I think there are changes you have to make to the settings.
I would check NotionInkHacks forums to find the threads on that.

this may or may not be related to your problem, but did you add in the AT&T APN into your NI and have you tried your SIM card into a phone that can handle data on the AT&T network?
To input the APN info goto settings, Wireless & network settings, Mobile networks, access point names. Click your second to last button and click New APN. If the info for the field isn't provided below, leave it blank.
APN info:
Name: whatever_you_want_the_name_to_be
APN: wap.cingular
Username: [email protected]
Password: cingular1
MMSC: http://mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS port: 80
MCC: 310

I can confirm this works. The tablet does everything except receive phone calls.

Adam + AT&T Data only plan for Tablets.
I went to the store asked about this, the rep didn't know how to activate the Tablet Plan on a 3rd party Tablet. He suggested I call Customer Service. I asked him for a SIM to take with me when I call so I could save time and get it working.
I called CS, talked to about 6 reps~, they tried. The main issue was getting past the accepting the terms and conditions via the phone system (IVR), it kept coming back with Unable to process due to technical problems with their system and it would transfer me back to a rep. Reps tried this themselves with me on the line.
BTW, the reps bent over backwards to help. One of the most helpful, I got disconnected while calling another department and working with a supervisor. She called me back a few mins later, says she didn't call me back right away because she wanted to finish her call and have a definitive answer.
She said I would have to return to the store and have them set me up with a dummy tablet to activate the account, then make the appropriate changes in their system.
So today I went to a AT&T retail store once again, but armed with those notes in the account. The rep called, they told him he couldn't do it. So he called another department, had them activate my account using a dummy phone under a voice plan.
Once active he made changes in the account, entered a dummy tablet IMEI then changed to the $25 /2G data plan.
I popped in the SIM, ran through the steps of enabling it on the Adam. 3G icon appeared, tested surfing Google.
I had already added an APN, only editing two things, name AT&T, APN broadband, left everything else default and it worked (this is for data only, voice/data plans require more info edited).

[HELP] Got AT&T sim into International S3, calling works but data doesn't work

I got an international S3 from India and went to AT&T store to get a micro sim.
Got that installed and then the phone calling works fine but data (internet) doesn't work.
They said they would have to register my phone's IMEI but it still doesn't work. They put in a new APN, and still same. They called their tech and they couldn't help. Their last suggestion was to try calling Samsung, but I had to leave to get to work.
I believe there are already people using International version with AT&T for the S3. So any ideas what could be wrong?
Thanks!

Try factory resetting your phone. Other than that, make sure you have the $10/month data plan (unlimited messaging required) or the $15/month data (no messaging required). To do that you'll have to call into customer care and say you have an unlocked non-smartphone. If you go into the store to do this they'll give you the more expensive internet because they'll see you have a smartphone. If you're changing data plans it CAN take 24-48 hours for it to be effective, although it usually doesn't take that long. After that's done go into Settings, More Settings (under Wireless and Network settings), Mobile Networks, and then Access Point Names. Make sure there is an Access Point Name titled "Cingular 410". If there isn't then press Menu, and then "+ New APN". The settings should look like this:
Name: Cingular 410
APN: wap.cingular
Proxy: Not set
Port: Not set
User name: [email protected]
My Password field is auto-filled, so I don't have that. Try leaving it blank, but if that doesn't work call customer care and get that information.
Server: cingulargprs.com
MMSC: http://mmsc.cingular.com
MMS proxy: wireless.cingular.com
MMS port: Not set
MCC: 310
MNC: 410
Authentication type: Not set
APN type: default,supl,mms
APN protocol: IPv4
Enable/disable APN: Checked (this field is grayed out for me, but it is checked)
Bearer: Unspecified
This should fix it. The only thing I'm unclear on is the Password part.

Password is (all caps): CINGULAR1

Well now my SIM is completely unregistered, can't even make calls. Operator asked me to go to the store and get a new SIM Card.
So, this won't work without the switch to the non-smartphone data plan? It is going to be hard to pull off when I am in the store.

It should work just fine on the smartphone data plan, and you should be able to switch to the non smartphone data plan afterwards.

Ok, thanks. What should I tell the AT&T store people today when I go in the evening?
It feels like they did something on the account to screw it up. Would it help to suggest that they get this working on an AT&T HTC OneX and then transfer the SIM to my phone?

It could be that you have a defective SIM card. Take it one step at a time. Replace the SIM card. Make sure you have functionality with other services (such as voice and messaging). Check all the APN settings to make sure those are correct. Make sure you have a data plan for AT&T.

