Or two carriers, if they hit Sprint as well.
Verizon doesn't control or censor smartphone software. They allow anything to be downloaded and used, including Slingbox and VOIP.
You must be thinking of ATT control and Apple censorship 😉
actually, verizon has a universal policy of selling phones from ANY manufacturer with their own "red" tailored, overtly branded, and usually crippled OS.
ATT has no control over what is downloaded on an iphone, nor any "censorship". in fact, ATT has NOTHING to do with the phone itself, only the subscription.
verizon uses an irregular, outdated, obsolete technology and forces manufacturers to cede control over software and capability.
and verizon's CDMA phones don't play nicely with inter-network interoperability. international texts rarely work, long texts sent/received with GSM phones even in the states rarely work properly, while ATT/tmobile's GSM networks have no problem handling all that.
verizon's ONLY advantage is having more towers... but that is a smaller and smaller gap every day. ATT/tmobile, on the other hand, offer sim cards (pop in/out), GSM network (international travel/roaming), better future speeds, more devices (acquired from anywhere in the world, not just the operator).
