Follow this guide to replace the 5G mmWave antenna in your iPhone 16 Pro. This antenna is only in United States and Puerto Rico iPhone 16 Pro models (A3083).
You may need to replace the 5G mmWave antenna if your phone is having cellular connectivity issues but works normally on Wi-Fi.
You'll need replacement back glass and 5G mmWave antenna adhesive to complete this repair. For the antenna, you can use thin, double-sided tape as a substitute for the adhesive that usually comes pre-installed on the earpiece speaker.
