[Q] No data roaming option - Sprint HTC One (M8)

Hi,
I bought a gsm unlocked sprint htc m8 from a 3rd party vendor recently. (It was only after the purchase that i realised it was a sprint phone). The phone worked pretty well on my network until i moved to a different city. The trouble is that data doesn't work here for some reason and there is no data roaming option on the device.
The vendor has agreed to sort it out but it will be quite a while before I go back and give him the device. So i wish to try something on my own.
My research on here has yielded that I probably need to change a few settings in the default.xml under system/customize/ACC. Or there could a better way of enabling it.
So far, all the steps I need to take seem disjointed and therefore I'd like someone to please guide me through a step by step process on how to enable the data roaming option. I'm sure I'd be able to follow the instructions as I've previously installed a custom rom on my HTC One S.
The phone is not rooted, although it says "tampered" when i enter the hboot menu. In the same menu it also says "unlocked"
Let me know if you want any further information

for Sprint users, the roaming appears after being activated/provisioned...you can try changing "sku_id" to 42 in system/customize/ACC/default.xml (it's near the bottom)....but u will need root to change that file. If you have TWRP recovery, it should prompt u (when rebooting to OS) to install root if it's not detected

Thanks!!! Much appreciated. So once i'm rooted, do I need some tool to pull the file off the phone or can i simply edit it on the device itself?
Yes I have TWRP, will it auto-root my device when i get the root prompt?
Also I read somewhere, under the default.xml these entries need to be changed to "true" or will changing the sku_id suffice?
<app name="Android_Ril">
<item type="boolean" name="allow_national_roaming">true</item>
<app name="Phone">
<item type="boolean" name="supportNationalRoaming">true</item>

The alternate method is for those who have the roaming options but are greyed out. In my case there is no option roaming option at all, may be because the phone is unactivated. Anyway I'll try the previous steps over the weekend and post results

Hey, so I installed Viper m8 rom, data now works in roaming but it catches only EDGE. 3g is not working. Any clues on how to make that work?

Hi,
I bought a GSM HTC One M8 from a third party vendor in India.
I don't get data roaming options in my phone. I have flashed it using Bad_Boyz_Sprint_ONE_M8_Harman_v1.5
Changed SKU_ID to 42. Updated data and voice roaming guards to Allowed as well. Still no success.
Can anyone help me out?
Please let me know if more information is required.
Thanks

This did it for me

You need to be S-off
Try the following on you responsibility
- You should know your SPC, you can read it with CDMA Workshop or CDMA DFS Tool.
- Install QSPT (http://forum.xda-developers.com/show....php?t=2263391)
- enable diag mode ##3424#
- open QPST configuration, from port tab add your device diagnostics port.
- from start clients tab choose service programming then ok & click on read from phone.
- on system tab choose automatic for roam preferences.
- on UMTS System tab choose any for pref service domain & any band (last bottom right) for proffered band.
- click write to phone, then your device should work on GSM mode with modified HTCOMADM_SPCS.apk.

i have a att sim, flashed it and still does the same as before flashing. says dial 611 or go to myatt.com to activate hotspot?
Not working for ST AT&T sim, wireless or tethered. 1.08 odexed.
I can't speak to JMZ's flash, but I can guarantee the manual method works (& worked for him, also). Give it a try.

I just did a manual merge of the telephony.db in the zip, rebooted, and it's good.

Well. It seems I have hotspot enabled on my plan but not getting charged for it. That's why this mod works for me but jot anyone else.
So the Att version is broken

Don't know. Typing this now on my A500 using First hotspot with Straight Talk/ATT SIM.
Flashed the zip and it didn't work for StraightTalk. Not familiar with the installer but seems to be a script bug when checking for ATT / ST selection.
Manually copied the ST db and it didn't work, got the error "dial 611 or go to myatt.com to activate hotspot"
And it changed my ST APN settings.
I manually updated the db with SQLlite and got it to work with StraightTalk.
The ST db file in the zip uses the old APN setings, I was provisioned with the new settings.
See this thread for details on the ST APN settings.

So… what's the procedure?
Analyzing your files in SQLite I see you changed tables 2 and 12, but I can't seem to figure out the logic behind it. My experiments don't get me too far.

