Any way to get to Field Test / RF Band Menu? (UPDATE! I Found Out!)

[AUG 12, 2012] Like the Title says. But I will like to strictly test the 1900 HSPA+ band only (auto off).
[Sept. 25, 2012] EDIT/UPDATE: Guess i'll explain in the OP how to get there (screenshots in 3rd post). My original/earlier post was for SELECT specific band selection. I didn't get that, but this is the best I could find. And this is SPECIFICALLY for TmoUSA user since we're in the middle of a refarmed 1900 band upgrade process.
Use service code in dialer: *#*#INFO#*#*. Select "Phone Information". Scroll down to make sure WCDMA (HSPA+) preferred is enabled. Then hit the menu button to reveal a few options. Hit "select radio band", and select "USA Band" which will use the 1900 band.
Now, it will take ~15+ seconds to switch. If it takes to long, turn off/on the radio below WCDMA (give the radio about 10 seconds per tap). If it shows EDGE, you don't have 1900 HSPA+ for your area/nearest tower, yet. If you do, then :good: :highfive: ! But TmoUSA JUST started rolling out 1900 HPSA+. So far, Las Vegas is the first city, with my city, Seattle, L.A., NYC, DC very near completed. You can try this site/map out to see where there has been reported TmoUSA 1900 HSPA+ sightings --> http://airportal.de

UPDATE:
If anyone here cares, I found out how to test the 1900MHz band on the GNex. I wanted to find out because Tmo is refarming their 1900MHz network. Plus Tmo just announced Las Vegas is the first to launch the full HSPA+ refarm with my city, Seattle, L.A., NY, DC, and other close to full launch. Tmo is downsizing their GSM to 10MHz or less (from atleast 20MHz), and bolting on their HSPA+ network on to it using atleast 20MHz on average on the 1900MHz band (some sites will only be 10MHz HSPA+ starting off).
I can't remember, but Tmo will also downsize HSPA+ on their current 1700 (AWS) band (from 20MHz to 10MHz) to make room for LTE over 1700MHz, or only use 5x5 LTE instead of 10x10 LTE. If that market has enough spectrum, then I'm sure Tmo won't downsize their HSPA+. But it varies from market to market (Tmo can have either high or mid spectrum), so let me wrap up how it will look with a good amount of Spectrum in a market:
1900 (PCS) band = 10MHz GSM / 20MHz HSPA+ = 30MHz
1700 (AWS) band = 10-20MHz HSPA+ / 10-2MHz LTE = 20-40MHz
So to wrap this up, I just wanted to use my GNex's 1900 HSPA+ band exclusively to see when my area (my local towers) in Seattle lights up, and I found out how (not pretty/not SPECIFIC bands).

Screenshots below... The "USA Band" doesn't use the 1700 band (Tmo) it seems. When I select it, I only get EDGE (1900) on Tmo, but I get a better signal (dB/asu) at work compared to using HSPA+ (1700).

What did you say? I missed it.

Just explain how please

You state you found out, yet did not state how.

Well did the "Auto Band" and the "USA Band"
The USA Band is good with signal strength, speed wise is slow ass ****.
The Auto band is still not bad with signal strength but not how USA band is.. Speed is there tho.

Did you even read my 2nd post? That's what were testing. If you have EDGE/slow speeds on the "USA Band", then Tmo hasn't refarmed your area/tower(s) yet. If you do get HSPA+ on the "USA Band", then that's great! Better HSPA+ signals in building for your area. I wish the GNex had DC-HSPA+ tho

You need an app. Theirs no native app or setting (maybe a service code?). I use Battery Monitor, but theirs a simple app to get into the Hidden Menu/Testing Menu. Use Test Menu (https://play.google.com/store/apps/details?id=appinventor.ai_Gareth_Hannaway_420.Test_Mode&hl=en) Then go to "Phone Information". Scroll down to make sure WCDMA (HSPA+) preferred is enabled. Then hit the menu button to reveal a few options. Hit "radio band", and select "USA Band" which will use the 1900 band.

