Hi everyone,
I’m working as an IT engineer in the cruise industry and need to troubleshoot passenger complaints about Apple’s new RCS messaging feature (introduced with iOS 18). Could someone help confirm which domains and ports iPhones use when they send RCS messages? My firewall team wants specifics: domains (or subdomains) that need whitelisting and the ports involved.
Any official or community-sourced info would be super helpful—thanks in advance!
DevForum is primarily focused on APIs, whereas your question is more about the on-the-wire behaviour of the device. It’s possible that someone might chime in here, but I think you’ll have better luck asking again over in the Apple Support Community, run by Apple Support, and specifically in the Business and Education topic area.
Share and Enjoy
