Rodger that ! That's REALLY good info because I don't think people know that I mean at list I ALWAYS tough that T-Mobile phone don't play with ATT and wise verse. That's why my favorite phone of all times was T989 cause no matter what I put in there I always get 3G/4G network and never EDGE. But now With i337 I guess I may have my new BFF.

Thanks !

The AT&T version has band 7 enabled on it. But I'm running on band 17

I have a rooted unlocked att S4. I am moving to Germany next week. I plan on using Vodafone which runs on 2600 band 7. Do I need to do this mod to access their LTE network?
[AT&T Samsung Galaxy S 4 General] romeoh:
it's a very simpler method than the first one since you only change the number value insted of flashing the whole qcn file, but the best thing about this method that it could be used on any version. I'm like you bro have tmobile sim, but the coverage in area is amazing and I don't really miss the wifi calling feature from t mobile roms at all, which we don't have in our rom.

I run this rom on my I337 phone on T-Mobile and wifi calling is in the rom.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can flash a T-Mobile ROM and get Wifi Calling. That's how I used to use my AT&T S4 on T-Mobile. The T-Mobile ROMs also give you a Network Mode menu.
[AT&T Samsung Galaxy S 4 General] romeoh:
Thanks buddy, As I mentioned in my previous post that I don't miss the wifi calling because I live in LA and the coverage here ar awsome almost everywhere around me, and about the network mode it's still available on our rom but At&t hide it. All what need to do just dail *#2263# on the keypad to access it. ?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I meant for anyone who needs it. Also, if you use that menu, and choose, for example "WCDMA Preferred -> 1700 MHz", you're telling the phone to only connect to HSPA+ 1700 MHz (no calls/texts/EDGE/LTE). You have to hit Menu button -> BACK -> Automatic.
[AT&T Samsung Galaxy S 4 General] kb8no:
The LTE AWS band (AKA band 4 = 1700 = 1700/2100) seems to be rather important in North America. For example, it is the primary LTE band for Tmo and the secondary LTE band for ATT, Rogers, and Verizon according to my understanding. The Tmo M919 certainly comes with this band enabled since it is the primary LTE band of Tmo. As far as I know these things ship with LTE 700 / 850 / 1700 AWS / 1900 (17, 5, 4, 2). However, can someone confirm that the ATT I337 comes with LTE AWS enabled?

What LTE bands does the Rogers I337M come with? I cannot find this information when I Google it. From what I understand, Rogers uses 2600 = band 7 and 1700 AWS = band 4 for LTE.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I can confirm it. AT&T and even Verizon are starting to use AWS LTE to complement their 700 MHz networks (Bands 17 and 13 respectively) because, while 700 MHz carriers a strong signal, it sucks at capacity (AWS is the opposite). As far as I know, the i337M is the same as the i337 in terms of supported frequencies.

This mod is for enabling AWS HSPA+. For T-Mobile US, it's not really a huge deal anymore since any place with LTE has HSPA+ also running on 1900 MHz (they're repurposing their AWS spectrum for more LTE; more bandwidth = more capacity). So you technically don't need this mod anymore in most cases. However, the carriers who use AWS HSPA+ in Canada (e.g. Wind) not only do not have a secondary HSPA+ frequency like T-Mobile, but also do not have an EDGE network. So if your phone doesn't have AWS HSPA+, it flat out will not even SEE those networks.

Hello,

Long time lurker, rare poster.

Does it matter which build version of QPST we use?

i.e. can we use the build version 402 instead of 323?
[AT&T Samsung Galaxy S 4 General] kb8no:
I want to say I have been lurking here for long and I really enjoy and appreciate your contributions.

So you believe i337 has LTE band 4 AWS band but not positive?

So Rogers uses 2600 LTE and clearly not on i337 bands so LTE must be different between the two. I want to get a Rogers pay as you go when I travel mainly BC and Northern ON as they seem to have the best coverage.

