Unfortunately their UK network is awful, slow and broken, so I had to leave them. But I really miss the roaming.
Not idea whether they actually check/apply this though.

Except that provision of basic mono-utilities such as drinking water, roads, and The Internet is probably best provided by the state. At least the cell phone tower part, leaving the internet exchange part upwards to private companies.
(This pre supposes a level of benevolence / lack of malevolence from the state, or a faith in protocols further up the stack to have end to end security. At least one of these exists.)
