It’s my goddamn motherfucking mobile data and MY PHONE. I should be able to use it however I want. My wifi went down because the greedy, cunt-faced shitbags at Comcast stole taxpayer subsidies to enrich themselves instead of actually providing the service we’re paying for. I tried to switch to a mobile hotspot and my phone refuses to open one. Everyone responsible for this shit should be fed to alligators locked away in a fucking gulag. We have no rights and live in a corporate plutocracy.
They can detect you’re using a hotspot, if you don’t configure the devices connecting to hide it. But without it being one of their phones, they wouldn’t have any software barrier to prevent it. They could, however, merely apply a charge to your account.
