Thank you, now I know what to look for.

You have to know what is common for your area. I pretty much see 40978 and now 41176 in my areas but I have found 4137x in Madison Heights and Troy. I cant remember the different earfcn I found in Kalamazoo. Point is that 40978//41176 are not necessarily constants. Know your area.

OK Michigan peeps... Weirdest issue! We have a bunch of phones that can't connect to LTE. I have a ticket out there on my site with Sprint but its been sitting with Field engineering for a while with no resolution. The problem is only on eCSFB devices they can't connect to LTE on hundreds of sites. They can connect to sites around metro Detroit. Older iPhones and stuff can connect to LTE fine. 

 

Problem is in cities like Whitmore Lake, Hartland, and a bunch other to name a few.

Any word on a second PCS LTE carrier, or 10x10? Sorry if that's a n00b question.

A second pcs carrier will be another 5x5. Refarming for the second carrier in most markets have begun a whole back. It shan't be too long before they can fire it up.

Thanks for the info! Is it due to the carriers being noncontiguous that they're not going for a single 10x10?

Early devices were only certified for 5x5 and Sprints spectrum is not always contigious with the PCS G block as most 30 mhz PCS A-F markets are of the A or B block.

I was scouting around the LTE Engineering screen of my wife's LG G4 looking for any signs of CA in Flint and Saginaw. I didn't see any CA going on but a new EARFCN caught my attention while in the heart of Flint on I-475. I verified on my LG G2 that the 2nd Band 25 LTE carrier was legit and not something I caught midscan.

As others mentioned, sectors 03/04/05 in your area are likely second carriers. SignalCheck will show a small "2" next to your provider name if you are on sector 04 or 05. Still working on getting 03 added; it conflicts with the way other areas of the country are configured. I hope to have that resolved soon.

I was finally able to screenshot the 2nd Band 25 LTE carrier that keeps popping up in the Novi, Wixom and New Hudson areas. It is a slightly different EARFCN than the 2nd carrier I found in Flint several weeks ago. (Screenshot is in the Network Vision/Spark EARFCN logging thread)

 

There is a 2nd Band 25 LTE carrier near DTW however I haven't been able to determine that EARFCN. The network at least in the Detroit area is heavily pushing my phone onto B41 even when B25 has much better signal. Same issue with another 2nd B25 LTE carrier out by the GM Milford Proving Grounds.

Another site in Farmington Hills just had 2nd B25 LTE carrier go online. Pulling 5-7 Mbps down on both carriers on a site without B41. Some much needed relief.

 

Also noticed spotty LTE coverage this morning through Highland, Milford, New Hudson with some sites entirely offline. I noticed something similar in Flint before I found the 2nd B25 carrier there so that leads me to wonder if some refarming is in progress.

Might explain my exact issues in the Columbus, OH market in the Granville/Newark/Heath areas.... Lots of lte drops and finding b41 2nd carriers and 10mhz b25 within the last few weeks!

Is Speedtest laggy?

 

Let's just say the speedtests on my G2 are faster than her G4 when she's pulling from 2 DL channels. Speedtest peaks very high and very briefly at the beginning then just craps out.

 

 

For some reason, yes. I've run into this problem on my G4. I've had to turn to Sensorly to get more accurate results, especially when CA is involved.

I'll have to try Sensorly. I haven't been a fan of the speed test aspect but I'll give it a shot.

I'm not the biggest fan of Sensorly's speed test function either. But when Ookla shows a test of 10 or 20Mbps, and Sensorly shows 100.... you know something is up.

I got a fluke of 236.78 Mbps down with 13.95 up yesterday with Ookla.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however. 
    • T-Mobile is selling the rest of the 3.45GHz spectrum to Columbia Capital.  
    • Still nothing for my AT&T and Visible phones.