No, nothing in build.prop. What ROM are you running? What SIM are you trying to use? I was using AT&T via ST, is your T-Mobile via ST?
If ST, was there a recent change in the APN settings? I have read that there were some updated AT&T ST APN settings, but they do not work as well as the old ones, at least in some markets. I tried them to see if there was an improvement and actually lost all data, so reverted.
Stock 1.08.
I'm outside the US at the moment, so my carrier couldn't be further from AT&T, T-Mobile or any of their MVNO's. But the APN settings are correct: tethering works with factory unlocked phones.

You need to be rooted and s-off for changes to stick in system files. Good luck.
Ran into a tethering issue after addition of a third, but not selected APN. Tethering showed connected but there was no Internet connection. I tried setting up the new ST settings to see if my SIM could access LTE. It could not. I then simply re-selected my original APN. All seemed to work OK, except the tethered wifi device could not see the internet. The additional setting changed the order in the telephony DB list. Went back to just the two APNs and all is again fine.
I cannot get telephony.db to stick on my friend's First for some reason. No hash match after reboot every time. Tried zip installer and ADB push, in TWRP and in OS. 1.08...1 S-off and rooted. Also tried deleting telephony.db-journal first like the installer script does. So strange because I've done it with my phone. Note that I had downgraded from 1.08...4 to do this.
Is JmzJBSenseMyst_v3 new? That's what im running. I tried this on MEDUSA as well with no go.
It basically messes the phone up completely un-useable since I'm on Straight talk att blue sim and on apn - tfdata.
So how do you get tethering on this phone with apn - tfdata for att straight talk blue sim for 4g lte... ?
I can't get MMS to work at all... it won't download says download error even after putting the mms proxy and port 80 etc..

[HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk

[HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk
Streamlined Guide for Domestic T-Mobile GSM Unlock for SPH-L720
Credit for all of this goes to @autoprime and @nicotheandroidguy
A few notes: I used Windows 7 for the odin flashes , my phone is a SPH-L720 and it is not active on the Sprint network, also the sim card from t-mobile was inactive (brand new from t-mobile store.) and it has a bad esn. I am located in the Phoenix az market so I'm able to take advantage of the 1900mhz band that tmobile has here.
I'm unsure of how this will work with mnvos or other primary carriers and frankly I don't care at the moment, this is my primary phone. Update: confirmed hspa+ for tmobile, metroPCS, straight talk and AT&T.
I HAD MY NEW UNACTIVATED TMOBILE SIM CARD IN THIS ENTIRE TIME
1) First I reverted my rom to a stock MF9 rooted touchwiz rom, instructions and one click odin here:http://forum.xda-developers.com/showthread.php?t=2486134 I’m trying not to straight copy and paste someone else’s work so take a look at that post if you need a clean start. If you are coming from non stock you will need to boot into stock recovery and wipe data/cache before you get started. (I also later used SAC’s rom after a failed attempt at an AOKP fix and it worked as well ) you can switch to any ROM later and the unlock will stick.
2)I rebooted the phone and followed the instructions listed here in post #1 http://forum.xda-developers.com/showthread.php?t=2415587
3) I went to the dialer and typed *#0011# which brought me to the "service mode" Menu.
IF YOU HAVE TROUBLE GETTING THE HIDDEN MENU TO OPEN DO NOT FEAR! I had a ton of trouble at first. In some builds you need to activate an option by adding a line to your build.prop or changing the no flag in efs/hiddenmenu to ON. Google it, there is a ton of help out there.
4) Press the left menu softbutton (the menu button that lights up and vibrates when you touch it) then press the either the button “select” or “Key Input” and type the number 1 or 2 into the box, if nothing happens press menu and select the “back “ button then repeat. This app is sort of like a tin can radio, you can kind of tell that it’s working, but it doesn’t work well.
Depending on if you pressed 1 or 2 in the dialogue box it will take you into either an UMTS or CDMA menu. If you are in the umts menu, press the menu button and select back, this should then proceed to the next step.
5) Select CDMA, then 1.COMMON, press next page twice until you reach page three of COMMON and select 8.PREF MODE SET and select GSM_WCDMA_ONLY
6) Press menu and back until you are at the main menu and select [1]UMTS, then select [1]DEBUG SCREEN, then select [6]PHONE CONTROL, select [2]FAKE SECURITY CONTROL and make sure it is set to ON
7)Press menu and back and select [3] NAS CONTROL. We are going to check a few different settings in this menu so remember how to get here cause I don’t want to repeat myself.
[1] CIPHERING CONTROL = OFF
[2] INTEGRITY CONTROL =ON
[3] SIM CLASS CONTROL = UMTS
[4] REVISION CONTROL = DO NOT TOUCH
[5] RRC(HSPA) CONTROL = DO NOT TOUCH
[6] DUALMODE IMPROVEMENT CONTROL= DO NOT TOUCH
[7] NAS AVOID SECURITY CONTROL= OFF, 0
[8] BIP BLOCK = 1
8) Press menu and back twice, you should be on the PHONE CONTROL menu. Select [7] NETWORK CONTROL, select [1] GFC and make sure that it is set to [1]GSM/(E)GPRS/WCDMA REL8 .
9) Press menu and back and select [2] BAND SELECTION and select WCDMA/GSM ALL for both WCDMA and GSM band preferences. I selected the ALL choice for LTE as well even though I know it isn’t supported for TMOBILE.
10) Under the NETWORK CONTROL menu we just came from select [4] AQUISITION ORDER and change it to [3]UMTS_GSM
11) Press menu and back until you are in the PHONE CONTROL menu and select [5] SIMULATION , press the [2] SW WATCHDOG button 6(six) times and then the [3] HW WATCHDOG 6(six) times. Nothing will happen at all to let you know if you have done this correcctly but as soon as you finish the sixth press on HW WATCHDOG reboot the phone manually:manually:manually IMMEDIATELY . I’m not sure what this does or why this works but @nicotheandroidguy seems to have divined that this is the vital part of the process.
YOUR PHONE STILL WILL NOT HAVE DATA OR VOICE WHEN YOU REBOOT FROM THE WATCHDOG TAPS DO NOT PANIC!!!!!!!!!!! (hopefullly you have your towel with you)
12) WIFI that sonofa up and search for apn settings shortcut and build.prop editor in the Play Store.
Go into the build.prop editor and add the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
REBOOT PHONE MANUALLY now.
Now Install and create a shortcut on the home screen and select to open. Press the menu soft key and select add apn.
Use:
Name: T-Mobile
APN: epc.tmobile.com or fast.t-mobile.com (for LTE devices)
Proxy:
Port:
Username:
Password:
Server:
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy:
MMS port:
MMS protocol: WAP 2.0
MCC: 310
MNC: 260
Authentication type:
APN type: default,supl,admin,dun,mms
13) Go into your android settings, select wireless networks, you should see the network mode set as wcdma only do not change this, we set this in the Service Mode Menu , Check that your roaming settings are set to for roaming data/ international data etc.also make sure that there are no roaming guards left on. (roaming guards will only allow you to uncheck GSM and GSM data under international roaming.)
14) reboot
15) profit
At this point I had full access to the TMOBILE UMTS/HSPA+ network and voice/text/mms were working.
At this point you may change roms, be careful not to update past mf9 as you may be unable to downgrade to mdc. YOU MUST DOWNGRADE TO MDC MODEM FOR THIS TO WORK.
If you use a non touchwiz rom you can still access the tellinfo menu by pressing *#*#4636#*#* and selecting WCDMA only and manually adding the apn.
GOOD LUCK! let me know what needs changed in the guide as well.
If you have questions it's useful to know your Baseband /kernel/ rom.
Nice. Will it work with t-mobile in Los Angeles?

My 1st newbie post:
Thanks for OP's excellent post!:good:
I have a Sprint Galaxy S4 is with stock MF9 (not unlocked).
I have spent days reading about how to get a rooted/unlocked MJA S4. But still could not find answer to the questions:
1. Will this also unlock international sim?
I guess yes, as domestic is harder to unlock. But want to hear the confirmation.
2. You mentioned you used MF9 rooted.
If I unlock it, then update to MJA, will that void the unlock?
3. Does this unlock works with MJA? If it works, do I need to unlock MJA first?
4. If I want a rooted & unlocked S4 with stock MJA, what is the simplest way and the correct order to achieve this goal?
Can I update to MJA, then root, then unlock?
Or do I need to root the MF9, then unlock, then update to MJA, then root?
If I update to MJA first, I can't go back to MF9, correct?
Thank you very much!

