Hello, and thank you for using XDA Assist!
The 920i is the international model, and thus misses Band 4 (1700mHz) which is used by the USA GSM operators (AT&T, T-Mo, MetroPCS, et cetera). This means you won't get 4G LTE with this device.
Also, if trying with T-Mobile, they alos use 1700mHz for HSPA (3G), a frequency your device does not have either. So unless T-Mo still supports 2G (I remember a planned phasing of that out at some point), your device will not work with their network.
AT&T on the other hand, uses 3G 850/1900 frequencies, so you should be okay.
At any rate, I could be optimistically wrong. So, please create an account, so you cna post in other forums, then either post in the above linked thread, or in the S6 general help thread:

hey,
i am from India. My friend is going to gift me samsung galaxy s3 (unfortuantely and probably its t-mobile) from United States. i've no idea whether they are CDMA or GSM carrier. if its CDMA so my questions are :
can i get an unlock code which allows me access any gsm networks in India.?
And if it is GSM one, can i access 3g networks in India.?
i have read in a random forum that if its gsm carrier i can only use EDGE service in India.
AND the last one-
should i update official ics stock rom firmware for INDIA OR for The USA?
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.

Hi,
I have a problem with my S5 and I was wondering if I could find any help in this forum. Excuse me for my English and if I am not posting in the correct section, is my first time in the forum.
I live in Lima, Peru and I recently bought an Unlocked Samsung Galaxy S5 model G900W8 from GSM Nation in the USA.
I choose this version of the S5 since it was unlocked for the bands in which my operator (Claro) works here in Peru (2G: 1900Mhz, 3G:850Mhz and 4G: 1900Mhz (Band 2)).
When the phone arrived, I just changed my microSIM card from my old phone to the S5 and it worked without any problem, I was able to make calls and navigate normally. But since my plan was only a 3G plan (since my old phone didn't support 4G) I decided to upgrade to a 4G plan. I went to make the change and my carrier informed I also needed a new microSIM to use a 4G plan, and I did so. But when I plugged in the new microSIM the phone it doesn't work. It shows the message "Emergency calls only" and when I try to call it shows "Not registered on network". I called my carrier for support and they said they have already made the change and activated the new microSIM and that they can't give me any further support since they only sell the Galaxy S5 G900M with their plans.
I don't know what is causing this problem, but I think it must be something related to my carrier that is blocking my phone to access their network but only with the 4G plan and microSIM.
Thanks in advance for your help.
Hi there!
If I had to guess, I'd say its 1 of 3 things,
1. An account problem with your carrier.
2. Your APN setting for the new 4g network are not right or missing. You'd have to find out from your carrier what they should be.
3. Simply a bad sim card.
All of those need to be discussed with your carrier though.
However, feel free to ask in the S5 Questions and Answers section. Perhaps someone there can offer other ideas.

Good luck!
I have an unlocked Verizon LG G4 VS986, I have an AT&T sim card in it and can make and receive calls and texts just fine. I also have internet but it's showing the H symbol and an up and down arrow below it. I have speed tested it in many places including my house and it is slower than My At&t s6 edge was while using the data. I checked a bunch of places and the APN settings seem to be correct. Why am I not getting 4g or lte speeds when I was in the same places with my At&t branded S6 Edge? Can anybody help me atleast get hspca or lte?
Thanks
Hi, thank you for using XDA Assist. Unfortunately Verizon uses a different LTE band than other carriers. Their hardware often only supports that band. You can see if other users here can help, http://forum.xda-developers.com/g4/help There probably are as this is a common question regarding Verizon hardware on the AT&T network.
So I bought this Samsung Galaxy S6 Duos (Unlocked) [SM-G920FD] from Swappa but can't seem to get it work with T-Mobile at all! I'm hardly getting any bars plus network keeps dropping off. Funny thing is I live in a T-Mo zone, my other phones (running on T-Mo) work without any issues. No Problem with LTE either.
I'm super frustrated and donno what to do anymore.
What apn setting do I need to use? I will really appreciate it if anyone can kindly help me out with detailed instructions, since I'm a such a dumbo!
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.