I'm on another carrier but I had the same problem at first, only phone call and sms working. I had to change my APN for the Data to work.

What are the APN settings you input, did you save and select it afterwards?
EDIT: Check the settings in the screenshots on the first posts of this thread, yours should match.

Thanks, I went back to the store. We got my original S2 working and this time switched to micro sim without making any IMEI/etc changes and it worked.
Anyone know what extra steps need to be taken to get the voicemail working?

Anyone noticed that AT&T MVNO is getting restrictions?

My Net10 AT&T is getting weird behaviors... Can't access the Internet, if it does, it keep redirecting to 1.2.3.50, and sometimes it tells you to sign into network...
How about straight talk? Anyone notice anything?

No issues on ST At&t for me.

None for me either (ST AT&T).

I'm having the same problem with my net10 at&t on my note II. On the net10 forums there a a few post about it but the mods are pming the people directly. You have to have more than five post to use the pm service. I've been on hold with net 10 for an hour and a half and I contacted them on the website.

Yes, I switched to Net10 last week and I started getting the "Sign into network AT&T" notification yesterday afternoon. I have GT-i9300 so its a BYOP issue, not a Nexus issue. As stated above its posted all over the Net10 forums but their customer service is being less than helpful. MMS has not worked at all since I switched from StraightTalk and now data is not working at all.
UPDATE:
After sitting on the phone for 2 hours with Net10 customer service here is what I know: They told me that since my current location (work) is not the same area as the zip code which I registered my phone (home) that the priority is downgraded on the towers. I asked to change my registered location but I was told that it is locked to the SIM and that I would have to cancel my current SIM plan and have them ship me a new one in 3-5 days. Ridiculous. However the following steps have seemed to work (have not lost data connectivity for ~an hour).
1) If you are not sure your APN settings are correct, double check them
NAME: net10
APN: tfdata
MMSC: http://mms-tf.net
MMS PROXY: mms3.tracfone.com
MMS PORT: 80
http://www.net10sim.com/support.php
Once you are confident you APN settings are correct DO NOT TOUCH THEM AGAIN. DO NOT EVEN OPEN APN SETTINGS. If you even open the APN menu it seems to trigger a reset of your network connection, even if you discard any changes. Once the connection resets you have no data ("Sign into network AT&T" message). I assume this has something to do with AT&T network authentication and/or queue priority.
2) Power your phone off and leave it off for at least 60 seconds (and take out the battery - why not, it cant hurt.) I believe this prolonged shutdown is long enough for all your connection info to be dropped from the tower.
3) Boot your phone back up and HOPEFULLY your connection will be properly restored.
Again, once your data connection is restored do not even browse into the APN settings as this appears to de-authenticate your data.

I called Net10 today the guy slipped and told me its a 1.5GB cap and he said they apologize because it suppose to refresh on March 1,2013... he refreshed my network and everything .. sad part im using a samsung galaxy note 2 and the only that works on the network is facebook now aint that a B*tc$... Forgot to say the Internet Doesn't work at all only thing working is Facebook Application and Google Voice other then that Nothing works.. I was on the phone for 1 hour before I got a Reference code to give it 24 hours and call back.. now Net10 really needs to shutdown for sucky customer and network service support... Atleast Tmobile and At&t pretended they cared. This started happening yesturday and I also get the sign into network as a notification.. Net10 really needs to pay their cell phone tower BILLS

I just had this issue on ST AT&T BYOP iPhone 5 factory unlocked stock 6.1.4.
Using the new tfdata APN that has been provided by ST since 6/15. The legacy att.mvno doesn't work at all any more for me.
Toggling airplane mode resolved the issue.

Like Andromed0 I have received the message twice this week.I am also using the newer APN ST settings. I have tried the "toggle Airplane Mode" and will see what happens.

If you're on Net10 with an AT&T sim card they say upfront that they throttle you at 1.5gb of data in any given month. I have yet to be throttled, but i'll probably hit 1.5gb this month with about a week left so we'll see what throttling is all about. Not sure if they just slow down the connection or completely cut it off, but I should know soon enough!

Be careful!

I hit some arbitrary limit before they had the 1.5gb cap. I was throttled and it stayed that way for months. I got jerked around by the phone support, email support and even their Facebook page staff for hours trying to get it lifted. It finally took a call to their "executive escalation" call center to resolve. I found that number on Howard Forums. The one that worked for me was 8008765753.

Usually extremely slow, ~4KB/s (kilobytes). Sometimes a little better, like ~10KB/s. Pretty useless.

