Does anyone pay separately for text messaging these days?
I remember being concerned about message counts used to be a thing, because the carriers had plans with various amounts of text messages included, and they made a big deal out of how many messages each plan had. Then Apple released iMessage, wherein the Messages app could short-circuit text messages by sending it as data, via Apple's servers, instead of as a text message, through the carrier's servers, and I remembered thinking, "this is gonna p*ss off the carriers big time, because Apple is draining all the profit out of something they've been leaning heavily on the past few years (as messaging eclipsed talking)", and everyone could cut way back on their text messaging plans.
And sure enough, the next round of plans arrived from Verizon (the carrier I'm familiar with), and they'd put a positive spin on it (while grabbing as much money as possible themselves) by saying, "isn't this great, now you don't have to worry about how many text messages you send, because everyone gets unlimited messaging!" (meaning, essentially, they removed the lower-priced, limited, options, and everyone pays the premium price for the unlimited messaging plan that you no longer need, because now 90% of your text messages are actually sent as iMessages) - smart way for the carriers to still get about the same amount of money from everyone, despite people no longer using one of their services.
