Use to calculate Qualcomm NV items for adding GSM / WCDMA / LTE bands.
Do you want to add any GSM / WCDMA / LTE bands to your phone? Then use this app to calculate all needed NV items.
This app is only useful for phone with a Qualcomm chipset.
If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread. That thread is for S5 model, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...
You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
>> NV items description:
- Adding GSM / WCDMA bands:
NV 01877 - RF Band Configuration
NV 00441 - Band Class Preference
NV 00946 - Expand Band Preference 16 to 32 Bits
NV 02954 - Bits 32 to 63 of Band Preference
- Adding LTE bands:
NV 06828 - LTE BC Configuration
NV 06829 - LTE BC Configuration DIV
DOWNLOAD: https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc
reserved
This app can show the calculation result in 3 formats: Decimal, Hexadecimal and Byte-swapped Hex.
Update v1.0.5:
- Fix UI issue on some devices.
- Add separate notation settings for GSM/WCDMA and LTE calculation. You should not change the default settings unless you know what you are doing.
I'm intersted in Qualcomm NV access, but not for cell band issues. There appear to be GPS issues with some Samsung phones, and there is some indication that those issues are related to a NV "privacy flag". Apparently older ROMs can turn this bit on and off, but newer ROMs don't - whatever value was left there is "stranded" there. There are people flashing back to CM10.x, setting this bit, then flashing back to CM11. I'm presuming that what is really happening is that they're tweaking this on NV location.
If we could simply read the NV location, we could compare its value to GPS functionality, and see if this is really the issue.
If the above is true, and if we could simply write this one NV location, we'd have a heck of a lot simpler GPS fix.
Thanks, vndnguyen, for your app. And it would be very nice if you add CDMA bands to your app. Thanks again.
if i am interested in enabling umts bands in somewhat old msm7227a based motorola, running gb 2.3.7, with no custom recovery, no custom roms or anything, but rooted.
should i even try?
thanks for making this, i wonder if my Snapdragon 600 on LG G Pro E988 can use this to enable China's TD WCDMA and TD LTE, since FDD is kinda different than TDD

Got a question. I found a discrepancy in your calculator.... Your NV calculator values do not match the NV value of the LTE bands my phone already has. So, how can I trust the calculator to give me correct values for additional bands I wish to enable?
It's at the bottom of this post, but I am putting a lot of information about my phone first, so you know the whole situation.
I have 5.2" 1440p, 3GB RAM Moto Maxx (XT1225), which has Snapdragon 805 -- same as the (Motorola) Nexus 6. In fact it was being tested by Google to be the Nexus 6 (or a Nexus 6 variant) as late as mid-August -- but Google decided to go with the larger size variant and only the larger size variant.
Motorola re-purposed this phone as the Verizon Droid Turbo (XT1254) in the USA and as the Moto Maxx (XT1225) now being sold in a handful of Latin America countries. We already have root, TWRP recovery.
When this phone was being tested by the FCC, it had these LTE bands:
But now being sold as the Moto Maxx (SAME FCC ID number), Motorola enabled more GSM bands and changed one of the LTE bands.
They disabled LTE band 5 (a minor AT&T LTE band), and enabled LTE band 3 (which is used more in Latin America countries).
QPST confirms the 2G/3G bands Motorola now claims for this phone:
Which means the LTE bands they now claim (2, 3, 4, 7, 17) are also probably correct.
Again this phone has the SAME FCC ID NUMBER. And as it's being sold in Puerto Rico (U.S. territory), that is very important. That means there's been no hardware change since U.S. FCC certification -- only software change.
Motorola also promises it has the SAME HARDWARE (including antenna) that the Droid Turbo (XT1254) has (even though the Droid Turbo has a different FCC ID number):
This is also important. It means really, Motorola could not sell the Moto Maxx (XT1225) in Puerto Rico (U.S. territory) under that FCC ID number if any radio-specific hardware had been changed at all.
Thus, we know the additional GSM bands, change in the LTE bands by Motorola was software modem change.
With me so far?
___________________________
Now the discrepancy...
In QXDM NV browser, in Line 6828, the XT1225 phone showed a value of 65630 (for LTE bands 2, 3, 4, 7, 17).
Yet, according to your app, with THESE LTE BANDS enabled (2,3,4,7,17)...
it should be THIS value: 65614.
Now I admit that's CLOSE, but it's not the same.
Therefore, how do I trust the calculator to let me enable MORE bands if this default number does not match in your calculator?
I have edited the values of that line to theoretically enable more LTE bands, but if the beginning number from the phone does not match what your calculator number says, then what exactly have I enabled?