Just posting some information in case it helps other people who might be searching like me...
The settings here from Net10 (scroll to "AT&T Network settings") result in no data:
http://www.net10wirelessphones.com/FAQ.html
The settings here from Net10 (click on "Phone Programming" and then "IF YOUR CARRIER IS AT&T") allow data, sms, and MMS:
http://net10sim.com/support.php
HOWEVER with these settings I still have intermittent data issues. For example:
Open Chrome, go to google.com = fast
Search for something = fast
Click the first result = hang, data connectivity lost (Chrome times out and says I am offline)
The settings here from xda behave the same as above:
http://forum.xda-developers.com/showpost.php?p=40188181&postcount=49
To be clear: sms, mms, and data "work" with the xda settings but I still have problems with data dropping. So I'm actually using the settings from "net10Sim.com" instead because they behave the same and require less editing.
I've put in a request with Net10 support to get real, valid, official APN settings but who knows if I'll really get anything.

Seeing the same thing on straight talk...
Now straight talk and net10 are sharing the tfdata APN settings... (Some straight people have been migrated to this tfdata, some are still on att.mvno)
Its really hit or miss... and seems to get better at night..
I can do a speed test and get 6 Mb down in Tulsa ok area, then not be able to load a web page.. I can tell when its acting up because the plus sign next to the H cycles.. On At&t and Net10 (At&t simm) for me that did not used to happened until just a week or so ago. Tmobile's + sign would cycle all the time. Now when I am having difficulty with a page loading I see it cycling.. When things are going "good" (fast page loads, consistent speedtest.net tests) + sign doesn't cycle at all.
Its frustrating to say the least..

I got this all the time, it means the phone can't connect to Google services... Usually also means internet is broken or to slow, when it happens to me nothing would load for several second. Switched to AT&T GoPhone and haven't had a single issue with that again.

It's only been the past month or so that it's been doing that, before that it was fine. I've seen on another thread that the apn settings have changed after the roll out of LTE or that I might need a new sim card possibly.

To be honest, mine started doing it in early August (although MMS has never worked) and I gave up after 4 hours on the phone with their tech support telling me it was an issue with my phone and not their problem. Switched to GoPhone and haven't had a single issue since.
Not sure if this is it either, but an AT&T wireless tech (I work in telecom, this is an actual tech that works on switches and tower sites), that the towers give priority to certain customers like AT&T post/pre paid accounts over MVNOs and if the equipment gets busy it will actually block "nonessential" services like data to lower grade APNs. He said they have seen traffic increases much more than expected from MVNOs in the last couple months... Take it for what's worth I guess.

[Q] Nexus 4 Straighttalk- New Att sim data and sync problem

I want to know if there is anyone else with the same problem as myself to try and troubleshoot, identify, and hopefully fix the following problem:
History:
I had an unlocked Nexus 4 on Straighttalk (on ATT's network by swapping out the sim from the nokia e5) from Feb. 2013- Dec. 2013 and had no problems with data or sync. In late December of 2013 I saw that Straighttalk was selling ATT micro sims again with 4G LTE compatibility so I decided to buy one (even though 4G LTE is not on the Nexus 4 without root) just in case I ever decided to upgrade phones. I activated the sim, updated the APN settings, and all data, mms, sms, and phone calls were working.
Problem:
Data was working (tested by using the browser and Facebook), but there were sync issues with all my google apps: gmail, keep, calendar, browser, etc. After a month of troublshooting, I've figured out that I get intermittent data signals, which is causing my google services to not sync properly. I have narrowed it down to a couple of things that are possibly causing the intermittent data:
1) The new APN from Straighttalk is not working properly for non-4G LTE phones
2) The new APN settings don't allow background data
3) The new sim card doesn't work properly with my phone
Solutions That I've Already Tried, and They Didn't Work:
- Tried every possible APN setting on the XDA Developers forums and the internet
- Tried using the "old" apn settings
- Tried using ATT's apn settings
- Factory reset
- Flashed .48 radio
- Tried to CM11 with the newest radios, older radios, and hybrid radios that enable 4G LTE
- Unroot, locked bootloader, and flashed factory image downloaded from the Google developer's website
A couple of other notes:
- I tried activating a Tmobile micro sim to test if it were my phone, but everything worked perfectly with Tmobile so I know it isn't the phone (I wish I had tried this before factory resetting, rooting, and going back). If I switched to the Tmobile sim, all my problems would be fixed, but my biggest problem is that the reception for phone calls was horrible so I want to stay on ATT's network
- When I turn airplane mode on and then off, all my data syncs properly. But who wants to manually sync every time they unlock their phone? At my job replying to emails in a timely manner is extremely important so my data not syncing properly is not ideal.
- Sometimes when I unlock my phone, the data tile in the swipe down menu is orange. Indicating a bad connection
- All my phone calls, sms, and mms work fine
- When I unlock my phone and open the web browser, it sometimes takes a while to start loading the web page. Similarly, when I manually load my email (in the gmail app by swiping down) it takes longer than normal.
- When I send an email, it takes a while to actually send
- With this new ATT micro sim, the network is no longer called "Home" (like it was with the other sim), it now has "AT&T". I'm guessing this has something to do with me not being able to switch back to the old APN settings.
My current APN Settings are:
Name: Straighttalk ATT
apn: tfdata
Port: 80
MMSC: (insert new straighttalk mmsc, I'm not allowed to post urls and this is a url I guess)
MMS proxy: 66.209.11.33
MMS Port: 80
APN Type: default,supl,mms,admin,internet,hipri
I'm running android 4.4.2 with the .98 radio, or in other words simply stock android.
Ookla Speedtest: 5.25/1.13 mbps and 160ms ping. It does lag when doing the upload portion of the test (i don't know if that's significant)
And everything else is left on default. If there is anyone else with the same problem let me know and I'd be glad to troubleshoot and if there is anyone that would like to help me with troubleshooting it would be greatly appreciated. Thanks.

