Verizon

Consistently under 1mbps for download and upload speed. I've been running speed tests since March. I get 75mbps around Stockton, CA, and 68mbps in Los Angeles, CA, so it is not my phone. Service use to be great but now horrendous. Pretty pathetic for Silicon Valley. Paying 100% for less than 5% of service.

Near Cupertino library, 90% percent of international call var Skype or Google hangout dropped. Very poor wireless coverage, ironically it's the Hq of Apple, an area with highest expensive power.

Only used voice, but at least I got 3 or 4 bars and didn't drop the connection. So far so good.

Signal is consistently poor. Hard to make or place calls. Very unreliable out this way.

I had Nextel which eventually turned into sprint. At the beginning ( about 3-4 years ago it was good), now I'm always on "extended network" with 1-0 bars, forget about watching a YouTube video and sometimes I need to make 4-5 calls to finish a conversation with a customer( I own a plumbing business). They keep saying "we are improving our towers, in two weeks everything will be back to normal". I've been hearing that for months now. It sounds like a company that is preparing to shut down and they are trying to stretch their short life for as long as possible, so when the are bought out, they can show they have thousands of clients and get more for their downhill going company. My contract ends the 28th of this month and I'm switching to verizon.

Terrible! Calls are always dropped after only a few seconds. And I cannot hear what the other person says - I can hear them for 1 second then followed by 4 seconds of silence. Sometime it's impossible to call out too. So frustrating! The problem is same inside my apartment or outside in the middle of the street.

ATT&T coverage is terrible to non-existent. It's often impossible to make a usable phone connection. I'm have to switch carriers.

Verizon coverage works really well anywhere I've been in the San Jose area (usually constant 4 bars and fast download speeds), as long as I'm at least a mile north of Willow Glen. Unfortunately, I live in Willow Glen and get maybe 1 bar at best and rarely get a consistent data link, even when I'm outside.

The Sprint coverage maps for my area all say best all green, the actual is yes spotty voice coverage, spotty 3g and not 4 g even though the maps say best or great coverage. So this means Sprint is legally running a scam on all of us. All Sprint users complain but stays becuase the others Verizon and AT&T or most expensive. Sprint users are cheap or trapped in a contract. Yes me too cheap. So when Sprint raises prices on worst coverage we get stuck cuz Verizon and AT&T will raise prices as they have the undoubtedly best coverage everywhere. I know I used to use ATT and Verizon when my employers paid for my phones. Now that I pay for the phone I went with the cheapest solution. Oh well Sprint sucks everyone knows it and they are allowed to lie about the covererge. I suggest you pay more for better coverage at Verizon and ATT! Or get cheap monthly rates with worst covergage with Sprint. Theres is a reason why Sprint is cheap, poorly run company, poor services, low prices... .

Reception is horrendous. A lot of new construction going on around Valley Mall, residential AND commercial. AT&T is going to have a lot of unhappy customers new to the area if they don't improve it soon. It boggles the mind that construction for the new Apple Headquarters is going on just across Hwy. 280 and AT&T hasn't done a thing.
