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.

Ok so I worked with At&t and gave them the IMEI, but still no LTE data

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.

Imgo to try this you flash via Odin?
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.

Okay... but like I said, when my Wind SIM is in, my Note 3 displays 4G.
When my sister's Rogers SIM is in, it shows 3G.
With the Wind sim, is it connected to the Wind network or is the phone roaming? Is the phone set to auto/LTE in settings? The phone is running a completely stock ROM? Phone is the sm-n900w8?

It's connected to the Wind Network... it's not roaming.
Under "Network Mode" it says:
WCDMA/GSM (auto-connect).
Wcdma/gsm appears with the wind card or Rogers card?
I've seen Samsung phones with stock firmware incorrectly displaying 4G for Wind, even though Wind's network is 3G.

Wind is 4G.
Wind mobile has HSPA+ but friends that have their service usually get 3G.

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.
Just purchased the unlocked version of the S8. I'm able to get an LTE connection just fine, but I've yet to establish a 3G connection in places that I can on the Verizon version of the S8. Has anyone on Verizon, been able to get a 3G connection on the unlocked version? To be clear, SM-G950U1 is the unlocked Snapdragon US variant, that just started shipping on 5/27, not the unlocked international exynos variant.

Also, have you tried calling into Verizon to see if they can activate anything on their end? The phone should support their CDMA.

Is there an advanced calling menu in the settings?
What happens when you go into a VZW LTE dead zone? Does it drop to 1x.
I actually try to set my phone to LTE only to conserve battery.

No, there is not. In fact, the locations of settings within the settings menus are laid out completely different. There is an advanced menu, and within that menu, the only thing phone related is an option to "identify spam," which is a replacement for Verizon's Caller ID service, only it's native to the S8 and doesn't cost anything. It appears that it's the "hiya" app, baked into the phone.
I have not had an opportunity to visit an LTE dead zone. However, in the past, when I have exited my parking garage or elevator (where I've dropped coverage) my phone's typically show a 3G connection first, and then moments later they will then show a 4G connection. With this phone, it takes longer to connect, and when it does, it connects to 4G, bypassing the 3G part of the process I described. That's what brought me here.
That said, I think I've answered my question:
According to Samsung's website the US variant of the unlocked S8 supports these bands/frequencies:
Network
Frequencies and Data Type
B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B29(700), B30(2300), B66(AWS-3)
According to Wikipedia, Verizon operates it's 2G/3G network over B0(850) and B1(1900). Of all the bands Samsung listed, I believe the Verizon ones are all LTE.
So, I guess the answer is that the unlocked S8 does not support Verizon's 2G/3G network, and I better hope that I don't end up in an area where Verizon only offers 3G. HTC's new U11 is the same way.

Direct from Samsung. I haven't, but my understanding is that you're on your own when it comes to unlocked devices. I don't think it does support CDMA, now that I've researched it more. See prior post explaining why.

I've seen your explanation, and it's very logical. The only problem is it directly contradicts what the back of a 955U1 box says - "Wireless voice, data, and messaging services compatible with most major U.S. GSM and CDMA networks." It also contradicts how Samsung did the S7/S7 Edge, being compatible with all four networks in the U.S.
Again, I'm not saying your wrong, but given that the G955U is the model used on all U.S. carriers and has full band compatibility, it just doesn't make sense that Samsung would do this. And yes, I know, Samsung doesn't have to make sense...

The band types you listed are only for LTE. Band numbers for GSM, And CDMA are different.
Try the dialer codes to see what RF bands are enabled. Dial *#2263# in the phone dialer to get the menu. Dialing *#0011# will give you current status of Cell radio.
I'm certain the phone has the required radios and antenna to support all Carrier network cell types but whether it's enabled is another story.

Do those dialer codes work for you? I can't get them to work on neither the Verizon SM-G950U nor the unlocked U1 that I have.
And yes, that's what my advanced calling menu on my Verizon S8 looks like as well. The unlocked version doesn't have that. Only an option to turn on VoLTE. No Video nor WiFi calling. Also, there's no visual voicemail, which sucks.
The codes do not work for me on my VZW phone., but works on my TMO phone.
I'm wondering if it's SIM dependent.

I was able to test another unlocked version today, and it had no problems connecting to Verizon 3G, so I guess I just have a bad device. If anyone else runs into this issue, exchange it.

I recently bought an S7 edge unlocked SM-G935F Exynos version. I am currently using it on T-Mobile and have VoLTE and WiFi calling after flashing the TMobile CSC. However, I cannot get the right bands working for Carrier Aggregation. When I go into ServiceMode, the only CA combinations showing are :
7C(A)
7A-7A(A-n)
There's nothing about bands 2, 4, or 12 that T-Mobile uses. I've tried using various ROMs and CSC tools to try to get the correct bands for CA to show up but nothing. Does anyone have any insight on how to get this enabled? I saw something a year old on reddit but the details were a little vague.