Ok
1)i am unsure of whether mja can be unlocked internationally or domestic . If you read the first direction it actually instructs you to downgrade to mdc modem. I'm pretty sure the reason has to do with the options available to you in the hidden menu.
2)i used mf9 rooted as a starting point to downgrade to mdc to perform the international unlock. Autoprime said in the thread that upgrading to mf9 would keep the u lock however I haven't successfully upgraded to mf9 and kept the domestic unlock. I'm going to try to get it to work today but not with mja until there is a reliable downgrade option.
3)i have no idea. I wouldn't suggest trying until there is a reliable downgrade option.
4)i would really slow down and read the international unlock guide from @autoprime I think it will answer a lot of your questions. Like I said I would wait to upgrade to mja if you want a for sure domestic Sim unlockunlock.
Thank you very much, imbmiller.
I will just wait patiently for the MJA solutions before upgrading to MJA/root/unlock.

So would this also work for AT&T sim? has anyone else tried? Btw, was thinking of updating to 4.3 and MJA but i guess i will have to hold off on that if i want sim unlock international or domestic? I am on MF9 with sim international unlock right now. Would I have to go down to MDC to get this to work?
Also, if you want to go back to sprint again, how would you do it?

You can use MF9, MDL and MDC for the domestic unlock.

Hi thanks so much for putting this together all in one place!
Hi I'm on MF9, rooted, locked.
So really the two major steps are:
1. Do int'l unlock first (autoprime)
2. Then do domestic unlock
My question - after you get both unlocks working and say you have your phone working on tmobile, what do you need to do to get it working on Sprint... rather, is the phone operatable on both Sprint and Tmobile? Or do you have to do some tinkering to get it back to working on Sprint again. I'd like to have the flexibility of popping SIMs in and out and switching carriers at will, Sprint included (b/c I don't want to cancel Sprint just yet...eventually, but not immediately). Thanks!

Another question
When you're tinkering with swapping out modems and APN settings, does doing a nandroid backup prior help so when you have an "oh sh!t" moment, you can just do a full restore...? Or is what's backed up in nandroid outside (excludes) these changes? Thanks.

OK the answer to the first question is to put your sprint sim card back in then put your phone back in to lte/cdma auto through the tell info app through Google play device info then change it in to lte/cdma auto.
Answer to the second question is that the nandroid might help you in a oh sh!t moment but the modem and settings for the unlock stay after a factory rest but a other update could kill it. A stock Odin flash and dailing ##72786# could also kill both unlocks.

Nevermind, it works on Metro it just matters the SIM http://forum.xda-developers.com/showpost.php?p=47624568&postcount=568
Did you install hiapn and add the apn? What baseband are you on? What rom and kernel? I'm not super positive about mvno s but I'd probly go back to the beginning and start over.

Sorry I had to edit my post. It did work. There are two different GSM SIMs the one with the dot seemed to work. I Got Edge, 3G, and H+. It is awesome. I also still have 3G with Sprint with the SIM in. I got two phones in one. Thanks.
So I've been on T-Mobile for the last 24 hours but my HSPA+ signal is weak and slow (under 1mb), while my co-worker on T-Mobile (and a T-Mobile phone) has full HSPA+ signal and speed (5-9mb).
Any thoughts on what could be the cause?
I'm running CM11 on MDC. I'll try some other combinations tonight to see if things change.

HTC M8 3G/4G not working

Greetings. I've got a sprint har/kar m8 s-off (sunshine) latest bad boyz 2.1. Thanks to OMJ I got sim working in europe, but the only working mode is GSM/UMTS and automatic which is choosing the same. Therefore I don't have internet trough my operator ( wifi is working ofc )
I guess it because we have different band frequencies or something like that but is it possible to fix this, because this is starting to annoying me a lot!
As using it in Europe I wish to have nothing in common with SPrint, Is it possible to put a ROM not for sprint or edited one without any sprint stuff? I am paranoic type when it comes to phones , are there kinda "anonymous" rom which fit my M8? I think I am ready to turn back Google Play and all these stuff...... They are really annoying when it comes to access.
Thank you!

