Some interesting problems...

I have a Treo 600 with Sprint, and my b/f has a Nextel phone.

Most of the time, it sounds like he's talking RIGHT on top of the microphone, and it gives him a muffled sound. Or, I'll only get half of a sentence, like the phone didn't deliver the first half... a delay in transmission of some sort.

Sometimes the phone will go busy, as in a straight busy signal in my ear when talking. Or a recording will come on "your call can not be completed as dialed" in the middle of a conversation.

My dad has a TMobile phone. We have the muffled sounds problem coming from his phone. Many times it sounds like he's right on the speaker talking.

They say that I sound static-y, and that I cut in and out.

When I call land line phones, I never have any of the above mentioned problems.

Any thoughts??
