Except they're not taking the whole country offline. AFAIK even simple VPNs work without issue. Iran took the whole country offline, because their country barely functions, and still some people managed an external connection.

> Iran took the whole country offline, because their country barely functions

Iran took their whole country offline because they locked the country behind CGNAT - which is an ideal tech for offlining an entire nation.

They managed the external connection because they were being provided with one by outside nations trying to topple the government. They were promptly arrested and the "protests" fizzled out. Trump then bombed them anyway.
