Great find! If you go to the online billing, does it list any upgrades to your plan, such as adding unlimited incoming calling for a certain price per month? Or alternatively, do you know of any different "levels" of SERO plans with different amounts of anytime minutes for different prices? The reason I ask is that I only have a cell phone; AND I use it for my job (in which I telecommute) so I generally have a lot of minutes per month. Right now I'm on a 1000 minute plan. That plan sounds AWESOME otherwise but unfortunately wouldn't work for me unless I could upgrade the minutes on it.
