Used Sprint. Never again. Two friends tried Sprint. Horrible coverage, even worse customer service. Never again.
Used Verizon. Sticking with Verizon. Good coverage.
Girlfriend uses Cingular. Poor coverage and more dropped calls compared with Verizon (I know because I'm on the phone with her a lot, med-distance relationship). In addition, if you start your call before 9pm and keep talking after 9, it continues to use your anytime minutes, NOT your night & weekend minutes!
Yeah, she got screwed over on that for several hundred dollars one month until we figured out why. With Verizon, you automatically switch to your unlimited night & weekends after 9:01pm, even if you stay connected.
I'm not saying Verizon is wonderful and a great company, cause they screwed me over charging me all these reactivation fees when we transferred our familyshare account from my dad's name to mine (same account, different name to bill to, but they CHARGED US to change who the bill went to on EVERY LINE and didn't say a damn thing about any charges to do that at the store. Found out when the bill came.
Bottom line is, cell phones are like politicians. You choose the best one you can (Verizon), but they all suck.
