Only in the U.S. is HSPA+ referred to as 4G. The SGS2 and GN are 3G phones. AT&T's marketing and plan definition is what's confusing. If you asked for a HSPA+ SIM in AT&T land that's a 4G SIM. If you're on a legit 4G plan it should work with the 4G APN settings posted elsewhere. If you're using a 4G SIM on a 3G plan that could explain your problem. It's gotten even more confusing because now there are 3G plans, 4G plans, and 4G LTE plans. At the end of the day if you have a HSPA+ device and are on the AT&T network you should get the best speeds available. I have friends that roam in the U.S. when visiting from overseas and they get HSPA+ speeds with foriegn carrier SIMs and no APN changes.
[Samsung Galaxy Nexus] brian85:
Good to know, thanks.
[Samsung Galaxy Nexus] ianwood:
Good point. I really hate that T-Mo and AT&T have marketed HSPA+ as 4G. Makes things really, really confusing.

Just to be clear, there are only two SIMs in circulation (not factoring different sizes): the older 3G SIM which I am pretty sure they don't give out anymore and the 4G SIM which allows for LTE compatibility. The 3G SIM should be fine with HSPA+ but I suppose having the latest one is the safest bet. They should be completely backward compatible. In other words, a 4G LTE SIM should work with everything.

What changes is your provisioning in the network (PCRF policy, PGW, etc). It seems there are four(?) service levels for data service at AT&T: feature phone 3G, smartphone 3G, HSPA+ (what they call 4G) and LTE (what they call 4G LTE).

It would appear that HSPA+ has its own APN which you can only use if you are provisioned for it. And apparently they require you have an AT&T HSPA+ device. APNs corresponding to your provisioned services should get pushed out at the time of provisioning via SIM OTA (which is a background function, you don't see it happening) but you can still edit them manually.

As for those international users roaming on AT&T and getting full HSPA+, you can bet they're paying for it!!!
[Samsung Galaxy Nexus] TroyBoy30:
you guys are still using the old non smart phone unlimited plans? And I thought I milked that pland for a long time! ;)
[Samsung Galaxy Nexus] Gary86:
I have a micro sim adapter and will be using my iPhone 4S SIM which is def a smart phone plan. I'm also on unlimited data, should I just pop my SIM into my i9100 (I know not a nexus but same concept) and be good to go?

AT&T guy said he would hook me up with a regular size SIM if needed.
[Samsung Galaxy Nexus] BarryH_GEG:
In name only. With the Infuse, they introduced "4G" plans that are routed through seperate servers and have different APNs. Those APNs only work if you're provisioned for what AT&T refers to as a 4G plan. Using those APNs with a 3G account/plan nets you no data. I'm on a $10 data for non-Smartphones plan and get HSPA+ speeds where they're available.

---------- Post added at 02:22 PM ---------- Previous post was at 02:21 PM ----------

I am. A friend who was on the same plan since May with a i9100 changed to a GN and got flagged. YMMV.

---------- Post added at 02:24 PM ---------- Previous post was at 02:22 PM ----------

It's not the SIM, it's the plan. You can't use an iPhone provisioned account with a non-iPhone device. I'm not sure, but I think they'll grandfather what you have and just move it to a smartphone plan. That's what I've heard others say.
[Samsung Galaxy Nexus] Gary86:
Ok, so I'll def need another SIM card from AT&T.
[Samsung Galaxy Nexus] ianwood:
Got it. What you're saying is the non-smartphone 3G APN isn't throttled which probably means the same for the basic smartphone 3G plan. So for those that aren't getting HSPA+ speeds, there are other forces at work. Either:

1. your network location doesn't support HSPA+ speeds

2. there's congestion preventing HSPA+ speeds

3. there's an individual throughput throttle on your account (not necessarily based on usage limits, but possibly IMEI or plan based.)

That's not to say they won't start limiting by APN at some point but that doesn't appear to be the case now.
[Samsung Galaxy Nexus] BarryH_GEG:
What's interesting is that the vast majority of people flagged for overages are on 4G plans. That would lead me to guess that part of the function of the 4G servers and APNs is auditing. I know of no one using an international device and the Cingular APN that's been flagged. The exception being Nexi but we've already had that conversation. I've never been below 4GB a month since May and had a month where I was at 10MB and haven't been flagged. People on the SR forum with grandfathered 4G plans have been flagged and throttled as low as 2GB with their only option being upgrading to a current metered 4G plan. How long the semi-free ride on the Cingular APN lasts is anyone's guess and it seems that AT&T's getting more deligent in policing data usage across the board.
[Samsung Galaxy Nexus] Gary86:
I'm on a iPhone 4S now. I have a micro SIM adapter but I heard that I can't use this sim in the i9100 bc its provisioned for the iPhone only. The AT&T local rep said he would give me a new SIM.