Thank you for your answer! I tried it several times with no luck.
Please note I have sim unlocked my phone while a go (thank you) using these instructions http://forum.xda-developers.com/showpost.php?p=52145162&postcount=2 . My phone is having signal and I can talk but no internet at all.
When i turn on mobile data under it is shown
Code:
Disconnected because service is unavailable
. Inside the Menu on the first option
Code:
4G settings
under network provider i see mine. On
Code:
Access point names
are shown 2 APNs - wap-gprs.MyProvider. and mms-gprs.Myprovider. Manual search for networks is also working (shows me all operators here and a yellow star for mine)
In your guide you have to change a system .apk file which is otherwise patched automatically if you use the guide I have done myself before. Which only says me mine has been already patched when I followed your guide. Anyway I have replaced it and done everything but still no connection.
I saw @Cashreedhar (first guide I used author) says its Permanent and until now after several formats and rom changes ( tried venom 2.4 but went back) I haven't got gsm signal problems so far. I really doesn't understand why the magic is not breaking after reinstall (changing rom) (does the patched .apk stays or no) but its also gives me a clue I may be have already messed up something.
Excuse me for my confusing language but I am also confused and that's how it looks like :laugh:
My noobish logic ends here, waiting for lolipop 5 and try again : )))))))))
Any help would be greatly appreciated.
Thanks.

Hey if you followed the procedures, everything should be fine in there. Try adding apn manually for your network and force HSDPA. If you get 3g signal, you should also be getting the internet.

[INFO][HOW TO] Sprint Galaxy S4 Sim Unlock (SPH-L720/jfltespr) ATT/TMOBILE

There seems to be some confusion on the matter here in the forums.
Can I sim unlock my Sprint Galaxy S4 to use ATT/TMobile sims?
Yes
Can I do it using a Lollipop Rom?
Yes
Can I do it once I flash a KNOX bootloader?
Yes
Can I do it on OD2?
I don't think so, but maybe... The best bet is to use NG2 and then experiment from there...
Can I do it without reading/paying attention/following directions?
No.. but if you made it here, you're doing OK so far...
First off, there are 2 kinds of SIM unlock for the SPH-L720. International unlock, and domestic unlock. We will cover both.
To unlock for international carriers SIMs, you have a couple of options.
a. Have sprint unlock it for you
b. Do it yourself.
I prefer b, almost always.
Lets start off with what you'll need:
Drivers for the phone, I'm too lazy to find those, but if you can't, you are way out of your depth here.
SSU.apk from here.
An NG2 Stock Rom (modem and ROM) here is an Odin tar that i used when I did it.
Odin from the same post that tar came from... (here)
TWRP recovery in tar format from here (i used 2.8.4.0, but I don't think that matters)
adb ( i use this minimal adb installer but any adb install will work.)
THIS WILL PROBABLY WIPE ALL YOUR DATA.
Put your phone in Download mode (Power + Vol Down)
Open Odin
Click the PDA button, choose the tar.md5 file you're flashing. (the stock ROM from earlier)
Uncheck Auto Reboot
Plug in a decent USB cable, from the phone to the PC
Hit start
It will take a few minutes, no worries unless you get an error.
When it is done, Hold Power + Vol Down until the phone reboots into download mode again
Click PDA in Odin and load the TWRP tar you downloaded earlier.
Hit start. This will take significantly less time.
When it is finished, Hold Power + Vol Up to reboot into recovery.
When TWRP is fully loaded, click reboot then reboot system.
It will tell you that the ROM is not rooted, and ask if you want to do that. (if you used the tar from above) and of course we want to, so let it.
Let the phone fully boot up.
Goto Settings, More, About Phone.
Find the line that says Build Number, click that line a bunch of times until it says "You are now a developer".
Now hit back, and goto Developer Settings.
Find Debugging mode and enable it.
Using adb
Code:
adb devices
that will respond with whether it finds your device or not.
Code:
adb install /path/to/SSU.apk
that will install SSU.apk from earlier..
You'll want to have the screen of your phone on for this part because you will need to approve your PC to connect.
Goto your app drawer, and run SSU
Click the Unlock button
Now your phone is SIM unlocked for international carriers... But what if you want domestic carriers too?
Unlocking for Domestic Carriers
First things first, you have to do the International Unlock explained above (you didnt think you were gonna get out of that did you?)
After that, load ADB back up
Code:
adb shell
Code:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
That will pop up a menu on your phone
Click (UMTS) then (DEBUG SCREEN) then (PHONE CONTROL) then (NETWORK CONTROL) then (GCF) then the top option.
Now reboot.
You are now unlocked Internationally and Domestically. Goto your mobile network settings and put your apn settings in (if they arent already there off the sim) and you should have data too.
From here you have a couple of choices.
a. Stay on NG2
b. Goto another ROM (i usually just flash CM at this point, YMMV)
c. experiment yourself and try to use OD2 (I've heard flashing the OD2 modem relocks it, didnt try because I didn't want OD2)
If you stay on NG2 then I suggest this apk to Stop the Sprint Hands Free Activation from nagging the **** out of you..
NOTE: as of tonight, any CM12.1 nightly after 6/23 causes a No Sim card error. This has nothing to do with the unlock, its just messed up, so until its fixed use the 6/23 nightly.
Hopefully that answers some of the questions I keep getting in PMs and what not.. If you have any question, feel free to ask.
I might not answer them, because I rarely frequent the forums anymore, but lots of people here can probably answer the questions you have.
Thanks to @autoprime he's the one that found the original unlock for this phone, and tons of others.
Thanks to @random45 for posting the ROM i used
Thanks to @shimp208 for posting (making?) the minimal adb install that i use
Thanks to @Sloosh for making the Hands free activation disabler apk
Thanks to @Dees_Troy for TWRP and just being cool in general
Thanks to @aalyatim for the SSU.apk
Thanks to cyanogen and Team CyanogenMOD for all they do..
Thanks to @imaxuout for keeping this topic alive in a few threads
Thanks to @AndroidKing for a similar thread.
Thanks to nicotheandroidguy also.
And anyone else I forgot (I'm sure I did)
I would probably recommend removing all references to rooting since it's not necessary. Some may only want to unlock, not root.
Substitute the dialer code for the terminal command when it comes to launching the service menu.
And putting the apk on the phone's storage and installing it with a file explorer is probably easier than adb install, for most people.

