How to find current Mhz band connection

I've looked EVERYWHERE and I can not find a screen, app, or menu that will tell me what frequency band I am connected to (800, 1900, etc). I like to force my phone to roam and I'm curious what frequency band I get, as well as knowing if/when I get Sprint SMR 800 1xRTT/LTE. 

 

When I had the hybrid iDen/PCS Motorola ic502 It would tell me right in the network menu. But this was a good 5 years ago and I haven't been able to find a phone that does this since.

I downloaded signalcheck pro and a handful of other signal apps and I still can't find this. I'm also running CyanogenMod 10.1 and I can't figure out how to get into my engineering screen to find it via the dial pad (or any other of those screens for that matter). 

 

Any insight or help would be awesome!  :D

Lose the alternative ROM, stick to a stock ROM, and you will get your engineering screens back.

SignalCheck will display 1X800 instead of 1XRTT if you are connected to an 800 MHz signal.  So, if you see 1XRTT assume you're connected to 1900. 

 

I believe also the band number is an indicator you can see on the engineering screens but I don't know which bands correspond to 800 off the top of my head.  I could be wrong though.

 

Stick with SignalCheck Pro, and I believe it has a feature that it will notify you if you connect to 800.

Hi Kyle, no need to go back to a stock ROM. You need the Sprint Diagnostics app, available from xda-developers here. The app requires root. The engineering screens are available on the Debug menu. There's a whole lot more, too.

 

 

Have fun!

*UPDATE*  I forgot to mention that you have to flash this from recovery, since it's a system app. The OP's link is dead, but you can download it from farther down in the message thread.

Band 10 - 800mhz SMR

Band 25 - Sprint LTE G-Block

Band 1 - PCS block (I believe)

 

Are we talking 3GPP, 3GPP2, or both?  One uses bands, the other, band classes.

Ah yes, my post is ambiguous, trying to just answer the question for the OP in a simplified way.

Another FYI: 

 

*#*#33284#*#* will get you to the Debug screen. The code is 777468. From their you can get to the engineering screens.

Depending on your device, you may have trouble updating your PRL to one that will allow you to connect to the 800 MHz bands if you're not running a stock based ROM. I don't think it's possible to update a PRL from CM 10.1 on a Sprint GS3. If I'm not mistaken, one must backup your current setup, flash a stock ROM, do your PRL & profile updates, and then restore your nandroid backup. I don't think you can get the right PRL if you sit on a CM based ROM all the time ... at least not with a GS3. Not sure about other devices.

I'm not sure that's still a problem for CM10.1 - I have Profile and PRL updates in my Settings (GNex, not GS3). But in any case, there are many ways to update the PRL on an AOSP ROM. Sprint Diagnostics, from my message that you quoted, will do the job nicely. And it will even write a custom PRL if that's what you'd like to do.

 

Have a great evening!

I'll give that a try on my GS3 next time I venture over to AOSP land. Thanks for the tip.

If you're already rooted, give it a try. It has a lot of features - access to the engineering screens, data & APNs, re-provision, LTE logs, etc. It's a very useful tool.

So for a Sprint Note 2, this app will update PRL, while on CM10.1?

Hi Jef,

 

I can't answer specifically for the GNote2, since I don't own one. Here are the screenshots from my GNex:

This only works on the gnex because the android base is designed to work with those functions. The cm maintainer for the note 2 has been trying for weeks to get those functions working in the note 2. If your base build doesn't include the functionality, then the app won't work, it is just calling those functions...

For Settings, yes. But what about the write PRL functionality? Flash it and give it a try. You won't know until you do.

 

Have a great day,

Earlier today I was trying to figure this out from my iPhone... Where would I find this on the Field Test screen?

iOS Engineering screen is accessed by dialing *3001#12345#* then call. If you're connected to LTE select the Serving Cell Info and the band will be listed (PCS is band 25, SMR is the elusive 26 and the 5s isn't capable of band 41). If you're not in an area with LTE you'll have an option for 1x and EVDO. The band won't be listed on 1x (it used to on the 4s, but for some reason it's excluded on the 5, 5c, & 5s). EVDO will show frequency and band.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      As far as I know it's ubiquitous. Ultimately the network decides if you should use VoNR vs VoLTE but pretty much anytime my phone is in standalone mode and I place a call, it goes over NR.   Yup, it was terrible. After a while, I just connected to the WiFi, and that worked fine at about 90Mbps. I get the feeling that rather than doing a "real" upgrade where they install new antennas, upgrade backhaul, etc., T-Mobile instead installed new radios onto the existing and already overloaded DAS and called it a day, which isn't enough. Compared to Yankee Stadium, where they actually went and deployed new antennas/radios for their n41 upgrade, and you're able to get upwards of 200Mbps at sold-out games, Arthur Ashe really is a joke. What's worse is that the folks in their NOC likely know this already, but no effort is being made to change that. I'm not asking for T-Mobile to deploy mmWave everywhere like Verizon but there is a real use case for it at stadiums.

      Does anyone know how well implemented is VoNR in the 5 boroughs. Does anyone use it? I have an iPhone 15 Pro. Does anyone know if T-Mobile is still working on upgrading their network? It seems like the service has gone down. My phone struggles in parts of the Belt Pkwy, and data is slow.

      I come to the US Open men’s semifinals and finals every year, and I’ve never been able to use my T-Mobile phone successfully. Usually AT&T is the top performer—good to hear Verizon has upped their game.

      One sector down, two more to go — — — — —  I was at Arthur Ashe Stadium for the U.S. Open today and the good news is that there is an n25/41 DAS setup throughout USTA Billie Jean King National Tennis Center. From the "boardwalk" to the outdoor concession area, to inside the stadium; you connect to standalone n41 and n25 everywhere via oDAS and iDAS. The bad news is that in the actual stadium it's beyond useless. While I saw strong coverage as indicated by signal bars and I was able to make calls and send texts, there was no data throughput at all. Running a speed test failed 9 out of 10 times. The only time I got a speed test to work was by switching to LTE funnily enough or by using NSA 5G where the test would initiate via LTE and then n41 would kick in giving me ~20Mbps. T-Mobile has so much traffic on their 5G network that now n41 gets bogged down before LTE. That was a first for me! In the stadium in the same area Verizon got 1.2Gbps on mmWave and LTE kept timing out when trying to test it. My Boost line on AT&T got upwards of 150Mbps on C-band and I know they have mmWave deployed as I saw their Nokia mmWave antennas deployed but I was unable to test it. In the outdoor concession area T-Mobile performed well getting over 150Mbps on n41. AT&T in these areas saw over 250Mbps on C-band and I didn't get the opportunity to test Verizon there. It just seems like 140MHz n41 is not enough capacity for the amount of people inside the stadium. Hopefully T-Mobile is considering deploying n258 to all of these stadiums since they now own that mmWave nationwide. It'd make a world of difference in terms of capacity at these venues.
