Hello everyone! I'll start by saying I've done a lot of reading and searching, and I can't find my answers, so that's why I'm posting.
I recently acquired two LG v20s, which I intend to use as my primary daily handsets. The models are the h910 (att) and VS995 (verizon). Both have TWRP and magisk etc. I love the phones so far and everything is peachy, except one ... sordof big question/issue. LTE bands!! I've seen several people on XDA talk about the bands but I can't determine a clear answer. My first and primary question is, DOES the h910 support band 12/17?!?! Using network signal guru app, band 12 is listed. From what I understand (from what I have read) band 12 IS supported, and 17 is actually a thing of the past. If your phone has band 12, it can pick up all band 17 towers no problem, essentially meaning 12 has replaced 17. However, my h910 WILL NOT use band 12. Not if I force it, not on its own, nada. This is in places where I know band 12(17) exists, and is the strongest signal. In fact virtually everywhere, around the area I live (chattanooga TN). What actually really surprises me is that the phone gets great LTE reception everywhere I am 95% of the time, without band 12/17. I've checked numerous times (its kindof an ongoing thing...) and I've gotten every single other band, (2,4,5,30) usually with great reception and acceptable or good network speed. But never band 12. I can hold my galaxy note 4 right next to it, and the note will almost always be using band 17, and the LG refuses. Again , I can lock bands with Network signal guru, and still no bueno. If I lock the lg on only band 12, it will simply revert to HSPA.
Does anyone else have experience with this? Are other h910 users able to get band 12? Could I have a faulty handset? Is it software or hardware related? Just curious if anyone else has any info that could be helpful. I have noticed people in other random forums saying their v20 gets poor signal compared to other ATT devices, and I'm wondering if this is why (no band 12). Most people wouldn't know how to check what bands they're getting... or even know what "bands" are at all.
And a quick question about the vs995... I put an att sim in it, and got absolutely no signal at all on any band. Whats up with that?
Thanks in advance folks.
Seems US telecom companies are just weird I have 3 V20 phones that I use as 4G modem when in the country. My Vs995 worked for this for years but suddenly will not use mobile data here in Norway, tried factory reset. 1 910 that does not get phone signal at all - gave up on it, transferred screen and case to the VS995 which was worn, had broken screen. My Korean F800 with android 9 works fine. US carriers place artificial locks on bands it seems.

Hi all,
After sorting through xda for a few hours and pouring through the wiki entry and LTE references, I have come to the conclusion that I'm utterly confused about LTE compatability.
en.wikipedia.org/wiki/LG_G2#Network_compatibility
Is LTE compatibility so bad that you cannot easily move between countries and still get LTE coverage? Is it foreseeable that this will continue for a long time?
I'm living in NZ right now, and spend quite a bit of time in the United States, so I'm looking for the best LG G2 model to bridge the gap. Near as I can find, I think it will be the Canadian D803 since it covers LTE bands 4,7,and 17. NZ and Australia seem to be going for bands 7 and 8, and the US seems be in 4 (except sprint), and 2 and 17 (except verizon and sprint), with ATT alone on 5 and Verizon alone on 13. Al least according to the wiki for the G2 versions for the US linked above.
en.wikipedia.org/wiki/LTE_frequency_bands#Deployments_by_region
Is this data correct?
Am I also correct in reasoning that the D802 'global' version in supporting bands 1, 3, 7, 8, and 20, would not get and LTE support in the US? Has anyone tried this yet?
Thanks for the help and sorry if I missed an existing discussion on this.
Kia Ora mate.
The information i believe is correct regarding the D802. I pulled one from mobicity.co.nz. Was recently in the US with a Vodafone HTC One tri-band i purchased from clove.co.uk. (same freqs) With a T-Mobile prepaid simm i was not able to pull any LTE in San Francisco or Manhattan. That said the H band was plenty fast enough (compared to slow as sht NZ anyway) so i wasn't unhappy to not get LTE, but i understand, if you have it why not get it!
The LTE rubbish is reminding me of 3G/H issue where phones came in tri-band with 4 GSM bands to cover all. Its only since the Quad-bands have appeared that the 'portability' problem has gone, now with LTE its all back to sht again! to many bands. I notice one model at least (one from expansys.co.nz) of the Galaxy Note 3 has a massive list of LTE frequencies which of course is the only way phones going forward are going to meet international travellers expectations and capture sufficient LTE bands to be useful and portable. sigh. back to 'come on you plonkers sort it' level of deployment for our phones..
I'd personaly lean towards getting the more international (D802) model and take what you get from the provider of choice in the states. No way i'd want a verizon, at, or tmob purchased model; what with all the bollocks poor yanks have to put up with - stick to international versions.
thats my opinion anyway. good luck bro.

