I am having the same problem on my iPhone XS. My mom had the same problem on her X. We are both erizon customers.
The noise occurred on my Mom’s phone while on a trip to Huntsville Al on March 4. It happened on my phone while at home in Los Angeles on March 8
Hi, Magicball! I'm really glad that you reached out to us here! Do you have the most recent operating system update on your devices? Also, does this shrill, nasty beeping sound happen when your device is on speakerphone too? Next time, please take a speed test at www.speedtest.net to determine is signal strength has anything to do with it, okay?
