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.

Which variant do you have? if it's the alita / explorer / transparent edition (8/256GB or 12/256GB) then there's NO BAND 20, which is LTE for many providers. Have you checked this?
EDIT: see here, perhaps you're in an area that doesn't use band 7 and only band 20? If this is the case... No ROM you flash can alter that, it's hardware related. ONLY global devices (64/128GB) support band 20

I have transparet ediotion 8/256gb. Checked there is no band 20 in my area but 4g works everywhere else

Do not relock bootloader after flashing rom, it will most likely brick your device. Flash another ROM if you like but you won't get band 20

May I ask, why do you want to relock bootloader after flashing a new ROM?

Guide how to unlock bands and 5G on 700mhz

Hello. 5G network is comming soon . I make today method for unlock 5G on 700mhz for this device . Problematic is only icon od network because 5G network is visible as 4G (have only 4G icon , but work in 5G mode , speedtest say the same) . Unlock method to avalaible soon , and publish in this thread . This method unlock all bands supported by device . Avalaible info about device is on frequencycheck.com with all bands . Unlocked all bands is visible on screenshot's in atach . What do you think about 5G on this device ???? Unlock 5G working only in european region devices and global . Devices from other regions have only unlocked new bands , I don't test this method on devices from other regions .
What you need to do that:
1.Any Qualcomm device - with this guide you unlock only Qualcomm cpu devices
2.NV values
3.QPST and QXDM for edit values
4.Installed lineageos with magisk
5.Network guru app for enable new bands after correct programing
6.ADB and FASTBOOT - with drivers to device too
7.Minimum 1 hour for do that
OK. Let's go:
Download drivers and flash lineageos with twrp - you need to install magisk and lineageos - Method for unlock don't work with stock miui .
Install drivers and turn on developer settings in your device and check 3 adb options for correct set all .
If you have magisk and lineagos , you can start adb and write command adb shell , in shell you need to write and press enter this command setprop sys.usb.config diag .
Start QPST and add port
Start QXDM , and find nv values (look down)
Change values and press write - do the same for second sim card (look up on qxdm and check dual sim , set this values for 0 and 1 if no possible you brick your device without option recovery signal. Write values to 0 and 1 after write press read and check . Do that with all values . Make copy of your values to notepad txt file for your safety . Reboot device , install network signal guru and lock all bands in 2G,3G,CDMA,4G . Device find 5G network on 700mhz as ''4G'' network because radio don't have icon and name for 5G .
More info and know how soon if i find some time for do that.
NV values:
0441: 0x780
0946: 0x0FF8
1877: 3460734838925428608
2954: 268894208
6828: 17591112253439
6829: 17591112253439
For enable total all bands in this device or other device with qualcomm cpu you must enter this values:
NV values:
0441: 0xFFFF
0946: 0xFFFF
1877: 18446744073709551615
2954: 4294967295
Values for LTE is not changed (LTE 6828 and 6829)
6828: 17591112253439
6829: 17591112253439
This values working on all rooted devices with qualcomm cpu inside with all wariants of cpu. If you want to share or publish this values write to me pm.
IMPORTANT: You must disable unused bands in EU if you are in EU in this app by uncheck in lock bands option CDMA frequencies . If you don't do that , your device to be scan all bands next five minutes than find signal !! If you are in other country , you can find in google frequencies used in your country and enable it only .
If you use my guide please press thanks

Tweaked system and unlocked radio give better speed of internet.

First try to use lineageos + network guru app and unlock all bands to values from second values and reboot . In guru app disable all cdma bands , activate all wcdma , gsm , lte and reboot . This possbile activate it automaticly , if not add comment .

Big thanks for that, I didn't know that is possible. Here in Germany we have Band 28 (700 MHz) for LTE (But also for 5G). Will it also be activated when I follow your instructions, or only for 5G? LTE B32 (1500 MHz) would be good too. Could you name the values for it? Or a guide on how to find them out?

Soo... Possbile you activate 2 bands 4G and 5G for 700mhz . You need only lineageos because i'm not sure how it working in stock rom . First published values unlock all bands of LTE and 5G too . For correct working please install network app guru , gapps
if you need , magisk for correct working of network guru app and lock bands all after unlock and reboot . If you after reboot lock in app all bands of lte you activate too 5G working . You can see in app band actually working , 700mhz working correct after unlock . I waiting for 700mhz in Poland because we don't have this band but i test in germany 700mhz (travel to germany in moment of tests 700mhz ) . Soon i Publish fixed lineageos for 5G and 4G network speed . My result of speed test in Poland after patch system and modem is actually : https://www.speedtest.net/my-result/a/6179268278 In Germany your speed test result can be faster than I have in Poland. You decide what you want to do with your device . 50% of unlocked bands for this device is here: https://www.frequencycheck.com/mode...al-dual-sim-td-lte-32gb-m1903c3eg-xiaomi-pine