Tried what was mentioned in that article. It didn't work. No idea why the CA is also only showing Band 7 when T-Mobile only uses 2,4,12.
What's even more strange... I brought the phone overseas to Taiwan last week, popped in a Chunghwa Telecom SIM, and all CA band combos for LTE bands 3,7,8,28 showed up without any issues and the phone was lightning fast.

Check with another US SIM card and see if the T-Mobile card's behavior or the Taiwanese one is replicated.
Try with a Metro, Cricket or AT&T card.
Also, on which network was this phone previously used? Because I am not sure if I'm right but if it was used with a CDMA network, it might not work with GSM US networks (not sure about it tho).

I know the previous owner on Swappa said that he used the phone with Cricket, but no clue if he checked if CA was working. Also I thought the Exynos varieties didn’t have any support for CDMA.

Does anybody use the exynos varient on AT&T or T-Mobile? I'm wondering if you get good service. I'm currently using an exynos S8+ on AT&T without any problems.
i had s9 duos exynos on att. excellent reception. im located in Boston.
Download speedtest to check your data/wifi speed
Thank you for the information. I looked up the S9 exinos on frequencycheck.com. It supports 3 out of the 4 4g bands on AT&T. According to the website the s10 exynos only supports 2 out of 4. So that doesn't help too much but I never thought about checking the s9 since I know it works well.
Works great for me. I got an Exynos from Australia when my phone died. Checked the bands for SM-G975F, and it has all the T-Mobile LTE bands EXCEPT band 71. So you will be good unless you go into rural USA.
Only thing I don't get is Carrier Aggregation. I have wifi calling and VOLTE..
Thank you for the info. After looking up that model it should work fine on both networks. That website I was using has wrong info on some of the models. I think I will buy the SM-G975F.

I also have the G975 F(BTU - United Kingdom) I live in Milwaukee on ATT Network. I get great LTE Speeds - the only thing I don't get is Wifi Calling and ATT Video Calling - ATT only supports their phones for those features - at least until there is a custom CSC that we can flash (like someone did for the Note 9, S8Plus, etc)
Do you have VoLTE at least on AT&T with the exynos?

Thank you for the info. I want to keep AT&T but I would switch to T-Mobile to get the exynos variant if needed. But I'm glad I can keep my service. I had the original IPhone and I'm grandfathered in to the original unlimited data plan. I didn't even know AT&T offered wifi calling. Before my exynos s8+ I had a note 4 and for about a year my moms extra free IPhone 6. It wasn't an option back then. I don't really care about WiFi calling though. I get good service where it matters most. I can't wait for S10+ Roms!

I get limited carrier aggregation on my Exynos S10+ on T-mobile which helps a little. It still lacks the full CA support tho.

How do you check that? I check on my service menu and it says CA:None
I do see that I am sometimes connected to three of the same band at the same time.

First you download a file or run speed test using speed test app, then at the same time dial *#0011# and select SIM slot it'll say CA added or CA active. This means you're getting some form of aggregation

That's what I've been doing, but I don't see CA added or active. I wonder why mine doesn't even have CA on. Just CA none.

And you have the Exynos version correct? Try it in a different area away from your home and see if it activates. If nothing works, factory reset may help.

I am on Exynos, wouldn't have this problem with the SD version (I'd hope). I have factory reset a few times, but never see the CA as activated. I'll check from time to time, but also away from my house it doesn't show that CA is activated. Might be the XSF (australian) version that doesn't aggregate the t-mobile bands.

That could be it. I'm using TPA CSC and some other people on that CSC confirmed carrier aggregation working on T-mobile.
Snapdragon (Chinese or Hong Kong variant) does not support carrier aggregation in T-mobile from what a user posted.

Do you have a link to the post where it is CA is confirmed on TMO?
For which model the Chinese Snapdragon?
CA is working for me on Exynos. It is not the same as US Snapdragon CA but still better than no CA at all

Do you need to flash a CSC and/or modem from a US carrier onto an exynos international phone to get VoWIFI, CA, VoLTE, etc? Or does it "just work?" If you need a special CSC do you just pull HOME_CSC out of a US carrier's firmware and flash it with odin or something?

Hi
You should not flash any firmware from a Snapdragon into a Exynos..... You may not be able to get some of the service provider options using the Exynos firmware, i guess is a try and see situation, but one thing is for sure do not flash a Snapdragon firmware into an Exynos.
Everything else should work , modem is ready for all frequencies but CDMA
in case anyone comes looking, i've tried it on an exynos G973F with XSG csc (one of the OXM multi ones) just because that's what was on the phone.
VoLTE seems to be working on T-Mobile in the US without any messing around, based on the "HD" icon appearing during voice calls. Voice over WiFi seems to also work.
The phone is dual SIM with a TMO sim and an ATT sim. It doesn't get VoLTE on ATT, but I believe that's probably because AT&T only allows it on approved devices.
