888-380-9638 has been shut down by Sangoma. Calling the number now presents a disconnection message.
Not all numbers that say “Onvoy” are on Sinch. Onvoy appears to be a pool that various telecoms take numbers from. Telecoms like Text Now, GoTextMe, Text Plus, IP Horizon, Vonage, Bulk, Pinger etc… may sometimes use numbers on Onvoy. In that case, it is best to contact them directly, which is the case for 917-722-5897, which states “Onvoy” but it was actually on IP Horizon. It has been shut down. Calling it now gets a disconnection message.
The Sinch webform does work, you just have to get creative when sending evidence to them. Yes, the form doesn’t have the option by default but there is a way to do it. Think about it. Scammers read scammer.info so I cannot disclose how it’s done but trust me, there is a way. How else would you send things to people online, even with no options to do so? Think about it…
Yeah, it’s frustrating. It’s very seldom if ever that I get the actual text.
The way I get these numbers is that I have a couple of contacts on social media who send me only the numbers without the screenshot.
Additionally I search reddit too where people post “Coinbase” numbers without any screenshot, here’s an example:
Reporting to Infobip now. It’s an Onvoy number on the Peerless network.

8333977837 this another one that they are using and will use to call you back with. It’s on Amazon VOIP service. If anyone has a reliable and verifiable way to contact Amazon in regards to reporting numbers to them, please let me know.
17865078897 has been shut down by Peerless in one hour. I accidently sent the first email to an old, outdated address. This numebr appears as “Onvoy” but it was actually on the Peerless network via Infobip. For Peerless, it’s best to contact Infobip directly, their parent company at [email protected] Always have evidence when emailing carriers.
Can’t find anything else other than their own abuse reporting form
