How to find current Mhz band connection


Recommended Posts

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.

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.

    • While I've been loath to update my Samsung devices past the May 2022 update to keep the Band Selection tool, I note that it looks like Android 14 is going to add Timing Advance for NR to the API.  (Was looking today as I have another Verizon A42 5G now that I'm going to unlock for T-Mobile, and wanted to figure out if I should let it update or not.)  Since I can technically make band changes from *#73#, on the A42 5Gs, I can probably live without the Band Selection tool if a later Android version adds something useful like TA values. I assume SCP will be updated to support that once it becomes publicly available.  The real question is whether or not the phones will support it.  My S21FE and A42 5G devices do on LTE, but I know the S22 and the A32 5G do not support it even on LTE, providing just zero in that field. - Trip
    • The A23 5G appears to support all of the Dish NR bands except n26 which they don't even own yet, and n29 which as SDL can't be logged as far as I can tell.  https://www.phonescoop.com/phones/phone.php?p=6760  I mean, n71, n66, and n70 are there, and those are the ones I'm most concerned about. I know that's not trade press, but I've found Phone Scoop to tend to be missing bands rather than including bands that should be there. I don't really care if it's carrier locked; if I'm buying a device specifically for Dish, then I'm probably not switching it out in the immediate future. - Trip
    • I mapped out the various phone choices to Dish's NR bands.  Used trade press for many of the phones, which can be unreliable.  Just starting with N71, you are down to three phones: Moto G Stylus 5G 2022, Moto Edge+ (2022), Celero 5G+.  Add in the less frequent n66 and you are down to: Moto G Stylus 5G 2022, Moto Edge+ (2022).  The Moto G Stylus 5G 2022 then walks away with the rest of the bands.   A negative is even if you pay cash, the phone is carrier locked for a year.

    • After nearly a month T-Mobile seems to be finally expanding n25 beyond the initial 5 sites they were using. However, it seems to be quite the mess. The three sites near me are all using different size channels. I'm getting a 5Mhz channel that's only using the G Block, a 15Mhz channel that's using the C Block, and a 20Mhz channel that's using C+G, each from a different site all next to each other. Very confusing.