Thank you for your patience for a such long post
But the problem was too simple.
Code:
If supporting LTE Bands are [COLOR="Blue"]2, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,626[/COLOR]
If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 7, 17[/COLOR]:

If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,630[/COLOR]
I don't how how many bands does your phone support. But if the value of NV 6828 in the QXDM NV browser is 65,630, that phone should support the following bands: 2, 3, 4, 5, 7, 17.
There is NO discrepancy here.

So, you are saying the phone supports LTE band 5 out of the box, even though Moto only lists 2,3,4,7,17 on the retail specs?
That after FCC testing they only enabled additional LTE Band 3, but did not disable LTE band 5?
If so, that's interesting.
Only to get you correct: this mod is only to extend the range of usable LTE/GSM bands for roaming, not to extend your connectivity while using your default provider in your home country (e.g. to get better coverage in areas where your default provider has a low signal strenght), right?

Or when changing from one carrier to another in the same country. Many carriers lock down bands the phone could receive, because they want the phone to only be used on their network.
Okay so I'm not really understanding the whole idea behind this. I have a Sony Xperia Z(C6603) and my phone already supports the LTE bands(LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20). My problem is that by default my phone and service provider should be able to have LTE working since my service provider also supports LTE band 4 and 7 on their network but upon choosing LTE network modes it has no reception at all, only 3G and HSPA. So I'm assuming I need to do additional unlocking here on my end for my phone but am not really sure why.
I'm able to access through the hidden menu of *#*#4636#*#* and change radio bands and network modes:
But I haven't changed the radio band and tested it yet because I don't know what the outcome will be and if there are any risks or hard bricking of it and don't know how to revert back to default. My service provider's network supports LTE band 4(2100MHz) and band 7(2600MHz). Would I need to go through QXDM to have these 2 frequencies enabled on my phone? Because I noticed how from the radio band list of my phone shows Euro Band which ends up to be 2600MHz but I'm not sure if that's how to enable LTE because it's Euro radio band. Am I okay as it is with my phone's default radio band and just unlock band 4 and 7 somehow through QXDM? Sorry I'm just really clueless and don't want to risk hard bricking my one and only phone.

Your provider supports LTE bands 4 and 7. Of those two, your phone can receive LTE band 7, but you don't see it. Are you sure LTE band 7 is in your area?
My carrier supports five different LTE bands (and my phone can receive them all), but in my area I only see two of those LTE bands. The others are not used in this area by my carrier (AT&T).

Yeah my carrier supports band 4 and 7 in my area, the towers are everywhere.
I checked it using this website: http://www.ertyu.org/steven_nikkel/cancellsites.html
both 2100/2600 are within all the cellular towers in my area.
edit: so if I'm able to choose LTE network mode on my phone, does that mean the LTE network mode consists of all these frequencies of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20? So everytime I change to LTE only or LTE/GSM etc etc, automatically my phone has 2100MHz and 2600MHz included? Which means I don't need QXDM to unlock anything further? It might just be a sim card defect or something maybe. Sorry I'm just trying to understand more
Hi
I am trying to use a US note 3 (n900a) on Europe, but I frequently lose connectivity (although bars are full). The only solution I found is to fix wcdma to 2100 freq, however this also means that I lose reception when there is only GSM coverage.
This app seems to be the ultimate solution for me to calculate a custom NV for GSM+wcdma2100. Am I right?
If so, may I use a NV writer without a box, by just using my usb cable?
Thanks a lot

