SoundCloud is one of the biggest music streaming platforms in the world, and mobi.soundcloud.com is simply the mobile-optimized version of the same service. When you visit this subdomain, you're still dealing with the same company: the legal entity behind SoundCloud is clearly disclosed, and the site has proper privacy and terms pages.
The technical side matches what you'd expect from a major entertainment site. Security is tight with modern encryption and browser protections. The site loads quickly from Amazon's edge network, and there are no blacklist flags or malware warnings. The biggest curiosity is that the site blocks search engine crawlers via robots.txt, which is unusual for a business but doesn't affect your experience as a user.
As for whether mobi.soundcloud.com is a scam or fake, there's no evidence of that. The domain history goes back years, and the brand itself is trusted by millions. If you're looking for mobi.soundcloud.com reviews from a safety perspective, this one says it's fine. Just use the same caution you'd use anywhere online: don't click suspicious links within player widgets, and stick to official app downloads.
