Sprint I pruchased a Sprint phone in March and was sold this idea of paying just $60 a month for their services including something called Data usage, and so I of course bought their service. Bronx Nationwide

I am a Sprint customer for my cellphone and ATT for Uverse and can tell you that taxes on utilities can be quite high b/c the city, county and state all want their share and that's not including any additional surcharges carriers tack on for complying with government mandates - so taxes could add an additional 15% to 25% based on your location. Looking at the numbers you provided it seems that expecting an $80 month bill was a bit unrealistic b/c the plan ($60) + the device ($24.99) was already putting your bill @ $84.99 not including taxes. If you add between $12 to $21 in taxes, you'll end up with a normal bill ranging from $96.99 to $105.99 - the first bill of $109 seems to be within that range based on partial charges. Sprint usually charges $36 for activating a new phone (unless it can be waived based on your employment or other promotions) which can take 1-3 billing cycles to post - the second of $143 seems accurate if you were charged the $36 activation fee on that invoice plus your "regular" charges of $96.99 to $105.99. I suggest reviewing the invoice to see how much you are paying in taxes and surcharges and then adding that to your "regular" plan of $84.99. Also, take into consideration that any additional services such as insurance will increase your base price. Best of luck!
