotta say, I had some trouble getting access to my data. I had to call customer service for some extra help. I should mention that I bought a phone with some extra sim cards. The sim was already in there, but the phone wasn't set up right, which was kind of a bummer. I'm still trying things out, so hopefully next time I'll have a better experience.

OneSimCard Decent but Details Matter: OneSimCard Review

I gotta say, OneSimCard is pretty decent. It does what it says on the tin, but you gotta be careful with the details. Make sure you read all the little words and don't put too much money in unless you're always on the go. If you don't use it enough, they'll take your money and run. It's not like Skype, so don't get confused. Just keep it simple and stick to the minimum deposit of $25. Don't take no risks, ya know?

OneSimCard Decent Experience with OneSimCard, but Lack of Clarity on Charges and Phone Compatibility

I gotta say, my experience with OneSimCard was pretty decent overall. But, I gotta admit, the charges could have been explained a bit better. It would have been nice to see an example of how much it costs to make calls and send texts to folks back home. Ya know, just so I can get a better idea of what I'm getting into.

Also, I noticed that they didn't mention anything about phones from Verizon not working on their network. I mean, I get it, not everyone knows that Verizon phones don't use GSM. But, it would have been nice to have a heads up before I left the US. Now, I'm just crossing my fingers and hoping that the sim card works when I get to Canada.

But, hey, I'm still gonna give it a shot. I'll be testing it out while I wait for my connecting flight. Fingers crossed that everything works out!

OneSimCard Stay Connected Abroad with OneSimCard: Reliable and Affordable Service

I recently tried out OneSimCard and I must say, I was pleasantly surprised. My family was finally able to get in touch with me without any issues. The automated voice was no longer a problem and I was able to receive calls without any delay. The service was not only reliable but also affordable. I didn't have to worry about spending extra money on calling my loved ones.

One thing that I did notice was that the setup process was a bit confusing. It took me a while to figure out how to activate the sim card and get it working. However, once I got past that hurdle, everything was smooth sailing.

Overall, I would definitely recommend OneSimCard to anyone who needs a reliable and affordable way to stay connected with their loved ones while traveling abroad. The minor setup issue was worth it for the peace of mind that comes with knowing that you can stay connected no matter where you are.

OneSimCard Review of OneSimCard: Good Experience with a Few Hiccups

I recently had an experience with OneSimCard and I must say, it was a bit confusing when it came to getting a replacement SIM for my new iPhone. I had previously used a Nokia phone and wasn't sure how to go about getting a new SIM without having to chat with customer service. However, once I got that sorted out, everything else went smoothly.

One thing to note is that you can only use your phone balance to pay for calls. Any other charges, such as data or text messages, must be paid for separately. This can be a bit of a hassle, but it's not uncommon with other phone services.

When I received my new SIM, I had some trouble getting it to work. I ended up spending an hour on a chat with customer service to get it up and running. The chat person was extremely helpful, but it shouldn't take that long to get a SIM card working.

Overall, my experience with OneSimCard was good. The only issue I had was with getting a replacement SIM for my new phone, but once that was sorted out, everything else went smoothly. If you're looking for an international phone service, I would recommend giving OneSimCard a try.

I finally got my OneSimCard and I'm pretty satisfied with it. The website was a bit confusing at first, but I eventually figured it out. The customer service representative was helpful, but it took a while to get everything sorted out. I had some trouble activating the card, but that was mostly my fault for not reading the instructions carefully. Once I got it working, though, it was smooth sailing. The call quality is good and the rates are reasonable. I've used it in several countries now and haven't had any major issues. Overall, I'd recommend OneSimCard to anyone looking for an affordable and reliable international SIM card.
