They don't.

Correct. Your IMEI is published and easily looked up by just about anyone.

[Samsung Galaxy Nexus] ruffneckc:
I haven't messed with my APN but the speeds are pretty spectacular when transmitting and the "H" is displayed. It's definitely faster than 3G speeds and I'm happy with it as it is for now.
[Samsung Galaxy Nexus] Gary86:
Thanks...so everyone can confirm these settings are good? I'm already on a smartphone plan if that matters.
[Samsung Galaxy Nexus] BarryH_GEG:
They do. If you look at any of the prior Nexi forums you'll see it discussed. The IMEI's provided by Google are are associated to the phone's model number. That's why Nexi can't use AT&T non-Smartphone data plans while other international phones can. Google started doing this to make nice with the carriers after their direct distribution attempt with the G1 bombed.

But there's no association to a specific model of phone. The link you posted just discusses how IMEI's are assigned and managed. AT&T having the IMEI of a phone doesn't allow them to know the make and model of the phone. All the phones they sell are IMEI/model associated.
[Samsung Galaxy Nexus] ranphi:
I'm also using an imported Galaxy Nexus on AT&T. I've tried using both the "Cingular 410" APN that the phone registered automatically after popping in my SIM and the "Phone" APN after manually creating it. I've noticed with both of those APNs that most of the time the "3G" icon appears in the Notification Bar until I actively start using an app/do something on the phone that requires data usage and then the "H" icon usually appears and stays there while data is transmitting up/down. Once the data flow stops, it goes back to the "3G" icon.

My data speeds for both download and upload seem to be on par with what I'm used to getting from AT&T where I live, FWIW.

I've never seen this behavior before on any of the many phones I've used with AT&T over several years, so I'm just curious if this is the norm with the Galaxy Nexus or not. Have any of you fellow AT&T Galaxy Nexus users noticed this behavior on your own phone?

Thanks! :)
[Samsung Galaxy Nexus] oscillik:
Yes this is normal. Getting the same over here in the UK.
[Samsung Galaxy Nexus] zevrosenthal:
My new SGN (upgraded from SGS2 that I also bought internationally) is giving roughly the same speeds with the default "Cingular 410" as with the AT&T US HSPDA APN settings. My SGS2 was on a "4G" plan and it seems my SGN had no problems being recognized by AT&T servers. I'm on a tethering plan and it validated the tethering without any problems.

Thanks for the details on the correct APN settings - this is the most succinct and accurate listing I've found to date.
[Samsung Galaxy Nexus] ranphi:
Interesting...wonder why they apparently implemented it in this fashion. Oh well, not a big deal. I do find it a bit curious, though.

Thanks for the confirmation, oscillik! Appreciate it. :)
[Samsung Galaxy Nexus] milan03:
AFAIK With international unlocked GN you don't even have to have a tethering plan to tether on either AT&T nor T-Mobile. It should work out of the box and there isn't a red flag of any kind raised in their systems other than large amount of data used.
[Samsung Galaxy Nexus] BarryH_GEG:
Power saving. It idles at 2G/3G and HSPA+ kicks in when needed. Kind of like stop/start technology being introduced on cars.
[Samsung Galaxy Nexus] ianwood:
The confidence with which some people post entirely incorrect information is frustrating. You couldn't be more wrong on all counts. Google DOES NOT send IMEI ranges to other carriers. Your phone make and model can be identified by the first eight digits of your IMEI. It is called a TAC (Type Allocation Code). TAC tables are maintained by the GSM Association. The TAC is what the carrier uses to figure out what device you have. That's how it works. Trust me. I know.
[Samsung Galaxy Nexus] e-dub:
popped the sim in, didn't mess with any apn settings:

here's what i was getting with the nexus s, no messing with the apn settings there, either:

[Samsung Galaxy Nexus] BarryH_GEG:
I have no problem admitting I'm wrong. Most of what I've shared I picked up on the forums here. There's actually a site (http://www.numberingplans.com/?page=analysis&sub=imeinrf) that identifies a phone by its IMEI. It identified my SGS2 and UK Tab correctly. So why do you think AT&T can't identify international devices running on their network? Similarly, why do they identify and flag Nexi?
[Samsung Galaxy Nexus] s.m.knipe:
I see this as well, and wondered why HSPA+ seems to be "on demand"- There shouldn't be any battery savings as it is the same radios (I think) between normal "3G" and HSPA+... As long as speeds hold I am okay with it- just an oddity
[Samsung Galaxy Nexus] ranphi:
Interesting! I wondered in the back of my mind if it might have something to do with that. If it works properly and doesn't introduce any issues for data usage, then it seems like a good idea to me. Anything that can help extend battery life would prolly be appreciated by most people.

I'll be curious to see if any other phones start to adopt this technique, now.

Thanks for the info!
[Samsung Galaxy Nexus] VegUnited:
I just got mine into today, it won't send any sms or mms messages. I go into the *#*#4636*#*# menu and i don't have an smsc number in the box, and when I hit refresh it says 00 which obviously isn't correct, can anyone help me please?

Does anyone know if it should be set to wcdma preferred or the gms/cdma auto, im about to lose my mind
[Samsung Galaxy Nexus] mobilehavoc:
I heard there's a rumor that the Galaxy Nexus on AT&T has trouble in low signal areas with not getting a signal or switching radios, etc.

Anybody have any issues like that? I'm running on T-Mobile right now but thinking of switching to AT&T at some point.

Ahhh, the beauty of pentaband hspa :)
[Samsung Galaxy Nexus] sluflyer06:
READ CLOSER guys....my post says "KB" not "kb" KB=kiloBYTE. Translated about 7megabit. Thats what I see consistently, just today I've seen 10megabit a few times on downloads.

I wish people would pay more attention before responding. :rolleyes:
[Samsung Galaxy Nexus] jabberwocky127:
So on my grandfathered unlimited data AT&T plan, my GN will get flagged somehow as a Samsung Galaxy Nexus by AT&T once I start using data? What are the implications of this exactly; will I be charged, forced to change plan, throttled, a combination of some of the above?

Just want to know what to expect since the phone should see my hands on Friday.
[Samsung Galaxy Nexus] justabrake:
Nothing should happen ( no Price change ) I have unlimited grandfathered also

But when I had the AT&T SGS2 bought off contract and inserted my mini sim with an adapter into the galaxy coming from an iphone 4 it must of raised flags with AT&T LOL they messaged me telling me to contact them immediately so I called them and they asked what phone I had and I told them and then they must od=f ran something on me (took about 5min.) and then she said everything was OK but I could swear they throttled me down a little but I can't prove that
[Samsung Galaxy Nexus] jabberwocky127:
I have a Motorola Milestone currently and I use the hell out of the unlimited data and have never been bothered by AT&T, but it is a European phone and doesn't even use AT&T 3g bands (sadly I didn't realize this when I bought it), so I was just worried this new technology would bring hell down on me.
[Samsung Galaxy Nexus] justabrake:
I'll say one thing for sure when you drop that sim card in that phone it's going to explode with speed ;)
[Samsung Galaxy Nexus] jabberwocky127:
I know, I can't wait, haha..
[Samsung Galaxy Nexus] dawgpound6985:
Sounds like you lost your SMS Center number. You can call AT&T and ask for it or try using this one:

+13123149810

Its the one found on my phone. I lost mine as well using CM7 on my Galaxy S before and haven't had any problems since.
[Samsung Galaxy Nexus] Chirality:
700KB/s is 5.6Mbps.
[Samsung Galaxy Nexus] jopherr:
your problem was that you bought the AT&T SGS2. At&t has all the IMEI numbers of the phones they sell in their database.
[Samsung Galaxy Nexus] flyerwire:
my GN doesnt connect with the HSDPA APN. Is there any reason why it would happen? I've tried twice resetting the info in it, it just stays gray.

I have a really old SIM card in it, would that have anything to do with it?
[Samsung Galaxy Nexus] justabrake:
WHAT PROBLEM ? So they messaged me and asked me to call them right away I thought they were going to tell me I can't use that with the unlimited plan I have but they didn't, they wanted to know what phone it was and I told them and I told them I bought off contract but After that I think she throttled me down because I never seen such a phone with speeds like that WOW and I don't no why but my phone bill has never been cheaper then it is after using that and still is cheaper then I've been paying in years :D I only pay $84.71 a month for 450 minutes unlimited data and 200 messages Not bad for surf and talk @ same time.

No Problem here :)
[Samsung Galaxy Nexus] sluflyer06:
I'm running a GN as well and just now tried out the AT&T US HSDPA APN and it works perfect. (I did stop by a corporate store when I got it and got a new sim card for it and asked for it to be provisioned for HSPA+, they did it quickly, no hassle and for free, I was/am already on a grandfathered unlim. plan)

In fact I've done repeat speed tests on CIngular 410 vs. AT&T US HSDPA and results:

410: Average 7Mb

HSDPA: Average 9.3Mb 1.6up
[Samsung Galaxy Nexus] psero:
Any suggestions on how I could avoid my carrier from seeing my IMEI number and thus forcing me into a more expensive data plan? Possibly changing GN's I M E I to that of my old phone?
[Samsung Galaxy Nexus] flyerwire:
searching around i think i found out why i can't connect, my account has the old non HSDPA data plan on it.

