A leaker revealed the details about Apple's refreshed 5G modem coming next year, which will be the C1 successor.

Apple debuted its custom-designed C1 modem in the iPhone 16e last month, as part of a multi-year plan to transition away from Qualcomm

Based on information from a prominent industry analyst, Apple kept mmWave (millimeter wave) 5G support out of its in-house designed C1 modem for a good reason: power efficiency.

Daring Fireball ‘s John Gruber today says the answer is “no,” as he spoke with an Apple representative who confirmed that the new iPad Air and entry-level iPad models are not equipped with the C1 modem. Plus, MacRumors has viewed FCC documents that show that cellular models of both new iPads are equipped with a Qualcomm modem.

Macworld Almost hidden within the announcement of the iPhone 16e, Apple dropped something of a bombshell: It is producing its own 5G modems now. This has of course been rumored for a long time, and has frankly taken longer than expected;

During the Mobile World Congress 2025, Qualcomm unveiled its new X85 5G modem with an integrated 5G AI processor and called out Apple's C1.

As reported, Apple's manufacturing deal with Qualcomm for 5G modems is set to last until 2027, so there's still a lot of time left for Apple to continue to use Qualcomm's modems i

In many ways, the Apple C1—its first cellular modem—is the company’s most important product in years. Just as the company broke free from reliance on Intel with its own Mac processors, it is now breaking free from reliance on Qualcomm for cellular connectivity. Ditching Broadcom for its own Wi-Fi and Bluetooth is said to happen this year, too.

A new report from analyst Ming-Chi Kuo claims that it will be 2026 before an updated version of the Apple C1 modem with mmWave will enter mass production.