Where I'm going with this is 2600 is likely a secret band. I need it for Canada (and Europe). The guys in the other thread are adding LTE bands. Any way to add 2600 LTE to the i337? It has got to be there. I got to believe there i337M guys who could use some some US LTE bands when they are traveling on this side. This phone would be a bomb if we could figure this out.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The phone 100% has AWS LTE. All AT&T LTE devices do. In the case of Verizon, any device that supports XLTE (that's what Verizon is marketing their AWS LTE as) also supports it, though their phones are more finicky (they hide THE APN menu on some phones, and other sneaky things).

I owned an i337 and used it on T-Mobile. It got LTE without the mod, though I did the mod anyway because AWS HSPA+ was more prevalent back then (I have a T-Mobile Note 3 now). Rogers uses AWS LTE actually. Their secondary frequency is, as you said, 2600 MHz (I think they sell this as Rogers Maxx), though that frequency is really useless because it's so high, it won't penetrate walls well at all and won't even cover a large area. I'm could swear I remember reading that the i337 does 2600 GHz because a guy in Germany showed me a screenshot in another thread (Europe uses 800/1800/2600 MHz for LTE).

You have to flash the MF3 modem in RockRatt's thread to get this mod to work. Its the only way to get AWS HSPA+ to work on the i337.
[AT&T Samsung Galaxy S 4 General] destructionj:
Aws for i337 newer roms (nj4) 4.4.4

MF3 modem will not work on NJ4. the phone will not work, also, QPST will not connect to the phone if you flash MF3 onto the phone. MF3 will work on 4.4.3 but not 4.4.4 NJ4.

Install QPST Setup build 323

Find the program RF NV Item Manager in the QPST folder and open it

Read the values on the phone under the File option(File-Read from phone)

look for line 1877 and change the number that reads 82314112 to now show 115868544

line 1877 should now read 115868544

THEN

Select FILE and then WRITE CHANGED NV ITEMS TO PHONE.

WAIT FOR A FEW SECONDS WHEN DONE

then install a app called terminal emulator onto the phone

Use terminal emulator to enter command

su

Then enter command

setprop persist.usb.eng 0

then reboot the phone.

Root access is needed to do this method as terminal emulator is used. This is the method i used and it worked. The 1st post is outdated and no longer works on new roms. Flashing MF3 onto newer roms also no longer works.

I was pointed to this method by Product F(RED) and after some trial and error, I came up with a working method using some logical reasoning after reading the thread at "Unlock all bands of your Qualcomm device."

http://xdaforums.com/crossdevice-dev/sony/thread-progress-please-leave-im-updating-t2871269

If you look back to post 1141 on this thread, you can see how this method of discovery was introduced into this thread.

Post 1145 briefly explains what I did to get the method described

The following bands report as active when 115868544 is entered into the band preference tool I used.

[Bit_07] GSM DCS 1800 band

[Bit_08] GSM Extended GSM (E-GSM) band

[Bit_09] GSM Primary GSM (P-GSM) band

[Bit_19] GSM 850 band

[Bit_21] GSM PCS 1900 band

[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band

[Bit_23] WCDMA Band II - US PCS 1900 band

[AT&T Samsung Galaxy S 4 General] kb8no:
So if the i377 ATT has a working undocumented 2600 (band 7) then likely the M919 Tmo also has this feature. We know the i337M Rogers has the 2600. Therefore, I have the following bands for these phones and they are probably all the same except only the M919 Tmo ships with the AWS band 4 activated.

LTE 700 / 850 / 1700 AWS / 1900 / 2600 (17, 5, 4, 2,7)

WCDMA 850 / 1700 AWS / 1900 / 2100 / (5, 4, 2, 1)

After we activate the AWS band 4 in the i377 and the i377M using the tricks from this thread then all 3 phones have identical bands. Would you agree this is most likely correct?

You say "Europe uses 800/1800/2600 MHz for LTE" A new European delivery USB modem listed LTE 800 / 900/ 1800 / 2100 / 2600 MHz (channels: B20, B8, B3, B1, B7) but maybe 900 and 2100 are Aus or Asia. Would there be any way to activate 800 and 1800 LTE so we could use these devices in Europe on LTE using this same method? I was not able to get LTE using Vodafone in The Netherlands this past summer on my S4.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
Don't do this with the Sprint version. This mod is only for the i337 (AT&T) and i337M (Rogers) versions. You will f*ck up your Sprint S4. The Sprint S4 won't get LTE in Canada and will only work up to HSPA+ on non-AWS carriers. You're pretty much screwed on that model.

If you are able to complete the flash using MF3 modem and original posted method then this method should essentially give the same end result. That being said, my phone didn't function correctly with the MF3 modem and therefore the MF3 and flash file method did not suit my needs. The method I gave should be more compatible with a broader and newer range of modems and thus not leave you restricted to older modems just to keep aws. What im sharing is just my personal experience dealing with the problem.

Maybe check you band preferences ? Dial *#2263#

Is LTE Band preference set to all ? You can dial *#0011# to see what band your currently on.

check APN settings? Are your APN settings correct?

Check carrier bandwidth limitations?

I honestly don't know and possibly someone else could help a bit more on that issue. However the number that you have on line 1877 confirms that the AWS band should be unlocked.

Remember ATT SIM disables *#2263# RAT Selection menu. (Not true of other SIM's.) Easy work around is simply to remove ATT SIM and boot phone without SIM to see the menu.

I never go over my data throttling limit. If I called Tmobile support would they not help me since I am using an AT&T branded phone? I am on the $30 100 minutes plan.

I know I keep repeating myself but seems strange because it was working fine. I didn't change anything. Came back from vacation and EDGE only. Would it be worth a try to ODIN back to how the phone was when I bought it? Maybe I will go to the tmobile prepaid forum at howard and see if anyone has had this problem. Thanks again for listening and for suggestions!
[AT&T Samsung Galaxy S 4 General] kb8no:
I'm probably not well informed in this. I want to understand it better too. I wish I understood the 2263 menu better. Wish there was a "how to" Web site. I do know that if you set a particular band you get only that band. You need Automatic to get all bands. I do know that Tmo rom has more options somewhere but I don't know where. I do know you can install a Tmo rom at one time on ATT phone but it escapes me how you do that now with a locked bootloader. I heard Tmo has an unlocked bootloader. I still think your problem is somewhere in that menu

Did you try factory reset? One comment suggested that. After adding aws band on my phone with att sim I have lost signal with circle and line a few times too. Reboot phone and comes back. Can't figure out why.
[AT&T Samsung Galaxy S 4 General] ozoneaction:
I am with you on not understanding the 2263 menu. Am I always supposed to have it on automatic? But anyway I just did factory reset and still have just EDGE. Seems the factory reset did not overlay the MF3 modem that I flashed. Maybe I will try resetting via ODIN next to see what that does. If you buy an unlocked ATT and put in a Tmobile Sim like I did what kind of connection should we expect?

Hi

I have a sgh-i337 on 4.4.4 update

I am in iran. How can i active lte?
[AT&T Samsung Galaxy S 4 General] kb8no:
The ì337 is configured for North America. The LTE bands are as follows on the i337:

S4 LTE 700, 850, 1700, 1900, 2100, 2600; B17, B5, B4, B2, B1, B7

Your carrier likely does not have these LTE bands so you will not get LTE in Iran.

Happily, HSPA+ is more forgiving. With the AWS B4 modification it has the following bands:

S4 HSPA+ 850, 900, 1700, 1900, 2100; B5, B8, B4, B2, B1

Iran probably uses 2100 like Europe so you will get HSPA+ service. I was in NL and BY last August and my S4 worked great on HSPA+ but no LTE, just like you. EU (and probably Iran) uses the following LTE bands:

EU LTE 800, 1800, 2600; B18, B3, B7

To get LTE you will need the EU/Asia version of the S4. HSPA+ is robust and most of us from North America are delighted to get this when we travel.
[AT&T Samsung Galaxy S 4 General] jomhuur:
My operator say suported 1800 and 2600 on lte

Sgh-i337 not support 1800 or 2600 band?
[AT&T Samsung Galaxy S 4 General] kb8no:
Supports 2600. Not 1800. 2600 not so good propagation so your operator will prefer 1800 with good propagation. For sure they do not have 2600 everywhere. Probably 2600 in big cities only. Even you do not know for sure if any LTE in your area just because they have it somewhere.

2600 used in North America and EU/Asia and is only one used on both. Ask your provider where they use 2600. The i337 is for USA ATT and there is no 2600 here. Canada Rogers uses 2600. Most of us don't care how to use i337 on Rogers in Canada but there is a report of someone using it in Europe. If you find 2600 used in your area I have some ideas.
[AT&T Samsung Galaxy S 4 General] jomhuur:
I have 2600 band. But can not conect
[AT&T Samsung Galaxy S 4 General] Product F(RED):
2600 is for sure present. There's someone in Germany using it in this thread. 1800 and 800 aren't. Rogers uses 2600 MHz for an optional service called Rogers Max, but their main frequency is Band 4 (1700/2100 together). As stated above, unless you're in a major city where you can have mini cell towers on the tops of every building (we have those here in NYC, but we still don't use 2600 MHz), 2600 MHz is completely useless because it will barely penetrate walls at all/won't cover a big area.

Anyways, just because a carrier says "we use these 3 frequencies" does not mean they're using them all at once. From experience traveling in Europe, and also from reading most areas use 1800 MHz (which the North American models don't support). It really depends on where you are though.

Grab a friend who has a Samsung phone in your area and who is using LTE on the same network as you. Go to their Phone app and dial *#0011#* . It will tell you what frequency they're connected to. Make sure they're on LTE.
[AT&T Samsung Galaxy S 4 General] kb8no:
Ok. I don't know how much you know. What are you getting now? "4G" which is HSPD+? Go to your dialer. *#0011# What band does it say now?

Then go to *#2263# menu. Go to LTE. Go to 2600 and set this. It should force only 2600. See if you connect now. Prove it by checking *#0011#.

Remember you need to set Automatic to get HSPD+ back.

[AT&T Samsung Galaxy S 4 General] Product F(RED):

[MENTION=315372]product[/MENTION] F (RED) Thank you. Hope you approve of my advice! We don't know for sure if that guy in EU found 2600 already activated or had to play in the menu *#2263# to start it. Wonder if anyone on Rogers using i337 following this thread has ever seen 2600 or got it to work. I never saw LTE in NL on my S4 in 10 days.

[MENTION=4724599]jomhuur[/MENTION] You are on B1 2100 which is what we expect. Just because "they say" that you have 2600 doesn't mean the signal is actually at your home. Do other people get 2600 LTE at your home?

You can try to force 2600 and see if you connect.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I saw a guy in Germany using an i337 on 2600 MHz, so I know it's there. Also as far as hardware goes, the i337 and i337M are identical. It's just that Canada always has different model numbers. For example there's only one Note 3 model in Canada (all AWS enabled by default). They're the exact same as the T-Mobile model. But the Canadian model is N900W8 and the T-Mobile model is N900T.
[AT&T Samsung Galaxy S 4 General] kb8no:
Have you seen any evidence that WCDMA 900 which you see on the menu actually works?

What is the S4 equivalent sold in EU?

How do you install the Tmo ROM on the i377? I have seen reference to using it.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Not sure about 900 MHz support. It'd be great if someone could post a screenshot of the *#0011#* menu if they're using it. Though as far as I know Band 1 (2100 MHz) is more prevalent.

There are two S5 models in Europe. The i9500 is the Exynos version with no LTE. Most of Western Europe has the i9505 which has a Snapdragon 600 just like ours (but with different LTE bands).

It's hard to tell. Sometimes carriers don't list all the supported frequencies even though they're there. Sometimes carriers actually disable the frequencies. For the latter, the i337 having AWS HSPA+ disabled is the perfect example because only AT&T's competitor uses it (T-Mobile US). For the former, I've seen someone with a T-Mobile US Note 3 (which I use now) successfully connect to and use 1800 MHz in Australia.