Hi, in this app you can also find frequency bands

Good morning xda community,
I just purchased a brand new Z3 (D6603) in addition to my existing Z3C. Before I purchased the device I researched that it has the proper basebands for AT&T. Based on xda, Sony, and various other online sources, the D6603 should support the following bands:
LTE Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20; UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
When I received the phone, I immediately proceeded to root it and update it to 5.1.1. Once I did that, I proceeded to obtain a nano-sim to fit the device. Once I put the nano-sim in I got "no service" whatsoever. The phone doesn't want to connect to AT&T. To test whether or not the nano-sim is defective, I proceeded to take the nano-sim from my Z3C, which is known to be working. Again, "no service" on the Z3. Then I put the new nano-sim in my Z3C and it did work.
In addition, I rebooted the phone numerous times, toggled airplane mode multiple time and also went back to KitKat to ensure it is not a Lollipop issue. All of this did not help.
Following that I proceeded to check the service menu (*#*#7378423#*#*). The phone states it is a D6603 unit. So does the original Sony packaging. However, when I looked at the available (working) basebands in the service menu I couldn't believe what I was seeing:
GSM_850, GSM_900, GSM_1800, GSM_1900, UMTS_BC1, UMTS_BC5, UMTS_BC6, UMTS_BC19, LTE_BC1, LTE_BC3, LTE_BC19, LTE_BC1
Obviously several LTE basebands are missing when compared to the original specs - some of which I need to connect to AT&T LTE. That said, I also switched the band preference to GSM only and couldn't connect either. Again, the nano-sim is confirmed functioning.
Any idea what this is? Did Sony change the D6603 specs? Any chance I can get to the full baseband spectrum as per the original specs? Right not it is basically a $350 paperweight for me.
In case you suspect the firmware's I used to flash / root / update and subsequently downgrade, I used the following:
D6603_23.0.A.2.93 from here: http://forum.xda-developers.com/z3/general/guide-rootrecovery-how-to-root-install-t3017056
D6603_23.4.A.1.232_Customized_US_SuperSU_XZDR2.8.2 1 from here http://forum.xda-developers.com/z3/general/d6603-5-0-2-flashable-stock-23-1-0-690-t3056361
When flashing, I used FlashTool without any exclusions (meaning that I also flashed the baseband). Full data, Dalvik and Cache wipe was also always performed.
I searched via google as well as here on XDA, but I couldn't find any post which appears to have the same problem. Again, any help would be greatly appreciated. I just want the basebands that the phone was / is advertised with. Thanks in advance!
-Oban
Also, in the Info menu (*#*#4636#*#*), when selecting the band / region, I only get "Japan band" as a selection. This would further indicate that something is off here.
Again, any help is greatly appreciated!

Hi Oban,
Try turning off LTE and see if that helps.
There is some issue with AT&T's HD Voice which works on LTE causing issues
http://forum.xda-developers.com/att...ming-calls-lte-mode-m8-att-arhd-34-0-t3026710
Also, where do you see the list of bands in service menu. I couldn't find it
@aviralmsharma, thank you for your response. Turning LTE off doesn't do anything to change the situation. I tried LTE only, GSM only and every combo in between.
The list of available basebands is in the service menu *#*#7378423#*#* -> Service Info -> Configuration.
As for the "Japan band", that is in the info menu *#*#4636#*#* -> Phone Information -> upper right corner where the three "..." are -> Select radio band.

Lol, the ROM I'm using somehow managed to not show anything
Working Band/s: Unknown error

Attached is how it looks for me. Sorry for the bad quality, but i had to take a picture of the phone with my Z3C. And i am currently somewhere over the U.S. In an airplane, so upload is painfully slow.
Any idea how we can fix my D6603?

You're right, I do see more bands. Could that be because of the ROM you're running and/or radio?
Attached is screenshot from my phone. Installed a different ROM
.
Aviralmsharma, i honestly don't know. That isnwhy i posted the question here at xda to begin with.
As you can see from my original post, i used the firmwares that are commonly available here at xda and have been used by many people before. I even used the U.S. Generic firmware version when i updated to 5.1.1.
Obviously something isn't right with my D6603. What should I do? I fear flashing the baseband in FlashTool isn't going to fix it. Is there a way to flash or enable the radio so it reads the proper bands?
AT&T
Please make sure APN is Setup properly for your carrier

