I've been asking that question for months. As far as I'm aware, there shouldn't be anything preventing them from widening it to at least 60Mhz, as that is what Sprint had on air before the merger. It seems like they have the appropriate amount of spectrum here, so I don't know what the hold up is.

Ah. Same issue that SCP runs into when reporting the PLMN. That's unfortunate. Thanks for sharing the data you have though.

Ah, didn't know that. It's possible the site was broadcasting the keep PLMN, but it didn't show in SCP without the alternate ID setting turned on (under preferences and general).

Sorry... more questions. Was that via SCP or the engineering screen? Some phones don't report the keep PLMN without turning on the alternate PLMN setting inside of SCP or checking the engineering screen.

It's odd then that you were connecting to Sprint B41. It must be a keep site, and your signal must be weak enough on T-Mobile that your phone was finding the B41 preferable even though it was Sprint. Did you ever see any of the other Sprint bands or just B41? Hopefully it will be converted sooner rather than later so your experience can improve.

Cellmapper has a layer for the 312250 PLMN. Evidently it's been around for a while although I just realized it last week.

Sprint B41 and T-Mobile B41 are still operating in tandem here. T-Mobile has 40Mhz of n41 on air, plus 2x20Mhz of B41. Sprint still has 2x20Mhz of B41 on air as well. However, anywhere there is Sprint B41, there is generally also a T-Mobile signal so I haven't seen Sprint B41 except in rare cases for a long time. Couple questions for you... which device are you using, and what SIM configuration? I'm guessing you're still using a "Sprint" SIM (TNA)? That's what it sounds like. Was there no T-Mobile signal in the area you pick up Sprint B41? Usually if there is any T-Mobile signal, a TNA or TNX device will prefer that over Sprint. When you were connected to the Sprint B41, did you notice which PLMN was displayed, did it say Sprint Keep on SCP? I can't think of any reason for the network behavior that you described, particularly the weird PLMN. If they were converting the cell site to T-Mobile, the signal would go away completely. Sprint B41 won't magically become T-Mobile, they have to swap out the equipment.

With Sprint it's based off GCI patterns that were consistent among each equipment vendor, so every region followed the same rules (for the most part). Not sure we've seen as consistent GCI rules for other carriers.

Sprint SIM. Check our previous conversation. Not TNX.

Nope, you should be good to go! What country(ies) if you don't mind sharing?

If the T-Mobile SIM is in a different package, the SIM inside the phone will be a "Sprint" one and you shouldn't need to do anything except activate it. If the SIM From the S8 is the proper type, you might be able to use it. But there's a pretty good chance they've change which size SIM is used since that phone came out.

Did you order place the order through a Sprint portal or was it all through T-Mobile? The last upgrade I did a little over a month ago I did through Sprint (S21 Ultra). The order said it was coming with a T-Mobile SIM, but it was actually in a separate envelope and there was a Sprint SIM in the phone. When I made my trip to Iceland at the start of this month, that Sprint SIM still working for global roaming.

All AT&T along I-80 in Nebraska now instead of USCC or Viaero. No idea why when it would make sense to go with one of the actual roaming partners.

It's on our map.

They are deploying Nokia equipment in this market. The large antenna on the bottom is the one they are deploying in the Omaha metro for n71. It also broadcasts B2 and B66. It's also possible for it to be used for n25 and n66 when they start using that. Or they may put up separate antennas depending on the amount of traffic.

Haven't had to explain what CA is in a while. Carrier aggregation bonds two (or more) LTE channels together so they effectively act as one for downloading data. That's what I indicated when I wrote B2+B66+B71. All three channels bonded together. I don't think CA with B71 is that special, it doesn't act any different than any other LTE band. It is usable farther from the cell site (in good conditions) so that's a benefit to B71, but that doesn't help CA as the other bands need to be within range as we.

CA = Carrier aggregation. Not sure what you mean by the second half of your question.

Okay then you should have access to SA-NR, so you can ignore that previous post ha.

Connecting to an anchor LTE band will show the 5G icon on your phone. It sounds as though you were actually connected to 5G, though it may be slow due to the distance/signal strength.

NSA-NR doesn't report any data into SCP. You'd need to check the NR Engineering screen to see the NR PCI.

I have seen B2+B66+B71 CA, but so far no NR combos that include B71 or B41. I actually haven't seen any 5G in the last two days, not sure what's going on.

That must be new and/or not deployed yet here. B71 and B41 only show as LTE and don't allow for 5G connections.

If you are still using a "Sprint" SIM but have native T-Mobile (TNA) you won't be able to select 5G bands independently, an LTE anchor band will be required (NSA-NR, non-stand alone). B2 and B66 are typically used as the anchor bands.

Depends on if you are wanting to use T-Mobile or "Sprint" bands. B25 - PCS on Sprint. Most channels have been narrowed to 5Mhz. B26 - SMR on Sprint. 5Mhz channel. B2 - PCS on T-Mobile - channel widths vary from 5Mhz to 20Mhz. May have multiple channels. B4/66 - AWS on T-Mobile - channel widths vary from 5Mhz to 20Mhz. May have multiple channels. B12 - 700 on T-Mobile - usually a 5Mhz channel. Some areas may have 10Mhz. B71 - 600 on T-Mobile - Usually a 5Mhz channel. Some areas may have 10Mhz. B41 - this is a little tricky. T-Mobile has 2x20 channels on most sites with n41. But Sprint B41 is still on air as well. n71 - 5G on 600, channel width vary from 10 to 20Mhz. n41 - 5G on 2500, channel widths vary from 40 to 100Mhz. n66 - 5G on AWS, coming soon. A few select locations on air, but not sure on channel widths. n25 - 5G on PCS, coming soon. n260/261 - 5G on mmWave, very select deployment in a few large cities. Channel usually 100Mhz.

That I believe is ##DATA# if it works on a T-Mobile SIM. Not sure if there is an equivalent for T-Mobile.
