Hello. Thank you for your feedback. We’re sorry to hear that you had a frustrating experience.
However, we’d like to clarify a few important things.
At the moment, your message doesn’t specify which type of access was blocked — whether it was access to your onlinesim.io account or to a third-party service (such as WhatsApp, Telegram, etc.) after using one of our temporary numbers.
If your onlinesim.io account access was restricted, it may have been due to:
– a temporary technical issue,
– security flags during payment,
– or an incomplete transaction.
In any of these cases, please reach out — we’re happy to investigate and assist.
If access was denied by a third-party service (like Telegram or WhatsApp), please note that these platforms sometimes restrict accounts for reasons beyond our control. We do not influence their internal moderation policies.
That said, your funds remain secure, and we are always ready to help resolve the issue.
You can:
– Contact us again via the chat button at the bottom-right of our website and request to speak with a technical specialist,
– Or reach our Quality Control Team on Telegram: @zabotaonlinesim
We are committed to addressing every concern fairly and thoroughly. Please provide your order date or account details so we can look into this further.
Thank you again for helping us improve.
Best regards,
The Onlinesim Team
I’ve tried multiple numbers from different countries on onlinesim.io, and none of them worked. SMS messages never arrive, and in many cases, the numbers aren’t even accepted by the platforms. Customer support is completely useless – they always give the same generic responses without offering real help. It feels like a scam – they just take your money and deliver nothing in return. Avoid this service at all costs.

Hello! We sincerely regret that you encountered difficulties while using our service. We want to assure you that we are not involved in any fraud and always strive for transparency in our operations.
Important points:
1) Funds are only deducted after successful receipt of an SMS. If the message did not arrive, your balance will not change – charges are applied only for numbers that successfully received SMS.

3) To resolve your issue, please contact support chat and ask to be transferred to a technical specialist. They will review your case in detail and help find a solution.

Give us a chance to fix the situation — write in the chat, and we will do everything possible to help.

When you check the site you will see Hong Kong and China listed along the Countries whose numbers are provided.
In my case, My Quest was simple: get a QQ email registered.
To My surprise after top up of the account with the minimum of $10 - for which you get charged $12, I tried and quickly found no China or HK numbers are available for SMS reception.
In the end trying to save something out of a bad Deal I tried a Chile Number for whatsapp registration which is something I have been looking for for a while, and WhatsApp couldnt even accept sending a code to the provided Number. So there.

Hello. Thank you for your feedback and for sharing your experience. We sincerely regret that you encountered difficulties while using our service and understand your frustration.
We do collaborate with operators from various countries, including China and Hong Kong; however, sometimes the number of available numbers in real-time may not match what is displayed. This is a technical challenge we are actively working to resolve, and there is no malicious intent behind it. If the numbers you need are temporarily unavailable, please try checking again later or contact support — we will do our best to help you find an alternative.
Some payment systems, especially international ones, may charge an additional fee during processing. This information is shown on the checkout page before confirming your payment. Unfortunately, we do not control these fees, but we always strive to make conditions as transparent as possible for our users.
Regrettably, services like WhatsApp often block virtual numbers, especially when requests are frequent. This is their internal policy, and as intermediaries, we cannot influence these restrictions. To increase your chances of successful registration, we recommend trying numbers from other countries (such as Indonesia or Mexico), changing your IP address via VPN, clearing your browser cache, or using a different device. It is important to note that funds are only deducted after successful receipt of the SMS, and in case of an issue, we guarantee a refund.
We openly acknowledge that there are areas for improvement in our work, and we thank you for your feedback — it helps us become better. If you are willing to give us another chance, our support team will be happy to help find working solutions for your tasks, whether it’s registering for QQ, WhatsApp, or other services.
If you have any questions or need assistance with a refund, please contact our 24/7 support — we will do our best to resolve your issue as quickly as possible.
Once again, thank you for your patience and understanding. We value every customer and will do everything possible to make your next experience with our service more positive.
Best regards, Onlinesim Team
Continuous errors with numbers that are not generated uniquely, but are used by multiple users. You dial a number that is used by multiple users. Furthermore, those rare numbers that are not used by other users unfortunately for services like WhatsApp never arrive even by changing VPN and all the other pre-set "advice" from operators who are unable to really help you with the problem
OnlineSIM 回复2025-05-19
Hello! Thank you for your feedback. We are very sorry that you encountered difficulties. Please allow us to clarify the situation:
Number Uniqueness
Our numbers are issued exclusively to one user at a time and cannot be reused by other clients after the rental period ends (15-20 minutes for “SMS Reception” or after the rental expires). However, mobile operators sometimes reissue inactive numbers after 2-3 months, which can lead to conflicts on third-party services (such as WhatsApp).
Problems Receiving SMS
— If the SMS does not arrive, funds are not deducted (payment is only processed after the first SMS).
— We recommend:
• Closing the current number (click the red cross) and ordering a new one.
• Changing your IP/VPN and your browser/device (this increases the chances, as services like WhatsApp block mass requests).
Blocked or Occupied Numbers
We guarantee a refund in such cases. Please contact support. The average response time from an operator is 3 minutes. The average time to process a refund to your account balance is 1-4 hours.
Technical Limitations
We do not control the policies of services (WhatsApp and others) that may block virtual numbers. This is a common issue with all SMS activation services.
Important: We are constantly improving the system to minimize such situations. We are ready to assist you via support chat — we will review your case individually.
Best regards, Onlinesim Team
I purchased a verification service, and it did not work. So I reached out to support for either a refund or assistance and they ignored my attempts for assistance simply not responding to my messages. Bad business.

