Apple has been working on its own modem chips, and they're expected to be in iPhones as early as next year.
While this won't mean noticeable changes to your iPhone's performance right away, it could lead to better battery life and more efficient wireless connections in the future.
The switch to Apple's own modem is part of their long-term strategy to control more parts of their devices and be less reliant on other companies.
However, this change won't be immediate; Apple will start with select models and take several years to fully transition to its new modem chips.