The APN setting are correct and set for AT&T. I compared it to my Z3C, which is also on AT&T, as well as to AT&T's APN information available through their website. I still believe the issue is related to the fact that my D6603 does not list LTE band 2, 4, 5, and 17 as working bands - all of which are AT&T's LTE bands.
Any other suggestions that might work?
More suggestions
There is another thread that I cannot find right now that details how to unlock bands on our phones. I believe it originated in the Samsung threads but I am often wrong
Found it
http://forum.xda-developers.com/member.php?u=4300205
@Oban I believe that you do not have a international D6603. You seem to have purchased one of the Japanese models hence the missing bands and the Japan radio band selection. I suggest you try to return the phone to the place of purchase.

Kansasboy, wow... so Sony created a sub-version of the D6603 (carrying no specifically different model number) which differs from the international (or what I would call standard) D6603 model?
Is this "Japanese model" the same, hardware-wise, as the international model? Meaning, are the basebands excluded because of hardware limitations, or is it the software? If it is the latter, can the software be modified (as suggested in other threads - enabling bands on Qualcomm radios)? Or is the only way to return it as per your original suggestion?

Based on the bands you have, your phone is the SO-01G model for docomo mobile in Japan that has been flashed with the D6603 firmware, hence the D6603 model. The S0-01G has 32gb of storage which you would find by flashing the S0-01G firmware. I can not guarantee you that the bands you are missing could be enabled. It depends if Sony simply disabled the bands in the modem or if the phone actually has a different radio filter than the D6603. I have successfully unlocked lte band 12 on my D6603 and will be more than happy to walk you through the steps in unlocking bands. However if I were you I would simply return the phone and get a real D6603

So... I did spend some time playing with the bands and working through the qualcomm band enabling thread on xda. I managed to enable everything needed and now the working bands read as follows:
GSM_850, GSM_900, GSM_1800, GSM_1900, UMTS_BC1, UMTS_BC2, UMTS_BC4, UMTS_BC5, UMTS_BC6, UMTS_BC8,, UMTS_BC19, LTE_BC1, LTE_BC2, LTE_BC3, LTE_BC4, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC13, LTE_BC17, LTE_BC20
I also went into the *#*#INFO#*#* menu and enabled "USA Band" (previously I only had the Japan Band option). I also toggled airplane mode multiple times and rebooted the device more than once.
Now the bad news: still no service. I recognizes the sim card, but it doesn't connect / register with the network. I also triple checked the APN setting.
Before flashing it again back to stock: any last suggestion / trick I should attempt?

For LTE the value was set as follows: 594143 / 10010001000011011111
Am I missing something?
And one more comment: I did all the above on the 23.0.A.2.93 Generic Canada firmware (I couldn't find a US Version, and I wanted to try something beside the Generic Global).
Would it be worth it to try all of the above modifications on the SO-01G-specific firmware?

Alright, despite the afford, the wife told me to stop tinker with it and send it back. It's now on the way back to Amazon. I hope i can find a true international D6603 that will work as advertised.
@kansasboy001, i do want to thank you for yoyr replies and help. I didn't even know there was a Japanese version of the phone. Appreciate it.
I am leaving the post paid cell service and going prepaid.
I since majority if prepaid US prepaid carriers are Sprint, T-Mobile and some AT&T. I want a GS 7 that will support all three carriers with as much bands possible.
Any suggestions for carrier versions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
There's only 1 model variant in the US now - they all have the same band support - it all depends on firmware as to what bands are active.
But one thing to consider is that while a Verizon/Sprint phone may work on Tmobile/AT&T the same might not be the case the other way around because the AT&T/Tmo phone will probably have the bands disabled in the FW
Just to show this is my tmobile S7, wcdma bands that are enabled - so seems it would support Verizon/Sprint on bands 800/850/1900/2100 -- 2100 is a band not listed on Phonescoop FYI

Guess we'll have to wait until a Sprint/Verizon person gets their phones and get into the service menu to see what it looks like
Wasn't sure if they were the same thing (left Sprint well over a decade ago for GSM and never looked back lol)
But based on your info, then my first comment is probably true - Tmo/AT&T variants will not work on Sprint/Verizon due to not having the proper FW

Is there a way to set preferred lte band like the s6?