1. Can I just pop this SIM into the unlocked galaxy s2 and be good to go?

2. If it needs to be activated I don't know how I'm going to do this because the only phone I have is the iPhone and a regular sim won't fit inside that.

3. If I tell AT&T that my iPhone broke and my friend is letting me borrow his galaxy S2 and I get the SIM can they activate it without the phone?
[Samsung Galaxy Nexus] yegoshin:
FYI: Ipad SIM with adapter, APN:broadband gave a result of 10000kbps and tethered via USB gave a consistent speed of 1.3MB/sec

So I don't think its your sim card, its your account.
[Samsung Galaxy Nexus] ianwood:
If I had to guess, the newer infrastructure supports a lot more capabilities in policy control whereas the older infrastructure is probably still having it upgraded. CRM/billing sets up rules based on plan, IMEI, threshold limit, etc. that selectively provision restrictive policies on a subscriber by subscriber basis.
[Samsung Galaxy Nexus] Gary86:
Is that directed at my question? I haven't tried my iPhone sim yet. Going to get the phone from DHL now.
[Samsung Galaxy Nexus] yegoshin:
No 'your' is a generalization.
[Samsung Galaxy Nexus] Lootes:
So I got my GN on Sunday, put in my SIM card that I got when I bought my SGS2, didn't change anything with the APN. Just did a speed test in my office and pulled 5.2 down and 1.1 up.
[Samsung Galaxy Nexus] psero:
I have a question,

If I'm on a AT&T family plan and disable data (GPS&3G or w/e) and only use wifi and calls, would I get flagged and get upgraded to smartphone plan?

Thank ya!
[Samsung Galaxy Nexus] BinaryTB:
Yup, it's IMEI based, not data usage based.
[Samsung Galaxy Nexus] Gary86:
I popped my iPhone 4S SIM in with the micro sim adapter. I'm on the unlimited data plan already. Should I go and get the regular SIM from AT&T. The status bar says HPSA+ so I assume I'm getting those speeds. Things seem kinda quick.

EDIT: Did a speed test when it said H+ and the speeds are def NOT HSPA+.

I'm guessing I should go get a SIM from AT&T and ask them to make sure I'm able to get HSPA+ speeds? I thought I couldn't activate a new SIM in an unlocked phone? Please advise on best course of action.
[Samsung Galaxy Nexus] ianwood:
Your 4s SIM isn't the problem. Check APNs.
[Samsung Galaxy Nexus] Gary86:
Thanks for the reply. I've seen a bunch of different APNs on multiple threads/forums. Which one should I use to get HSPA+ speeds. My data is working (i.e SMS, MMS, etc)
[Samsung Galaxy Nexus] bblanski:
I got the same thing going on
[Samsung Galaxy Nexus] Gary86:
Hopefully someone can post the correct APNs...I've seen a bunch
[Samsung Galaxy Nexus] s.m.knipe:
They have been posted in multiple threads and places already. The rule of thumb is:

if you are on a grandfathered 3G data plan: use the WAP.CINGULAR APN

if you are on a 4G (HSPA+ NOT LTE) plan: use the Atrix's AT&T HSDPA APN & use the AT&T MMS APN

if you are on a 4G (LTE) plan: Use the Skyrocket's APN

There is evidence of interoperability between these, but that seems to be due more to the type of plan you have AND the towers in your location than just the APN and plan type.
[Samsung Galaxy Nexus] wrayrb:
If I see an H on the cell signal strength meter at the top, does that mean I have HSPA+?
[Samsung Galaxy Nexus] :
Somebody should put this in the first post along with the settings for quick reference.
[Samsung Galaxy Nexus] brian85:
I'm wondering this too. I'm still not sure if I'm getting HSPA speeds since I have the regular 3g plan.

What exactly is considered hspa? A majority of the time I get around 2mbps, but I've hit between 5-6 depending on locations.

[Samsung Galaxy Nexus] enumBoss:
Just wanted to chime in a bit here, too. I'm on AT&T with my Galaxy Nexus. I'm getting HSPA+ sometimes, but not consistently. When I do have it, it seems to swap back and forth between HSPA+ and 3G a lot. In fact, sometimes doing so leaves me without any data connection at all for a couple seconds. I can see this when I try to load the Market or some other internet required app. It will have me retry the connection occasionally.