Thx, that's the one.

I'll give a thanks for trying but you really didn't tell us something we don't already know.
Your op made it seem like you were able to go in and physically select radio bands (like from a list 850, 1700, 1900, etc). Not just select from us bands, aus band, etc. I guess when you posted that it "isn't pretty" we were expecting something different than what we already know.
It is already fairly common knowledge on how to access the service menu, so you don't need that app either.
Like I said, I'll give a thanks for trying, and you likely did help someone, so that's fine. But this topic has been discussed at length in the past.

Yea I know, its not what I wanted either (I wanted EXACT radio bands selections), but I found something useful for us TmoUSA users, which are in the process for refarmed 1900 by years end and beyond + LTE in 2013. I believe only Samsung's TW roms has that embedded to select specific bands. And do you have that specific thread you're talking about? I didn't see it in the search results.

You cannot choose the individual band. You can only choose US, AUS, etc. by pressing the menu button.

[Q] International / Unlocked HTC 8 (M8x) - LTE bands?? Majorly confused

Hi - I got a killer deal on an international (Asian model) HTC One M8x on eBay so I jumped on it... After receiving it, I noticed LTE is not working with T Mobile. The phone supports LTE 700 / 900 / 1800 / 2100 / 2600... Before purchasing, I didn't notice AWS/Band 4 wasn't listed. Oh well, still a great device.
I did some research and saw that T-Mo just bought Verizon's 700mhz; but 'Block A' only..? my phone supports 700mhz, but I'm not sure which block it will work with.
I live in a pretty populated area in Southern California, so I would assume that this area will be covered when T-Mo rolls out 700mhz on their network around early 2015.
Will my phone work on Block A? What is the difference between blocks? I just recently learned about the different frequencies, and now I'm hearing 'block A, B, C,' etc.. I'm officially confused.
Anyone with extended knowledge of LTE - your responses are greatly appreciated.
thanks!!!

According to the following Wiki, the 700 MHz bands used in North America are also called Bands 12, 13, and 17. These seem to correspond with the blocks you mentioned (A, B, C) with "700 a" (presumably Block A) corresponding to Band 12.
http://en.wikipedia.org/wiki/List_of_LTE_networks
Of the countries and carriers in Europe, Middle East, and Asia (the "international" M8 is actually called the EMEA version) only Taiwan seems to use 700 MHz, and its Band 28. So presumably, this is the band that is supported by your version.
Not sure, but you might be out of luck (your phone supports Band 28, but T-Mobile bought Band 12?).
It is confusing, I agree. My main takeaway is that there sure a lot of different bands that make up 700 MHz!

Thanks for the info and the link!! After reading the wiki page I did some more Googling.. It seems as though the 700mhz is available through bands 12, 13, 14, 44, 17 and 28. It's crazy that my phone only supports one of them. Too bad I won't have LTE....HSPA+ is horribly slow where I live. (unless it's about 3am, then I get a few MB up and down)
I noticed you have AT&T...are you aware if this phone will pick up LTE on an AT&T gophone? I will consider their $60/month prepaid if it will.
Or maybe another GSM carrier that my phone is compatible with? I would really hate to leave T-Mo but I miss LTE.
thanks again for your help!

T-mobile's AWS platform is mostly going to be a 1900 and 1700 setup if i remember correctly. they have purchased the 700mhz spectrum from verizon but no one is really using it yet. Only Verizon has even started to populate that spectrum with their new X-LTE which no one can really take advantage of. and really the HSDPA isnt that bad. i mean i have a tmobile M8 and i get LTE like 70% of the time but the rest of the time i'm on HSPAP and its fine i get like anywhere between 5-10mbps...
http://en.wikipedia.org/wiki/T-Mobile_US
you can look further down the page it shows you every band that they use or own.

Its not really that crazy. When they say "700 Mhz" I think what they really mean is that the actually frequencies used are somewhere around 700-799 MHz. And this can be divided up to many different distinct "bands". If you refer to the Wiki page I linked, you will see in the notes under the North America section, for example:
700 Block B
(↓) 734 – 740 MHz / (↑) 704 – 710 MHz
So the MHz number can be misleading; and its really the Band (12, 13, etc.) that you need to pay attention to. Or both the Band/block and MHz in conjunction really, as its often the MHz that is listed.