I haven't tried yet. Don't want to mess something up
nest75068 said:
There's only 1 model variant in the US now - they all have the same band support - it all depends on firmware as to what bands are active.
But one thing to consider is that while a Verizon/Sprint phone may work on Tmobile/AT&T the same might not be the case the other way around because the AT&T/Tmo phone will probably have the bands disabled in the FW

Is this right? The FCC filing shows 5 models (SM-G930V [Verizon], SM-G930P [Sprint], SM-G930R4, SM-G930A [ATT], SM-G930T [T-Mobile]). It shows each version having support for different bands.
How would one go about changing the firmware? For instance, if I have the VZW version (doesn't support LTE Band 12) and want to use it on T-Mobile, how would I change the firmware to T-Mobile's?

As for FW change, not sure how that would go. We shall see what happens when the Dev's get their hands on these and start to figure it out.

Has that been ever done successfully on any of the carrier devices? You couldn't do that on the S6 to enable certain bands. I'm not too familiar with the other devices.

Well looking at Phonescoop, the S6 had separate CDMA and GSM models. Based on my understanding of the S7, there is 1 phone for the US market (where each carrier has their own model #) but internally the phone is the same.
The only other phone I can think of that had 1 variant for the US market was the iPhone (where each phone internally was the same and the bands that were active was dependent on the FW)

I think on the S5 you could change some of the NV to enable different bands. The iPhones are all one variant and they don't disable certain bands either. I have a 6S+ on T-Mobile (supports all bands); if I swap the sim for Verizon, it'll work on all of Verizon's lte bands as well. The S7 for verizon shows support for bands 2/4/5/13 so I'm not sure if I were to place a T-Mobile sim that it'll enable band 12 since it's not enabled on Verizon's version.
I guess we'll have to wait and see if it's truly one variant of the S7 in the US.
I'm in the UK, I'm wanting the S7 Edge - but don't want the 8890. The screengrab shows it supporting the main UK bands too.. Hm! Can you get simfree phones in US?

Figured out on the Tmobile variant how to set preferred band.
For me Band 12 is great for calls/texts in my building but HORRIBLE for data so I always switch to Band 4 as my only lte band (which means I don't get calls since I have VoLTE off but no biggie).
To do this on the S7 requires a few more steps than the S6, you have to
*#2263# for service menu
Select clear all bands
Then select LTE band preferences and choose the band you want
Then hit the more button(top right hand corner) and select back
Then hit Apply band band configuration
To revert back to normal go back into the service menu and choose select all bands and then choose apply band configuration

I just want band 4 to be the preferred one instead of b12

Well another thing you can do is go in and specifically turn band 12 off only and will still net you calls and whatnot

We normally can purchase phones outright but they are usually branded by their carrier. AFAIK, there wont be a unbranded version in the US. However, isnt the S7 doing something with the phone locking to the first sim/carrier being placed in the phone?
i have a g930t that is working with a Verizon sim card in it . and this is what i did
1: i used the sim unlock app on the s7 tmobile to unlock my phone
2: then flash g930u firmeware
3: i dont know if this one helped or not but i did *#2263# to slect all the bands.
4: turned off the phone
5ut the verizon sim card and turned it on
6: after it finished booting up the phone you will see a message on the screen that will say something like" need to reboot to configurate your sim card" hit ok and let it reboot.
enjoy
Can one use a G930P (Sprint S7) on T-Mobile USA with full band usage? I am assuming the phone would need to have a custom ROM on it.
I am traving to Cancun Mexico on the 23 of june. I currently have an AT&T SIM inserted into my SIM Unlocked S8+. I know AT&T has service in Mexico, but as far as I know the best they got is 3G. I was wondering if I was to go outside out of their AT&T coverage and into another companies coverage while in Mexico Whether it be CDMA or GSM. Would the phone work on all their network bands, or would it be only GSM bands because of the AT&T SIM inserted? Another option I thought about was getting a different SIM in mexico. That might be a better option just in case roaming on my phone is not possible with other carriers out there that aren't GSM supported.
Any help will be greatly appreciated. Really hope someone has the answer to my question, because google sure didn't lol.
Hi
If you have an AT&T Sim and your plan has international calls, text and data you don't have to worry, is like you're in home.
I went to Vegas a few months ago and had no problems, the only problem is that if you want to make calls to local numbers you have to dial the country code before the phone number. (Don't worry when you Google any phone they give you the whole number with the country code)
Also in Mexico there's only GSM Networks, we use to have CDMA but is now discountinued and is only for military use, as for the coverage you don't have to worry unless you get far away from the city maybe if you go to the pyramids you'll get reception but I don't know I don't use to go to Cancun.
Plus, I don't know how Americans think in Mexico we don't have LTE?? Yes we have LTE and in lots of places and it has the same average speed that in USA, you'll get like 15 Mbps in busy hours and like 30+ or 40+ at night, I'll attach you a screenshot from my speed test. (I live in a small city it's probably you'll get better speed in Cancun)

