Tmobile vs Metropcs voice quality....?

[rshimizu12]

Does anyone happen to know if the voice quality is any better with Tmobile. I have Metropcs, but the voice quality is terrible at home. I am wondering if Tmobile uses a different frequency......? The voice quality of Metropcs is often unusable at home in San Diego 92107.

MetroPCS uses T-Mobile cell towers, so you'd have the same signal.
