Apple used its own C1X 5G modem only on the iPhone Air and continued relying on a Qualcomm modem for the iPhone 17 and iPhone 17 Pro. Now, the company has all but confirmed that approach will change with the iPhone 18.
Apple plans to use its own cellular modems in more products
Apple’s long-term plan is to use its own cellular modems in more products, strongly suggesting that they’ll be in the iPhone 18 and the iPhone 18 Pro. The comment came from Arun Mathias, VP of Wireless Software Technologies and Ecosystems at Apple, during an interview with CNBC.
When asked about why the iPhone 17, 17 Pro, and 17 Pro Max don’t have an Apple modem, Mathias responded that the company was focused on what it needed for the iPhone Air. He added that the other devices are also great products, but the company will use its own cellular solutions in more devices. Here’s his full answer:
Well, we were really focused on what we needed for iPhone Air, and we have great products with iPhone 17 and iPhone 17 Pro as well. And over time, we will see Apple cellular solutions in more products.

In line with the rumors

Mathias’ answer wasn’t a surprise, as the early rumors about the iPhone 18 Pro have already claimed it’ll utilize Apple’s 5G modem. That would give Apple even more control over its phones, and it could lead to various improvements.

Apple has already used its own C1 modem on the iPhone 16e, breaking from its reliance on Qualcomm’s modems. Interestingly enough, Samsung provides the cellular modems for the Pixel 10 devices, but its own Galaxy S25 relies on Qualcomm’s modems. That could change with the Galaxy S26, if Samsung really decides to use the Exynos 2600 in it.
Not exactly a headline feature
Apple should feel happy about breaking up with Qualcomm, but unless there’s a technological leap or failure, most users won’t notice any difference in connectivity. That doesn’t mean the change is meaningless. It just means that I would be surprised if it brings any noticeable improvements for the common iPhone user.
