AT&T APN switching to PTA on Galaxy Nexus

EDIT: OP EDITED WITH CHANGED PTA SETTINGS UNDER APN TYPE!
After reviewing the GS2 thread on the same topic (http://forum.xda-developers.com/showthread.php?t=1109983), I thought it might be worthwhile to discuss this issue on the Nexus. I was not able to get the Nexus connected using the information in that thread. However, I was able to get it connected to pta using a slightly modified version of the Skyrocket settings, which I'll post below.
One quick question before I do that, though -- I am only able to get 3 mb/s or so on my Nexus. I am on the unlimited data SOC code for LTE: LDPPVM5 -- think that code is causing any problems?
Anyway, here are working settings to get to PTA (the one the Skyrocket uses):
1) Go to settings, more (under networks), Access Point Names
2) Click on the 3 dots to create a new APN, name it AT&T PTA, and enter the following:
Name: ATT pta
APN: pta
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMS Proxy: not set
MMS port: not set

MNC: 410
Authentication type: not set
APN type: default,internet,supl [NOTE NO SPACES IN THIS]
APN Protocol: IPv4
APN enable/disable: APN enabled
Bearer: Unspecified
3) Then separately create another new APN and enter the following:
Name: AT&T US MMS
APN: wap.cingular
Proxy: wireless.cingular.com
Port: 80
Username: not set
Password: not set
Server: not set

MCC: 310

Authentication type: not set
APN type: mms
APN protocol: IPv4
APN enable/disable: APN enabled
Bearer: Unspecify
4) Make sure the little circle next to AT&T pta is green.
5) Wait for the device to connect and then restart it.
I had a hard time finding these settings, so I thought it might be helpful to someone else here.

No. Bad joke.

Not to be too paranoid, but will messing with these settings make it appear you are, say, tethering? I don't want to lose my unlimited data on ATT and fear that changing anything to access faster speeds may flag me for using a computer?
Similar to when the Dolphin desktop mode was flagging people on ATT, prompting the carrier to accuse users of tethering...

I wasn't aware Galaxy Nexus had the proper radio for this...

Are you using AT&T's LTE provisioned SIM? that's probably why you're seeing the issue. Also that SoC code is LTE provisioned code which doesn't help.

I am using an AT&T LTE provisioned SIM and my SOC code is LTE, so that could be part of the problem. But also keep in mind, I had that done just in case AT&T ever started to refuse to upgrade unlimited data users to LTE unlimited data. Right now, they're eager to get the LTE towers full, so they won't stop such upgrades -- that may change in the future.
Anyway, I played with my settings for a long time tonight and realized that APN type needs to read "default,internet,supl", not just "default,supl". I have no idea what that means or why it matters, but when I changed that, my speeds definitely increased. To give a comparison, at 1 AM, I got the following speeds:
default wap.cingular APN -- 4-5 Mb for most test servers
phone APN (as described in the thread linked in the OP) -- Average of 5 Mb for most test servers and high of 6 Mb
pta APN (as described above) -- average of 7 Mb for most test servers and high of 8 Mb
The difference isn't exactly extreme, and it's far lower than I'd hoped for, but I think pta is demonstrably faster, at least in my area. I'm eager to see how it does during the work day tomorrow.

I just tried this in Saint Lous, MO and I get no data service with pta

Are you sure this line was exact (with no spaces)? Without "default" there it won't get me data services either, but with it I do:
APN type: default,internet,supl

No data for me either, reverted back to the dault cingular apn...though the HSPA+ phone APN that is floating around these board damn near doubled my speeds.

Just curious... If the HSPA+ APN doubled your speed, then why go back to the default cingular settings?

Im confused, why would the PTA apn do anything in the first place? i thought the i9250 version of the GNex isnt equiped with an LTE radio. Im in Los Angeles, CA where theres no LTE, i cant even get data with the PTA APN on my skyrocket. Unless I am mistaken and theres an LTE radio? id be so happy. Can anyone confirm? GSMARENA.COM list the specs for the i9250 with LTE 700mhz but other sites dont.

The 9250 doesn't have LTE. It's HSPA+.

