<p><strong>TL;DR.</strong> It depends entirely on the band. Low-band 5G reaches several miles and passes through walls. Mid-band, the C-band and 2.5 GHz spectrum most people mean by "real" 5G, reaches roughly half a mile to a mile. mmWave reaches about 500 feet and stops at a window. Finding a 5G tower near you matters far less than finding out which band it carries.</p><p>Every carrier markets all three as 5G, which is why a phone showing a 5G icon can be slower than the 4G it replaced. Low-band 5G runs on repurposed 600 MHz and 850 MHz spectrum and delivers speeds in the same range as LTE. The distinction is not marketing pedantry: it is the difference between 50 Mbps and 900 Mbps at the same address.</p>
Several miles of reach, passes through walls, speeds broadly comparable to LTE. This is what covers most of the US map.
Roughly half a mile to a mile. C-band and 2.5 GHz. This is the band worth having, and the one carriers are still building.
About 500 feet, blocked by glass, foliage and your own hand. Stadiums, airports and a few downtown blocks.
iOS and Android show 5G for all three. Field Test mode on iPhone reports the actual band; the icon never does.
<p>Across the United States the FindTower database holds 8,358,147 cell records from 17 network operators. T-Mobile accounts for 2,703,805 of them, AT&T for 2,694,558, Verizon for 1,225,037, and the legacy Sprint network for a further 1,612,971 now folded into T-Mobile. US Cellular adds 75,052.</p><p>National totals settle nothing about your street. Density varies enormously between a city block and a county road, and the carrier that leads nationally frequently trails locally. Check the coverage map for your own city rather than reasoning from a national number.</p><p class="ft-caveat"><em>A cell record is one transmitting sector, not one mast. A single tower commonly carries three sectors per band per carrier, so these counts track how densely a carrier transmits rather than how many structures it owns.

2,703,805 cell records, plus 1,612,971 legacy Sprint records now integrated into the same network.
2,694,558 cell records across its primary and secondary network codes.
1,225,037 cell records. Fewer records does not mean worse service where you live.
75,052 cell records, concentrated in the Midwest and rural markets the national carriers thin out.
<p>Higher frequencies carry more data and travel less far. mmWave is stopped by ordinary window glass, and mid-band loses significant strength through exterior walls, so a phone that shows mid-band 5G on the sidewalk can fall back to LTE in the kitchen. That is the physics, not a fault in the network.</p><p>The practical fix is position rather than equipment. Move toward the window facing the tower, and use the tower bearing rather than guessing. If the nearest cell is two miles away and behind a hill, no amount of walking around the house will help, and a booster with an outdoor antenna is the only thing that will.</p>

It depends on the band. Low-band 5G below 1 GHz works several miles out and through walls. Mid-band C-band and 2.5 GHz reaches roughly half a mile to a mile. mmWave above 24 GHz reaches about 500 feet and is blocked by glass, so it only works within sight of the transmitter.
Because low-band 5G runs on repurposed LTE spectrum and delivers similar speeds, sometimes slightly lower on a congested cell. Your phone shows the same 5G icon for low-band, mid-band and mmWave. Only mid-band and mmWave deliver the speeds 5G is marketed on.
By cell records in the FindTower database, T-Mobile leads with 2,703,805 across the United States, followed by AT&T at 2,694,558 and Verizon at 1,225,037. A cell record is a transmitting sector rather than a physical mast, and national totals say little about any one address.
Yes. FindTower plots recorded cells around your location and gives the bearing and distance to each. Carrier coverage maps show predicted signal rather than transmitter positions, which is why the two rarely agree at the edges.
No. Buildings, terrain and foliage attenuate higher-frequency 5G heavily, and a cell 500 feet away behind a brick wall can be unusable while one a mile away with line of sight is fine. Direction matters as much as distance.
