Apple has underplayed the introduction of its first in-house cellular modem chip in the iPhone 16e, but future versions could be incorporated into the A-series chip, and even M-Series down the road.

At the heart of the system, the C1 (Cellular 1) chip first appears in the iPhone 16e. It is also expected to debut in other Apple devices in the coming months and will likely see use across all or most of the iPhone range by this time next year. Apple calls it “the most power efficient modem ever in an iPhone.”
