I just bought the 935F and I am stuck on Edge data. I also have the At&t model of the gs7 edge and I get full LTE and good speeds in the exact same spot. Same sim card, and I believe I'm using the correct APN settings. I want to switch to the international model because at&t ruins this phone with bloatware. I get a lot of lag on the at&t gs7 edge, and no lag at all on the 935F. Now I just need the LTE to work!!
Anyone able to try and help? I did search the forum first and didnt see anything relevant.
do you see 4G instead but not LTE on your 935F? US carriers call HSPA+ 4G (while it's 3G+) so when their branded phones are in LTE they add an LTE (or 4G LTE for tmobile) icon. My G935F always shows 4G but it's actually LTE. You can dial *#0011# to check for reception or download the LTE discovery app to check your reception

Thank you very much for the reply. I see E for edge data. I think I may have made some progress by changing the APN settings though. I am seeing LTE now, but the speeds are terrible. Nothing close to what I was getting with the ATT branded version of the GS7E.
Anyone know exactly what APN settings the G935F should be using on ATT? I have unlimited data, so I want to be able to use it!

It has nothing to do with the APN, but you have to tell AT&T you have an AT&T branded phone and give them an imei of that phone. Or your 935F will not be able to get lte.

Hmm, Ok thank you. I'll try that now. I haven't been on att in years, and don't remember having to do that but I will now.
Yeah if you don't have an ATT branded phone they will limit you to the 4g network and not the new LTE network. I bought a cheap Motorola LTe phone that was an at&t approved. I gave them its imei, and I started to get lte.

No, you do not have to give AT&T the IMEI of your 935F phone.
I just got back to the US, popped my AT&T SIM card in my new intl S7e (935FD) and LTE works as it should. I get speeds of >10 Mbs
LTE bands 2 & 17 are used (in my area - Portland)
Not getting full speed LTE
I have the 935FD S7E. I just went to the AT&T store as I needed a nano sim. The guy who helped me did a Speed Test right next to me performing the exact same test. His AT&T S7 was receiving in the mid to high 30's for download speed while I was getting in the mid 20's. He checked the APN, we assumed that I was getting an LTE speed even though no LTE icon showed. However his S7 was receiving significantly consistent faster data rates than I was getting.
Is there anything I can do to resolve this?
This will be the main hindrance for me buying the international version. If someone gets the LTE thing figured out I'm all in

For what it's worth, AT&T LTE problems in my case were caused by custom ROM.
I just got International S7 Edge (G935F), and without thinking, rooted it and installed SuperMan-ROM 1.8.1. In that state I did have LTE formally, but speeds were very bad. Tried turning data on/off, changing APNs - nothing helped. As a result, in some places data connection barely worked (1.0 Mbps down / 0.1 Mbps up), and the best result reported by SpeedTest was around 4 Mbps up/down. At the same time, when I moved this SIM card into older XPeria phone, it consistently showed ~15 Mbps up/down, which was normal performance for me on AT&T prepaid in NYC. Unfortunately, I didn't check LTE performance with the original default ROM on the Edge, but I recorded all versions.
I went back to stock ROM using this German stock firmware. It was possible to switch to English during installation. Other downloads in that thread are dead links. I immediately did official OTA update, and after that, I now have normal LTE performance on AT&T (15+ Mbps).
I am pretty sure that at least in my case, the radio which the custom ROM insisted I have (G935FXXU1APEQ) was the problem. After going back to stock, I have baseband G935FXXU1APD1, which is what I had out-of-the-box.

It's showing the same bands to it should work, no one will know until they actually test it. The Note 3 also had the same bands, but some anecdotal reports stated the reception was a bit worse and it didn't hang onto LTE as well. Nothing scientific, just users reporting this so make of it what you will. Personally my business can't take the chance of reception issues so I just bit the bullet and got the ATT version knowing I am saying goodbye to root. Once again this is unsubstantiated, it's just what I got from hours of looking at all the forum posts about using the Tmo Note 3 on ATT.
How about a Verizon Note 4 on AT&T? Verizon is charging almost $150 less for an off contract phone, however I have a mobile share plan with other AT&T phones on contract so I'd need to stay on AT&T if possible...
Is it possible to "unlock" (or whatever the term is) an AT&T phone to use with Tmobile?

Yes you can and the term is "unlock". Just make sure the bands are compatible on your at&t phone with the Tmobile network.

I know you can use TMOBILE PHONES on ATT - I assume you can do the reverse -but I don't think you can run TMOBILE PHONES on Verizon - or Verizon PHones on TMOBILE - I say this because the roms created for Verizon were really never very compatible for Tmobile phones ( at least not for me on any of the roms I tried to flash - data didn't work - wifi didn't work - ) so I htink they have different kinds of radios - but I am not a developer so that is only a guess -

Yes - as long as you manually add the APNS - but keep in mind the ATT PHONE will have a locked bootloader and it will probably be a while until someone finds a way to root the ATT PHONE - I say this based on what happened with the Note3 and S5 - I assume the same will be the case for ATT NOte 4s
If somebody takes an AT&T phone to T-Mobile, it will get fully functional LTE (as they both use band 4 aws). However, T-Mobile has built most of its 3G network on Band 4 UMTS / HSPA (AWS 1700/2100) which AT&T phones to not support. This coverage footprint is bigger than their current LTE network. The AT&T phone will get Band 2 (1900) UMTS / HSPA in the areas T-Mobile has refarmed.
A T-Mobile phone is fully compatible with AT&T. All T-Mobile phones support bands 2 and 5 for 3G (H+). T-Mobile phones also support AT&T's Band 17 for roaming reasons.
Be advised that if your using a T-Mobile device on AT&T (preferably an LTE device) it may not get the best reception, as AT&T optimizes their modems for their lower frequencies. Last year my T-Mobile Note 3 LTE reception was awful on AT&T. The T-Mobile S5 on AT&T was improved, but not as good as AT&T's own S5's reception.

I'm not sure. But a few years ago there was a guy from Canada using a Rogers device ( I think the S3?) anyway AT&T had just released an update for their S3 and it drastically improved signal strength and data speeds. He took it upon himself to flash only the modem from CWM. The phone rebooted and he had no IMEI number. Therefore his phone couldn't even connect to the network. I'm not sure how or if he resolved it. But that lesson right there made me never flash any carrier's modem on my device.

What band is being used when you connect to LTE?
Dial *#0011# when you're on LTE and click STACK 1 if it's in the first SIM slot, and STACK 2 if it's in the second one.
It'll show you Band information.
Secondly, it could also be because of the carrier aggregation stuff, maybe the Exynos variant of the S7E isn't compatible with T-Mobile's Carrier Aggregated LTE network and hence only uses one band for LTE, which will result in poor speeds for the user.
Has anyone experienced bad or inconsistent LTE speeds on the International S7 Edge Duos while on AT&T? I was out walking the dog yesterday and my speeds were ranging anywhere from 0.3 megabits/second to 12 megabits/second depending on which block I am on. This morning, on my commute to work, I had anywhere from 2 megabits/second speeds or 32 megabits/second speeds depending on where I am on the road.
Is the International not nearly as good with using AT&T band LTE? Is there perhaps an APN setting I should be making? Or should I just learn to live with this?
Thanks in advance
No one has encountered this at all? Perhaps it's emblematic of a potential defect?
Im on att using g935fd, no issue with lte. Im ranging from 15-30 mbps depending on the area. im in boston,ma
in dallas with a 935FD and i've been getting average 29mb down/19mb up... check your APN and also consider testing with another sim card if you have one available.
I'm having the same issue. There is definitely something going on with the Duos. I'm on T-mobile and experience weaker signal (10-15 dBm) on Duos than I get on my 935T sitting next to it. I've flashed several modems, csc's and firmwares. Nothing has helped. Even lost signal last week at a clinic and had to tether of my wife's T-Mobile s7 edge.

It got so bad that I am returning the phone. The speeds I was getting was just too low to make it a useful device.
Maybe its the rom. What firmware you guys are using? I flashed the stock g935f PHN firmware, CSC, AP and then OntheedgeLite UX rom.
There was another posst with OP having similar issue. I have issue as well. But flashing BTU csc ap bl and cp helped me gain better 4g around my home, so I thought problem was fixed. but when I go to poor reception areas and phone is switching to 2g/3g bands, I lose 4g unless restart or messing with sim options switching 4g between sim1 and sim 2.
currently on stock samsung touchwiz rom. BTU cp, csc, ap, and bl
Is it missing the appropriate at&t bands ? I'm looking at note duos as an alternative to the ATT version a day it's meant to be the same chipset and that misses one of the LTE bands.

I have a Samsung Note 3 that I bought from Mobilicity (Canada).
It is unlocked.
When I put my Wind Mobility SIM card in, the data says 4G.
I want to give the phone to my sister, who broke hers, but she is with Rogers.
I put her Rogers SIM in my phone and everything works great.
But, I don't understand why the phone says 3G with her Rogers SIM in it.
Does anyone know why? I was under the impression that Rogers is faster than Wind's data. So how can Wind be 4G but Rogers 3G.
Both carriers have the same model number of the Note 3.
Wind has 4g? Maybe the Rogers card is not an LTE sim?
Could be any number of reasons:
- The provider isn't enabled for 4G in the Build.prop.
- The SIM is too old.
- The SIM doesn't support LTE
Probably the first. The list of 4G enabled providers rarely makes sense. It is literally just a matter of 'true' or 'false'.
We had a similar issue in the EU with various firmwares when 4G became available, every CSC has its own list of 4G enabled providers. For instance, DBT (Germany) had 4G enabled for T-Mobile NL, while the T-Mobile NL firmware didn't have 4G enabled for itself.