Various websites confirm its compatible with LTE band 17. My other phone connects to it while in my house, but the Zenfone will mostly connect to HSPA+, or sometimes LTE band 2. I cannot get it to stay connected to LTE unless I get into town or on the highway. (Actually as I'm typing, it switched to LTE band 2, but in awhile it will go back to HSPA)
If I root is there any way to unlock band 17? I'm in the US and my carrier runs off AT&T towers. I got this phone specifically because band 17 reaches far off places much better but I am unable to use it.
Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Hi!
Your correct model for band 17 should be Z012DC, the same used in Brazil.

For the time being yes you are. There is a way to unlock LTE bands on Qualcomm devices, but it seems ASUS has a fail safe built into kernel preventing it at the moment. If there is ever a custom rom developed for your phone then it maybe possible to unlock band 17. Until then no. I have been trying on my Zenfone 3 Ultra. Got as far as entering in the values for the bands I want and when I reboot it resets them to default. You can read up on it here:
https://forum.xda-developers.com/zenfone-3/help/help-putting-phone-usb-diag-mode-t3571627
Me and another user have been working on it. Maybe it might work for your phone. Always a chance.

Yeah I realize that now. Even though I'm stuck with my phone, I still can't find the z012dc for sale anywhere. Practically no seller online lists which variant it is. In fact, after a few hours of research, I never even knew there was specifically variants.

Whoa thanks man. I'll keep checking back and maybe I'll try it myself. Seems you guys are close.
I must say though, this isn't a complete deal breaker, though I am stuck with this phone anyway. The Hspa network is actually FASTER than LTE band 17 in my house. I'm just afraid if I travel somewhere and only band 17 is available I might run into some trouble. But then again, 3g or Hspa might still be able to connect.
Hey everyone,
I read for hours but unfortunately I haven't been able to find the solution.
So I bought a Galaxy S4 GT-I9515 in Europe and I'm not able to get any speeds higher than 2g on my USA 4g T-mobile plan.
The network mode is set on auto connect (LTE/WCDMA/GSM). I tried setting up a t-mobile 4g APN but it won't accept it (it pops back to standard after a few seconds..)
The simcard does work at 4g on another phone.
I rooted it with chainfire autoroot but this made no difference.
Anyone have a clue? At least 3g would be nice and should be possible..
Does the gt-9515 support the carrier's 3g and 4g frequencies?
Hey, thanks for thinking along..
According to frequencycheck.com, yes (both 3g and 4g).
Also, the t-mobile store didn't make notice of this being a problem. They were horribly incompetent though (just googling everything..) But you'd think they would at least check that much.
The I9515 won't get LTE in Europe as bands 2, 4, 12, and 17 aren't used there. The best you can do is HSPA (3.5G in the US) for data. If you're not getting at least HSPA the local carrier may have throttled you.

If I put the simcard in my old phone (moto G 1st gen) it makes an LTE connection so I'm not throttled.
I downloaded an app called LTE Discovery which doesn't read an LTE connection but says HSPA: -75.0 dBm is available.
With an internet speed test I'm only getting 770 Kbps however.
Oh, and I'm in Las Vegas currently (not in the middle of nowhere before anyone asks.. )
It's about the same speed in the Bay-area.
I misread your initial post. The fact you're not picking up LTE in Las Vegas means something else is wrong. In fact it makes me wonder if you even have an I9515. Kindly enter download mode and read off the model number please?
If things are as I suspect they are, then you're actually in possession of an I9505. My comments in my earlier post regarding LTE still apply, except it's the phone lacking the US bands instead of lacking European bands.

