Interesting. My assumption was that Europe was much more okay with pay-per-use than the US was. It was always strange to someone in the US that a European would pay different amounts for a call depending on what kind of phone you were calling, where in the US both parties simply paid for their airtime if they wanted to use mobile phones.

SMS took off faster in Europe than in the US, but we've had bundled packages for so long that the individual cost per text wasn't such an issue, and now on many plans they're unlimited.

I guess the differing cost structure depending on who you're texting and from where may have spurred the adoption of WhatsApp, whereas in the US, even if you WERE paying per text, it was the same across a territory of many thousands of miles and hundreds of millions of people. And, the same way that many folks in the US do not even have a passport, they tend also not to have a reason to text internationally. The size and homogeneity of the country benefits the adoptions of some technologies, but hinders the adoption of others.