It does not have LTE. It has HSPA+ (which AT&T and T-Mobile advertise as 4G). The poster here was saying he previously used a Galaxy S II Skyrocket (which is an AT&T LTE device) and because of that, his data plan is LTE and his SIM is an LTE SIM.
Anyway, I used the APN settings listed around this board and it doesn't seem to make a difference. When I used the settings posted, speedtest wouldn't work properly. It said I was getting 7kbps when it clearly wasn't that slow in real world usage. Going back to default fixed that issue, but I'm only getting about 3.5mbps down. I'd be happy to be getting 5. I already called AT&T and confirmed I've been changed over to an HSPA+ data SOC. Also, I got a new SIM card yesterday since my last one was from when I got my iPhone 3GS a couple years ago.

If you have an LTE SOC, you can use the LTE APN but the device doesn't support LTE. You might as well get the HSPA+ SOC and use the HSPA+ APN.

Using the latest AT&T LTE compatible SIM will not cause a problem. It is backward compatible with all AT&T plans. As for an incorrect SOC, well that's a different story and may have unpredictable results although a number of people have different SOCs/APNs working to their satisfaction.
Since a lot of people here think the LTE SIM is not compatible with HSPA/HSPA+, I am posting part of an official communique for "company owned" device users that went out just before the new LTE SIM was rolled out:
ATT said:
Next Generation SIM card for 4G devices now available
The new SIM card for 4G LTE devices is available for ordering in the COU system. While this SIM is required for 4G LTE devices, it is also compatible with 3G devices and COU will be shipping the 4G LTE SIM with every device make and model going forward (with exception to iPhone 4/iPad 3G +WiFi).
The new SIM (SKU 73057) includes enhancements that will enable functionality for LTE capable devices when supported by the network.

my account is LTE provisioned too(came from skyrocket) and these are almost the exact settings I ended up with as well after messing around with them and comparing with other skyrockets and SG2.
i have not been using the "internet" in the "default,internet,supl" setting, I just had "default,supl".
i have added the internet to see if I see any changes. these are the fastest Ive been able to get my GN to perform at. still not as fast as my skyrocket was using h+, and the MMS take a while to send/recieve sometimes.

Confirm that after obtaining new SIM to replace my 3 year old one and provisioning with a Skyrocket IEMI with LTE unlimited data plan I now am regularly 5Mbps down and hit 7-8Mbps at times. Latency is around 130ms.
MMS not playing nice. I haven't tested send and receive enough to say it works for me or not. I'll check in the morning when texting.
updated: no mms

Yes. Thank you. I did do so. My calls to ATT level 2 tech support and then a Supervisor now claim my issue is related to provisioning. The sim is correctly provisioned as pta with APN type settings as default,internet,mms,supl. I am told my account settings as part of my customer profile does not correctly reflect my IEMI and therefore my MMS feature is wonked. Sounds like I am in the customer service black hole waiting for my service ticket to make it through helpless-desk hell. There is something to what I am being spun because my online account is all screwed up. I love smartphone gadgets and hate wireless carriers!

Ok, for the sake of argument, try this please and report back. I have a Vivid that I bought unsubs, therefore I didn't get it from at&t, but from Tigerdirect.com and I had to set my apn because I live in York, PA and there is no LTE here. I am able to send and receive mms and access internet at 6+ mbps and I didn't call at&t to report my new phone. Here are my APN settings:
I setup 2 apns, below are both:
APN1:
Name: AT&T HSPA+
(everything else leave blank until the end, which you will
APN type: default,admin,fota,hipri
APN2:
Name: AT&T MMS
APN: wap.cingular
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: 80
APN type: mms
Those are my settings and again I can send and receive MMS and access internet. Ensure the radio is clicked on AT&T HSPA+
Hope this helps.

[Q] CM10 ATT - h+ but no 4G

I finally got around to flashing CM10, but can't seem to get the 4G working. I get H+/3g data, but no 4g. I flashed the CM10 nightly from 10/2.
My IMEI is in tact, I know the modem I am using works correctly in this area.
Here if my APN information:

Has anyone else run into a similar problem?

I realized I had a similar problem on CM9 and found two things:
1) APN type: default,supl,mms,hipri
I added hipri to APN type (not 100% sure it was needed)
2) In mobile network settings I had not selected LTE in the Network Mode option list. (THIS was my problem) It's one of those, duh of course I have that set moments..when I really didn't. So double check that setting.

