I would think deliberately blocking calls would be far different from
service being unavailable for natural reasons.
The restaurant that did so would probably soon find itself shunned
by so many customers that it would have to go out of business. Even
those of us who bemoan the use of cell phones in restaurants probably
do so occasionally, and I have been in restaurants where there were

For example, any internet email client can send email to email@example.com

A huge amount of the carriers revenue most probably is coming from
texting. After all, texting is really a "no cost to the carrier" item

Why your cell phone is ripe for spam texts in 2012
By Nancy Scola
June 1, 2012
In the late 1970s, the cutting edge of communications technologies
was the autodialer, a machine capable of calling up scores of people
in one shot, with little human involvement. It was innovative, and
annoying. By the early '90s, Congress had had enough. "Computerized
calls," railed South Carolina Democrat Fritz Hollings from the Senate
floor, "are the scourge of modern civilization."
And so, Congress legislated. But the focus was on commercial calls.
Mindful of the free flow of speech and - let's be honest - interested
in self-preservation, lawmakers exempted political calls from its
Telecommunications Consumer Protection Act. But Congress decided that
some phones were too sensitive to get even autodialed political
calls: those in hospitals, those designated for emergency purposes -
and those in our pockets.
But here we are, some two decades later, and voters across the
country are getting political text messages they never asked for.

That's the nature of CDMA which is what Verizon and Sprint use. CDMA

Anyway, I did notice a number of passengers 'thumbing away', that is,

love because texting uses less bandwidth capacity than a voice call

A quick Google tells me that a GSM 'half-rate' codec requires 6.5 kbit/sec;
a 140 character message is 1120 bits of payload and the average text length
is probably much less than 140 characters so it would take several texts per
