LTE Bands - One (M9) Q&A, Help & Troubleshooting

I'm interested in getting an M9, but concerned about LTE bands.
Basically, I travel back and forth between North America where I need Band 4, and Asia, where I need Band 1.
Sadly, I can't seem to find any model which has both Bands 1 and 4.
I'm wondering if anyone knows whether or not such a model exists, and if not, if anyone has tried adding LTE bands to the M9 yet, and whether or not they were successful.
Thanks!

LTE bands help.

I recently won a m8 in a contest. And through lots of searching I'm stuck, I live in the UK and my phone is from the US. I want to know if my phone has the right hardware to get lte on bands 3 and 7 as I'm on ee. But I cannot find out anywhere what hardware is inside the device, any suggestions? Thanks.
Check the preferred network (in settings) if you can enable lte connectivity.

LTE Bands
Hi!! a have the HTC OneĀ® Developer Edition (M8) and this supports the followings Bands in LTE: LTE Quad Band (Bands 17/4/2/5).
Check the exact model of your M8, with this tool: https://play.google.com/store/apps/details?id=org.tritonsoft.cidgetter&hl=es-419
Cid code is needed to find your exact model and get the description of networks supporting.

Any carrier branding (Verizon, Sprint, AT&T, T-Mobile) on the outside of the phone or on the OS (splash screen, etc.)? Mosts US M8s are branded, aside from Dev Edition, unlocked, or GPE.
As long as its a GSM M8 (Verizon and Sprint are CDMA/GSM) in theory you should be able to flash a different radio to get the proper band compatibility, even if your model doesn't officially support the needed LTE band (unlocking of bootloader and S-off required).

Unlocking LTE bands

Hello.
I'm wondering if anyone has had any success (or has even tried) unlocking LTE band 1 in a US model. I ordered an M9 but I am hoping to be able to unlock Band 1 to use it in Asia when I travel there.
I know there is a thread and people had some success adding bands to the M8, so just wondering if it'd work with the M9.

Thanks!
As far as I know, not possible on the M8 or M9. Where in that thread is the M8 referenced?
At the very least it was possible on the Verizon M8 for european bands:

Yes I believe that hack requires access to a menu found only on the CDMA menus.
I see. That's too bad. I wonder why they wouldn't just include Band 1 like so many other companies do.

Q on LTE Bands of VZW G4

Has anyone tested out an AT&T SIM card in a Verizon variant of the G4? I'd really like an android phone that has LTE bands for both AT&T/VZW to swap back and forth with my iPhone. The VZW Nexus 6 worked great, but it was just too clunky for me.
Thanks in advance for the help!
AT&T uses two main bands for LTE, bands 5 and 17. They also use bands 2/4/29/30 depending on the market.
The Verizon G4 supports these bands according to Verizon: 2/4/13, and these bands according to other research I found online: 2/4/5/7/13.
If that's true, it sounds like you should be able to get some LTE in most markets, but you would be limited as the only bands you could get LTE on would be 2/4/5.
Thanks for your help!

Do you know where 2/4/5/7/13 are confirmed online? I really wish LG would give us more lte bands like the S6 and iphone 6 do so that I can use it between the US and Europe.

I only saw it on some spec listings, I'm not sure where you can confirm it.

HTC M8 Dual SIM is it Possible to Change the Band to make 4G work in Switzerland?

How to know which LTE band?
Hi!
I know that this has been talked before, but I could not find anything that works.
I have bought a HTC M8 dual sim in switzerland. Back in Argentina, I tried to make 4G work, and, of course, it doesn't.
I have read that there is some chance to change the band, by the qualcomm.
so.. how do I know which band(S) does my phone have?
Thanks in advance!
I use "LTE Discovery" App. Available on the Play Store.

According to this webpage, it supports LTE bands 3, 7, 8 and 20. And according to list of LTE bands by country on Wiki, Argentina uses LTE band 4. So it makes sense that you don't have LTE.
While radios are typically interchangeable among "regular" GSM M8 versions (s-off required to flash radios); this is not true for the Dual SIM. So while you are correct that band support is software based on the Snapdragon 801, the normal method to change bands is to flash another carrier version's radio. I don't think you have another version's radio to flash. Some folks have modified the the NV values on the CDMA M8 to change band support. But to my knowledge, nobody has gotten this to work on non-CDMA versions of the M8 (the changes just revert themselves after reboot).
I suspect you are out of luck. This is really something you should have researched before buying the phone.

I kind of did. This is an fantastic mobile, besides the LTE detail; and by buying it in europe I've spent less than half of its price in Arg. pitifully.. I need the dual SIM. So, still a win win.
I will try to modify the NV values with QXDM... maybe i still have some luck left.
thanks =D

LTE Bands support - B8 (900) missing

hi guys,
I'm considering asking a colleague in the states to purchase and send me a Pixel XL.
I did a bands support check for my Taiwanese network and the Pixel supports 2 out of 3 of the used LTE bands on my network (Chungwa). The only one missing is B8 (900).
Anyone with knowledge of how LTE networks work care to enlighten me what the side-effect of this could be? Am I going to be having connectivity issues?
That'd depend entirely on how that particular carrier deploys its LTE. Some carriers use all their bands available, while others use some bands in one area and different bands in another.

Thanks for the info. Would there be any way for me to find this out?

I personally would install LTE Discovery and see what your current phone connects to in your area
That's odd. I thought band 8 is needed to get LTE with Chunghwa Telecom.