First of all...are you in an LTE area? When you were on an ATT rom did it say 4G LTE or just 4G?

I believe THIS was my problem. On ATT roms it would say 4G (I'm not in an LTE area) - apparently on CM roms this translates to H+. Looks like I never really had a problem at all.
Thanks! Consider this solved.

You shouldnt refere to to LTE/HSPA+ as 4G. Just name it by what it is. Much eqsier to identify what the problem area is.

Change the following in your APN settings this resolved many 4g signal issues. I take no credit for this whatsoever. This was from another poster and I had these settings saved I just can't seem to find his post otherwise I would have linked it directly.

Have you actually ran speed test to confirm network speed?

Im actually having the same problem... Im using the infuse 4g with a cyanogen 4.2.1. Iunlocked my phone and am using a t-mobile sim (therefore, towers) and even though my phone is staying in one place the signal is going from E (econ, 2g) to 3g and H ( basically 3.5g) (back and forth) and never really stops...also the signal will be at full bars, then drop to no service and do it all over again.
Im obviously having service problems when i shouldnt and im not sure if im getting 4g at all even though i called and they said my plan was full-time 4g depending on coverage... OR..." H " is mobil's name for 4g (actually HSPDA + HSUPA which is technically considered 3.5).. Any help on the matter would be greatly appreciated.

[Q] Constently Losing Signal On My S3 While On 3G Only APN pls help!!

Constently Losing Signal On My S3 While On 3G Only APN pls help!!
Galaxy S3 AT&T 16GB rooted but never use the root nor made modifications im running Jelly Bean 4.1.1.
Below is listed two APNs that I use to get strictly 3G/4G network because I want to save my battery on my AT&T Galaxy S3 running Jelly Bean 4.1.1. I don't want my phone looking for nor connecting to the LTE network. But I run into the problem of constently losing signal randomly while running on either of the 3G/4G APNs I have manually set. After I lose signal my phone reconnects within two minutes back on to the 3G/4G network which is what I want it to do. But I dont want to have the problem of constently losing signal. I never lose signal when I have my APN set to the orignal APN that came already set on my phone which is called "ATT Phone".
When I do lose signal its not like im in a poor signal area. I have an iPhone 4S aswell and I never lose signal while I do on the Galaxy S3. The iPhone is on AT&T as well.
I live in Plano TX which is an LTE area
Are there other APNs I can try for AT&T? Do I have something set wrong listed on the two APNs listed below?
Any help would be appreciated,
Thanks

A APN isn't what you need. Use your regular LTE APN but set the network mode to GSM/WCDMA preferred.

Hate to be the bearer of bad news...but this happened to me not too long ago. AT&T did a diagnostic on my phone and the sim connector was screwy. I had to send it in for repairs.

How would I set that?

T-Mobile 4G on ATT GSIII

Hi
So long story short, my Tmo GS3 got stolen at my work :/
So my mom gave me her ATT GS3 cus she was up for an upgrade,
i been reading its possible to get 4G on an ATT GS3 but so far no luck,
i know i have the right APN cus i copied the one from my Nex4 to my GS3, i set the network to manual and choose Tmo, but still all i get is Edge.
Does it have to do something with the way i unlocked the phone?
I been reading it has to be factory unlock and i unlocked mine by dialing *#197328640# and doing the required steps.
Can anyone help me with this?

Do a little bit of search work; it depends on the coverage for T-Mobile in your area. It's still a Work in Progress to get the 1700 Mhz band to work on a ATT GS3 since there's a bounty for it in the General section.
Setting the APN to what you have on the Nex4 won't do anything because it's all software and hardware controlled. The software part is currently locked down because no one knows what to change to get the hardware to send and recieve information from the 1700Mhz Band.
Your best bet is to check the coverage map and hope you get 3G service or wait until T-Mobile Rolls out their 4G so the old EDGE will switch onto HSPA for ATT devices that use a T-Mobile Network.
Hope this helps

Try these apn settings if they arent what you're already using. They've worked for S3 users before.

