I find it mostly to be carrier and what area I'm placing the call from. This applies to reception too. At office and home I have about a dozen cell phones and all seem to be neck and neck about reception. Can't tell the difference. (The office does android apps so I get to try a lot of phones.)
Scroll though http://www.amazon.com/Best-Sellers-Cell-Phones-Accessories-Unlocked/zgbs/wireless/2407749011 and skip the under 89 dollar models.
Looking for a cell phone that would fit in a pocket and has great call quality. Seems good reception and call quality very hard to find according to the reviews I've read. I'm currently on Att so I assume anything GSM would be compatible. Thanks in advance!
