> paying for “N text messages per month” is precisely what people refer to as paying per message
Maybe I said it wrong, "N text messages per month" for me means "Pay us 10 EUR per month, send up to 5000 messages" for example. Doesn't matter how many you send, you pay the same.
While "pay per message" is "Every text message you send, costs 0.01 EUR". Maybe I'm using the wrong words, but that's how I understand it.
Most of the people who were "texters" (in my circles) were on plans offering the first way of paying, while hardly anyone was doing it the second.
Another important part, was that most telecom's had free SMS and calls if you were with the same company (and still do, AFAIK), so constant bickering about what plan people are on and why they don't change so it's free and yadda yadda.
Many people were already mostly texting for free at this point.
The rates people were paying back then were extortionate - like 60-90% profit margin. When WhatsApp launched, plans were 5-15 euros/month for 100-500 messages with ~0.15 per message for overages. So you might not count the bundle as a per text message, but it really is which you can tell by what happens if you send more than your bundle allowed. Compare that with WhatsApp’s $1/year for unlimited messaging and you start to see the pricing disparity.
Many people were not mostly texting free in 2009. I think you’ve got the timelines mixed up. That started changing towards the mid to late 2010s precisely because of internet-based chat apps on the phone and plummeting data costs making the telco’s SMS pricing plans insane.
The initial claim of "WhatsApp happened at a time when, in Europe, you paid for SMS." maybe was true in parts of Europe, but clearly not everywhere. People were mostly using the Facebook chat (not Facebook Messenger/Chat) already before Whatsapp started being used, although Whatsapp in Sweden still isn't as popular as in other countries. In Spain, everyone uses Whatsapp, in Sweden, seemingly the people I talk to only have Whatsapp to communicate with me and others outside the country.
> Many people were not mostly texting free in 2009
Most people I knew definitively were mostly texting for free even before 2009, again, at least in Sweden.
I grew up in Canada so my knowledge is purely from talking with people in non-Swedish parts of Europe that I met and also reading contemporary articles analyzing the space as well as retrospective analysis of what led to WhatsApp’s popularity and dominance.
