No, im from Chile and bought a VZW one m8 from ebay, here we use lte band 7. As advice if this NV value dont work try to get 6828 and 6829 NV value from a TMO One M8.

Same here. I use it in Bulgaria and LTE is very limited, also AFAIK LTE shortens the battery life..
If you don't have coverage and you have LTE it will keep scanning -> battery drain

Its very possible in fact I got the NV value from a Europe htc one m7.

what should i do for European people who have 3g/h neywork?
pls help me =)

This works in Europe too

Working in Uk?
The strangest thing... I enabled said bands while I was visiting Pakistan and it IMMEDIATELY worked (provider there uses band 3, 1800 MHz) It worked just fine in Dubai as well, also on band 3 and on my EE sim on roaming on etisalat. But then I get back to Uk and still no LTE. Just HSPA!
I am on EE network which I am sure uses band 3 as well. I know there is an LTE signal in my area because when I pop my sim in my wife's iPhone 5 (not 5s) it picks LTE immediately (which I believe is only capable of band 3 in UK)
Also, I am not getting LTE on my Verizon anywhere at all.
So I know band 3 was unlocked because it worked great in Pakistan and Dubai but its not working here. Anyone have any ideas why this is?
@BobbySteel: does yours work in Uk?

So if I am American, do I even need or want to try this?

If you're on Verizon; no.

What about me ? I have AT&T and current use only HSPA+
do you have an idea if this band that you unlocked is also available on ATT?
Great job

What are the default LTE bands the verizon m8 comes with?
Also is it possible to unlock AWS HSPA+ bands?

I have the exact same problem. I can't get any UK sim cards to reliably work in the UK but it works well in every other EU country I'm in. I've tried both Voda and O2 UK. Strangely though there are a few locations (near Victoria for example) where 4g *does* work. But it's geographically small and other areas my old sgs4 got 4g don't work on this handset w the same sim. Bizarre.

I was hoping this would be a more popular thread but guess the phone is getting old now...

AFAIK, HTC One M8 has LTE bands 4/13 unlocked. And it´s global on 3G.
Edit: Bands 4/13 only(NV 6828 = 4104, same NV 6829)

TMO uses LTE bands 2-4-12 in the continental US and Verizon 4-13. Therefore you should unlock bands 2-12 to use both carriers.
So, NV6828 and NV6829 original values(4104) must be replaced with 6154. Hope this helps.

Both Vodafone and O2 use LTE band 20 in the UK, are you sure that band is enabled?

Using: http://www.worldtimezone.com/gsm.html http://en.wikipedia.org/wiki/Nexus_5 and http://en.wikipedia.org/wiki/UMTS_frequency_bands Italy 3g is all 2100 MHz which is band 1. So either you have a radio that's less band 1 friendly for 3g.
Recommendations: 1) Try a different modem: http://en.wikipedia.org/wiki/UMTS_frequency_bands
2) It may be bad hardware. You could take the phone apart and try to fix it or RMA it if it still has a warranty.
3) Live with it.

Not sure if international unlock is different but ##72786# in dialer will reset data provisioning to factory without needing msl and only resetting data configuration without resetting phone or user files. The 3282 one will allow u to view data settings without msl but msl needed to change anything, some custom roms/kernels have this bypassed allowing data settings accessible without msl. Id try scrtn first (72786)
---------- Post added at 01:16 AM ---------- Previous post was at 01:13 AM ----------
Or signal guard app may be worth trying if rooted as it will have an option for radio locking where you can change preferred network type. The app also can be used unrooted just not sure what that is like as I havent tried unrooted.

Is there any option to learn msl in my phone ?

You'll have to contact sprint, if you call care they will sometimes give it to you, or if you know someone at a store they might be able to look it up for you

If you want to root or are rooted there are other options as well, but without the trouble of that it should be easier to get it from sprint. They do have terms for it which can be found somewhere on their site, I'd google sprint unlock policy. You will most likely come across workarounds as well from the same search results.

If u r rooted or would rather not gamble your luck with the various different service reps (all working for the same company) http://idoneapps.com would be, in my opinion, the most simple and surebet option available to obtaining the msl, among several other options that I believe would be a tremendous help to you. There may be other methods out there, however, just from my experience with the same model phone and whether marshmallow or lollipop it has without a doubt worked successfully.

And apologies if the link is not within the rules as for being free or whatever, I just wasnt sure how to go about it as it had once been posted on a forum on here being shared for free and was requested by idoneapps to be removed so in respect to that I only felt comfortable pointing in the honest direction, what you decide from there is entirely up to you.

S6 unlocked from US Cellular- NO 4g LTE on new CMDA carrier

Purchased my phones from US Cellular unlocked. Recently left US Cellular to prepaid company ROK Moble also a cmda carrier The thing is 4G LTE seems to be blocked on all my phones! I was going to root and install a custom ROM because I was convinced that its a US Cellular final FU but "ping pong root" dosent yet support US cellular phones and I don't want to trip KNOX.
Any help would be appreciated.

i suggest you look at ROK LTE bands, they may not be compatible with your phone.

Above tips are all valid. Also make sure you have a ROK mobile APN selected. And if not present, create it according to thier guidelines.

Rooting for US cellular S6, SM-G920R4, should be done through CF-auto-root. Download the root file and the appropriate custom recovery, example: TWRP for sm-g920r4. Flash cf root first and then custom recovery in that order via Odin. You will be rooted and ready to install custom ROM s.

Forgive the newby question but I thought you dont use APN's in CMDA mode?
in any case I can't view or change the APN settings

I hope you all understand that I greatly appreciate your help and taking the time to answer.

According to Wikipedia, ROK uses Verizon's network. The same Wikipedia article states ROK/Verizon uses LTE bands 2, 4, 13. This site and this site state the US Cellular 920R4 uses LTE bands 2, 4, 5, 12, 25. So your phone only works with 2 of Verizon's LTE bands. Maybe your area uses the LTE band you're missing (13). Verizon is notorious for screwing people, so Verizon might be limiting or excluding LTE access to MVNO operators like ROK.

First thank you for the reply. US Cellular's LTE network is on bands 5, and 12. is it possible for the us cellular software to limit network selection to one of these 2 bands even though the phone made to receive LTE data from all the all of the above bands? because as I look at it rok supports band 12 but not band 5 (in terms of those bands on par with US Cellular) but rok also supports band 2 and 4 which apparently my phone is capable of receiving data on but for some reason unable to....

unlocked on tmobile?

Anyone know for sure if the n41 5g mid band will work on tmo? I know the phone has n41 and is available but would it require tmo firmware?
I have always purchased unlocked and used without problem on tmo...

I just got the phone yesterday, and I'm having no problems with their 5g.
