Mess up in MCC/MNC values?

There's a clearwire conversion site that was recently performed along my drive to and from work. I first noticed the huge deadzone where I would drop down to 3G and finally noticed the crew on the tower. It's been about 2 weeks since they've been out there, and I'm still having service issues. My phone shows full B41 signal strength, but the data is unusable. I have attached two screenshots from Field Test Mode and did some digging. The first screenshot is while connected to my magic box at work and it shows MCC 310 and MNC 120 which registers as Sprint. The screenshot while parked outside on the newly upgraded tower shows MCC 311 and MNC 940...which doesn't exist on https://www.mcc-mnc.com/ There is a listing for Sprint at MCC 311 and MNC 490 however. Could it be that a simple dyslexic switch of the value 490 with 940 has resulted in a dead tower?

Could be. There is a site in Louisiana where, after RRUS 11 -> 31 swap, they set the B25 eNodeB ID as 0x4BB68. You know, 310120...

It's still that way today, years later. But in that case, the site actually still works, so nobody ever noticed.

They've gone back and put the old antennas up, and it worked for like a day. They are still there, but it's back to a non-useable data area again. The signal is fine, which makes it worse because I have about a 5 mile stretch of my drive to and from work where I can't even stream apple music. I know two site managers for this area so I'll reach out to them if it's not fixed by end of next week.

    • Went to Rolling Loud NYC at Citi Field this weekend. Over 60,000 people in attendance. Verizon is a sponsor of the festival this year so naturally they had a ton of COWs set up at the festival. I counted at least 4. As a result, they were virtually the only carrier consistently able to provide a data connection. I didn't see any Verizon 5G, only LTE. T-Mobile on the other hand was a very interesting experience. I was seeing an eNB 331804 which I'm 99% sure is a COW. They also seems to be doing some sort of traffic management because I noticed that if I left my phone idle in my pocket, it would drop down to No Service/SOS or sometimes it would sit on EDGE. But the second that I needed to send a text, make a call, or even use Twitter my phone would switch over to LTE or 5G to complete the task. In an active data session, my phone would constantly flip between Band 2, Band 66, and Band 41. Sometimes, I'd catch myself on the COW and other times I'd get pushed over to eNB 875868, the relatively new Sprint conversion nearby. The network moved at a snails pace though. Where Verizon took about 15 seconds to load Twitter or send a pic, T-Mobile could take up to a minute to complete the same task. Here's some photos of the COWs I spotted. I think that the first two are Verizon and the one in the distance in the third pic is T-Mobile's single COW, not nearly enough for an event that size.
