Only yesterday did I call the last seven days “a week of major profits“, and now here’s Verizon Wireless to bask in some investor goodwill as they announce their own impressive Q4 2007 performance. Adding two-million net customers with “industry leading customer loyalty” (or in other words a churn rate of 1.2-percent) and data revenues up a massive 53-percent, Verizon showed a 13.3-percent increase in total wireless revenues.

Interestingly, Verizon are still $31.2bn in debt, but they did manage to pay off more than $5bn in Q4 as well as buy back $1.1bn of their own shares; they’re still the most profitable of the US wireless networks and have the largest number of subscribers, at 65.7 million. More than 350 million people were living in an EVDO-enabled area by the end of the quarter, although only 35 million of Verizon Wireless’ subscribers have mobile broadband-enabled devices.

With 45 billion text messages sent, 927 million picture/video messages, and nearly 30 million music/video downloads, it’s little surprise that average monthly revenue per user (ARPU) increased by 1.4-percent to $51.49, with $11.06 of that being data fees.
