  - not only are text messages very small amounts of data, but they have their own control channel in the wireless network — and this channel is being used by the carriers in their operations whether a text is being sent or not
  - Operating costs are relatively insensitive to volume. It doesn’t cost the carrier much more to transmit a hundred million messages than a million
  - unlimited plans

  - A text message initially travels wirelessly from a handset to the closest base-station tower and is then transferred through wired links to the digital pipes of the telephone network, and then, near its destination, converted back into a wireless signal to traverse the final leg, from tower to handset. In the wired portion of its journey, a file of such infinitesimal size is inconsequential.
  - Perhaps the costs for the wireless portion at either end are high — spectrum is finite, after all, and carriers pay dearly for the rights to use it. But text messages are not just tiny; they are also free riders, tucked into what’s called a control channel, space reserved for operation of the wireless network.
  - That’s why a message is so limited in length: it must not exceed the length of the message used for internal communication between tower and handset to set up a call. The channel uses space whether or not a text message is inserted.