I activated the sim, updated the APN settings, and all data, mms, sms, and phone calls were working.
Problem:
Data was working (tested by using the browser and Facebook), but there were sync issues with all my google apps: gmail, keep, calendar, browser, etc. After a month of troublshooting, I've figured out that I get intermittent data signals, which is causing my google services to not sync properly. I have narrowed it down to a couple of things that are possibly causing the intermittent data:
1) The new APN from Straighttalk is not working properly for non-4G LTE phones
2) The new APN settings don't allow background data
3) The new sim card doesn't work properly with my phone
Solutions That I've Already Tried, and They Didn't Work:
- Tried every possible APN setting on the XDA Developers forums and the internet
- Tried using the "old" apn settings
- Tried using ATT's apn settings
- Factory reset
- Flashed .48 radio
- Tried to CM11 with the newest radios, older radios, and hybrid radios that enable 4G LTE
- Unroot, locked bootloader, and flashed factory image downloaded from the Google developer's website
A couple of other notes:
- I tried activating a Tmobile micro sim to test if it were my phone, but everything worked perfectly with Tmobile so I know it isn't the phone (I wish I had tried this before factory resetting, rooting, and going back). If I switched to the Tmobile sim, all my problems would be fixed, but my biggest problem is that the reception for phone calls was horrible so I want to stay on ATT's network
- When I turn airplane mode on and then off, all my data syncs properly. But who wants to manually sync every time they unlock their phone? At my job replying to emails in a timely manner is extremely important so my data not syncing properly is not ideal.
- Sometimes when I unlock my phone, the data tile in the swipe down menu is orange. Indicating a bad connection
- All my phone calls, sms, and mms work fine
- When I unlock my phone and open the web browser, it sometimes takes a while to start loading the web page. Similarly, when I manually load my email (in the gmail app by swiping down) it takes longer than normal.
- When I send an email, it takes a while to actually send
- With this new ATT micro sim, the network is no longer called "Home" (like it was with the other sim), it now has "AT&T". I'm guessing this has something to do with me not being able to switch back to the old APN settings.
My current APN Settings are:
Name: Straighttalk ATT
apn: tfdata
Port: 80
MMSC: (insert new straighttalk mmsc, I'm not allowed to post urls and this is a url I guess)
MMS proxy: 66.209.11.33
MMS Port: 80
APN Type: default,supl,mms,admin,internet,hipri
I'm running android 4.4.2 with the .98 radio, or in other words simply stock android.
Ookla Speedtest: 5.25/1.13 mbps and 160ms ping. It does lag when doing the upload portion of the test (i don't know if that's significant)
And everything else is left on default. If there is anyone else with the same problem let me know and I'd be glad to troubleshoot and if there is anyone that would like to help me with troubleshooting it would be greatly appreciated. Thanks.

