Yes, in the Harrisburg PA area, I have trouble with outgoing voice on some phone calls because the upload speed is so bad. Web pages can take forever to load as well. Usually, I just give up and use my Verizon phone. Supposed to get the low frequencies on a Sprint tower near me in about a year. Currently said Sprint tower stomps on the very usable T-Mobile 5G stand alone NR signal. They just don't have the system set up properly yet.

My girlfriend's S21, does that, my S21 Ultra , does it and my Note 20 Ultra 5G does it. I'm thinking it's more of the T-Mobile system rether than all of these phones. Sure would be nice to hear from owners of Motorola and LG devices to see if they get the infamous "No Connection" and band jumping that so many of us with Samsung devices are experiencing. All the phones that I mentioned above are factory unlocked non-carrier versions. Actually, I just remembered, I have a T-Mobile LG V20, which of course is not 5G, but when I put my T-Mobile SIM in it, the V20 jumped bands and also got the "No Connection" message. It's got to be growing pains of the T-Mobile system causing these sorts of issues. Hopefully in a year or so things will start to settle down as T-Mobile takes over the Sprint sites and converts them. T-Mobile tends to work rather rapidly on these sorts of things...

Yes, this is to be expected. I was speaking to the engineer that runs all the T-Mobile cell towers in most of my State (PA). He's got quite a big territory. The engineer tweaked the towers around my house, so I would have minimal problems in the meantime. I'm very please with the attention that I was given by T-Mobile. You definitely would not get that from AT&T or Verizon!

Yeah, it's all messed up. I came home from grocery shopping this morning. I was still in the car in my driveway and called the neighbor across the street. I picked up an item for them. The entire trip home I was streaming Spotify. No issues there. The phone call was all garbled to the point I had to hang up and call back on my Verizon phone. It turns out when I checked the band with Signal Check Pro afterwards, that I was on HSPA. After an airplane mode cycle, I latched onto 5G N71. What the heck wax the deal with connecting to HSPA? I was using my Note 20 Ultra 5G phone. This same thing has happened to my girlfriend with her S21 5G. Very frustrating.

I know the site near me in Harrisburg PA is supposed to get all the low frequency bands where the existing Sprint gear is now. I'm crossing my fingers!

I'm hoping that they just don't have the logic programmed into the base stations yet. I have the same situation in the Harrisburg PA area. I can hold onto a -123 dBm signal on band 25 or band 2 when a nice -98 dBm signal is available on band 71 or n71. Makes absolutely no sense. I do have the momentary "No Signal" lapse between locking onto the next band though. That appears to be more widespread than I thought...

That same behavior happens around the Harrisburg PA area as well. The phone (Note 20 Ultra 5G) bounces between bands with moments of "no connection). I've noticed that other people's T-Mobile phones exhibit the same behavior. It's not only just my phone. The strange thing is that when Signal Check Pro shows "no connection" during a VoLTE phone call, the call is not interuped, nor does it drop. Hopefully in the next year or so as the Sprint sites are converted over to T-Mobile, the system will be tweaked to have the phone park on a band with a good signal and stay there instead of the band hopping that currently persists.

Very interesting! Thanks.

When the Sprint sites are shut down, will the frequencies be reused as T-Mobile frequencies? 1900 MHz, 850 MHz & 2500 MHz? I've heard that the Sprint site near me will be broadcasting low frequencies and 5G next year.

According to the engineer that I was dealing with, Shentel is still running the site. He had to go through legal channels to get the Shentel personnel to make the changes that he wanted. He said it'll be about another year before T-Mobile will have control of the site. In the meantime any changes still have to go through Shentel.

I am very impressed with the T-Mobile engineering team. It was rough for them because Shetel still owns the tower that was causing all my signal problems, but they adjusted the band 41 cut off point so that when it reaches -113 dBm, the phone will search for T-Mobile band 71. I am so impressed with the attention they gave to me as a T-Mobile customer. You definitely would not get this type of help and concern from AT&T or Verizon. T-Mobile actually cared about my reception and customer experience! I'll be a T-Mobile customer for life!

I'm not in the best signal area. Since T-Mobile has built up the network, I do get a much better signal at my house though. I'm hoping to get a Femtocell. That would solve most of my issues. The problem is they do not, at this point, have the newly lit up Sprint signals set up properly and they stomp on the perfectly good T-Mobile signals.

I can actually get stand alone 5G NR inside my house now that I excluded the Sprint bands. The system is not set up properly. With the Sprint bands active they stomp on top of the native T-Mobile bands. I've been going round and round with them for weeks on this. I don't see a need for the Sprint bands, even as fill in, as there is excellent native T-Mobile coverage.

With the Samsung Band Select app in the same exact location, this is what I can get in my house.

Latches on to Sprint and only sees Sprint as neighbor cells. Completely ignores all the available good signal from T-Mo.
