Easy. European Countries are so small, esp compared to America, and there is a ton of movement between them so need to communicate between countries was high. However, SMS between different country cell networks was extremely expensive for various reasons. However, data and data roaming was not. Since WhatApp is entirely data to cellular company, it caught on and network effect took over.
The fact that WhatsApp is also gigantic in large countries with no intermobility between them (Mexico, Brazil, Nigeria) would suggest that the only issue that mattered was the fact that ~2011, mobile carriers would charge insane rates for SMS.
For sure, but from what I understand, in some European Countries in 2011, SMS was free if your recipient was inside the country but cost if they were not due to tariffs and interconnect fees. Since Europeans do move between countries thanks to that European Union thing, it became a problem and WhatsApp became the solution.
Sure, other countries it might have picked up domestically thanks to high SMS prices but low data prices.
In addition to that, WhatsApp was available at the time on Symbian devices and Nokia’s S40 devices (I remember downloading Jar and Jad files for button mobile devices, and each update was free up to year then it was a dollar for a year)
Crazy! You made me remember i actually once paid for "something" when it comes to Whatsapp! Then they added somekind of disclaimer "will be a paid service xxxxxyyyy" but it never happened!
I think it was more or less “nag ware”. I remember clicking “no, later” multiple times in a row and they’d only ask like twice a year. I don’t think it ever stopped working for people who didn’t pay (afaik).
I am not sure this is true. European countries are smaller but they are not that small. The number of people sending SMS to a foreign number regularly is I guess not significant. Potentially it was easier for people working abroad to stay in touch with people back home. If anything like that, it would be more true that it's the cost of SMS within the country - it was always increasingly unlimited but not 10+ years ago, mine was I think 9 cents. If you had like a 1GB of data, then it was a no brainer to save the 9 cents.
Depending on your family/travel background, it's very possible you don't or don't enough to need WhatsApp.
We travel overseas but everyone we have met just keep in communication over Facebook.
All our family is in the United States. When we are overseas, we just use wifi calling to communicate back home or since most people have iPhones, iMessage/Facetime.
My brother is about distance of Moscow to Lisbon from me, still a free call since it's domestic.
