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.

For example, in a congested network area, the A18 chip in the iPhone 16e can instruct the C1 modem to dynamically manage traffic, prioritizing your needs in real-time. If you’re trying to send a photo or video to someone, for instance, the A18 will tell the C1 to prioritize that network traffic over other data tasks.
