Hello. We are truly sorry to hear that you experienced issues with our service and believe it to be a scam. We understand your frustration regarding the non-working numbers and the disappearance of your credit, and we want to assure you that we take these matters very seriously.
We are not a scam. Our service is designed to provide functional numbers, and we always strive to ensure that our clients are able to receive SMS to their purchased numbers. Importantly, our system only charges you when an SMS is successfully received on the rented number. If a number is used and no SMS is received, no funds are deducted.
In cases where a number is used and an SMS is successfully received, we do guarantee a refund for that number. If the purchased number ends up being used and you did not receive any SMS, you may simply cancel that number and try another.
To help us investigate your particular situation further and provide a resolution, we kindly ask that you reach out to our support team, so that we can try to understand what exactly happened. Please provide us with your account ID (if possible) and the specific numbers you used.

No where does it state when using the recieve SMS feature does it state you can only use the number for 15 mins, and after that you can never access the number again. Support are terrible, specifically the support agent 'Maks' was very unhelpful, rude, and uncooperative. Avoid this company!

Tricky tariffs for sms recieve, on main page 100sms costs 0.80$ but if you register and go to page with plans i can see 100sms costs 35$ already
Reply from OnlineSIM2024-10-11
Hello! Thank you for your feedback. We apologize for any confusion regarding our SMS pricing. Our homepage lists the price as $0.80 per SMS when purchasing a 100 SMS package. For example, if you purchase a 3 SMS package, the price per SMS is $1, but purchasing a 100 SMS package reduces the price per SMS to $0.80, which provides significant savings in the long run.
If you have any additional questions or need assistance, please feel free to contact our support team!
Thank you for your understanding.
Horrible service and company. They don't honor their refund agreement publicly stated on their website. Argue with you saying that the refund agreement only applies to specific services, despite that not being stated in the refund agreement. Not surprised by the other terrible reviews here.
Reply from OnlineSIM2024-10-11
Hello! Thank you for your review. We appreciate you bringing your experience to our attention regarding our refund policy.

Thank you for your understanding.
I topped up 13 US Dollars to receive some sms on a philippinese phone number. as soon as i topped up that amount of money i got redirected to a site "secpayment.idealniche.net" which confirmed that my payment has been succcessful. at the onlinesim.io homepage it tells me that my payment is processing. after waiting another 10 minutes i decided to contact the support via chat. they promptly replied that i must wait atleast 30 minutes for the payment to complete if not completed after 30 minutes i should contact him again and send him the payment screenshot. 30 minutes passed and i send him a message that its still not working and the screenshot attached. the support told me that my problem has been forwarded to the technical specialists, which are working only during business days from 10am-21pm moscow time.
the time i topped up the amount of money was at 23pm so i needed to wait about 12 hours..
i told him that i need the service urgent and that i want to cancel the payment.
since then 3 hours passed and no response. i think it looks like a scam!
Be aware!

Good day! Thanks for your review. We apologize for the inconvenience you experienced with your payment and the delay in receiving assistance.
Our goal is to provide timely support, and we understand how frustrating it is when things don't go as expected. Sometimes payments may take longer to process, especially outside of business hours.
If you could provide the account id and proof of payment (txid or receipt screenshot), we will prioritize your issue and work on a solution, including the possibility of a refund if that's convenient for you.
Thank you for your understanding, and we appreciate your patience.
Good for some accounts. But not all and not Google.
In the beginning I was very disappointment as google does not work. But I have tried other services and they are working fine. Yahoo is working like 75%. The good thing is, if you don't receive msms you are not charged.

Good day! Thanks for your review. We are sorry to hear about your experience with our service. We take these issues seriously and are committed to ensuring that our numbers are working for our users.
As for your verification issue, we understand how frustrating it can be. The error message you received may be due to certain restrictions from Google, as the error "this number cannot be used for verification" means a problem with the browser cache and static IP address.
Please provide your account ID, it would help us to look deeper into this issue. In addition, we recommend that you contact our support chat with a request to transfer you to a technical specialist for further advice and resolution of the issue.
Please do not use this website.
They will steal your money ,the phone numbers they provide do not work.
When I engaged in conversation with customer services the contact was absent and not responding to my questions.
He told me they would not use the credit if the phone number did not work.
I was given 4 numbers that did not work and my credit was depleting each time.
The credit is useless anyway as none of the numbers work.
As of now the customer service agent has not replied to me for about 30 mins ,when we are actually in a conversation he is busy lying to other customers.
I don't like being lied to or stolen from.

It's a scam site. I have had to raise a chargeback with my credit card company (thankfully I didn't use a debit card with them!) The website falsely says they have sms numbers you can rent for 15 minutes to get verification sms' sent to. I loaded my balance they suddenly all were out of stock apart from two other more expensive in stock countries - Kazakhstan and Russia. Gee just what I always wanted a Russan phone number. Anyway even after (supposedly) purchasing the numbers they were deemed unsuitable for verification because they were ID'd as virtual numbers. Yet this website advertises it's numbers as being suitable for verification. Thankfully my card company is getting me a refund. Don't waste you time/money.

They are using fake payment gateways to steal your card details.
One is 3ds[dot]payment-acquirer[dot]com, fooling people to belive it's MasterCard but it's a totally pishing website.
