Who is using the 910C/F on AT&T

IS anyone actually using he 910F/C on AT&T and getting LTE speeds? I see a lot of theory and band matching but I am not sure band numbers are the end all in different countries. Before I pay $800 for a US version I want to be sure I HAVE to in order to get LTE Speeds on an unlocked device

I'm using N910C on AT&T. LTE works, at least where I'm at (Ohio). It works out of the box for me while others say they have to call AT&T to have them provision your account with new IMEI.

Anyone else using this phone on att? All of the negative reviews on amazon are people claiming that they dont get lte with this version.

Using 910c and getting lte

Decided to go with T Mobile Note 4, Easier to sell if it does not work with LTE.

Just ordered an N910C, and plan on using it on AT&T. I live in Missouri, and will report how it does. All of the bands are there. So I don't see why it wouldn't.

What did you find out? I'm trying to decide which model to get also LTE in AT&T Los Angeles, specifically if N910U will work.

So I have had it for a couple weeks. At first I was disappointed to learn that I did not have LTE. My download speed seemed low, the icon only showed 4G, and "LTE Discovery" showed LTE, but no band. I spent a couple hours on the phone with AT&T troubleshooting, went to a corporate store to get a new sim, and nothing worked.
HOWEVER, I put my phone into service mode at my house. You enter service mode by entering "*#0011#" into your phone dialer. Once in here, it said that I was connected to LTE band 17. So I went to another city praying that band 4 would be there, because then both LTE bands would be confirmed. Boom band 4 shows up in service mode, too.
So after quite a while of testing, I can confirm LTE connectivity for AT&T on the N910C for both band 17 and 4. I also learned that I was speed testing during prime time hours. So my tower was congested, and that was why the speeds were low. The icon didn't show, because there doesn't seem to be an LTE icon in the system.
On the topic of the N910U, though, I was pretty sure that it was a 3G only device. I may be wrong, and will look into it.
UPDATE: From what I have found, the N910U supports the following bands: 1,2,3,4,5,7,8,28. AT&T uses 4 and 17. So the device only has 1 of 2 LTE bands. So theoretically, you could connect to LTE in a band 4 area, but I also found some reports on XDA of AT&T's towers only handing down HSPA+ even in those areas. You can join that discussion HERE. Hope this helps.

4G LTE Confirmed Working AT&T

Got this up and running after some delays.
Basically just use the APN settings from their site...
http://www.att.com/esupport/article.jsp?sid=KB424489&cv=820
When using the IMEI that shipped with the phone it put it under a basic phone plan.. (No VVM, no LTE). What I did was just use the IMEI from my old Galaxy S3 and 4G kicked on.
THIS WILL NOT SHOW LTE IN THE BAR BUT RATHER AS SIMPLY 4G.
CHEERS!:good::good::good:

Download lte discovery and see what band you are using please. Mine gets it on band 2 (1900) but that is it.

Band 2 is what it is here as well... Luckily i live in a place that has it.

4G LTE 2600(7) Not Working
Last week I went to Taiwan and get a ZenFone 2 (ZE551ML) 2GB, the firmware for Taiwan doesn't support this band, I downloaded the latest WW firmware, but no luck, any Idea?

So weird, it seems to have worked. Even though the settings are identical to what I had initially.

Losing hope here in Tucson AZ. All I can manage is a measly "H+" symbol and my speeds are a spotty 4mb down to .500 mb speeds... Is there any way to check what frequency the towers are in my area? I suspect we in the old pueblo only have the older ATT speeds for the frequency supported. (SIGH)

AT&T is a pain to get working with it. At first, I popped in my Sim card straight from my Note 4, no luck. So I called AT&T and added the IMEI. Still no luck and found out they reprovisioned my SIM card for HSPA+ only. I popped my SIM back into my Note 4, it only showed 4G/HSPA+ and not LTE. Called AT&T to have them swap the IMEI back to the Note 4 and got LTE on my Note 4 Then swapped the SIM back into the ZF2 and I got 4G (LTE).

ATT boggles the mind. I use an MVNO w/ ATT (Net10/Tracphone) and I never have this problem. Wonder why the resellers are less hassle?

I have an old straight talk SIM on ATT with APN of att.mvno and I don't see any LTE. Will try a genuine AT&T SIM tomorrow and see what happens. I'm really not looking forward to moving my number to a tfdata ST SIM.

Correct. I now have a Zenfone 2 US version. My old ST SIM that used att.mvno still had zero LTE. I moved to a new ST SIM that uses tfdata and I now have LTE on band 17.

Any thoughts on how to get activated and working LTE working on my ZE511ML as a new customer with no previous GSM IMEI? I may be able to get a SIM from someone else but it doesn't sound like that's enough.

I had this problem with AT&T as well. AT&T will drop you to HSPA once you register your ZF2's IMEI with a new SIM cos their system doesn't recognize our ZF2 (or any unlocked device that they themselves do not sell) as an LTE device.
I went to the nearest AT&T store and got it sorted by telling the rep to delete my ZF2's IMEI and give me a new SIM.
If you're signing up for new service with them, tell them you don't have the phone with you and to just give you a micro SIM.

