CellMapper for iOS

67 Upvotes

Official CellMapper for iOS App

We have been planning to make an iOS app for some time. However, due to restrictions in API usage for cellular information, we are unable to make an app that competes with the Android one in terms of features.

That being said, we have built an early initial app to make the map more easily accessible:

https://apps.apple.com/us/app/cellmapper/id6761035253

We will continue to see what we can add to the app to get network information from the iOS device and to make it a bit more polished than simply using the the website. So please bear with us as this v1 of the app is simply the beginning, not the end state of the app.

Fake App Warning

Also, one reason we have released the app so early is due to a fake CellMapper app confusing users and tricking them into paying money to view some dubious coverage data not relating whatsoever with our crowdsourced data. We have recieved a number of tickets asking for refunds for the app which we have nothing to do with.
Please be aware that the fake/scam app is also called "CellMapper" on the iOS app store. We encourage users to report the fake app (which we will not link to in order to avoid SEO) to Apple (reportaproblem.apple.com).
We are in touch with Apple about the issue, but it still has not been resolved.

New "Contributor" user tier

25 Upvotes

Contributor user tier

Recently, you may have seen an arrow (➶) next to some usernames, similar to how premium users have a star. This is a brand new user tier we have created in order to recognize users who contribute data and tower information on a regular basis.

What are the benefits?

In short, the main benefit is an ad free map for our regular contributors. We'll look into more benefits in the future once we ensure the right contributors are flagged as we work on this feature.

Definitely not Verizon.

I could not even get a speed test to load with 100 MHz of N77 5gSA.

Local Verizon tower finally active

Thumbnail

18 Upvotes

After months of just waiting for the site to turn on, they activated the fiber for the site, and appears to be broadcasting all Verizon bands(LTE 2,5,13,66 & N77). By the speeds, this site is definitely not optimized yet , but we will have to wait and see what better speeds the site can give. Site is located at 1293 Old Union Church Rd. I’m guessing 1 gig backhaul. This site isn’t mapped on cellmapper yet.

I decided to try out spectrum mobile free for a year to compare it to my AT&T line. Here is them both in my living room. Note the AT&T tower is 0.1 miles from me while Verizon is 0.9 miles from me.

Can anyone figure this out? All of the roads around this new construction tree tower are closed at the moment so I could only get this view. Pretty sure it is not turned on yet.

Looks like some Verizon MVNOs and AT&T will be getting VoNR with iOS 27

Note20 5G SA Capable on T-Mobile

Post image
17 Upvotes

As a long-standing Verizon customer, I just didn't believe that my Note20 5G (SM-N981U1) was NR SA capable. All the sources kept telling me that only S21 series and later were NR SA capable. Doing a T-Mobile test drive right now and apparently this phone is NR SA capable on T-Mobile. Calls work and texts work while enforcing NR only. Here's a screenshot from the phone info screen: image Always knew this phone was best suited for T-Mobile 😅 (also has n71 but not n77)

Dumb Question, Deadspots

7 Upvotes

Sorry if this sound dumb, but can anyone explain how does dead spots happen, places like Walmart, Car wash Bank Drive thru, you get full signal or 2-3, but you don't get cellular data, as soon you move a block, your data starts working again, it makes me confused why this happen, I'm familiar with my home WiFi, I would get 6ghz in living room, where my router is placed , 1.8gig, and if I move further like going to a room, my phone would switch to 5ghz and I get Almost gigabit, but how in cellular side, does trees, brick building and houses, makes tiny dead spots, when the tower is not even far, like 1-2 mile radius

Verizon B13-Only Towers in Central MO

Thumbnail

28 Upvotes

Does anyone know why Verizon has so many of these old, un-upgraded b13 only towers in Central Missouri along fairly large highways such as US-54? They have just now started to upgrade them, and recently converted a few to modern hardware with AIR 6419s and AIR 3283s. The majority are still in the original configuration, though.

The situation seems to be unique to this market, and they are also all a specific type of tower: fairly short, self-supporting lattice or monopole, b13 only with ground-mounted radios, and a specific type of antenna platform with the antennas mounted from the middle. Other carriers have modern sites along the same highways on more normal looking, often taller towers.

Were these former LTEiRA towers that never got upgraded, did Verizon have issues with getting fiber backhaul, or something else? I don't think it is zoning related as they are in rural areas. I am curious why they are both unique looking compared to the rest of MO, and so lacking in upgrades. In other rural parts of the state Verizon may not have added n77 to all of their towers, but the majority had at least band 66 if not 2 and 5 added sometime in the last 10 years.

AT&T is the only carrier covering this area, Verizon has no service and T-Mobile uses domestic roaming

Note: I've heard that there may be structural issues with the tower (it's a locally owned site)

Speeds: Usually get around 15-30Mbps down and 5-15Mbps up on QCI6

Coords: 42.507298662816034, -72.70656763117807

My guess is old Verizon with LTE. Can someone confirm? Location is: 35.48229° N, 82.73921° W and I think it is LTE eNB ID :452720(2,5,13,66) + 152720(5,13).

What is this?

3 Upvotes

Saw this in person the other day, and had no idea what it was. The dish says "Verizon" on it, but I had no Verizon signal here. Phone showed Emergency Calls Only, but where this was, I'd doubt there was an ATT or T-Mobile tower within reception distance either, but not positive about that. It has 2 poles with some antennas on it adjacent to the dish unit.

Note - label says "Popular" but I think that's a typo as this is in Poplar, NC.

Catalina Island Cell Service?

22 Upvotes

Who has the most towers on Catalina Island, CA? I was just there on T-Mobile yesterday and the service was really bad there. Slow speeds in the main town center of Avalon CA, and very poor coverage outside the main city center, as if they only had one cell tower covering only the main downtown area. Had me thinking about who really has that island covered best?