I get signal on it, but it wont get data. My wife has an Atrix and it works fine (already has the settings on it)
[Samsung Galaxy Nexus] psero:
See here for the AT&T Galaxy Nexus

androidpolice /2011/12/02/samsungs-galaxy-nexus-stops-by-the-fcc-again-appears-to-be-headed-to-att/

Does this mean that AT&T GN is GSM/WCDMA and not GSM/HSPA+ like the international version?

Then the international version might be faster because it's HSPA+ (not WCDMA) right?
[Samsung Galaxy Nexus] mstyle88:
The article doesnt give a lot of info but it could utilize LTE 4G and skipping over HSPA+?
[Samsung Galaxy Nexus] dwboston:
No - that's not what it means. HSPA+ is an updated standard based on WCDMA. The GN will support HSPA+ when/if it reaches AT&T.
[Samsung Galaxy Nexus] jopherr:
if i had to guess, that would be At&t's version of the Galaxy Nexus and if you use the international version, you could probably get away with the dumbphone plan. kinda akin to At&t SGS2 & International SGS2

good news i'd say xD

An Update to my speeds, when I first posted I was only able to test buried within a huge building at work, once I got outside I was able to consistently hit 11 megabit.

Can anyone PLEASE enlighten me about this situation:

I have an imported Galaxy Nexus and want to use it on my AT&T family plan without switching to a more expensive plan. I also want to use data. Can I just switch my APN and get away with data? Is this possible or is switching to a smartphone plan inevitable?
[Samsung Galaxy Nexus] flyerwire:
went to my local store and they gave me a new sim card and updated my account for HSPA+ unlimited data, now the HSDPA APN works perfectly, and is about 2-3mbps faster per test!

I live in Denver, CO and used speedtest.net to test last night.

5.47mbps down

2.38mbps up

These are the best speeds I've gotten to date but I think our HSPA+ network is really only now lighting up. Typically, I get in the 2+mbps down and 1+mbps up.
[Samsung Galaxy Nexus] jabberwocky127:
Since changing my APNs to how this guy advised, speedtest has been acting very strange. It hesitates during download test until the very end, then usually gets me a score of <10kb/s, then it goes to upload and has 800-1200kb/s with my ping generally below 200ms.

I am a bit confused as my first test with the default APN gave me 226kb/s down, 93kb/s up and 268ms ping (which by no means is a good result, but at least it gives me over 6kb/s down, haha).

Maybe someone can share what they are using exactly on AT&T for me to try out?

As a note, loading a 1080p video in youtube goes without stutter, so it may just be that speed test is bugging out. Still, I would like some peace of mind that my phone isn't possessed by a demon or something.

[Samsung Galaxy Nexus] ianwood:
OEMs only supply IMEIs to the carriers that buy their phones. But let's not belabor the point. Just know that ALL GSM carriers can know the make and model of EVERY single IMEI out there. Therefore, they can ALWAYS know what device you have. ALWAYS. Unless you break the law.

And as the capacity crunch grows larger, operators are ramping up initiatives to put limits on service (incl throttles) where the device doesn't match the plan. I've worked on the deployment of two this year alone. So in all likelihood, if you aren't on a plan of equal value to what you are consuming with your device, you can expect to be limited. If not now, soon.
[Samsung Galaxy Nexus] pukemon:
Youre not going to listen. Google gave imeis to atnt. There are several threads about in various forums. Nexus one owners were sweating because many got caught and upgraded to from their current $15 data plans to smartphones. Its an easy search or you can keep babbling because you think youre somebody.

[Samsung Galaxy Nexus] wrayrb:
Hi there,

I moved the Sim Card from my old smartphone (Tilt) to the new GSN. I entered the APNs as shown at the beginning of this message. In the APN listing, the HSDPA is green dotted. When I go to the network operators, available networks, I select Scan and it finds AT&T. But when I select AT&T to connect, it says, "unable to connect to this network at this time, please try again later."

So I have not phone service. Can anyone help me get a connection to the network for phone service?

Thanks in advance.
[Samsung Galaxy Nexus] ianwood:
Well if someone said it in a forum, it MUST me true then! And I clearly do not have any knowledge of device management databases that provide TAC data to enrich CDRs used by billing systems to flag subscriber accounts with device/plan mismatches and ultimately force you to upgrade to a smartphone plan when you're actually using a smartphone! Yup, you're right. AT&T doesn't have that! Instead, everyone sends IMEIs to each other in a giant s**t storm of data. Great idea. You're a genius!

