iPhone 13 Pro Max EU – Top Left Antenna Function

Hi everyone,

Quick question: on the iPhone 13 Pro Max EU version (no Ultra Wideband), does the top-left antenna module (the one by the internal earpiece) handle Wi-Fi, 4G, and 5G, basically all cellular functions?

Thanks!

I found this and have found it useful on my iPhone 6 Plus.

To view detailed signal strength information on an iPhone, you can enter the secret code 3001#12345# into the Phone app and press the call button. This will activate "Field Test Mode," displaying a menu with various network and signal details, including numeric values and potentially graphs according to PCMag and ThePhoneLab.
