text: i live in will cty, il, but i pay $4 per mnth in dupage cty cellphone tax. noone in cty ofc knows why. do you? i called sprint and they said even though i live in the will county part of naperville, i "show up in their system" as dupage county. i called both counties tax offices and they were totally clueless about it. they referred me to the equally clueless sprint. that is where the hub is set up for sprint. in that county. probably was before any set up for your exact area. check to see if the area has a newer tax for your area. you can do this by calling the public utility commisions in your area. you can also call sprint and have them fill out a complaint form to find out why you pay a county tax for a different county and they will get it straightened out with the puc for ya. chances are if the number was established long ago then it ran out of a different county sector. hope this helps.
