Stolen data from Apple supplier Tata Electronics suggests the upcoming iPhone 18 Pro will feature a split modem strategy. U.S. models will reportedly continue using Qualcomm's hardware for mmWave 5G support, while international versions will switch to Apple's own C2 modem. This distinction stems from a major cyberattack on Tata, exposing confidential manufacturing details.

The leak indicates Apple's C2 modem, codenamed Ganymede, still lacks mmWave capabilities. This forces Apple to rely on Qualcomm for the U.S. market, primarily driven by carriers like Verizon and AT&T who invested heavily in mmWave networks. These super-fast, short-range 5G bands are a carrier bragging point.

While the C2 modem is expected to be more power-efficient than Qualcomm's chips, U.S. buyers might experience slightly reduced battery life. Analyst John Gruber argues that the practical benefit of mmWave speeds is negligible for most users, suggesting carrier economics, not user experience, dictates this dual-modem approach.

This move represents a partial step in Apple's long-term plan to phase out Qualcomm modems. The iPhone 18 Pro series, including the Pro Max, is slated for a fall release, potentially alongside Apple's first foldable iPhone.
