Phone 17 5G modems will be made by MediaTek, as Apple moves away from Qualcomm. Future iPhones will use Apple's solutions instead.

There's been a lot of fear in the last few days that Apple left off MagSafe off the iPhone 16e because it somehow interfered with Apple's C1 cellular modem, but physics precluded that from the start.

Per Apple, it's "the first modem designed by Apple." Given that all previous iPhones also had some sort of modem chip inside — for example, the iPhone 16 sports a Qualcomm Snapdragon X71M — it's easy to overlook the C1 as just another chip that makes the iPhone do basic iPhone stuff like connecting to the internet.
