Apple may use a region-based modem approach for the upcoming iPhone 18 Pro lineup, according to recently leaked prototype details. Instead of relying on a single modem supplier worldwide, the company is reportedly planning to use Qualcomm's 5G modem.
As per the reported plan, iPhones destined for the United States would use Qualcomm's modem, while models sold in other markets would use Apple's C2 modem. This would be yet another step in Apple's efforts to minimize its reliance on Qualcomm. The strategy has emerged from leaked engineering papers related to the prototype devices.
The reported split largely revolves around network compatibility. Currently, the US networks are using mmWave 5G, a high-frequency technology capable of providing extremely fast speeds in urban areas. This technology is supported by Qualcomm's modem, making it the optimal solution for the US market.
On the other hand, the C2 modem is expected to be based on sub-6 GHz 5G technology, which is widely used by the vast majority of commercial 5G networks. As mmWave technology is not widely adopted in other countries, there might be no use for Qualcomm components in global models.
The modem strategy reflects Apple's broader ambition to control more of its core hardware technologies. The company has steadily expanded its custom silicon portfolio, from Mac processors to wireless chips, and now appears to be extending that approach to cellular connectivity.
However, the released files suggest there may be even more changes to the hardware components. For example, Apple is apparently working on an iPhone equipped with a new Sony IMX905 primary camera sensor. iPhone 18 Pro will also get an A20 Pro chip with packaging changes.
Experts also suggested that this time Apple will add eSIM support to its Chinese iPhones instead of dual physical SIM cards. Should this suggestion come to pass, Apple will be able to standardize its iPhone range worldwide.
Looking ahead, Apple seems be taking a practical approach to modem development by avoiding a complete global transition, but rather leaving Qualcomm chips only when there is no way around them.
