I am currently using an iphone 16 as a work phone and on our last cruise (MSC) the phone was not able to connect to the ship’s wifi.  I was told by the cruise line that it was because of Jamf protect running on my phone and that was blocking the phone from recognizing the wifi signal since it was a new wifi network.  I have had this same issue in the past while attempting to connect to a wifi network in a hotel or restaurant that was not a typical network for my phone.  I am trying to figure out if this is indeed correct or if there are settings on my phone that should be toggled on or off to allow it to access the internet through a wifi network that is not familiar to my device.  Any help would be appreciated.

Are you leveraging the ZTNA portion of jamftrust? I wonder if the cruise ship is blocking any sort of VPN protocols or something.

I’d purchase a Unifi Travel Router and use it since you’d control the network at that point and only use the cruise ship’s wifi to connect the router to….even though it’s probably too late at this point.

Since you mentioned hotels and restaurants this means they’re most likely using captive portals. This blog post on Jamf’s website mentions they’ve had issues with them in the past, but introduced a feature that allows them to function. I assume you’re an enduser so I’d bring this up with your IT department.

Have you contacted your IT department? To me this sounds like a captive portal issue which would have nothing to do with Jamf Protect itself.