I have the exact same issue as you, only on a Nexus 5. I had a 2 year old StraightTalk Sim in my Nexus 5 with no sync issues at all. I ordered a new Sim card from Straight talk to get LTE on AT&T. Since using popping in the new Sim Card I experience sync issues with Gmail when the phone screen goes into sleep mode. If the phone screen is on and I send myself an email from a secondary account, it appears immediatly on my phone. As soon as my screen goes to sleep, sync stops working.
On my old StraightTalk Sim, I used att.mvno for APN settings. On the new StraightTalk SIM I use tfdata for APN Setting. My new StraightTalk APN settings are similar to yours except for APN Type. I'm using default,mms,supl,agps,fota,dun,hipri,entitle as instructed on Android Central in these screenshots - forums.androidcentral.com/google-nexus-5/334715-straight-talk-lte-t-sim-nexus-5-sweet-2.html
Called straighttalk customer service and they told me if I swapped Sims I needed to delete the old StraightTalk APN and re-add it back. Didn't fix my problem.

I experience and observe the same situation. I too tried to go back to a ST ATT sim w/ an att.mvno APN. I had an old sim card I hadn't used that had instructions saying use att.mvno for data. I transferred my number to it online but the final instructions said to use tfdata. I guess all AT&T sims going forward now activate under tfdata for data.
When u tested the T-Mobile sim, was it a straight talk sim, a postpaid sim, or a T-Mobile mvno sim?

After days of research it seems it is Fast Dormancy that is the culprit. Some carriers support it and others do not. Some phones have it enabled by default and some do not. It looks like the Nexus 5 has it enabled by default without a way to disable it...unless you root. These posts outline the issue and seems to offer a solution if you're willing to root and change build.prop.

A straight talk sim (using T-mobile's network) worked perfectly fine for me. In the end I switched away from ST and I got added to a friend's tmobile plan and saved a ton of money and I haven't had a problem with syncing since then. It is obvious an APN issue from Straighttalk, unfortunately.

I kinda want to avoid T-Mobile coverage so I did some back to basics tinkering and got my phones notification delay down to 3 minutes. I deleted all the pre-set APNs and created a new one using STs websites recommendation. The only difference from the previous APNs was I left the APN type field blank. No default,supl,mms. Surprisingly data worked, as well as MMS. Then I installed push notification fixer and changed the poll time. I put mobile heartbeat to 2 mins, and WiFi heartbeat to 1 min. I restarted the phone and for the past couple of days my notifications have been coming in w/in 3 mins. It's not the most instantaneous but it works for me.

I wanted to report back since I was experiencing this same issue on a Nexus 5 on Straight Talk AT&T compatible 4G SIM. I originally had a non-4G AT&T compaitible SIM from Straight Talk (for the past 2 years) using APN type: att.mvno in the APN settings (other settings were exactly what Straight Talk suggested on their website). This original sim was a full-sized sim used in a Galaxy S (original model) with no data issues whatsoever. I purchased a Nexus 5, cut this sim into a micro sim and expererienced NO data issues on the Nexus 5.
After my current minutes ran out on this sim, I ordered a new Straight Talk AT&T sim card because the new ones support 4G. When I popped the Straight Talk AT&T 4g Sim into my Nexus 5 I had to change the APN type from att.mvno to tfdata to get data to work. I INSTANTLY started having issues for the entire month of service noticing that my signal bars were orange 90% of the time I checked my signal. I tried numerous suggestions (factory reset, delete/readd APN, installed Push Notification Fix and Data Connection Fix apps and chose 3G instead of LTE in data settings - which seemed to work but only for a day before reverting back to data issues).
I'm now at the end of the month on my 4G ATT Straight Talk sim and with 1 week to go I decided to add 1 month of service to my original Straight Talk ATT sim (which is 2 years old and using att.mvno for APN type). As soon as I popped the old non-4G ATT Straight Talk sim card into my Nexus all data issues were resolved. I removed all the "data fix" apps and changed my APN type to att.mvno. I've been using the non 4G ATT Straightalk Sim card for 3 days in my Nexus 5 with no issues at all. Signal bars are always white and my google services sync instantly when a new email, Google Voice text, calendar event come in. Of course, I do not have 4G but at least I have pretty fast hspa speeds - which are faster and more prevalent in my area than T-mobile.
I can only speculate but there was a short span of time that ATT stopped allowing STraight talk to seel their sims. When they started allowing stratight talk to sell their sims again this is when STratight talk started switching everyone to tfdata for apn type. I suspect that ATT has increased the TCP idle time for MVNO's so they dont hammer the ATT network and affect direct ATT customers - but like I said that's just this guys opinion. I hope straight talk fixes this issue for those folks using ATT 4G sims but in the meantime, if you have an older sim, smoke em while you got em.

Op said he tried all apns on xda. I suggest this, keep the tfdata apn the same as straight talk recommends, but make the apn tfdata 1. All else the same. The only time I get delayed notifications is on Miui on wifi. Hope it helps.
