I'm fond of https://www.cellmapper.net/ for a more local view. It's helpful for answering questions like "why do my calls always drop when I drive into region X?" and "why is coverage shit in this area?", also "what cell carrier should I get if I plan to move to X?"

Great site, nice to see where the local towers are. I wanted to know what tower my phone was connected and this app gave me the Cell ID (CID) https://play.google.com/store/apps/details?id=com.wilysis.ce... which matched the map. Super cool!

Much of that info is also in the hidden field test menu on phones. On iOS, if you dial *3001#12345#* and hit call, you'll jump into a menu with a bunch of stats on the network. It's not the friendliest UI though, the one you found is probably better. Other phones likely have other numbers to call, but the field test menu is pretty ubiquitous (it's equivalent to the cable modem 192.168.100.1 page).

EDIT: escaping asterisks

Nice! I googled the Android version and it's *#*#4636#*#*

But the CID from that screen doesn't match the website, there must be some kind of conversion required.

Edit: also escaped asterisks

CID is displayed in hex so it needs to be converted to decimal first.

All I see is a blue void (tried two browsers) - do I have to click something?

Looks like it starts at 0,0 - zoom out on the map to find land

If your browser doesn't have your location for whatever reason, most maps will drop you into lon 0, lat 0, which is South Atlantic Ocean west of Africa.

I tried a bit of moving and zooming, but not enough I guess.

I really hate this, not that it's a bad default for location, but that it's a bad default for zoom.

Strava (running/cycling gps tracking app) has default zoomed all the way into San Francisco, so if you want to find anything you have to zoom out first. What they might thought is a little fun gimmick is annoying as hell.

I had to select a Provider on the left side before the masts starting showing up.

it gave me a very zoomed in view of what I assume is Null Island (GPS coordinates 0, 0). Zooming out several times eventually reveals map elements.
