I have just changed my phone from EVRC TO EVRC-B. I did a little sample test and the voice quality seems better. It is also more comfortable for me to talk as I get a more flat tone in the earpiece (ears are sensitive). My question is will this effect my reception in difficult areas? I am a noob to all this but from what I have read it is just compressing the original signal so it seems like it would be the same but I would appreciate any input. Also what advantages or disadvantages would 13k bring. Again, from what I have read it uses more bandwith so it seems like it might effect reception. Reception is really a key for me since my cabin is in a very spotty reception area so I want to get the best possible. I have done the searches but cannot come up with the information I need. Thanks! PS love the phone. My incredible is being shipped back!
