Verizon FIOS and brought 2.4GB GPON FTTP (Fiber To The Premise) since late 2005, and Verizon has a few 10G installations in The East.
Bandwidth costs next to nothing as to what it used to and Verizon has consistently sold blindingly fast connections to anyone on their network for a reasonable price. (20 years ago 1.5 mbps could run 1000s a month).
While Verizon has been pushing the envelope, and has the ability to reclock or even up the speeds further still in their current configuration, ATT has milked its customers with crappy service, crappy prices, and slow speeds (max 24 up and 1.5 down) with a poorly designed and implemented network that is intermittent and doesn't get into the premise. (They run UVERSE over copper the last leg.)
The head of Verizon worked as a cable splicer before he was CEO and he foresaw the future and understood the value of the network, and...Verizon's network will remain rock solid and state of the art into the foreseeable future.
ATT, on the other hand, does what ATT always does...a shitty job, at high prices, with poorer customer service. Now, Google is forcing ATT's hand, because it's not just cable that can run circles around it, but, just about any network. (E.g. my Verizon 4G LTE hotspot goes MUCH faster than UVERSE.)
On the wireless side, Verizon's Iphone comes UNLOCKED, out of the box, and works on gsm, CDMA, UMTS, HSPA, and LTE....all out of the box...from day one, and...at 700mhz domestically (a superior frequency over the 2900 used by Sprint). A Verizon iPhone will work on virtually any network, anywhere. That can't be said of ATT, nor Sprint. You can read the spec yourself on apple.com. CDMA model A1429*: CDMA EV-DO Rev. A and Rev. B (800, 1900, 2100 MHz); UMTS/HSPA+/DA-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5, 13, 25)
ATT is one of those greedy icky companies that has repeatedly fucked customers over and over the years. Competition is the best thing for them.
There no excuse, other than quarterly dividends, for ATT not doing it right the first time, other than them being cheap, and fucking their customers.
