Robotic voice on brand new iPhone 15
(Posting on behalf of my mom) Very recently upgraded from iPhone 12 to an iPhone 15 because people I was calling were having trouble hearing me, my voice would cut off and turn robotic every so often for 30 seconds or so. Called the carrier and they do not have any answers, husband has an even older iPhone and no issues on calls with the same carrier. Upgraded the phone as I assumed that was the issue but issue is still happening. Switched from a physical SIM to an e-SIM and this did not help. At a complete loss here and wondering if switching to Android is the answer. Found an older thread with no resolve so wanted to ask again to see if there’s any new info on this seemingly common issue!
