Apple is reportedly set to feature its C2 5G modem across all iPhone 18 models, a significant expansion from previous speculations that suggested the in-house chip would only be included in the Pro variants. This development is part of Apple’s strategic shift in its 5G modem approach, with the C2 slated for mass production using an older manufacturing process from TSMC next year. This differs from the processes used for the A20 and A20 Pro chips and aligns with Apple’s plans to unveil new products at its annual event, reflecting an evolving approach to modem chip integration.
Apple’s Push for In-House 5G Modems
Apple’s long-term goal has been to develop its own 5G modems, reducing reliance on third-party suppliers. The C2 is the latest in-house 5G modem, following earlier iterations in Apple’s chip lineup. This move is part of a broader evolution in Apple’s 5G modem chip strategy, which has been showcased during product unveilings at its annual events. Digitimes reports that this strategic shift is part of Apple’s ongoing efforts to control more of its supply chain and hardware components.
Expansion to All iPhone 18 Models
Contrary to earlier rumors, recent reports suggest that Apple’s C2 5G modem will feature on all iPhone 18 models, not just the premium versions. BGR highlights this full-line adoption, which could potentially ensure performance consistency across the iPhone 18 lineup. This rollout represents a significant milestone in integrating proprietary modem technology universally, further cementing Apple’s commitment to in-house development.
Earlier Rumors Focused on Pro Models
Back in March 2025, rumors suggested that only the iPhone 18 Pro models would feature Apple’s C2 modem. MacRumors and GizChina both reported on these speculations. However, the latest reports indicate a shift from Pro-exclusive to all-models inclusion, marking a significant change in Apple’s strategy.
Manufacturing Process for the C2 Modem
Apple’s next in-house 5G modem, the C2, will reportedly use an older manufacturing process from TSMC next year. This contrasts with the newer processes employed for the A20 and A20 Pro chips in Apple’s lineup. Wccftech suggests that potential reasons for choosing an older TSMC process could include cost or yield optimization for the C2.
Strategic Evolution in 5G Integration
Apple’s 5G modem chip strategy is evolving, with transitions from external partners like MediaTek to in-house development. Digitimes reports that annual product events have played a key role in revealing advancements like the C2 modem. This strategic shift has broader implications for Apple’s supply chain and innovation timeline for future iPhones.
Potential Performance and Market Impacts
The integration of the C2 modem across all iPhone 18 models could enhance 5G speeds and efficiency, leveraging the benefits of in-house design. This differs from prior rumors that suggested a focus on Pro models, thus providing wider user access to improved 5G performance. Market reactions to Apple’s full commitment to proprietary 5G tech in the iPhone 18 series will be closely watched, as this could influence future strategies in the smartphone industry.
