Motorola EX431G User Manual

The problem is in your phone's earpiece. Take your phone back to the store where you bought it and have it replaced.

I chatted with Motorola, as I had this problem. Here is their response:

While on a call, press the center button(press the side only to the right) this will give you option to adjust the call volume of the phone......

So, the real answer is close. While on a call, you have to hold down the right outside edge, or ring, of the center key. While holding it down, turn up the volume button on the right side of your phone. It worked for me. Hope this helps!

Hey Bill. If you want to prevent accidental usage of data, contact your carrier and request that your data be disabled.

Hi Sue. This could be an issue with your carrier. Contact them and report the issue.
