[Q] CANADA Ability to tether on Wind AWS network using TMobile T889

Hi All,
I currently have a rooted TMobile T889.
I have a quick question in regards to using the TMobile based phone on the Wind network here in Canada.
After searching, I found WarlockW's instruction post on updating the APN's to remove the lock in order to utilize the hotspot for the Tmobile SGH-T889 G Note II Reference Here ---> Remove The Locked & Hidden APNS & Tethering T-Mobile APN's! - New Updated XML
However, in the instructions provided in the above link he states "for TMobile users only."
this left me confused and lead me to posting here. Does that mean for that the modification linked above is for TMobile Network users only or TMobile Phone users only?
With a TMobile based T889, what is my best option to tether using this device on the Wind Canadian AWS network? Would I be better off flashing the phone with a Wind stock ROM? If so, where can I find a copy of the Wind ROM for the T889 (Searched)?
I haveunlimited data [fair data policy usage after 10GB] with Wind and also already pay for the tethering option as well.
Thanks!

I'm with mobilicity in Calgary and tethering works with the jedix8 rom....no mods but did delete the proxy in Apn

Off the top of my head:
-Carriers can lock APN settings through CSC.
-If Wind uses a separate APN for tethering (didn't bother checking) make sure its entered properly.
-Use whatever fixes that may be required beyond APN changes (Removal of T-Mobile-specific APNs may still be necessary.) on the US T889 ROM, or, if you're going to start flashing stuff anyway, consider using a T889V, N7105 or I317(M) based ROM which have none of those restrictions.
A broad, over-generalized statement I've made before is that if you have a choice, odds are that the Canadian or International ROMs have less restrictions, branding and bloat than their US counterparts. I understand some carrier-specific features like Wi-Fi calling muddle the waters, but this isn't a concern here. And if you *do* want carrier apps, they're increasingly available from Google Play. (Or just download that carrier's stock ROM and rip them out. [Cue evil laughter.])
Good luck,

if you are rooted, simply download the treVee mod... that's what I use with T-mobile... you're just gonna have to edit the settings in the app to get it to work right. Simple apk download and install and ur set

I used the Jedi 8 ROM on my tmob phone. Tethering already enabled. Simple.

Vzw S4 to T-Mobile

I have a Verizon S4 sch-i545 running Hyperdrive RLS 19. I plan to switch to T-Mobile in December to save money. One cool feature of T-Mobile is WiFi calling but that's not included with hyperdrive.
I believe I can get T-Mobile service if I put in a tmo sim card and change the APN settings.... But can I flash a T-Mobile rom that has wifi calling on my Verizon s4? Thanks!

I think you might have to port the ROM, or flash a Verizon kernel.. Successfully flashing a T-Mobile ROM will give you Wi-Fi calling so try to search the Verizon forums if anyone has flashed a T-Mobile ROM and what their procedures were

Thanks serio22!

[Q] Note 4 already unlocked but need bit of help

I own a att note 4 already unlocked but I am thinking of going with tmobile for the wifi calling feature. This is where my problem lies ...is there any way to install tmobiles wifi calling features over the stock rom? I've been out of the rom scene for a long time and would very much appreciate any help that could be offered I'm at my wits end on this one.

If I am thinking correctly, the Wi-Fi calling feature is part of the ROM. You may be able to install a t-mobile rom on the phone, if you have a NON AT&T phone, as I believe that the boot-loader on the AT&T phone is still locked and there is no workaround yet.
I am currently running a t-mobile note 3 on AT&T and the Wi-FI calling feature is not possible on AT&T service.

