Read the new but couldn't find any indication of how they'll enforce this. Is there anything known? Since Telegram has an API, banning the app alone wouldn't do any good. Banning technology is one of the hardest things a government can attempt if they simultaneously want their industry to flourish and at the same time stay competitive.
They will block IPs belonging to telegram. So links will not work, maybe some other problems. Anyway turnong on VPN on your phone will fix it eventually. So no one cares about this ban.
