> Cell phones were widespread in Europe before they become so in the US.
Are you using a small number of Western European nations as a proxy for all of Europe?
The US invented the mobile phone and deployed it very early on. 2/3 of Europe was too poor to afford mobile phones until the past 10-15 years. Eastern Europe only started getting widespread mobile phones with the rise of cheaper, high-function smartphones in the past five to seven years. The same is true in Russia.
The US matched most of Western Europe on 2G deployment, primarily lagging Germany, France and the UK. The US was far ahead of Europe on 4G deployment [1][2][3][4], and it's leading Europe on 5G deployment as well [5].
Western Europe's stumbles after 2G are why European tech companies have failed miserably to compete in mobile and the US de facto conquered that market in the West. It's why Apple today is a $2 trillion company (equal to 10 SAPs) and the old Nokia got killed off. Western Europe entirely squandered their brief 2G lead over the US.
