"Texting" doesn't require a whole heck of a lot of bandwidth. One of the most efficient Amateur Radio digital modes, PSK31 requires only 31.25Hz for up to 50WPM (32bps), requires very little power and performs excellently under difficult propagation conditions.

I am fairly sure the VLF system has evolved beyond simple CW.
