Commercial telegram&#x27;s thing of the past, but if you want to experiment with it, there&#x27;s the National Traffic System if you are in the US, other country may have similar system in place, ran by radio amateurs. You can pretty much send non-commercial message to anyone (as long as third-party message is legal in the country for domestic message, and originating&#x2F;destination country have third-party agreements.)<p>Although, it can be bit challenging to get hold of someone who can actually place a message to the system. (If you have a license, you can actually originate message yourself through your local NTS net.)<p>[0]: <a href="http:&#x2F;&#x2F;www.arrl.org&#x2F;nts" rel="nofollow">http:&#x2F;&#x2F;www.arrl.org&#x2F;nts</a>