I just documented what I did. there is no one way to do it. you are more than welcome to document them in your post if you want.
I'm going to try this today and will report back. I switched to tmobile and got the s6 edge and since my sprint contract was up I was able to keep my device. Now I want to get it to my mom who has a beat down metro pcs device. In theory since metro is tmobile it should work right?

If metropcs uses sim cards, and the Bands that the GS4 has, then yes it should work. You'll obviously need APN settings for data.
So this method you need to be on KitKat in order for Suu to work. I also can't get a hold of galaxytools as the developer wants you to buy it now.
Also any ideas how to do the domestic unlock without adb?
Sent from my SPH-L720 using Tapatalk
I don't use galaxy tools, and if you aren't on kit Kat yet, you can revert the modem and use the original unlock posted by autoprime.. Or you could just flash the rom I linked too, which is lollipop, not the newest but works fine.
And as far as adb, you can just use a terminal app.. Except for installing ssu.apk, but you could just push that to your phone and install it with a file manager
I followed the above steps and still can't get it to work. Im back on kitkat and unlocked the sim. Did the terminal command and followed those steps. rebooted and under About Phone> Status it still says sprint and shows my old phone number that was tied to my sprint account. Am i missing something? I went to settings and changed to gsm/utms and tried that but nothing.
Did you put a sim card in?
Yes it was a metro pcs sim. I spent a couple hours tinkering with different steps from older threads and still could not figure it out.
Metro is unique in that you can't switch phones just by popping a SIM in.
You have to contact them and have them register the new IMEI to the phone number

How are Data speeds?
This is great thank you for posting this detailed one. If i can't figure out how to get my phone working right I'll flash stock firmware and start OP's process. Can you tell me what data speeds are you getting? I've got mine unlocked and working by changing my modem and using s4 flasher among changing other settings. It's a Sprint S4 L720 going to Tmobile. I'm only getting Edge speeds of .08 mbps and the voice is sometimes garbled. I'm not sure how I can get it unlocked and working well with everything working and getting the HSPA+ speeds. I live in a 4gLTE area so I should get at least 3g speed according to tmobile's coverage map using 72703 zip code. Trying to figure this out if anyone has suggestions on how to get out of EDGE speeds, the 2G EDGE capabilities are appalling. I haven't flashed any custom ROMS btw.