Do a little bit of search work; it depends on the coverage for T-Mobile in your area. It's still a Work in Progress to get the 1700 Mhz band to work on a ATT GS3 since there's a bounty for it in the General section.
Setting the APN to what you have on the Nex4 won't do anything because it's all software and hardware controlled. The software part is currently locked down because no one knows what to change to get the hardware to send and recieve information from the 1700Mhz Band.
Your best bet is to check the coverage map and hope you get 3G service or wait until T-Mobile Rolls out their 4G so the old EDGE will switch onto HSPA for ATT devices that use a T-Mobile Network.
Hope this helps

I had the same situation: only edge, after flashing this files i have 4g http://forum.xda-developers.com/showthread.php?t=1771021&page=25.
Start reading from post #246. If you flash the files you must root your phone like it is a t999, also goes for recovery, im not sure about kernel and DO NOT flash another modem/radio.

No network on US version with ATT

Hi, I was wondering if anyone else had a similar problem or can help with a solution. I just got my Oppo 7 (love this thing) but it seems the network doesn't work properly. The network seems to be picked up just fine, full bars, under network settings it automatically acquires the APN settings and everything, but I can't do anything over the air without WiFi. As soon as the WiFi is gone, I can't browse the internet, send or receive text messages, etc. What do?

Will this help? Won't be LTE, but H+ (my phone doesn't have LTE)

I have mine set up on T Mobile and I'm having the same problem. It's pretty annoying. I've tried a factory reset to no avail. My phone downloaded an update this morning which I hoped would fix the problem, but it looks like it hasn't.

That's odd. There's one thing wrong with this device on stock - its APN database for AT&T is 3-4 years out of date. It was still using the wap.cingular APN when I turned mine on.
You need to manually put in the AT&T LTE APN (pta). ALSO if you've never owned an LTE device before you'll need to talk to AT&T to have your account updated. (Using the pta APN with a Nexus 5 resulted in no data for me too until I had my plan/account updated. You can do this without an actual contract change - for example I'm still grandfathered in to "unlimited data"). In general I would recommend doing this in-person at an AT&T-owned store, not at the phone and not at a franchisee (like most small mall kiosks).

Thanks for the reply everyone, I entered in the new ATT HSPA+ APN and it works like a charm now.

Could you post your settings?. I confirmed the SIM I got yesterday was lte capable but still no dice.

Just putting in the pta APN with no other info was enough for me.
(MMS is probably borked for me until I fill in the right settings for it but I use MMS maybe once every 3 years at most.)

I just realized that you were in here Entropy. I appreciate the work you did with the Galaxy S2 (last phone I had before this one). Do you plan on doing any dev work with this one or are you going to take it easy?

I'm working on lighting up omni. Oppo sent us a few devices.
Thanks for the MMS info, I should stick that into my device.

I pulled the APN configs for ATT Phone APN from omni's github (I updated it a few months back to what it was from an AT&T stock TouchWiz Galaxy S4 ROM, so it this is update-to-date afaik)

I have this as my settings now and still only get H+. (except for the mmsc, you have 3 m's)
Weird thing is that I get 0 connection when I change from phone to pta.
Not sure if locale is the culprit. I'm in Oklahoma City.

whoops made a typo, yea it's only 2 m's in mmsc

that's weird. did you call AT&T to confirm that you have the LTE data package on your account like Entropy512 stated ?

I went to the ATT store, but they weren't any help. They confirmed that the SIM they gave me was lte compatible, but I assumed that's the same thing as having an LTE data package. I'll give them a call tonight and let you all know. (btw, just re-applied your settings and still no luck)
edit: called.. and they claim that all accounts have lte compatibility now and of course she had never heard of the OF7a

The settings entropy posted were the exact settings my N5 had which I copied over and worked fine. One thing to be aware of is that mine says 4G on LTE and then either H or H+ for those, not sure if this applies only to my service area or what and another might show differently. At any rate if you're getting 4G showing you might wanna run speedtest and see if you are getting LTE.

AT&T's SIMs have been LTE compatible for years, even before AT&T had an LTE network. I need to check to be sure, but I'm fairly certain my SIM is still the original "cut down SIM" that I've had since 2011 at least.
It's your account that needs to be LTE-enabled.
Don't call. Phone support is awful. Go to a corporate-owned AT&T physical store. That's where the competent staff are.
(In my case, I originally did the LTE upgrade on a Nexus 5 - if you put a SIM into a Nexus 5 that doesn't have LTE on the account, you'll get a text message saying to call AT&T.)
