ℹ️ About SSL Certificates

SSL (Secure Sockets Layer) certificates encrypt data between your browser and docomo-rcs.lstep.jp's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real Docomo-rcs website.

Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
