Sprint made the most upgrades, with $11 million in improvements made in 2008, meaning better reception and call clarity should already be a reality for local users.
Verizon extended their Texas network by adding an additional 179 cell sites throughout the state. They also installed 190 emergency generators meaning even in the case of a hurricane, many customers would still be able to get a call signal.
Finally, AT&T has announced plans to expand their network coverage in 2009 by spending $1 billion globally. Many of these upgrades will be not just for voice but data and internet functions.
Now the big question -- will these upgrades find their way onto your monthly bill? Will T-Mobile be announcing plans anytime soon?
