Bypass WiFi device restrictions

I’m on a ship to Germany for 2 days, the cost for access to starlink was $48 (half of my ticket!)

And that’s just for one device

On iOS you can’t hotspot from an internet connection, is it possible to share it from an android phone?

This is the way. :)
Also, I think it's worth noting that Windows computers allow you to hotspot a WiFi or Ethernet connection

Most Android devices support hotspotting WiFi or Ethernet but I think the only major exception is Samsung for some reason? Some devices do have it under a different way as well, for example my old Honor phone on EMUI 9 called hotspotting WiFi as "WiFi Bridge".
 
You are fortunate that the network you are connected to is not monitoring the TTL of the packets being sent in. Unless lineage OS is doing something special it would be easy enough for them to reject packets from the hotspot devices which would have a different TTL but continue to allow packets from the original device.

I can't remember any problems with my Samsungs - unless I am misunderstanding what you are trying to do.

You can hotspot on iOS?

I would be interested to see if hotspoting off android, windows or iOS works. Fair enough If you can't be bothered testing.

Without looking into this in great detail, the terminology depends a little on the internet connection which is available.

If a mobile phone has internet connection via a mobile LTE or similar connection and want to share this with other devices, I believe Apple historically used the terminology of "tethering" and more recently "personal hotspot", whereas Android referred to this as a "hotspot" going back a long time.

As we are talking about a ship and satellite communication, I don't have sufficient experience to know if the service would be provided via LTE (or similar) or WiFi.

As the LTE case is already handled above, we can consider that a mobile device gets its internet connection by WiFi and wants to share this with further clients. My understanding is whether or not this is possible depends on the availability of further WiFi radios within the device to be able to act both as a WiFi client and additionally as a WiFi access point (AP) to further WiFi clients.

Assuming sufficient WiFi radios (e.g. in a capable WiFi router), this WiFi AP could also be called a "hotspot" as this is a rather generic term.
 
My understanding is that the OP wants to connect to the Wi-Fi service on their phone and then also share this out using the Wi-Fi radio on their phone, which on a hardware level would require two radios and the software to support this functionality.

The cost of accessing Wi-Fi on a ship is going to be set partly to work as a natural way to suppress demand for quite limited satellite bandwidth.

It can be done with just one radio, but your access point would be restricted to using the same channel (and presumably channel width.etc) as the network you were acting as the client to.

OpenWRT and RouterOS can both do this via virtual AP/Subinterfaces as can probably various other devices.

It will also reduce the performance as the single radio is effectively having to receive a packet then re-transmit it, pretty much the same as wireless repeating/wireless meshing works for devices that do not have a dedicated radio for that purpose.

We’re getting around 120mbps down and 40-60 at a bare minimum, I don’t imagine that bandwidth is that limited here

The option isn’t available on iOS but is on android

Do you have a VPN? Does using port 53 work?

I would be interested to know of a model that can do this with one WiFi radio that isn't a repeater.

I've used DD-WRT, OpenWRT, and RutOS/OpenWRT as simultaneous WiFi client and AP but have been under the impression two radios were required for this configuration and would love to be corrected and learn the configuration with a single WiFi radio.

Probably, a URL to the single-WiFi-radio config would do. The closest I can currently find online is internet connection on 5.0 GHz radio, and clients on 2.4 GHz radio, optionally the other way around depending on distances.

Reading the reference makes me wonder if other routers provide similar functionality as "Guest WiFi" instead of calling it "Virtual AP".
"Guest WiFi" usually includes client isolation, so that local devices cannot talk to each other.

What you are looking for with Openwrt, is WWAN, Wireless WAN:

GL.iNet call this Repeater Mode, so you have your little Mango or Opal all ready configured with your Wireless network, you then go via the GL.iNet App:

And set up the Wireless WAN repeater connection to connect to the Hotel/Cruise/Train/Plane WiFi, and then finish configuration through the little USB powered device.
 
Stock OpenWrt can do it on most platforms I think, but I don't at the moment have anything to hand to test it on, from memory you set the primary wireless interface as the client (As it needs to be able to control the physical radio config, e.g channel.etc) and then you create a sub-interface/virtual for the SSID you'd want the clients to connect to..

Config wise for the virtual ap it's very similar to adding a 2nd SSID to the same parent interface.

If you wanted to do clients on 2.4ghz and connecting to a 5Ghz network then yes you would need 2 physical radios for that.

Also depending on the design you may find even if the device had 2 radios that could switch between 2.4ghz and 5ghz operating them both on the same band may cause co-channel interference. It would depend on how close the radios and their antennas ended up to each other.