You're right, I mentioned the US T-mobile plan but forgot to clearly mention where the problem was occurring/where I want to use the phone (which I bought in the Netherlands). Just to be clear: I am in the USA and that's where I intend to use it.
ODIN MODE
Product Name: GT-I9515
Ok...I'm really confusing myself. For some odd reason I had the Straight Talk S4 in mind. LOL.
The I9505 and I9515 have the same bands: 1, 3, 5, 7, 8, and 20. You won't get LTE in the US on this device and are limited to HSPA here. Fortunately, HSPA is fast enough for multimedia, so unless T-Mobile is repurposing its 3G network for LTE you should see about 4 or 5Mb a second.
Thanks for analyzing, you seem to know a lot about this.
However, the primary problem is I'm not reaching any HSPA speeds either.
I know a lot about this, as I have an I9505 and live in the US.
The phone is working properly, so speed issues are carrier related. And it's not uncommon. I've had it happen myself, on AT&T towers.
Can anyone verify this actually works? Got this phone with the intention of having better coverage from band 12, but i've never seen lte discovery show anything but band 4.
I'm on the stock rom w/ magisk, anyone have advice?
Hi,
Can you help me to understand the difference between th band 12 and band 4? I am green to this.
Thanks advance!

In short, band 12 is a low frequency signal. The towers can broadcast huge coverage areas with the low frequency at the cost lower speed than their band 4 coverage areas. Band 12 for is great at penetrating buildings with thick walls.
Very few phones support this freq on T-mobile and I was hoping the mini could do it.

Are you testing it in the same place(s) you've had other phones show band 12 on LTE discovery? Officially it should work as of the Jan 2017 update. I'm pretty sure I have had it show band 12 when I was on stock (not rooted). I don't have a way to verify this now as my Mini is on LOS which currently does not support band 12 nor Wi-Fi calling. It's also my "secondary" phone until I get time to return it to stock (or LOS gets that functionality).

@googletermsofservice,
Thank you very much! Are there many service provider offer band 12 now? I mean, many providers such T-Mobile, ATT etc all offer band 12?

Does your phone stay on LTE when making a call (VOLTE)? If yes, the phone is working on band 12.
According to these website, the A7M should work with Band 12 and VOLTE & WFC:
https://www.androidpolice.com/2017/...ini-t-mobile-volte-december-security-patches/
http://www.spectrumgateway.com/compatible-phones
You need to make sure your phone is on at least the Dec update, if not newer.
Spectrum gateway is pretty reliable. I would use them as a first resource when considering a non-Tmo phone. I am supposed to receive this phone tomorrow. Will update if B12/VOLTE/WFC works...
I got the phone today. I can confirm that both VOLTE and WiFi calling work on TMobile after installing the update from the ZTE website here: https://www.zteusa.com/axon-7mini#support
Hey everyone,
First of all I want to say that I am not very experienced with flashing. I have done it 2-3 times before on my other 2 phones, so I will not undestand everything you say but I'll try to do.
Yesterday I got a Sprint Samsung Galaxy S5 from a friend. As far as I know it is unlocked so I decided to put another ROM that doesn't have that much bloatware. I first tried LineageOS (the latest nightly build for SM_G900P), flashed TWRP before that with Odin, but then I noticed that I cannot connect to my carrier, so then I decided to flash this ROM:
https://forum.xda-developers.com/sp...ment/rom-g900ppca-6-0-1-stock-rooted-t3387717
I flashed the ROM from the recovery, then I flashed the bootloader and modem with Odin. After that success! The rom fired up after 15 minutes of loading and there it was. I was connected to a carrier and had mobile data and I went to bed. So today I noticed that I couldn't get LTE everywhere I go and I started browsing the forums, but I couldn't find anything that could help. The only thing I found was this https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 , but all the download links were down.
So I decided to directly ask you guys and gals if you have a solution on how to get LTE signal on my phone.
Thank you in advance and sorry if I misspelled or said something incredibly stupid.
From what I know, the best connection you can get with an S5 in most countries in Europe is 3G. Sprint has the necessary band (2100 MHz) that connects to 3G in most countries in Europe. However, when it comes to LTE, the sprint S5 only has bands 25 (1900MHz), 26 (850MHz), and 41 (2500MHz). This is fine in the US for the Sprint Network, but European countries rely mainly on bands 3 (1800MHz), 7 (2600MHz), or 20 (800) for LTE, which are not found in the sprint variant.
I actually spent lots of time myself trying to unlock more bands using the link you posted, but I just couldn't do it. I couldn't access some menus that were necessary for the unlock during the process.
Also, from what I know, the carrier/data connection can only be acquired by using a stock rom such as the one you found. Custom roms like LineageOS will not connect to a carrier.
So every time i travel to Europe with my Sprint S5, i just put stock rom, and have to stick to 3G. So, that's the current situation with Sprint and LTE in Europe. I would be happy to hear any success stories.
I can confirm Band 3 1800 Mhz LTE works on Galaxy S5 900P Sprint on a network in Europe.
