I've heard various complaints/grumblings about state and federal taxes on cell phone usage. Afterall, very few people are willing to give up the convenience of their smartphone in order to bleed the beast of another $2-$20 per month. But I recently stumbled across a way to avoid paying those taxes (at least directly) and still be able to use all my Android Apps.
When my last cell phone was stolen I signed up with Virgin Mobile prepaid because they had the cheapest phone/text/data service in my area without a contract. My teenage daughter also chose to change her service to Virgin about a month later.
I have been paying using Virgin "Top Up" cards which can be bought at local retailers (though I buy mine on line for a discount). When I buy these cards online I simply pay face value for them - $25 card for $25 (actually about 3% less online) just like buying a gift card. I'm not sure if local retailers charge sales tax. I then enter the code on the Virgin site and when my next monthly bill is due they deduct the $25 from my account.
Meanwhile my daughter (on the same $25/month plan) was paying with her credit card and was being billed $27.10/month. When we inquired about this, Virgin informed us that the extra $2.10 was taxes. Needless to say, she now buys Top Up cards as well.
I assume Virgin is still probably paying some taxes in our name, but it's the best we can do until "Liberty Mobile" goes live

Virgin has most of the latest phones available and uses the Sprint "phone lines" (or whatever it's called for cell service) so we've got great phones and coverage, just pay a lot less AND avoid the tax man.
Might be worth looking into a prepaid plan from your provider or switching to one like Virgin. The cards for all major suppliers can be found discounted online with a simple google search, or I can provide a referral link to my source to anyone interested.
NOTE: I have no association with Virgin or any other cell phone/service/card provider. Just thought y'all might be interested in reducing that tax burden a bit more.
