Verizon phone withT-Mobile SIM card, mic cuts out?
This is less of a "how to fix this" question and more of a "has anyone heard of this" question.
A customer showed up with a Galaxy S5 that works perfectly in all regards (never been dropped, etc), except that occasionally the microphone will cut out during a phone call. She claims to have taken it to several places, including the Verizon and T-Mobile stores, and she is consistently being told that it is because she's using a Verizon phone on a T-Mobile network. She sent the phone back to Samsung and they sent it back with a new microphone, but also told her the old microphone didn't fail their testing.
I've never heard of such a specific issue is this, and I fail to understand how a carrier choice could affect the local hardware. Has anyone heard of this?
Is this a good question?
