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 One® 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).

LTE Bands

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!

Do you have a model number or link to be sure of what variant we are talking about?
Based on the following webpage 3 uses Band 3 (1800 MHz) for LTE: http://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe
And based on the following, the US unlocked M8 does not support LTE band 3: https://support.t-mobile.com/message/358933
So based on this, the US unlocked M8 will not receive 4G LTE on your carrier.
Band support can be changed in software. However, it requires s-off ($25 US by sunshine). And unless you are getting a really good deal on the US unlocked version, I normally suggest getting the variant that supports your carrier's bands out of the box; to avoid the small chance you aren't successful in modding the phone.

This is the link to the one in question http://www.amazon.com/gp/aw/d/B00J3...htc+one+m8&dpPl=1&dpID=510p0WeVhaL&ref=plSrch
3U.K get 800mhz 1.8 and 2.6 but phone in question I can't seem to find out any info thanks.

LTE 800, 1800 and 2600 MHz correspond to Bands 20, 3, and 38 respectively. The specs in the page you linked indicate that it doesn't support any of those LTE bands (supports Bands 17/4/2/5). Those specs also matched the linked I provided in my last post for the US unlocked version.
LTE won't work for you unless you modify the phone's software/firmware as I indicated in my last post.

OK great thanks for the info and response.

[Q] Enable AWS connectivity in HTC M9

Hi all, I bought an HTC M9 from Asia and was very disappointed to learn that it does not work with Wind Mobile in Canada. Wind Mobile uses the AWS 1700 MHz band (same as T-mobile) which my phone does not carry. Will rooting enable the AWS band to allow me to use my phone with Wind?
Any advice would be greatly appreciated.

There are some variants of the HTC One M9 - do you know which one you have? For instance, is it branded to a particular carrier or is it a developer/unlocked version?
I don't know if bands can be unlocked, but we can at least help you find out what bands are supported by the variant you have.

Technically, I think (and someone with greater knowledge will have to confirm) a radio image from a variant that works with the 1700mhz band should do the trick. If, and only if, you variant support the band. Post all var info from download mode. Fastboot Getvar all while in download mode, iirc.
Kind Regards

If it's the developers version. They don't have 1700. Been like that since m8

This didn't work in M7, or M8.. Sorry really doubtful if it will work on M9

That's bad news..

Pardon my ignorance, but doesn't HTC explicitly mention the 1700 AWS band as supported on the developer/unlocked versions of the M9? Perhaps someone with more experience & expertise can confirm.

Hi,
Anybody has any updates or success regarding this? I am still having problems getting 1700 AWS working with my M9. (M9u international version) It will be great if someone could just let me know if they have done it previously (or not), so at least I know it is possible or if I should stop trying!
Thank you.

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
