Leaked internal Apple code discovered through a Kernel Debug Kit suggests that the upcoming budget-oriented iPhone 17e may be equipped with a C1-series cellular modem, marking one of the first models to use a modem designed entirely by Apple. This move would further reduce Apple’s reliance on Qualcomm. However, the leak also reveals a surprising detail: the device may not include the N1 wireless chip responsible for Wi-Fi and Bluetooth functions.
According to the code, Apple is currently evaluating whether to use the C1 or the upgraded C1X modem for the iPhone 17e. Reports from overseas outlets such as The Information align with this finding, suggesting Apple is more likely to opt for the C1X variant. The C1X is believed to be an improved evolution of the C1 modem first introduced in the iPhone 16e, offering better data performance and improved power efficiency.
One notable point of concern is the apparent removal of the N1 chip. If confirmed, this would mean the iPhone 17e may not support Thread, a wireless standard commonly used for smart home connectivity. Despite adopting an in-house modem, this limitation highlights Apple’s ongoing strategy to clearly differentiate entry-level models from Pro variants, particularly in terms of advanced connectivity features.
On the higher-end side, internal code related to the iPhone 18 Pro suggests Apple has not yet finalized its modem choice. References point to both the C1X and a next-generation C2 modem as possible options, indicating that a decision had not been locked in at the time the debugging tools were created. What does seem consistent is that Pro models will continue to include the N1 chip to ensure full connectivity capabilities.
Apple’s move toward developing its own cellular modems represents a major strategic shift that is beginning to show tangible results. The company appears to be testing these modems first in more affordable models, such as the iPhone 16e with its C1 modem, before expanding to other devices. Early performance evaluations reportedly show promising results, particularly in terms of stability and battery efficiency.
As all of this information is based on leaked internal code, final specifications could still change before release. Current expectations point to the iPhone 17e launching in spring 2026, while those waiting for the next flagship, the iPhone 18 Pro, may need to wait until later in the year.
