Orange, like many ISPs, blocks certain ports on residential plans to prevent spam and security abuse. Commonly blocked ports include: orange+communication+ftp
However, outgoing FTP connections (you connecting to an external server) on port 21 are almost always allowed. If you are trying to connect to an FTP server (e
Orange residential ISP routers (Livebox) generally allow outbound FTP connections. However, inbound FTP (hosting a server from home) requires configuring the Livebox's NAT/PAT settings to open ports 20 and 21. This is a security risk and generally not recommended for residential users. However, outgoing FTP connections (you connecting to an
Orange offers cloud storage solutions (such as "Orange Cloud for PC"). While end-users interact via a web interface or sync client, the backend communication for these services utilizes encrypted protocols (HTTPS, WebDAV) rather than legacy FTP to ensure data security in transit.

Can you use FTP over your Orange mobile data plan? Yes, but with important caveats.