Don't think it work on AT&T's LTE network. AT&T uses Bands 4 and 17 for LTE. None of these are supported on the EMEA version based on what we've discussed.
Buying phones from 3rd party sources can be very tricky. US carriers in particular use very particular and often proprietary bands. This was true with 3G, and seems to be even more so with LTE. The bands used by even foreign markets has become increasingly less standardized with LTE (there was a good amount of standardization in foreign regions with 2G and 3G). One has to be very careful and resource thoroughly before buying a phone from any source aside from your carrier.

[Q] ZE551ML at&t APN settings

I am not getting 4G LTE. It is staying on H (hspa). I have the one plus one and get LTE.
The info online says this phone should have all of the bands required.
Any ideas.

Check Settings - Mobile Network settings - Preferred Network Type and set it to LTE if you have this option and is not already set.
But I doubt that this is your problem. You bought the Taiwanese phone, didn't you? While OnePlus supports all ATT LTE bands (17, 4, 2), the Taiwanese Zenfone 2 doesn't support band 17 (nor ww model), which is otherwise typical for less inhabited aeries in the USA, but it seems that is widely used by ATT. Try the phone in the downtown or another city and you'll probably catch the LTE on other frequencies.

Yes I purchased it from Taiwan but all of the sites show so many bands for this phone. Asus does a terrible job with their model numbers. There are so many different versions with the same model number. There is a 4 g setting not lte and that is selected. I did pick up 4g while driving through part of the city.
Is there going to be a US model?
Thank you

Yes. There is a US model and its supposed to be released in the next month or so. The link below, click on specs, shows the LTE bands for each region. Clearly shows the Taiwanese model not having the 17 band.

That stinks. I took that page as it will work in all of these markets. Oh well

There are some areas in the US that are only on LTE band 17. I suspect that's OP's issue.

The topic is about bands not frequencies. There is nothing such as 1700 LTE band. Actually both USA and TW phones work on approximate LTE 700 MHz but bands are different because uplink and downlink are different. So TW model works on band 28 and US one on 17.

I see now. Tnx for the quick response. Hopefully I'm not outta luck when the phone arrives tomorrow from TW. Do you think that flashing later on a radio or baseband will solve this issue?

It's not that simple. Luckily Intel chip supports all LTE bands. But they must be activated in kernel too. Maybe someone will find the method to activate the missed ones. Otherwise you are not so bad. With TW phone you are short of only one LTE band of four major in the USA, Europeans missed 2 of 3.

Frequency wise is matches everything AT&T needs, i just picked up my 4g/64gb TW model, i'll be playing with apn's to see if i can get lte to pop. Only getting H+ so far.
Correction, shipped with WW firmware, no 700mhz for us.

More - As posted above, this Taiwanese version is missing the LTE band 17. And there are some areas that this may be the only band available, so you will not have LTE in those situations.

Thanks so much.... I was having a heck of time here with my Zenfone 2 in Tucson AZ on T-mobile.... I was stuck on 2G... but updating the APN to fast.t-mobile.com and 2 reboots seems to have done the trick. So glad I don't have to EBAY this! THANKS AGAIN.... Loving this thing so far!

Well ****! This is where I am stuck win H+ on ATT.
No way around this huh unless someone does a new rom? Or is it hardwired?

How are you determining which band your on?
Not trying to be sarcastic, I am truly curious. I too am on Big Red, but couldn't tell you what band I'm on

@Badger50: Answer to your question is at https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery&hl=en_US
@BuffLG: Verizon's band 4 may be widespread but it is used to provide added capacity to the network. If the cellular traffic in your location isn't heavy enough, you may never see band 4 even though the P2XL supports it.

I use Signal check to see the bands. Or LTE Discovery.