After reading a single person's review of saying "out on x numbers, some worked", it was good enough for me so I tried.
I needed a Turkish number for a gmail account, I selected one that lasted for 15 mins, verified with no problem and continued on my way.
The next day I tried using again a Turkish number but it says they are out of Turkish numbers, and asked me if I wanted something else close to that area, which I declined (So they probably fixed the issue with being given used number).
I have a very unexpected and positive experience, even though it looked like a scam, it worked for me. Have fun you guys

The numbers generated are very unreliable. I tried 50+ Argentina numbers for Netflix and even sent SMS from my private phone. None was received. As a test I generated a German number that didn't even look close to what mobile numbers should look like in this country. But the 2nd german number surprisingly looked right and even worked! So, the service is not 100% fake. And they don't charge the money for a number, if no message was received, to be fair. Still - no success at all with the Argentina numbers.
OnlineSIM 回复2025-03-17
Hello. It is nice that, despite the negative review, you nevertheless noticed that the service does not charge money for numbers that do not receive SMS and the fact that our site is not so hopeless and you were able to use it by accepting an SMS to a German number from Netflix.
However, as a representative of the company, I want to point out the fact that the problem is not only in the numbers. I checked, indeed, Argentine numbers are problematic and are not suitable for netlfix - we will deal with this problem and will try to do everything possible to solve it, however, I believe that your estimate of 98% of non-working numbers is greatly exaggerated. I checked and found the following numbers for netflix for the last two weeks: Thailand - 100%, Laos - 100%, Australia - 100%, South Africa - 100%, Czech Republic - 100%, Netherlands - 100%, Hong Kong - 81.81%, Japan - 76.19%, Philippines - 69.66%, Haiti - 66.66%, Cambodia - 57.14285714%, Indonesia - 50%, Brazil - 50%, United Kingdom - 50%, Peru - 42.85%, USA - 33.33%
According to Argentina numbers, the success rate is only 27.27% (15 received and 40 rejected SMS)
If you have an idea on how to deal with this issue, please write to support, be sure to tell the operator that you left a review. I will assign the case to the responsible operator, who will try to solve your problem.
I would be very grateful if you could provide me with your account ID or email on onlinesim in your reply.

Hello. Thank you for your request for a German SIM number. We understand that you are very eager to get one. We offer two ways to obtain a German number:
1. Free: You can try to obtain a free German number here: https://onlinesim.io/#free
Advantages: You can use the number for free without registering on onlinesim.io.
Disadvantages:
-A German number may not be available.
-The number may already be in use on the resource you need.
-High client demand may temporarily block SMS delivery from the sender. You might encounter an error indicating the number is used many times or blocked due to continuous requests within a short period.
-Numbers are added randomly once a week; a German number may be added, but there’s no guarantee.
2. Paid: For a guaranteed German number, you can purchase one through our website.
Advantages:
-The number is used exclusively by you.
-You won’t encounter the issues associated with free numbers. -Numbers are consistently added within 4-7 days.
Disadvantages: Registration and account funding are required.
While we appreciate your enthusiasm, we don’t provide individual German phone numbers through our review response channels. To get your German number, we recommend you use one of these two methods. If you have any questions or need further assistance with either method, please don’t hesitate to contact our support team. You can reach us through:
