Help plz. Wind sgh m919v

Hi there..
All of you masters out there. I just jumped from an iphone to s4. And got this S4-SGH M919V from WIND Canada.
I am a newbee to Android. Now I have been searching if there is a way to enable LTE in my S4. I am facing the exact same problem as my friend posted above. I have tried enabling LTE through ×#2263# command. It does show an esterik infront of LTE bands once selected butttttt I cant make calls.
Now I think this is happening because Wind model of S4 which I have does not support the LTE band frequencies...
My question is if there anyway I can flash the modem firmware from T-mobile which apparently has all the LTE bands in it????
Will that enable LTE in my S4??
P.S I have not rooted or done anything yet with the phone. Just got it unlocked through Wind mobile.
Phone details are as folows..
Wind S4.
Device name : SGH M919V
Baseband : M919VVLUAMG1.
I am currently using wind mobile sim card with 4g speed on it.
I really need this LTE enabled. Because when I put a Bell sim in my phone. It connects data with 3g. Its not showing LTE at all. And when I tried forcing LTE with bell sim inserted, the LTE works fine but I lose the calls.
I would greately appreciate any guidence here. Thank you.

[Q] AT&T device LTE VS T-Mobile device LTE

Hi, Does any know if its all vice versa?
AT&T LTE phone and T-Mobile LTE phone using it with a T-Mobile SIM, (vice versa) T-mobile & A&T LTE phone using AT&T SIM?
(Both LTE phone is same model type also unlocked & using in urban BIG city)
Will there be any difference speed LTE and speed 3G & 4G you receive?
Will the LTE signal not be as strong each other?
Will be any problem each other (vice versa)?
Which hardware AT&T or T-Mobile device (same model) is better having multi-LTE or more compability network each other (freq band spectrum)?
I don't really know much about LTE signals between AT&T and T-Mobile, compatibility, etc. So, I was wondering if you can help me to decide which one are those? How long to get unlock code from the 1st day i purchased with full price AT&T and T-Mobile device?
Please...please... help for answer & information. I'm very appreciate and thank you so much for explanation everything. :good::victory:
P.S. Sorry & apologize about my bad english

[Q] verizon galaxy s3 on tmobile network help

Hi guys, so my mom has her gs3 on verizon and she bought a sim card for tmobile. We activated it and we get Edge data speed but nothing more. We live in a LTE area with great service but we just have edge. how do i get her data to LTE or HSPA+? Also when entering *#*#4696#*#* i dont get the option to change the LTE/CDMA radio like i use to

The vzw gs3 is not compatible with T-Mobile. Be glad you get edge
Different radios in the devices.

+1. Edge is all you can get with any non Verizon US carrier.

[Q] Whether does I535 support Tmobile or ATT WCMDA

I just bought a I535, unlokced and rooted. But seems it can't support either ATT or Tmobile WCDMA. Ive set up a correct APN, but it can only work under Edge network.(no signal if I change to WCDMA only) Is there anyone who use Tmobile or ATT? How can I do? ROM 4.1.1 VRBLK3

Hey lil buddy, i have probably 6 galaxy s3's one being my i535, and its my most pristine condition Gs3, i use a i747 which is an ATT GS3 as my main phone, all are unlocked, now from what i know about the i535 and i hope im wrong, is since its a CDMA phone, it doesnt support the same bands tmobile and att use for 3g/4g/LTE data, my i747 is on straight talk and works awesome, 2 of my tmobile T999's work awesome aswell, but only get HSPA+, which is 4g, but from what i hear on our i535's we cant get anything above EDGE when running on Tmobile or ATT.....i hope you find a solution cuz if you do please tell me!

Thanks in advance

Duos g920FD is same geographical version as international g920F (except it is single SIM), same 3g and LTE freqs.
There is a T - Mobile version for s6 (g920T), only single sim, there is not duos t - mobile version.
It means probably your carrier is using 3G 1700MHz freq on your zone, the only additional frequency that g920T has and g920F/FD hasn't. Both versions have same LTE freqs except F/FD versions has 3 more LTE frequencies available, because this you have not problems with LTE.
Check with your carrier if they are using 1700MHz 3G band and if so, sorry, you should change any of your carrier or your phone, or force GSM connections. Or maybe you can also configure your duos s6 using a non T-Mobile SIM for data 3G/LTE, and your T-moblie SIM as 2G (GSM) only voice/SMS.
