You can check the bands and frequencies for SPRINT here:
http://www.gsmarena.com/htc_one_(m8)_cdma-6233.php
For the sim unlock it is up to "firewater" compatibility, since you need to S-OFF your device first.
Regarding compatibility with firewater, your question should be: How can I make sure that my device will be supported by firewater?
The answer: You cant! Its just a matter of luck for the moment.
There are alot of people who successfully S-OFF their devices with firewater, and there are also unlucky persons like me, who cant (i got 2 devices that i cannot S-OFF).
There is also a bounty thread for people which cannot S-OFF:
http://forum.xda-developers.com/showthread.php?t=2733870
If SIM unlocking is your concern, I suggest you to buy it unlocked (yeah i know the price is higher).
For the time being there is no provider offering SIM Unlock for Sprint. Believe me, since I have a SPRINT standard M8 device which i cant SIM unlock for the moment.

Thank you for the information..I'm an htc lover...i can buy it factory unlocked in about the same price...but i want that version...i really liked the color combination and what h/k addition offers...i know that i can port the h/k software to another m8 but i like the whole package...it's unique....i live in Greece....bought my friend some months ago an already sim unlocked sprint htc one m7 and it's working fine..So to sum up..if i got it...it's not 100% that i would be able to sim unlock it..... Also i saw on the gsmarena on the lte frequencies sprint version support LTE 800 / 1900 / 2600 my carrier lte frequencies are 1800 MHz, 2600 MHz...... so i should be able to have lte at 2600MHz?

Im not quite sure if the LTE will work flawlessly since usually the antenna is optimized for the specific carrier. Sorry i am not sure about it...

How about reboot phone don't touch anything in mobile network options and go directly to phone info with the 4 digit code *#*#4636#*#* go phone information and change the preferred network type just don't touch anything in the mobile network settings and see if that works.
I had done this on Verizon GPE ROM and got data working by only switching in phone information once I toggled in actual mobile settings I was screwed maybe that will work for you

What should i select there?

You should select what ever network type you need in order for your data to work. But if you touch any of the settings in mobile network it just stops working completely. Well at least that's what happened to me but you could also try manipulating the band's that are supported in your location

please help me.

No lte please help!

Hi, Im from Mexico and my note 3 uses a 4glte sim card for Telcel company with my plan, its suposed to work the att version here (1700MHz and 2100MHz) but my smartphone only shows "4g" (+HSPA) even in the areas with lte's support. I even tried many things on the hidden menu *#*#4636#*#* but nothing works even if I choose the lte option.
My note 3 info:
SM-N900A
Android 4.4.2
N900AUCUCN2
Custom rom dynamic kat 6.1
Please help me! Greetings from Mexico!

Don't gona appears "LTE" if your custom ROM use "4G". But no worries 4G/LTE are same thing. You can install this MOD for Xposed anyway and try. Good luck :highfive:

Thanks my friend but I´ve made many tests and I only get +hspa speed, never LTE, I dont what to do

I think you just need to add telcel APN in Settings/Connections/More Networks/Mobile Networks/Access Point Names
Nombre: telcel
APN: internet.itelcel.com
Found here https://www.youtube.com/watch?v=I-N-atXwP_w hopefully that works for you and you won't have to reflash!

In my case it also shows G but i get the speed of hspap as here I have no 4g. G means gsm here. Either u get 4g/lte or G/gsm. I have checked it in about phone > network> cellular type. However my internet connection is pretty stable in my stock marshmallow rom and i am not rooted.

Did u touch or change anything in hboot? Or changed your kernel or radio version? Or the problem started from the begining?
---------- Post added at 11:59 AM ---------- Previous post was at 11:54 AM ----------
One more thing. As you said you are using it in Indonesia so u should check if the 3g bands of your carrier matches that of your phone. Most of the 3g bands of sprint m8 which is made for using in USA doesnt match carriers in Asia

If your friend is not having any issue and you are having one then i think you should take it to the shop from where you bought it. And as far as i know the sprint varient always have a network issue. I have seen many others posting the same thing. Btw you said u have s on and locked bootloader. So how did u get it to use other carriers than that of sprint? In my case i have super cid and s off and there is a long method to unlock the carrier. And i dont have any network issues. How did u manage to use other sim cards?

Then i guess ur neighbour messed up something while unlocking. Coz the ways i know to unlock requires either $25 by sunshine or free by firewater but for firewater method u need to be rooted i guess. And also the firewater method is not reliable. In any case the bootloader should have been unlocked. Did u ask ur neighbour about this problem?

LTE Band Question

Hi everyone,
My carrier band is supported on the Mix namely B3 and B7. However, it is not possible to get 4G signal at all on the phone, only 3G.
Any suggestions?
Thanks

Thanks for the suggestions but I have tried that to no avail. I install the LTE discovery app and there is no LTE signal at all.
I also tried flashing the modem file from China dev rom but it is also the same.

So your old phone worked ok? Can you try a different carrier SIM card to check.

What carrier are you on and what are your APN settings?

I'm in Singapore and my carrier is Starhub. The apn settings are auto created and I double checked against other phone it is the same settings.

There is an issue with the latest update that causes the device not to connect to LTE. According to the official forum, it should be fixed in the next update, which is about a week away.
Edit: Some have suggested reflashing your ROM and doing a factory reset as well. Most of what I have seen points to the developer ROM. If you are using the developer ROM, then flashing back to the Chinese Stable and factory resetting the device should solve it. If you are using a vendor ROM, the same is recommended.

Just an update to anyone facing the same issue. This is a bug on the development rom and hence it affects all eu / custom rom that derive from there. Once flash onto the latest stable will resolve this issue.
