Apple is expected to take another significant step toward hardware independence with the iPhone 18 Pro lineup, as leaks suggest the company will deploy its second-generation C2 5G modem in global models while introducing enhanced satellite connectivity and efficiency improvements.

The anticipated September 2026 launch of the iPhone 18 series has generated considerable speculation, with reports pointing to notable advancements in connectivity, performance and battery life for the Pro models. While Apple has not commented on the unannounced devices, industry leaks provide an early outline of potential features.

Central to the rumors is Apple's continued push to replace Qualcomm modems with its own silicon. The C2 modem, following the C1 introduced in earlier models, is tipped for international variants of the iPhone 18 Pro and iPhone 18 Pro Max. U.S. models may retain Qualcomm's Snapdragon solution to maintain mmWave 5G support, according to supply chain information.

This dual-modem strategy reflects ongoing technical and regulatory considerations as Apple develops fully in-house wireless capabilities. Developing proprietary modems could enable tighter integration with the iPhone's hardware and software, potentially improving power efficiency, signal performance and long-term cost control.

The C2 modem is also linked to expanded NR-NTN, or New Radio Non-Terrestrial Networks, support. This technology could extend beyond the current Emergency SOS via Satellite feature — introduced in earlier iPhones for remote areas — toward more seamless connectivity. Reports indicate the capability might allow automatic switching between cellular and satellite networks, benefiting users in low-coverage zones such as remote trails, oceans or disaster-affected regions.