I just got my ZF2 today and tried my ST SIM it shows 4G. I was wondering what speed you guys getting in 4G AT&T I am in Northern KY area on band 17

MY ST sim in Iowa shows 4G and uses lte band 4 ( according to LTE Discovery ). Speedtest shows: 124ms, 17.3 Mbps down, 7.36 Mbps up.

So any workarounds with this? I have LTE and I'm picking up band 17, but only getting 4Mbps down. I like this phone a lot, but if I can't get LTE speeds it is basically useless.

I got 4 ZF2's and all of them work with LTE At&T. All I did was call a rep and told her the APN that she was giving me (nxtgenphone) was nto going to work for my phone and that I needed her to force the LTE plan. She forwarded that to an IT rep and everything worked. They will need your IMEI numbers to set it up.

What speeds are you getting? Because mine clearly connects to LTE, but the speeds are basically 3G.

Mine says 4G, doesn't LTE like my S5 but it faster than my S5 when on the net.

[Q] N910H on straight talk with ATT sim only getting edge

So I bought my wife what I thought was a good deal and got her the N910H not knowing that it was 3G only. Ok, well, on her verizon branded unlocked note 2 she can get HSPA speeds with her sim, but with the note 4 that's unlocked, she hasn't seen above the edge network, and her signal is garbage. APN settings are what they should be, tried a few different variations, and nothing. Bought a Verizon 4G LTE sim from straight talk for her, before I realized it was 3G only and only assumed it would help. But would it help? Both ATT and Verizon get LTE coverage in the area, or what can I do to fix my signal? Oh yeah, and I can't send or receive pictures...ugh. HELP
*apparently she can now receive pictures, but still can't send them

Try changing the modem, i should help, cheers:fingers-crossed:

I almost purchased the 910H myself but luckily found out it doesn't support LTE before pulling the trigger. If you can still return it, get the 910C model instead. It supports LTE for both AT&T & T-Mobile.
I'm using my 910C on Straight Talk AT&T ATM.

So, just tried the only 2 other modems I could find for my N910H running KitKat, and signal is no different. Any more ideas?

update
Ok, so playing around with some of the settings in more networks, mobile networks I changed the network mode from gsm only to wcdma/gsm (auto connect) and data speeds are NOW where they should be, which is 3G, and with a full signal got 8MB down speed, so, that's good. Now the question becomes why can i receive pictures and not send them. Actually managed to get a couple to go through, but no clue how or why they went through.

G935FD duos (dual SIM) - no LTE on T-Mobile in the US

My S7 Edge G935FD (dual SIM international version) gets only "4G" on T-Mobile in the San Francisco Bay Area, and never "LTE". Is this a "4G vs. LTE" naming issue, or does it lack the band T-Mobile requires for LTE? It also gets "H+" often, in the same location that my old S5 had full bars LTE.
Speed tests with the SpeedSpot app range from 17Mbps to 33Mbps down, and 3.75 to 7.5Mbps up on "4G", but only 5Mbps down and 1Mbps up in H+ areas.
I bought it from tropical_mobile on eBay.

I think 4g and lte are the same..

Just naming issue with international version.

@kvsandeepreddy is right.
LTE means LongTermEvolution which is the so called 4th generation of Mobile Networks. So LTE is 4G
1G = Analog mobile Network, I think
2G = GSM and EDGE
3G = UMTS and HSDPA
4G = LTE

FD version is released for asian countries... back in india we use 4g instead of lte

Poorer connectivity on S7 than S5

Well, that means that the S7 dual-SIM gets poorer reception than my old single-SIM S5:
In the same spot in the building (at my work desk), I'd get full LTE bars on the old S5, but only H or H+ at best on the new S7 Edge dual SIM. In practice this means ~6x slower downloads and ~7x slower uploads. Pretty ****ty.

Phone being a dual sim doesnt usually affect the sig al strength.. maybe the inbuilt receiver in s7 edge is defective.. heard some other people complaining about the signal strength too

No that's not what it means. The g935fd version is meant to be able to switch to any international firmware version. There are several different modems for each region. You are going to just have to flash different modems in Odin and see which one works best for your region. This does not trip knox or void warranty as long as you do it right because you are flashing official modems. As I said in the other thread you were in, do your research.

Can someone link me to the best modem to used on the dual sim model in the states?

Which modem did you end up using? I am also wondering which version is best in the US.

I'm just using the UAE firmware that the duos came with. It's updated with the June security patch. Only issue I've had is slower than normal download and upload speeds on at&t. It's not that big of a deal, just annoying. I think it has more to do with atts provisioning on their network. I'll post a solution if I figure it out, whether it's a different csc, apn settings or some device setting on my account.

4G is called LTE in USA. If you are getting 4G. That means you are getting LTE.

Yes, you are correct. However, I should have clarified that my statement is based on connection speed tests not on network symbols in notification bar. My slower speeds are in comparison to other 4g devices being tested in the same location on the same network.