Hmm... I'll ask my sister to check her SIM card. But I doubt they would have given her the wrong "new" SIM card that she just got.
If the Rogers sim card is new, it would be a LTE-enabled card so that can't be it. Also, Wind only has a 3g network.

It's connected to the Wind Network... it's not roaming.
Under "Network Mode" it says:

Okay thanks for this comment above. It was helpful because it got me searching for more along that line.
When I went into the settings, there was no option to choose LTE, but I know it's an LTE capable phone because the box said it was, and the sticker on the phone said 4G/LTE.
So I did some searching and found that there is a code that you have to use to set the phone to the Network you are using if you want to make use of the LTE.
Rogers has LTE.
I will go into a Rogers and ask them to do it, because I don't want to ruin my sister's phone (my phone that I gave to her, because her's broke).
It's *2012# (IMEI)* Something like that. I have it written down, so I'll bring it to the Rogers store and ask them.
Hopefully that will get her phone working on Rogers LTE, but in the meantime, she hasn't noticed a difference in data speed anyway.
But thanks for your help, and also to everyone else who posted a reply. :victory:
Have a similar thing going on with EE.
Supposed to choose 4g if available but it's not always the case.
Sometimes shows 3g or H+ but if I change my network mode to LTE only then I get 4g no problem.

I don't have the phone anymore. My sister has it, so I can't check. She's technically challenged, so I wouldn't even be able to get that info from her on the phone. Lol
But I will see if I need to turn on the other bands by using that code to set it to Rogers' service.
Hey everyone,
I read for hours but unfortunately I haven't been able to find the solution.
So I bought a Galaxy S4 GT-I9515 in Europe and I'm not able to get any speeds higher than 2g on my USA 4g T-mobile plan.
The network mode is set on auto connect (LTE/WCDMA/GSM). I tried setting up a t-mobile 4g APN but it won't accept it (it pops back to standard after a few seconds..)
The simcard does work at 4g on another phone.
I rooted it with chainfire autoroot but this made no difference.
Anyone have a clue? At least 3g would be nice and should be possible..
Does the gt-9515 support the carrier's 3g and 4g frequencies?
Hey, thanks for thinking along..
According to frequencycheck.com, yes (both 3g and 4g).
Also, the t-mobile store didn't make notice of this being a problem. They were horribly incompetent though (just googling everything..) But you'd think they would at least check that much.
The I9515 won't get LTE in Europe as bands 2, 4, 12, and 17 aren't used there. The best you can do is HSPA (3.5G in the US) for data. If you're not getting at least HSPA the local carrier may have throttled you.

If I put the simcard in my old phone (moto G 1st gen) it makes an LTE connection so I'm not throttled.
I downloaded an app called LTE Discovery which doesn't read an LTE connection but says HSPA: -75.0 dBm is available.
With an internet speed test I'm only getting 770 Kbps however.
Oh, and I'm in Las Vegas currently (not in the middle of nowhere before anyone asks.. )
It's about the same speed in the Bay-area.
I misread your initial post. The fact you're not picking up LTE in Las Vegas means something else is wrong. In fact it makes me wonder if you even have an I9515. Kindly enter download mode and read off the model number please?
If things are as I suspect they are, then you're actually in possession of an I9505. My comments in my earlier post regarding LTE still apply, except it's the phone lacking the US bands instead of lacking European bands.

You're right, I mentioned the US T-mobile plan but forgot to clearly mention where the problem was occurring/where I want to use the phone (which I bought in the Netherlands). Just to be clear: I am in the USA and that's where I intend to use it.
ODIN MODE
Product Name: GT-I9515
Ok...I'm really confusing myself. For some odd reason I had the Straight Talk S4 in mind. LOL.
The I9505 and I9515 have the same bands: 1, 3, 5, 7, 8, and 20. You won't get LTE in the US on this device and are limited to HSPA here. Fortunately, HSPA is fast enough for multimedia, so unless T-Mobile is repurposing its 3G network for LTE you should see about 4 or 5Mb a second.
Thanks for analyzing, you seem to know a lot about this.
However, the primary problem is I'm not reaching any HSPA speeds either.
I know a lot about this, as I have an I9505 and live in the US.
The phone is working properly, so speed issues are carrier related. And it's not uncommon. I've had it happen myself, on AT&T towers.
