That’s true, but I found parts like the bottom chassis, display assembly and keyboard on Aliexpress. They probably have the joystick modules too.
The only thing I couldn’t find were the actual rubber thumbsticks, which might become a problem in the future when they wear out. GPD promised to sell them individually a while ago, but as of yet, they haven’t done so.
Vodafone has a hotspot service here in Germany. All of their cable routers have a second wifi network everyone can use (unless you opt out).
When they introduced it, it had a big flaw: They stored the MAC address of your device in their database as authorized, but never deleted it.
Hypothetically speaking, you could pay for a month, cancel the service and then browse for over a year until they noticed you and kicked you out. 😆
But I would never do that, of course.