Much obliged kind sir. I do know/remember that I'm usually on band 13, but was curious to know how to check it. Thanks again :good::good:

Lol with LTE Discovery it says I'm on ATT band 12, while signal check shows band 17.

Signal Check Pro easiest way.
Band 13 is Verizon's original LTE band has furthest range (700 mhz spectrum). Band 4 (1700 mhz) and 2 (1900 mhz) are their AWS spectrum.
Band 2 also has the highest capacity. Usually deployed in the most congested areas first.
Band 2 will technically be the fastest. Will probably be the hardest to connect to, but if you're close enough to a tower and getting Band 2 service, you're golden. I've seen speeds close to 100 MBPS on Band 2

I'd bet a nickel you're not seeing band 4 because of this bug: https://issuetracker.google.com/issues/37136986

This bug is relevant on Verizon, AT&T and T-Mobile but not Sprint (I believe) as they don't have Band 4 and/or 66. T-Mobile turned on MFBI at least several months (maybe a year?) before Verizon and AT&T did.
Again I don't know for sure if it's related to what you're seeing but it does "smell" that way. Band 4 in the Phoenix area almost always shows up as a Band 2 EARFCN that Verizon doesn't own when using Signal Check Pro as it is being reported incorrectly by Android. The EARFCN is correct under the same conditions using Network Signal Guru since it reads directly from the Qualcomm chip.

I always got band 4 until the last couple weeks .. I now get Band 3 instead of band 4 which seems to be faster if I get a strong enough signal.. Band 3 doesn't seem to be as strong a signal as Band 4 though.. Band 4 was always displaying as XLTE where Band 3 displays as LTE.. my old Moto Pure still gets Band 4 so I really don't understand why the Pixel no longer will get it! Got to be by design by Verizon, me thinks!!

That's the exact issue @turboencab is talking about. There is no Band 3 LTE in the USA. You are seeing Band 3 because of an Android OS/Qualcomm bug that cuts off EARFCN values above 65536. Band 4 can be "displayed" as Band 66 and most operators choose to do this now. Band 66 EARFCN values are above 65536.
Tldr; there is no Band 3 in the US. You are still connected to Band 4. Apps aren't able to display the correct band due to an OS bug.
Try to use CellMapper as a tool to see what you're connected to. The devs for that app can "correct" this issue based off some assumptions. https://play.google.com/store/apps/details?id=cellmapper.net.cellmapper

US carrier support

Hello, I'm looking at the Global version of the Redmi Note 5 (Basically the pro. Referred to as the AI Dual camera on GSM arena) and I'll be using it in the US on Mint Mobile. Mint is a T-Mobile MVNO and I'm not sure how LTE support will be on this. If anyone has any info on this that would be great. I believe Mint mainly uses B4 and B12 but I could be wrong. I've been looking around and found mixed responses of it having good carrier support stateside and others saying it won't work.

I can confirm that the phone will WORK on B4 (1700mHz/2100mHz) and B5 if you live in the greater Myrtle Beach area. (Acquired from SunCom back in the late 2000's). I don't know if your area has B5. On your existing phone, get LTE Discovery from the Play Store and sample your most common areas first to see what bands are most prominent. Being where I live, the phone mostly uses Band 5 over 4 because of the lower freq; able to reach tougher places where the higher freq B4 can't reach.

Thank you so much for the reply. I'll give that a download and travel around. Since posting I did discover my current phone supports the same bands. So I'm less worried. :good:

Lte works on band 4, but not band 12 on T-Mobile. But, for me band 4 is enough, if I don't get lte the device will switch to 2g. 3g straight up does not work for me on T-Mobile, although I've heard that T-Mobile does not use 3g anymore in the first place.
All in all, for me lte works just as well as my previous phone (zte zmax pro)

I can see that. When B4 and B5 don't work the phone just switches to 2G but without internet so basic voice and sms still works. about 70% of the time after it switches to 2G it'll tap onto HSPA+ (3.5G, coined 4G) and I got that for a while until LTE reconnects. Rinse and repeat until I have to leave to go somewhere.