I only used it on att, but if your speeds are low then TMobile in your area probably operates on a frequency the s4 doesn't use.. Or your apn is wrong, idk which.

1. Make sure modem version matches software version
2. Make sure network mode is set to WCMDA preferred or GSM/UMTS.
3. Check Settings->About phone->Network to make sure you're actually on EDGE.
You could live in an area that T-Mo hasn't refarmed to 1900 yet. If that's the case, they're running HSPA on 1700 there, and the phone doesn't have that frequency. So that would explain only being able to get EDGE

Nexus 6 - T-Mobile - Not connecting to LTE

I just got my wife a Nexus 6 from Craigslist. I foolishly didn't 100% test the phone and I think I got a lemon or something.
Her phone has never connected to LTE. I've tried manually changing APNs, swapping SIM cards with my phone to see if the card is bad, checking the phone settings by dialing *#*#4636#*#*, etc... And everything is identical to my Nexus 6 with no luck. I went to a T-Mobile store just now and they couldn't figure anything out.
Two questions:
1. Is there anything else I can do to get LTE activated?
2. Can an LTE radio be damaged or disabled somehow?
I'm at my wit's end here... I'm hoping y'all can help me get it fixed.
Thanks!
1st is the phone running stock or a custom rom? .second try to reset your apn setting to default and using the setting that the phone provides in apn
It is stock, no customization or rooting.
I'll try the default when my wife gets back from the store and report back.
Reset APN to default settings, no luck.
The previous owner was on a smaller carrier, like a Metro PCS or something similar... Can't remember, but I don't know if their settings are different than T-Mobile's.
Yes their settings are diff... metro is fast.metropcs.com for apn inside and tmobile is fast.t-mobile.com. You can try clicking the apn make sure its fast.t-mobile.com and check the ipv and set to ipv6 and ipv4 for roaming. Then at the very bottom under MVNO select None. Then restart phone. If your still not pulling up data you may want to push a radio image to the device possibly and maybe the radio firmware is screwed up since your not original owner of the device.
All the APN settings are correct and identical to my working Nexus 6.
Are there tutorials on how to push a radio image and where to get said radio image?
https://www.androidpit.com/how-to-update-nexus-5-bootloader-and-radio - Nexus 5 instructions but they are the same just download nexus 6 files instead from here
https://dl.google.com/dl/android/aosp/shamu-mob30i-factory-21357b09.tgz - MOB30I Latest Marshmallow files...
When you follow that guide you could just flash-all command it and flash marshmallow stock in its entirety... it would flash latest bootloader and modem with it or you can extract the modem and bootloader files from the file and follow the guide. If you dont care whats on device you may want to just flash the whole thing and skip the extracting the modem and bootloader parts.
**Obviously since you'd be replacing the nexus 5 files with 6 files aka shamu instead of hammerhead change the names in the commands you type in fastboot. Just a reminder.
Thanks so much for the help!
I'll try this later and let you know if it works.

Enter into the bootloader and check the Product/Variant information within. For the US, it should read "shamu XT1103" followed by the memory size and a hexadecimal string. If it reads "shamu XT1100", you have the international model, which would explain the trouble you're having. Another possible explanation, especially if the model is "shamu XT1103", is that the device is blocked on T-Mobile.
To answer your questions:
1. If you have an international model, you may be able to activate the missing bands necessary to support LTE here in the US. Otherwise, flash the latest ROM from Google, as there are settings in the services menu you accessed which once selected cannot be changed unless a new ROM image is flashed.
2. LTE radios can both be damaged and disabled. The LTE could be disabled in the service menu, or the hardware is damaged.

I have same problem. I have XT1100 on T-Mobile, but I can only use 3G. How to see which LTE bands on this devices are activated?
If you have an XT1100 in the US you're missing bands 2, 4, 12 and 17. Of those, bands 2 and 4 are the most important as AT&T and T-Mobile both use those bands extensively. And unlike the US model, Verizon and Sprint won't work at all. Search the General forum, as there is a thread on how to add bands to the radio. Be warned however. When I attempted it on my Galaxy S4 I nearly bricked the device.
Also (and I know its basic) but check under settings ---> mobile ---> preferred network type and make sure it says LTE (just on the off chance it was switched somehow)
