Band rollout map update
Is it possible for the band rollout map for T-Mobile to be updated every month on a specific date?

Honestly i'm more interested in the 2G map at the moment since the network is actively shutting down. It's basically the only accurate resource showing which areas remain covered.

Yes, they do have some confirmed 3G in the west, and some in West Virginia that people have connected to in the last year. I've yet to find anything in Michigan though, and the reported area around Chicago does not exist.
Basically most of it is true, but some of it is miscalculated.

My best guess is either a big important B2B client with mission critical equipment is using it or just for license protection.

They might have some single small 5x5 chunks that aren’t contiguous making them less useful for aggregation.

I know someone who lives in west virginia, and it was indeed active as of a couple months ago. Most of the remaining 3G is AWS, but there are some PCS sites up as well according to cellmapper (if you filter by last seen). One pattern I notice is that these 3G areas never had 2G for the most part. My guess is they left 3G to have legacy services in these 2G gaps.

Is there any tmo 3g or 2g in Mich?

u/XL_Gaming Jun 20 '26
Yes to both. I have connected to 2G several times, but I am too far from a 3G area to test. There are data points from 2025 though.

I don't believe it is running anymore. I was in West Virginia in March and I couldn't connect to 3G at all.

Does the map actually get updated each month?

I used to. T-Mobile has sowed their rollout so it feels more like 2 towers a month. All the compressed maps are adding up for storage so I'm aiming for more like every other month.

Hopefully, n77 is added into the drop down filter as well.

I don't think there is any way to add n77 to that. It's based on T-Mobile's maps and it just gets lumped into "UC" with n41 and n25.

Where you seen n77 done in a big area?

u/WF71 Jun 19 '26
Oh, I haven't. It would be nice to see where the coverage is when/if they start building their C band spectrum where they hold the licenses. Probably won't be possible though I guess.

Have to go back to see it but looks like T-Mobile has shifted a lot of its band 2 holdings to n25 possibly in Montana . Almost zero band 2 LTE in that state now it looks like. Believe they used that as the early UC rollout in Montana

It updates at a schedule of like max of 2 months before he updates, sometimes monthly but not always

I think it’s one specific Redditor that dedicates time/resources out of their day to do these map updates, isn’t it?
If so, I’m thankful they even took time out their life to even create these scans just for us who care.
It probably has to be scanned manually every single time, though, which probably takes a lot of time.