Yep. I can confirm the same thing. I have 2 s7 edges. One is a DUOS and the other is AT&T branded. Tested both repeatedly and found that the AT&T branded device is getting way faster speeds than the DUOS. In my particular area the AT&T phone was reaching up to 60 Mbps while the DUOS was only hitting 30-40 Mbps. Very curious on how to fix this since this phone has all the necessary bands to support LTE in the states.

At least you're getting that. My speed tests are consistently in the .72 to 5 Mbps range on the DL and 1-7Mbps on the upload, which is basically about half to a third of what my other AT&T devices are getting in the same location at same time.

Wow your right that is abysmal. Have you tried installing LTE Discovery and comparing the two devices? Check to see if they are connecting to the same towers.

It's not just the bands. AT&T is known for prioritizing their branded phones vs. BYOD phones. It's done by EMEI ... they have a list of all their branded models in a DB and they get priority. TMO doesn't much care. I tested my Duos yesterday and TMO gave me 59.4/12.8 network transfer. It's as good as my 6P. My AT&T sim is in sim1 and is restricted to 2G which is fine since I need calls and texts only from it since it's a work #.
And it does support most of AT&T's bands except band30 which is really new. 4G everywhere else is LTE here as was said in other responses in this thread. It's most likely AT&T deprioritizing the phone as it's a BYOD.

It doesn't have band 12 so I'd save your money. Band 12 is just the deeper penetration 700mhz anyway which around me (SF area) can't be found. My Nexus 6P which has band 12 never connects to anything but band 4 .. ever.

I noticed this as well with my 6p. Supposedly band 12 was to save us all but my phone prefers band 4. I only got a glimpse of band 12 the other day then the phone switch switched back to band 4 when I toggled wifi on and off.

Verizon Signal Strength/reliability

Hey all,
I've seen a few posts regarding signal problems on TMO and Sprint, but not much on Verizon.
How is your guys' experience on VZW?

Works good for me on Verizon. I don't live in a big city, but I never lose service and I get over 100mbs dowload speeds in certain areas over LTE.

Been using mine on Verizon for a week now and no issues so far. It works everywhere any other device i have used works.

PH-1 reception in my house in mid-peninsula SF Bay Area is non-existent. Meanwhile the Galaxy 7, Galaxy 5, iPhone 5, and iPhone 7 all get decent enough signal here. No matter how good the phone otherwise, that's a deal killer.
Update: the phone continues to frustrate. Reception sucks even in the heart of towns here where other phones are just fine. Basically, the phone is useless except as a pretty iPod that takes cool 360 pictures. What a shame.

What's a good app to test download speeds?

I live in upstate NY. Literally in a gorge.i get the same or better service than my HTC 10 and the WiFi is way better. Don't need WiFi calling anymore.

I'm also in upstate NY. I get extremely fast speeds on wifi but lte seems pretty slow. What network settings are you all using??

Ref: Verizon
I'm getting LTE+ carrier aggregation in the Hickory, NC area. I've seen download speeds as high as 28 Mbps, although I've only been on Verizon 2 days now and I've only ran a few speed tests.
I recently ported my number to Verizon from T-Mobile because I was one of those who was experiencing connectivity issues with T-Mo. For me this phone works much better on Verizon than T-Mo. The phone I have now is a replacement. The first one constantly dropped cellular connections and with it I never saw LTE+ on T-Mo not even once. With the new replacement phone it showed up at times closer to Hickory but Verizon seems to have it everywhere around here.

That's funny actually, right after I took that, I went to lte discovery app, and saw that I was on band 4 & 13 . It's not " supposed " to work...lol

I'm using Xfinity which is Verizon and works fine on the SF Bay Area but since I'm using Xfinity and not Verizon proper, I don't see the option for enhanced LTE...

That's good. We don't have those kind of speeds around here. 28-34 is normal for Verizon lte here.

My download speeds are only averaging 7 mbps on lte on Verizon in NY.
Which bands are you all using?? I left mine on the default and not sure if that'd make a difference.
I tried a few others with not much difference

This is my 3rd replacement. The first one didn't activate, the second overheated and now the 3rd seems to be working well. What I noticed on the 3rd one after reading the forums is the ceramic I'd alittle grippier than the last one which was smooth like glass. The 2nd one was smooth like glass. Before I did the replacement I also weighed it by hand because I read somewhere the new replacements have alittle more weight to it and it did. It was noticeable.
As far as signal. It seems to be on par with my m9. I was surprised I got 117mbps in my town which is in Shentel territory for Sprint but so far everything works great

Hit and Miss
Mine has been iffy since I "officially" added it to my Verizon account (I initially just pulled the SIM from my Pixel, and plopped it in my Essential - Worked like a champ, then I replaced my Pixel with my Essential with customer service, over the phone, and after reboot, it has been hit or miss (it was 3G from the time I hung up with Verizon, until I finished driving from Vegas to SLC). I messed with the carrier settings, and it was LTE+ for a day, then back to no signal the next morning.
Some days 3G is the best I can get, others LTE+ works fine, and some days, 1X or no signal. I've tried changing the settings from Global, to LTE, to LTE/WCDMA to what ever else looked okay). Today, it's been LTE+ most of the day.