[DOMESTIC][UNLOCK] Domestic GSM confirmed working on some AOSP roms

I can confirm that you no longer need to use the much outdated CM11 T-Mobile ROM, T-Mobile Stock ROM or the RayGlobe Flex ROM in order to use a USA domestic sim such as T-Mobile. I noticed that the BUILD.PROP on the T-Mobile CM11 ROM has some enabled goodies which do not come on the default CM11 for the LS980. That made me wonder what if I use a unified ROM (built for all variants) instead of the ROMs available on the Sprint G2 section? The build.prop there will still include capabilities for GSM devices, which CyanogenMod seems to strip in order to avoid switching to GSM (correct me if I am wrong). Anyways I gave it a go using the LS980 Bliss Pop ROM based on 5.1, which is found in the non-carrier specific section of the G2 Android Development, and sure enough I was back to being a Sprint device. Using the dialer, I accessed the Testing menu by dialing *#*#4636#*#*, switched to WCDMA preferred, and it seemed to have revert. Then I clicked WCDMA only and it stuck and I could see my signal bars changing. THEN I switched it to GSM/LTE and FINALLY HSPA+ appeared. Calls, texts, data, it all works as the APNs were already auto selected. MMS DOES NOT WORK. I've been using it like this for the past couple of hours and no issued so far. I cannot remember if I did the official unlock available on our section of XDA as I've had quite a few of the Sprint version on and off, but I really do not see what role that plays in the matter. If it doesn't work for you, then you probably do need to use the official unlock.
***Again, if my theory is correct, this should work only on unified ROMs, which are ROMs compiled for all/multiple variants.
It never worked for me on stock CyanogenMod ROMs for the LS980, thus my theory. Another theory I have is that since Sprint now allows domestic unlocks, these phones may be free to enter the domestic side if you can get them to recognize a domestic sim...
If you want pictures/proof, ask, its about 5am in my time zone and I'm too lazy to take them and upload them.
If you want to force HSPA+ instead of HSPA, use the "HSPA+ Tweaker" app found in the Play Store.
If you feel like this is good news since you use this device on a carrier other than Sprint, remember to thank me.
If you are in another country and are willing to experiment, try it and I'll update my OP as soon as I can.
If you have already mentioned this in another thread, this is my own thread, started so that others can see it easier rather than having to accidentally stumble across yours in another thread.
EDIT: Can confirm it works on other AOSP ROMs. When switching network modes, you must have a stable data connection or else it will automatically try to connect to Sprint towers.
MMS DOES NOT WORK!

Outside the usa GSM sims works perfect on every not SPRINT rom (stock based like cloudy or optimus, or AOSP/CM based)

Thus the first word in the title of this thread is "Domestic". Back then, you couldn't get a USA sim working with those AOSP based ROM, heck you couldn't even use it if the rom wasnt modified to spoof the T-Mobile version, see for yourself the domestic "unlocked" roms I mentioned above show your device as a D801. There has always been the international unlock which can be used even on stock, but that wouldn't help USA users.

AT&T Branded Galaxy S9 SM-G960U - Can not enable WiFi Calling using T-Mobile Sim

Hello everyone,
Yes, I'm a noob here but online research, etc. tells me that XDA is the place for me. I am a IT tech, just not a programmer nor have I done a lot with flashing phones, etc.
based on some basic searching my issues seems to be common.
I am a T-Mobile user and I now have a new AT&T Branded Galaxy S9 SM-G960U. I paid a third party to provide me with a Samsung unlock code. I unlocked the phone last night, had T-Mobile update my account with my new Nano Sim, etc.
All is working except I can not enable WiFi Calling and of course there are some advanced text messaging features that I can not enable, i.e. sent receipts, etc. I tested the phone with a active AT&T sim and the features work fine.
Does anyone have a work around for getting WiFi calling and text features to work using the T-Mobile Sim?
Do I need to some how flash a T-Mobile ROM to the phone?
Any help and guidance would be greatly appreciated

it will never work because is att brand. you needed to get international model.

I'm not so sure.......... I have the SM-960u1 and have flashed various AT&T FW to it at least 50 times and cannot get any IMS features to work. I get get the ATT bloatware, software,splash screen. But no VoLTE, WiFi Calling etc. I am tired of flashing. Back to Stock U1 for me.

AT&T is the same. They keep promising wifi calling for unlocked phones but I can't get it and neither can 2 others I know with unlocked phones.

This sounds normal. I have an AT&T branded Galaxy S6, which has wifi calling, but I'm using a MintMobile (T-Mobile) SIM. Wifi Calling is grayed out. There's probably some sort of check in the software that only enables the wifi calling if you are using an AT&T sim.

Yes, you have to flash the T-Mobile firmware with the latest modded Odin, or the unlocked U1 variant firmware (for which TMO's RCS messaging and video calling won't work-with U1 firmware, I mean). If you flash the TMO firmware, it's for all intents and purposes turning the phone into aTMO phone, with bootscreen, bloat and all.

You will need to flash to the U1 Firmware then Flash the T-Mobile firmware. AT&T's Wifi Calling is proprietary and thus their phones software won't work with other Carrier's Wifi Calling.