Thanks for all your helpful information. You cleared up a lot of information that I needed to be answered lol. Although I have one more question.If I have a AT&T SIM inserted will my unlocked phone work on other Bands not supported by AT&T in Mexico, or am I stuck with the the Bands AT&T supports?
The 3G service of AT&T in USA is 850 band. In Mexico all carriers uses the same band for 3G (H+)
For LTE, mexican carrier Telcel uses AWS Band (1700-2100) and, as far as i know, AT&T Mexico uses the same band for LTE service.

Why your S8 does have the LTE icon and mine doesn't have it ?
I'm on Telcel and when I'm put the same Sim card on my Lumia 950XL there shows the LTE indicator without an issue. But my S8 doesn't show the LTE indicator. Always says 4G.
AT&T Mexico uses the same bands that AT&T USA so it won't be a problem as long you're using an AT&T Sim.

That's because the Root files in your phone every carrier put some custom files in their phones, I use to change the icons in my S6 by editing the CSC file, also other people change the build.prop file to make the phone think is from another carrier and country.
Of course you need Root if you want to change the icons.

Nope, my Galaxy is from AT&T I haven't checked the CSC but I think I'll be IUS (from Iusacell) ir maybe other code for AT&T Mexico, still I haven't rooted my phone to check it.
You can flash a CSC from an American carrier if you want the LTE icon, personally I don't like the LTE icon in my phone shows 3g (H) 4g (H+) and 4g LTE (for LTE... XD), I just prefer the 4g icon for LTE.

Nice. Thank you very much.
Does anyone know the band spec of S536DL? Is it same as Tmobile side? or is it Same as Verizon?
Anyone able to flash this one to either stock firmware? tks
I'd like to know the same thing so I know what cellular radio bands it has. I just got the A53 5G on Straight Talk, & and it's the same specs as the unlocked version: 128GB of storage & 6GB of RAM - not the 4GB which it is listed as having - and was my main concern. It could Be the "V" version since Straight Talk/Tracfone/Total Wireless all use Verizon Towers. But the "U" version would also work well with Verizon bands. The "V" version has mmWave and my thinking is the Tracfone Samsung A53 S536DL would have that clearly marked in the advertising as a marketing ploy if that was the case... so my 50% guess is it's the same as the "U". But then again it uses Verizon towers, so maybe "V"? I don't know of an app that will scan the phone and tell me what radio bands it has.
I entered service mode by dialing *#0011# in the phone dialer and seeing as I was connected to LTE band 13, so I've come to the conclusion it's definitely the "V" variant since the "U" doesn't support band 13. I don't think you can flash it because as far as I know the boot loader is locked. But if you SIM unlock it, you'll get all the same compatible LTE T-Mobile bands that the "U" has (2,4,12,66). For 5G you'll get Band n260 (39 GHz) & Band n261 (28 GHz). So it will totally be usable on T-Mobile. You'd only be missing out on one 5G band (Band n41 (2.5 GHz). I don't now what carrier you have but mine is a Straugh Talk Pre-paid and I'm going to unlock it after 60 days and use it with Mint Mobile which uses the T-Mobile network.

How did that turn out? I am thinking of doing the same thing. HSN A53 Tracfone deal, then unlock to mint after the bundled plan is used up.
