LOL, you may "care about facts" but you post nearly as much incorrect
information as nospam!
But I am willing to help educate you.
Coverage Differences Between AT&T, T-Mobile, and Verizon
<
https://tinyurl.com/ATVCoverageComparisons>
The Three U.S. Networks—They Are Not Created Equal
--------------------------------------------------
The U.S. has three nationwide carriers, AT&T, T-Mobile, and Verizon.
AT&T and Verizon evolved from legacy cellular networks over the years,
and built out a large network, acquiring smaller regional and rural
carriers along the way. T-Mobile was a PCS (1900 MHz only) network with
mainly urban coverage. All three networks work acceptably well in urban
areas. While no carrier has 100% geographic coverage if you plan to
travel to more remote areas, like National and State Parks, or if you
are going to be driving through rural areas, or if you’re visiting the
outskirts of urban areas (often called the “greenbelt”), then you’ll
want to avoid T-Mobile and choose AT&T or Verizon. Even non-tourists
that use T-Mobile as their main carrier often carry a second phone with
an AT&T or a Verizon prepaid SIM when traveling outside urban areas,
just in case of emergency.
<
https://www.fcc.gov/BroadbandData/MobileMaps/mobile-map>). You can also
use the interactive map at
<
https://www.whistleout.com/CellPhones/Guides/Coverage>. These are the
maps for each networks’ native coverage. If you sign up for postpaid
service directly from the carrier, you also get some off-network roaming
on smaller, more rural carriers, but the carriers’ prepaid services, and
their MVNOs (Mobile Virtual Network Operators), often do not include
off-network roaming (though sometimes they do).
What About “Free Roaming”
-------------------------
Some carriers advertise “free roaming.” But understand that when a
carrier touts "free roaming" it doesn't mean "free roaming on every
other carrier, everywhere, no matter what" (except for emergency 911
service).
You can look at the carrier's maps and they'll explicitly show where
roaming is available. For example, in the Death Valley Area, all the
carriers roam onto Commnet, see the T-Mobile map at
<
https://i.imgur.com/Ew4qf8I.jpeg>, but MVNOs usually won’t roam even if
their maps show roaming.
In California, there are only two very small areas where T-Mobile has
any roaming: in the far north there's a little roaming on U.S. Cellular
and in Death Valley there's roaming on Commnet. There is no longer any
roaming on AT&T or Verizon. If you are in an area where AT&T and/or
Verizon are the only carriers then you will not have any coverage on
T-Mobile. Nor will AT&T or Verizon roam onto each other, or onto T-Mobile.
The problem for T-Mobile is that their native coverage is very small in
rural areas but they usually only roam onto small rural carriers and not
AT&T or Verizon. You can see some examples of the vast coverage
differences in the maps below (all taken from the FCC maps).
In fact T-Mobile complained to the FCC that AT&T and Verizon were
gouging for roaming services while AT&T and Verizon insisted that since
they incurred the capital expenditures of providing more ubiquitous
coverage that they should be able to charge a lot for it. T-Mobile was
especially upset that AT&T and Verizon were charging T-Mobile more than
AT&T’s and Verizon’s MVNOs were being charged; AT&T and Verizon argued
that their MVNOs were not using roaming simply to fill in gaps in
coverage in areas that would be expensive to expand coverage to (see
AT&T, Verizon challenge FCC's data roaming ruling that sided with
T-Mobile | Fierce Wireless).
Checking Network Coverage—Use the Tools from the FCC and WhistleOut
Prior to signing up for service, tourists should ensure that the network
that they choose will provide coverage in the areas that they plan to
visit. The FCC (Federal Communications Commission) has a nice tool that
compares the coverage of the different networks. Go to
<
https://www.fcc.gov/BroadbandData/MobileMaps/mobile-map>. You can check
the various boxes for the different networks and see how much more of
rural areas that are covered by AT&T and Verizon versus T-Mobile. You
Checking coverage is important because foreign tourists to the U.S.
often want to visit not just big cities, places like State and National
Parks which are usually located outside of urban areas.
It often upsets T-Mobile aficionados when vast differences in rural
coverage are shown, but I feel that it's important to be honest about
the differences in networks since it's a matter of both convenience as
well as a matter of safety.
Network Speed, Coverage, and Quality
------------------------------------
"We're fastest." "No, we're fastest." "You have fake 5G." "Our 4G is
faster than your 5G." "We have the most 5G." “We have the most real 5G.”
“Your coverage sucks.” “No one needs coverage in Podunk, Idaho.” “You
get free tacos if you choose us.” “We have the happiest customers.”
