  1. Could it be simpler than this? Could 312250 be real-world testing--see which non-overlapping sites actually end up with substantial amounts of traffic on them to identify holes that these sites could fill? The thought just occurred to me, though if that were the case, then I'd expect to see 312250 everywhere at once, I suppose, with sites gradually filtered out rather than added in. - Trip
  2. And as long as they do that, then all will be well. I'm just not putting money on it happening. - Trip
  3. I rather like this idea, to be honest. 😆 - Trip

  5. No. I have, at present, three phones on active lines (AT&T via FreedomPop, US Cellular prepaid, and my main Sprint line) and three phones using SIMs solely to show LTE signal (Verizon E5 Play, T-Mobile E5 Play, and T-Mobile G4 Play). The two with this issue are in the latter group (which the third, the T-Mobile E5 Play, doesn't seem to have this issue that I've noticed), but they generally say "Connected to LTE" except sometimes when they don't. But yes, the statistics are updating. I tend to eyeball my phones in case, for example, the GPS stops updating, which has been less of a p
  6. Great! One other question I have is about the logging functionality. I've been having some issues with specifically my Verizon phone not logging things at times even though logging is enabled and both GCI and TAC are present. I added back one of my old G4 Plays to try to chase down the B26 312250/B41 T-Mobile while keeping my primary T-Mobile phone available for B71, but have had a similar issue there. I cannot be 100% sure, it seems that both of these phones will sometimes show correct and updating data but have "Connecting..." at the top right rather than "Connected to LTE." (Th
  7. Addendum: I got last night's OpenCellID data and it shows additional sites across the country with 312250, but the data is very spotty. Pretty sure I'm the only person in the DC metro area who has contributed 312250 data to OpenCellID based on what I'm seeing. The Mozilla Location Service data doesn't have anything for 312250 at all. I contribute there as well, so not sure where that data went. - Trip
  8. A few observations about T-Mobile's network over the past few weeks. 1) It looks like T-Mobile is making some type of change to the software configuration of the 600/700 panels, even if only one of 600 or 700 is actually deployed on them, such that each are getting new GCIs separate from the existing values. It seems to be happening in batches, as I've seen sites changing gradually over the past several weeks while passing through the same areas. As it stands now, some sites have up to six or seven (!) GCIs, the original for PCS, a slightly newer one for AWS, then a brand new one f
  9. 312-250 appears to be for sites that T-Mobile plans to keep that are not co-located with existing T-Mobile sites. I've seen something like 8 or 9 of them. I'm not sure how it should be displayed though; it currently is Sprint** which is not bad. I feel like it should be Sprint since it's not a site that's fully integrated yet... maybe it should be as simple as "Sprint Keep"? The one thing I would like is for the notes to follow from the associated 310120/312530 site onto 312250 and do the 0x1450 offset like 310120/312530 does. I've merged my Sprint and T-Mobile databases and so the Sprint
  10. If it's anything other than making the two networks appear native to each other, I'm not interested. - Trip
  11. Answered my own question. https://imgur.com/a/e1o4UlR Yes, by putting my T-Mobile phone on Band 26, I was able to force it onto 312250. When it should have handed off to the neighbor cell, it instead dropped to No Service. So I'm set to try to identify some keep sites. - Trip
  12. The obvious way to find them would be to find a way to lock my phone to the 312250 PLMN, but do you happen to know if it's being applied to Band 26 on those sites as well as Band 41? Because I could just lock my phone on Band 26 to achieve the same goal in that case. - Trip
  13. Amusingly, that would fit the bill. The site I connected to was definitely one that represents a gap in T-Mobile service on any band. I have no idea why T-Mobile wasn't on that building in the first place. If that is in fact the case, I'd be thoroughly interested to find out which sites fit are broadcasting 312250. Hm, I wonder if I can lock my phone to a specific PLMN... - Trip
  14. I think this is new. I have my T-Mobile phone locked on Band 41 to pick up sites with the new Massive MIMO gear. Until today, moving outside an area with T-Mobile Band 41 has always resulted in "No Service," but this afternoon: https://imgur.com/a/TCo2cs8 I'm not sure I've seen the 312250 PLMN before, and considering the phone has no service (just a never-activated SIM), it doesn't roam, so I'm guessing the phone thinks it's native. Any ideas what I'm seeing here? - Trip
  15. Looking at the map in this area (Fairfax County, VA), I see sites that I know do not have Band 5 LTE that are showing as having 5G NR. I need to check if PCS is now running on some of them, as I've not done that in a while. If it is, then PCS. If not, AWS. EDIT: In Richmond, they hold both the A- and B-blocks in 850 MHz. Pretty sure they're using 850 MHz there based on the far less defined coverage area, but I wonder if they're doing DSS at all and are, instead, splitting the spectrum. Maybe next time I'm down that way I'll take my spectrum analyzer and see what I can see. - Tr
