news flash, 4g isn't available and stable in all areas.

if you are not in the darker areas that are shown on the map, then you wont have 4g coverage.
Although the map linked to above is generally correct, it's somewhat misleading. You'd be better going to
4G LTE Network | Verizon Wireless. This will bring you to a screen that looks like this;

.
You enter the actual physical address where you wish to determine coverage (lower left side of the page) and press the red "Am I Covered" button. Once the answer shows up, click on the red "View Coverage Map" button. This will give you a very accurate representation of where coverage lies for you and what type. You would probably benefit from zooming out a couple clicks on the negative (-) sign at the top left of the map. Anywhere that the color is DARK RED shows strong coverage in the 4G LTE areas. This is the fat Donut areas I was talking about. Anywhere that the color is RED, will be areas addressed by the 4G LTE Extended Coverage antennas. This is the Pancake areas I was talking about.
Here's a representation of my area and home (my house is the red pin in the middle - unfortunately). If you click on the PIC, you'll see it closer. In my case, the DARK RED 4G LTE (Donut) coverage area is to my East and South by only a few blocks. As I travel home daily I run up the road that's diagonal from the bottom right to top middle (Route 320). As I ride on that road, the 4G coverage is SUPERB since it's covered by the 4G LTE (Donut) Coverage antennas. I stream music in FLAC (Lossless Compression) in my car from my home PC at about 1MB/sec with no hiccups. Once I turn left off of that road and head into my small development, the coverage begins to fade. While driving through my development I am traveling DOWN HILL into a small low-lying area with a creek. As I get close to my street or just as I turn onto my street, the 4G signal disappears and the 3G takes over. Even though I am clearly in the RED 4G LTE Extended (Pancake) Coverage Area, my house and the others in my immediate neighborhood sit too low (near the creek level) to capture the signal from the 4G LTE Extended Coverage antennas, so the signal literally flies right over my house. I can stand on the roof and raise the phone above my head and get 4G (and yes, I've done it), but in the house, in the driveway and yard, on the street 40 feet below, no 4G.
Also, think of the coverage representations as LAYERS, where the 3G layer in LIGHT RED is essentially everywhere on the map above underneath the other coverages, then the MIDDLE RED is laid on top and finally the DARK RED is on top again, so where there's good 4G LTE coverage (DARK RED), you'll likely not see the 3G signal on your phone at all because it will opt for the strong 4G instead. That doesn't mean there's no 3G there and if you turned off the LTE radio, you'd get 3G. If you are in an area where the 4G LTE Extended Coverage is, the liklihood is you'll still get 4G, but it depends on how high (or low) of an altitude you are at - like my home. If you're in a low-lying area, you might still only get 3G. And finally if you're in an area where the 4G LTE or LTE Extended Coverage is non-existent, then you'll get 3G all the time.
I am waiting for Verizon to add a Donut 4G Cell Site nearer to my home, or for a manufacturer to sell a 4G LTE signal booster that will work with Verizon. Right now, only 3G signal boosters are available that work with Verizon. If I could get a 4G LTE signal booster, I'd only have to place the antenna on my chimney and run a line into my home, place the booster on an interior wall and I'd have 4G. But whether I have 4G in the home or not is MOOT, since I have a WIFI router. So not having 4G in the house isn't really a concern. For the most part, once I leave my immediate housing community (and I normally travel generally in the East - Southeast direction (towards and into Philadelphia), I have 4G all the time.
Try this yourself and you may start to realize that it's NOT THE PHONE in most cases.
