The only real feedback I can offer is that the System ID or SID is not what I would expect to see for 1x800, but then again, Alcatel might have their SIDs assigned differently than Samsung markets like mine. I think all the Ohio markets, Pittsburgh and West PA all use a 5 digit SID that starts with 22 for 1x800. The PCS SIDs here are 4 digits and begin with 4 like what is displayed in your screenshot. My market primarily uses SID 4396 for 1x1900.

The thing is, on the iPhone, 1x800, or Band Class 10, comes up as "Secondary 800 MHz band[10]" whereas his screenshots say 800 MHz cellular band, which on the iPhone comes up as band class 0, and is used by Verizon and many other carriers, but AFAIK, not Sprint. The Field Test screen seems like it may be bugged and is displaying older info/mixed info, which wouldn't surprise me considering how buggy it is.

According to my logs the sid 4162 for sprint can be found in Northeast PA east through North New Jersey and into Connecticut. 1x800 in that area uses a SID of 22422. 

 

 

I would like to know what the channel number means

Each band is broken down into different channels. The channel number is used to find the center frequency.

Yeah this info came from an iPhone 6s I don't know why it's not displaying the proper info but I did read on the article that was posted in the comment below very helpful

iPhone 6S field test is extremely unreliable. My phone ALWAYS displays Band 0 in 1x despite the correct band being displayed in the 1xEV-DO section. This does not appear to be a problem that Apple will address. Best thing to do is go off of the SID.

Yea...in my findings, field test for 3G/1x only works once per boot so after you've opened it once and it populates, you have to reboot your phone if you want to open it up again. 1x band class usually never loads, EVDO works some of the time. Honestly if you can get SID to load it's petty much always correct so that's your best bet.

I did reboot the phone but it was my brothers phone so I didn't have much time to tinker with it

      I think the push for them is adding US Mobile as a MVNO with a priority data plan.  Ultimately, making people more aware of priority would allow them (and other carriers) to differentiate themselves from MVNOs like Consumer Cellular that advertise the same coverage. n77 has dramatically reduced the need for priority service at Verizon where the mere functioning of your phone was in jeopardy a couple of years ago if you had a low priority plan like Red Pocket. Only have heard of problems with T-Mobile in parts of Los Angeles. AT&T fell in between. All had issues at large concerts and festivals, or sporting events if your carrier has no on-site rights. Edit: Dishes native 5g network has different issues: not enough sites, limited bandwidth. Higher priority would help a few. Truth is they can push phones to AT&T or T-Mobile.

      Tracfone AT&T sims went from QCI 8 to 9 as well a couple years ago. I'm pretty neutral towards AT&T's turbo feature here, the only bad taste left was for those who had unadvertised QCI 7 a couple months ago moved down to 8. In my eyes it would have been a lot better for AT&T to include turbo in those Premium/Elite plans for free to keep them at QCI 7, while also introducing this turbo add on option for any other plans or devices. As it stands now only a handful of plans can add it, and only if you're using a device on a random list of devices AT&T considers to be 5G smartphones.

      My Red Pocket AT&T GSMA account was dropped to QCI 9 about a year ago.  Most recently 8 for the last few years prior.  Voice remains at 5.

      https://arstechnica.com/tech-policy/2024/05/att-announces-7-monthly-add-on-fee-for-turbo-5g-speeds/ Hopefully we don't ever see T-Mobile do something like this. Based on how I was treated with my Credit Limit, it's definitely not the same company it was before the merger, and it's entirely possible they'd try it.
