Kevin Karhan :verified:Seriously, there's a reason why every other nation at the very least keeps the absolute minimum of bandwith necessary to maintain <a href="https://infosec.space/tags/2G" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#2G</a> & <a href="https://infosec.space/tags/3G" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#3G</a> service for <a href="https://infosec.space/tags/EmergencyCalling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EmergencyCalling</a>.In fact, <a href="https://infosec.space/tags/Germany" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Germany</a> learned the hard way <a href="https://en.wikipedia.org/wiki/Radio_Data_System#Program_types" rel="nofollow noopener noreferrer" target="_blank">that</a> <a href="https://infosec.space/tags/CellBroadcast" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CellBroadcast</a> and <a href="https://infosec.space/tags/PTY31" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PTY31</a> / <a href="https://infosec.space/tags/RDS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RDS</a> - based <a href="https://infosec.space/tags/alarms" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#alarms</a> and <a href="https://infosec.space/tags/sirens" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sirens</a> are not replaceable.<ul><li>It's frustrating to see that it took a <a href="https://de.wikipedia.org/wiki/Hochwasser_in_West-_und_Mitteleuropa_2021#Rheinland-Pfalz" rel="nofollow noopener noreferrer" target="_blank">triple-digit bodycount</a> to get that across...</li></ul>