Keep in mind, though, that I haven't received the OTA update that was being pushed out yet (some people here mentioned that it helped with their data connectivity). Also, I was looking in to the new radio that leaked recently, but haven't installed that as I'm unsure if installing that will prevent me from being able to install future OTA updated or not...
[Samsung Galaxy Nexus] Gary86:
As you can see in the pic I'm on HSPA+ and I changed my APN to the wap.cingular...didn't help at all.
[Samsung Galaxy Nexus] s.m.knipe:
What device is that?
[Samsung Galaxy Nexus] BarryH_GEG:
Are you sure? I was never on an iPhone plan and don't have first hand experience but I've read in other threads that the account needs to be reprovisioned to a smartphone (vs. iPhone) plan for data to work properly.
[Samsung Galaxy Nexus] Gary86:
Unlocked i9100 (galaxy S2) Speeds are bad on both stock APN and wap.cingular.

p.s. I know this is the Nexus forum...I'm the OP and decided to go with the S2. I have a bunch of movies on my phone for my daughter for when we travel.

If I call AT&T and ask to have my plan be the smart phone bc I'm using a Galaxy S2, will I get flagged for using an unlocked phone and not be able to use on the network?
[Samsung Galaxy Nexus] brian85:
Why would they block you? It's not illegal to use an unlocked phone. I went into the store yesterday and straight up told them I'm using an unlocked phone.
[Samsung Galaxy Nexus] Gary86:
Ok, I thought I read some where that they don't like unlocked phones on their network bc you didn't buy it from them. I'll call 611 after I get off work.
[Samsung Galaxy Nexus] s.m.knipe:
No worries, I just saw that and thought "wait a second, that's not an ICS notification bar"

They don't like it, but they cannot deny you service (unless they can show that your device is a safety hazard- i.e. crashing the network or infecting other devices). Your contract with them is for service to the device, not the device itself.
[Samsung Galaxy Nexus] s.m.knipe:
Also, just as an oddity: I know we have discussed AT&T knowing what device you have, I thought it was surprising and odd that Google knows what carrier your device is on (see attached screen shot where the device appears).

What I found odd is that this was an option that the Android Market had been coded to reply with to the query for device ID. Could this be an indicator for an eventual GSM GN here stateside? Does anyone see the same on T-mobile? I was expecting it to say "International Samsung Galaxy Nexus" or something along those lines- not be carrier specific.
[Samsung Galaxy Nexus] Andrmgic:
yeah.. google knows I'm on AT&T too.. interesting.
[Samsung Galaxy Nexus] brian85:
Would this be considered hspa speeds? What sucks is I rarely get this, but if I am getting it sometimes then I should be getting hspa no problem right?
[Samsung Galaxy Nexus] :
Well you aren't really hiding it...
[Samsung Galaxy Nexus] Gary86:
So by calling A&T and requesting a move from the iPhone plan to the "smart phone" plan I should be getting HSPA+ speeds? Just need to make the call huh?
[Samsung Galaxy Nexus] brian85:
Hopefully. The iphone plan is just the regular 3g smartphone plan. They need to move you to the 4g plan (not the 4g lte plan, which is a separate one).

I'm going to make the call also in about an hour.
[Samsung Galaxy Nexus] Andrmgic:
Of course not :)

I just think it is interesting that google adds that to the device name.. I've never seen them specify with other devices I've had..
[Samsung Galaxy Nexus] Gary86:
I'm at work for another 5 huors...can u let me know the results please.
[Samsung Galaxy Nexus] ianwood:
Yes, it sounds like you need to be provisioned in the network differently but the SIM should be the same. AT&T only has only one SIM they issue at a time (not counting the different sizes). If you got a SIM with your 4s, then you have the latest one.
[Samsung Galaxy Nexus] brian85:
No luck. They say there is no way for them to change it, so I might cancel and just buy the verizon nexus.

I'm not going to stick with regular 3g speeds when I have an hspa phone and can't even use hspa speeds. Ridiculous.
[Samsung Galaxy Nexus] Gary86:
Ok. The SIM is from my iPhone 4 that I just put in the 4S. I will call 611 and ask to be moved to a smart phone plan vice a iPhone plan. Unless my local store can do this.
[Samsung Galaxy Nexus] brian85:
Only thing I can think of is using my friends HTC Inspire 4g, popping my sim card in there, putting the 4g plan on, and going back to my nexus. Not sure if that would work though.
[Samsung Galaxy Nexus] Gary86:
Are you serious? They couldn't switch you to the HSPA+ (smart phone) plan? Did they say why not?
[Samsung Galaxy Nexus] brian85:
back on the phone again and finally reached someone who knows what the nexus is! he knows exactly what i'm trying to do....hes got me on hold right now fixing it for me.

guess you just gotta keep calling til you find someone who knows what the galaxy nexus is.

