Pros: cant think of any..
Cons: Every single bit of their company..
They also have crappy phones, the best one they have is the krzr which is what I have, and also the Hp pda phone.
Summary: We have been with cellular one for appx. 3years now, and my parents wont switch companies. I got in some serious trouble because the company screwd up bigtime! I downloaded THREE ringtones, and one wouldn't transfer so i tried the try again option, and uhm.. well i did the try again a bunch! of times and it still wouldn't transfer so i gave up. When the bill came around, it charged me for EACH of the redos which was Ridiculous! So, for that one bill alone, they had charged me over 400$ in downloads alone!
Which was insane! I now no longer have internet on my phone, Thanks alot Cellular One!!
