Packet over radio does exist, and it’s sloooooooooooooow and there’s tons of loss. Imagine the first modems over phone lines, then slow it down more.
Legally, in the US, it can’t be encrypted, either. A single geostationary satellite would be faster, especially if latency wasn’t an issue.






It’s also slow AF. It’s potentially faster to have someone read you text than get it by packet over radio.