---------- Post added at 01:28 AM ---------- Previous post was at 01:26 AM ----------

the lady said theres no option to. she obviously didnt know exactly what i wanted. this guy on the phone with me now knows exactly what i want and hes working on switching it over.
[Samsung Galaxy Nexus] aimetti:
Do any of you guys have issues with your SGN on ATT?

I know its not the perfect thread for this but i have had nothing but problems so far.

I have tried reprovisioning sims , different data plans , replacement nexus.

Nothing has worked. I tried some of the APNs including the hsdpa one in here and it gets me great speeds for my area but after a while my signal drops and doesnt recover.

I just recently activated my 4s and have been swapping sims to monitor signal and the iphone 4s right next to my nexus is at -84 dbm and my nexus in the same area fluctuates between -95 and -107 dbm which is awful.

Could my plan just be really messed up and causing all the mess. Or is possibly the APNs etc. I originally came from an iphone data plan.
[Samsung Galaxy Nexus] Gary86:
Please ask them while you have them on the phone what I should ask for verbatim. I don't wanna have to call multiple times

thanks bro
[Samsung Galaxy Nexus] brian85:
Ok, a lot of people talk bad about AT&T's customer service, but this was outstanding.

This guy did literally everything he could to get my plan to the HSPA plan. The system wouldn't allow him to manually override it no matter what (since our unlocked galaxy nexus shows the phone on AT&T's system as a non 4g phone), so to make a long story short he activated an atrix on my account to switch it over to HSPA and now I'm good to go. :)
[Samsung Galaxy Nexus] aimetti:
Talking to to att , the phone was originally setup on 4G LTE instead of 4G HSPA (they really need to fix this naming convention)

they are changing to the correct one and i will test and report.
[Samsung Galaxy Nexus] brian85:

So I ran a speed test finally. It says I'm getting 9 kbps down and 2704 kbps up with a 207 ms ping. This seems just plain wrong. I can download apps with almost no issues and the web browser feels much faster than it was on my Nexus One. I checked the link above here and will be calling AT&T about the correct SOC on my account, but I don't want to lose my unlimited data. :(

A lot of times it's the server you pick also. Go to "tools" in the speedtest app and try each server down the list.
[Samsung Galaxy Nexus] enumBoss:
Yeah, that doesn't seem to matter. All of them provide similar results.
[Samsung Galaxy Nexus] rlsroufe:
Finally got it switched after almost 2 hours on the phone. I had to threaten to switch to T mobile, but they still were saying they couldnt do anything about it because the phone isnt in their system and they arent able to switch. But they did say that if i had an IMEI number for one of the HPSA+ phones in their system, i could give them that. I googled an IMEI number for an Atrix 4g (dont know who's it really is) and gave them that. It worked, now Im on the 4g hspa+ plan.
[Samsung Galaxy Nexus] clcross18x:
Yea, just to confirm, we do need the IMEI of one of the HSPA+ smartphones in order to put the correct data plan on. Otherwise the option for the proper data plan doesn't pop up. Should be fine if your switching from one of the HSPA+ phones already. If not then I would suggest using a friends IMEI on your line. I would give out my ATRIX IMEI, but I'm not entirely sure employees are allowed to do that. It's a recession you know.....gotta keep a job!

If that doesn't work, then a simple Google search should get you the IMEI for one of the smartphones that require that plan.
[Samsung Galaxy Nexus] ericshmerick:
Since it seems you work for AT&T, I have a question for you.

Once upon a time, I had an Atrix on my ATT account. I have unlimited grandfathered data. Here is what my plan says (attached). Do I have HSDPA+ 4g on my plan?

My device is listed as "unknown." I'm not sure if I still have the 4g plan...since I've been through several unlocked phones after my Atrix and prior to my GNEX.

Thanks.
[Samsung Galaxy Nexus] clcross18x:
It looks to me as if you have just the regular smartphone data plan. From what I can remember of my plan the last time I logged into AT&T, the title of the proper data plan says something like "Smartphone Personal for 4g HSPA+" or something of that nature. The codes we use in store are a bit different then the ones that show in the online management account.