Just to clarify, if I see the 'H' on the signal bar, does that mean hsdpa is configured properly?

ok, so i came from my Samsung SG2 Skyrocket. Im on the LTE Unlim data plan. Im not in LTE area, but I was pulling nice speeds on the Skyrocket with H+. 5-10mbps pretty consistently.

I have not changed anything, just popped my SIM in GN and I am not seeing these speeds anymore. 1-3mbps is all I am getting. MMS works perfect.

There are several settings I am seeing posted, I dont know which I should even be trying. Anyone clarify which settings I should be attempting?

I also went to the AT&T store and got real good service. (See my story on the thread http://xdaforums.com/showthread.php?p=19983865&posted=1#post19983865 post 734.

You can do that, they probably can't update it through the register, but they CAN do it through a phone call to their customer service number.

BTW - You should have a Sim card in it, any old one will do. (Mine was from an old Sync cell phone.) They don't check the sim card other than to see if it is not working as it "should". They pop it out, put in a new one and set it up. Bingo!

I decided to go with the i9100 because of internal storage/SD Card. I have a micro sim adapter for my iPhone 4S SIM. Should I be able to just pop that in and get HSPA+ speeds and data? If not, what are the right APN settings? I've read/seen so many different ones.

Crud. Is it against AT&T's terms of service or against any sort of rules? I don't want to do anything that could be considered illegal for any reason. Not cuz I'm worried about getting going to jail or anything, don't worry, I'm not paranoid in that way

hey guys. I've been reading some posts in the Galaxy Note forum, where some of the At&t users have been getting blocked by At&t cus the notes shows up in the system as a galaxy tab.

so what some users did, was they backed up their /efs folders, and then empted the contents.

could someone try this on their Galaxy Nexus and see if they get similar results as this? I am currently contemplating on importing a Galaxy Nexus and I'd like a "backup plan" in case At&t starts blocking us

You know what? I just went on my AT&T account and looked at my features and I have the "2gb smartphone data", BUT if you have a 4g phone, you should be getting the "2gb smartphone data 4g" plan...and that's not LTE because they have another data plan that's "2gb smartphone data 4g lte."

So I'm thinking I'm only getting 3g speeds because of the plan. It seems like I need the "4g" data plan to get 4g data. I'm going to call them tomorrow and if they don't switch me, I'm canceling service and selling the phone.
[Samsung Galaxy Nexus] carrot34:
The "AT&T US HSDPA" APN setting (with the APN set to "phone") doesn't work for me at all: the phone just can't connect to data at all. (The ol' wap.cingular works fine.) Would this be because I don't have a 4G data plan? And is there any danger that asking for one would trigger AT&T's taking away my grand-fathered unlimited plan?

Thanks!

I brought my Nexus into a corporate location and handed it to the guy and he knew immediately what phone it was and was quite excited to see it.

I've tried to do this yesterday but the rep on the phone decided to act dumb and didn't understand me. Let us know how this goes for you.
[Samsung Galaxy Nexus] ianwood:
If you change to a different APN and you get no service from it, you:

a) didn't set it up correctly

b) are not provisioned to use that APN

c) all of the above
[Samsung Galaxy Nexus] brian85:
Well I just tried with online chat and she obviously had no idea what I meant:

"the data pro 4gb is $45"

What the hell? I wasn't even talking about the 4gb plan. Looks like I'll be heading to the corp store later.
[Samsung Galaxy Nexus] BarryH_GEG:
If you're on a legit 4G plan, you should use the 4G APN settings. If you're on a 3G plan (grandfathered, data for non-Smartphones) you should use the Cingular APN. Using the 4G settings on a 3G plan gets you no data. Based on experiences in the SGS2 forum, the HSPA+ speeds are the same for both. I traveled through TX with a friend with an Infuse who is on a 4G plan and when we tested speeds in a couple of different cities sitting right next to each other mine on my SGS2 (on a 3G plan) were the same or in some cases higher when his signal was weaker.
[Samsung Galaxy Nexus] Teklock:
I've tried all the APN settings here and none of them gets me anywhere near the speeds of my coworker's iphone 4. When I got my nexus I went to the corp store and asked for a SIM provisioned for HSPA+ but apparently it is not?
[Samsung Galaxy Nexus] brian85:
Well I went to the at&t store and they said they couldn't change my plan because the only option it let them put it on was the regular smartphone data plan. But I am getting between 3 and 6 megabits per second down so maybe I just don't have a good signal at my house where I was getting between 1 and 2. What exactly would be considered hspa speeds?
