Perhaps the most overlooked new feature of the iPhone XS and XS Max is their Dual SIM Dual Standby abilities, after 10 years of deliberation. There have been millions of users, especially in Asia or Europe, carrying an iPhone plus another phone, just because Apple was saving this option for some future "S" year.

This time around, iPhones are probably going to explode in terms of market share in Asia and Europe, precisely on account of the Dual SIM feature, as it is a common practice there to use two numbers for various reasons, be they plan prices, or traveling abroad.
