And I noticed that Apple C1 skipped 3G network entirely. Only has 2G,4G and 5G support.
I imagine the 2G network they are talking about is GSM, which is a 2G open standard created in the EU and used internationally.
> It was first implemented in Finland in December 1991. By the mid-2010s, it became a global standard for mobile communications achieving over 90% market share, and operating in over 193 countries and territories.
The iPhone 16e Tech Specs page lists 3G (UMTS/HSDPA) support. It's missing CDMA, but they already dropped that way back with the iPhone 14
