"Profit" is hard to measure. This may be good enough:
Verizon Wireless FY 2011
http://www22.verizon.com/investor/app_resources/interactivea...
Segment operating income margin 26.4%
Segment EBITDA service margin 44.8%
Verizon Wireless 1Q 2012
http://www22.verizon.com/idc/groups/public/documents/adacct/...
Operating Income Margin 28.6%
Segment EBITDA Service Margin 46.3%
Interesting things I also learned from this report:
- Verizon wireless is 55% Verizon, 45% Vodafone
- $52 ARPU (average revenue per user per month)
