Service going downhill since 2023.
It was great a few years back, bought like +100 phones, but OnlineSIM in 2024 is :
-90% of phones are not working,
-support telling you to change your ip before buying new phones (???) which doesn't work lmao
-sometimes don't get any refund when the number is not working
-2/3 times after the first SMS any SMS received during the period won't appear
Really bad service, might work if you need 2-3 temp phones max and if you're lucky, but that's it.

None of the numbers work.
Sure, you get a "refund" if one number doesn't receive the sms, but the fact is that none of them ever will. What you won't receive a refund for, is the money you originally added to the service.
Please alert your credit card/eMoney service, they might have more leverage to get these guys the flak they deserve.
In other words: a tiny front-end to a random number generator that won't ever receive any message. Watch out.

It looked promising but in reality all numbers are already blacklisted. One that wasn't blacklisted didn't manage to receive a verification message. Waste of time and money. Also, company based in Russia.

Put $5 in and couldnt get a refund. SMS phone numbers don’t work at all and you’ll never find one working after hours of going through phone numbers. Don’t trust these fake reviews. This service f***ing sucks.

Signed up. Deposited $10 USD. Tried a number. It worked. Tried another, didn't work. Now the only numbers I can get will not verify. Seems a bit odd that they give you one good number after making a deposit and now none of them can receive an SMS. Also, the numbers I keep getting are from a specific range, like 0987 xxx xxx. So it doesn't matter how many times I try and get a number they all come from that range which is blocked/not working. Total waste of money.

A scam site, do not deal with it. If you have any problem with them, no one will help you. You will remain as a person without a mind. Well, I have a problem because I charged my account with him. After charging, the balance did not increase for me. I said I will wait 30 minutes. Well, after waiting, the balance did not increase. I message them, no one answers. I search. On the way to open a file to solve the problem, there is no one. I contacted them on Telegram, and they tell me that I should wait. I really want to tell you that our site is a scam without anything, and the guardians or guardians are young children who control it. Therefore, I do not advise you to use this site at all.
When I sent the person on Telegram and he answered me, I told him to solve the problem for me. He told me that he could not solve any problem, and the bottom line is that they are a fraudulent company that should not be dealt with at all. Their numbers are rubbish. Their treatment is rubbish. Everything is rubbish.