What I'm hoping doesn't happen is that because the IMEI from the SGN doesn't register as an actual HSPA+ device that AT&T carries, that the system sweep continually boots users down to just the regular smartphone data plan. I've seen data plans stick on even after the customer switches from a Blackberry or iPhone to a regular flip phone, and I myself have switched between the HSPA+ devices. But this would be a new situation for me.
[Samsung Galaxy Nexus] milan03:
You need code: HSDPPB which stands for High Speed Data and it's given to HSPA+ capable phones. I switched my iPhone Unlimited using Infuse 4G, no issues. Speeds are not much different though, but on my account I can see the proper code being applied.
[Samsung Galaxy Nexus] CraigP17:
Coming from the skyrocket, I am on the lte 4g plan. I never experienced lte but my h+ speeds were great. Not as fast on my nexus.

Would I benefit from switching to the non lte 4g plan? I wouldn't think so but am I wrong?
[Samsung Galaxy Nexus] clcross18x:
I wouldn't if your speeds are fine. I mean when you stop to think about it you already are on an HSPA+ data plan since the whole purpose of them using HSPA+ and LTE was to provide a "smoother experience" or whatever. The data plan your using has to be provisioned for HSPA+ or otherwise you would be getting 3G speeds.
[Samsung Galaxy Nexus] CraigP17:
That's my thinking but my speeds don't even compare to the h+ I was pulling on the skyrocket...
[Samsung Galaxy Nexus] milan03:
I can confirm this. Before I returned Skyrocket I used to pull in 14mbps with 36ms latency. On Nexus I'm pulling half of that and 100ms latency. Spikes at about 9.5mbps.

Not sure if it has something to do with the IMEI not being in their system or what...
[Samsung Galaxy Nexus] clcross18x:
Honestly I've never seen anything higher than probably 4.5 Mbps and I'm in Atlanta where AT&T corporate headquarters are. I keep reading stories of people getting 8 or 9 and I'm wondering where the heck they live!
[Samsung Galaxy Nexus] ericshmerick:
In a non over saturated market?

AT&T blows in big cities. Having the corporate headquarters matters not.
[Samsung Galaxy Nexus] enumBoss:
Will be calling in the morning since the call center is now closed. But don't the tech reps have demo phones on the floor they could use to help you switch? We sure as heck did when I did tech support for US Cellular...
[Samsung Galaxy Nexus] AirBaker:
Exactly. I posted this in another thread, but it applies equally here as well:

This is *exactly* the problem. Here are my AT&T HSPA+ speeds on my GSM Galaxy Nexus:

From my house -- 5 mb/s

From random place in the west part of the city -- 10 mb/s

From downtown at 10 PM -- 5 mb/s

BUT, from downtown during the business day, when it matters -- 0.5 mb/s

It's what I call the football game effect. At a football game, AT&T phones get basically zero service, whereas Verizon's CDMA network is capable of normal speeds. Downtown has that same issue during the day, as will any crowded area (shopping mall, etc).
[Samsung Galaxy Nexus] CraigP17:

Tried this and it got me the h+ speeds I was getting on my skyrocket (5mbps and higher down. 2mbps up.) but mms not working now.

[Samsung Galaxy Nexus] milan03:
Anyone on iPhone 4 or HSPA+ data plan got Nexus to work on "pta" APN?
[Samsung Galaxy Nexus] AirBaker:
No, but it's easy to get your account LTE provisioned if you go into the store, at which point you can use PTA. I made a thread a while back on how to do this, but I can't find it now. I've done this and so have 2 friends.
[Samsung Galaxy Nexus] carrot34:
Hi, All -- I'm confused about the PTA option, and I'm hoping someone here can help me understand it. What is the PTA APN? What does PTA stand for? And if it's for LTE, should it make any difference on a phone (like the GSM Galaxy Nexus) which doesn't have LTE?

[For reference, there's a whole thread about the PTA APN here: http://xdaforums.com/showthread.php?t=1372040]

[Samsung Galaxy Nexus] winterhaven:
Which of the many floating around are the correct 4G APN settings?
[Samsung Galaxy Nexus] bmolloy:
The work around for that is pretty simple. Turn on Airplane mode, then turn on your wifi and connect to a wifi hotspot. With the Cell Radio off it will only show your phone as an android device to the market, not a carrier specific device. This will allow you to download all of the things AT&T has asked google to block. I have not tried this with the Galaxy Nexus (it is in the mail) but it works great with my nexus one and Inspire 4G.

I just ordered my gsm nexus! So when I get a new sim card provisioned for it will the vpn settings already be set up? Or will I need to do something like that manually?