I received an email requesting that I add information regarding network
speed. Rather than parrot the absurd and conflicting marketing claims of
the carriers, I am adding the results of the most recent independent
surveys.
I added several examples of coverage differences because often there are
“fanbois” of a carrier that will insist that “all carriers are created
equal,” and get very upset when anyone points out any coverage
differences. Some fanbois insist that foreign visitors would be unlikely
to ever go outside of urban areas, where coverage is usually okay on all
carriers, but the reality is that foreign visitors often want to visit
places like state and national parks. So I’ve included a bunch of
examples of coverage differences that I’ve personally experienced.
• One area that I go through often is the Sierra Nevada mountains on
California State Highways 88, 4, 108, and 120, and the FCC map
highlights the very large differences in coverage in those areas; here
is a map comparing coverage in the central Sierras, a popular area for
tourists with National and State Parks, ski areas, and other recreation:
<

• One area we visit frequently is the southern part of San Mateo County.
In my younger days I used to do a lot of bicycling in this area, now
it’s more hiking and road trips. Verizon has the best coverage of
course, but surprisingly T-Mobile beats AT&T in the town of Pescadero (I
recommend Duarte’s restaurant). Sadly, T-Mobile doesn’t even have
coverage on the major state highway, 84, between La Honda and the coast.
See <

• Another area I go through often is the San Mateo and Santa Cruz coast
on California Highway 1; here is a map comparing coverage in that area,
where Verizon is superior, AT&T is a distant second, and T-Mobile an eve
further distant third: <
https://i.imgur.com/QOqnAVP.png>.
• A very popular route for foreign tourists is the coastal road between
Los Angeles in San Francisco; here is a map comparing coverage in the
popular Big Sur area (bottom left): <
https://i.imgur.com/ataZAOP.png>.
• The Pacific Northwest, (Northern California, Oregon, Washington, and
especially the coastal areas) is another popular destination for
tourists; here is a map comparing coverage in Oregon:
<
https://i.imgur.com/qX5rz0Q.png> where you can see the vast differences
in coverage, in the inland areas but especially along the coast.
• Someone on Reddit/NoContract inquired about service in Montana so I
added that map set as well, see <
https://i.imgur.com/Jk6XmCs.jpeg,
• Yosemite is a place we visit one or two times per year, often staying
in the “Yosemite West” area (technically outside the park boundary but
you have to go into the park to get there). One time we arrived in a
snowstorm and the key to our lodging wasn’t left out. Thankfully I had
Verizon service so I could call the management company. AT&T and
T-Mobile have no coverage (Sprint used to roam on Verizon, but no more).
Verizon had acquired a small regional carrier, Golden State Cellular
upon which they used to roam. See <
https://i.imgur.com/9zJhPUq.png>.
• An example of the the San Francisco Bay Area’s “greenbelt,” up to the
northwest corner of Marin County and Point Reyes National Seashore
(highly recommended), is at <
https://i.imgur.com/BCRhffC.png>:, you can
see the gaps in coverage on AT&T and especially on T-Mobile.
• Muir Woods is another highly-recommended tourist destination in Marin
County and you can see how poor T-Mobile coverage is in that area, see
<
https://i.imgur.com/QTPgy8j.png>:
• This is part of the Santa Clara and Santa Cruz Counties’ greenbelt,
and again you can see the big advantage in coverage enjoyed by Verizon
subscribers, see <
https://i.imgur.com/1w58JJA.png>
• Here is the area around Pinnacles National Park (highly recommended)
<
https://i.imgur.com/HevfvTN.png>:
• Someone I know lives in one of the mountain communities of the Santa
Cruz Mountains. I did a comparison of that area. You can see the huge
advantage of Verizon, and how poor T-Mobile is at
<
https://i.imgur.com/t8t7Xy2.png>:
• I grew up in South Florida, and still visit, so coverage there is of
interest to me, see <
https://i.imgur.com/SoWWEk8.png>.
• Someone mentioned that their children were hiking between Loma Prieta
Peak and Mount Madonna so I did the coverage maps for that area, see
<
https://i.imgur.com/0Nn3C2P.png>. You can see how tremendously better
Verizon coverage is in that area. It’s especially important to have
coverage when in areas away from roads. At the very least take along a
phone that’s on a prepaid Verizon service.
• A huge park in Santa Clara County is Henry Coe. You can see the big
differences in coverage at <
https://i.imgur.com/g61Ss5T.jpeg,though even
Verizon doesn’t have complete coverage.
