I'm already aware of them. They are minorities, as are the Marionites. The Copts are not Roman Catholic. They are long established minorities as are Russophone Catholics who date back over two hundred hers.
The Vatican cannot operate officially within the PRC, but I appreciate the real situation is more complex.
Please also consider the GL-iNEt Puli (XE300):
- 5V 2A USB C connector and a 5000mAh battery
- SIM and [not tested by myself] eSIM support.
- Tailscale and Nebula available as a plug-in.
- Main network and guest network can be set.
- OpenWRT if you want the GL-iNET firmware.
I am running a Netgear Nighthawk when I am on the road. But the Mubi7 looks interesting - I would not want to go back from 5G to a slower networks, sorry :)
