That sucks but it sounds familiar. And not even a data only sim works for pure data? Are you in Oz?
The only thing that I can think of is a mobile / pocket wifi…but then you’re carrying two devices.
If you are in Oz, I can suggest a reasonable, local, cheap and not terrible dumphone-with-tethering that could suit that use case (plus you know, be an actual phone lol). Suprisingly decent for under $170. Might even be able to forward calls from it to your FairPhone (as it runs Android 8.1)
Once my main phone (2019 Samsung) bites the dust, it might actually become my main daily driver again (with small tabet as OTG compute)









I dunno if I’d trust it with anything sensitive, but this might be something
