AT&T Tab will no longer connect to AT&T data - Galaxy Tab Q&A, Help & Troubleshooting

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?

Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.

Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.

Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.

I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.

Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.

It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?

Yes, I have voice and 3g data by ising a sim from my old android phone.

I am not roaming, I am home. arrrggh!!!

For some strange reason my phone thinks I am roaming when i'm not and keeps warning me about additional data charges everytime I check my email. I tried to choose my provider from the dropdown list but there are no Canadian providers listed..... and yes I am in Canada. I don't mind the warning so much but it also won't connect automatically and check my email. How can I fix this?
thanks.
Hi Dongetti
Welcome to XDA-Dev
Your question is fine, but it would be better placed in the regular Kaiser forum as it does not related to Upgrading/Development.
I will move it to the Kaiser Forum with an expiring (6hrs) redirect from the Kaiser upgrading Forum. So by tomorrow you will know where to look for it.
Cheers
Mike
Where in canada do you reside? are you close to a border of some kind?
Roam?
I have that same (problem) with my 8525, after I got the Tilt I added a second line and even though the phones have shared minutes and are billed together the Hermes still thinks it's roaming when the Tilt doesn't.
I called the carrier and she told me it was a fix on their end and that I would have to call back to customer service, it's not the phone or ROM.

I'm running Dutty's WM6 on AT&T Tilt, in Toronto on Rogers, works fine.
Thanks for the replies....
By the way, i'm running Sleuth 1.0 on AT&T tilt and no I don't live anywhere near the US border.
I'm having the same damn problem. In the morning there's a stupid triangle up on my today screen. Is that what you are talking about?
No my problem is this:
go to control panel (start -> settings ).
Then go to the connections page.
Then tap connection setup, it will give you a list of Countries to choose from and and then a list of providers below that. The problem is that my provider is not listed and that makes the phone think i'm roaming when I am not. Even though I enter my connection settings manually it won't connect 'automatically' to check my email. Therefore, I have to go in and send/receive manually to see if I got any new mail and it always warns me that i'm roaming(when i'm not) and checking my email may result in data charges.
That's not your problem, you can always manually configure your connection settings to your carrier's.
The problem is that your phone think's it's roaming based on the wireless signals from the tower...
dongetti, probably you're using fido sim?
if that's the case, then it's not fixable. As you know since Robbers acquired Fido, they have integrated the tower. But for some reason, the code for fido was being left in your sim (they don't change it to Robber's code). No other choice than to use Rogers signal, since that's the only one available now anyway.
Are there roaming charges if it is roaming between rogers and fido? even after the merger?

No there wont be any roaming charges.. for more info on this check the fido section in the howard forums website, also you can check with fido's customer service about this issue
i've been with fido for about 3 years now with an unlocked phone right from the start and every phone i've had has the little roaming symbol at the top, but i've never seen any roaming charges on it yet

Data connection isn't starting

Hi. I just bought a new galaxy s from vodafone, but when i tried to use a 3g data connection it just won't work. it works fine with wi-fi connection but if i turn that off (or if i don't use it at all) the phone just won't connect to the internet. i've double checked the apn settings...is there an option to turn the data connection on and i'm just not seeing it? please help...
sometimes it helps to restart the phone
or switch it to airplane mode then back
Did that
i've read other posts for other type of connection problems and i did what u said...nothing...it just doesn't even try to connect...
do you have any other SIM card from friends/family that you can try?
just wondering if it's related to your SIM account, or if it's defective phone
if it is working over wifi there is still something wrong with apn settings or your sim card.. i doubt it is the phone itself.. or you are in an area with no 3g edge.. or wrong phone ie t mobile vibrant on bell or att network

thanks for the update
glad to hear you are back online
yes phone companies do mess up very often in our accounts
just yesterday i was complaining to my phone company about something similar

[Q] [q] unlocked at&t gn3 on metro pcs trouble trouble trouble

As stated in the title/subject line, I have an unlocked AT+T Note 3 that I'm using with Metro PCS. I'm using the SIM card which was previously in my Metro PCS Galaxy S3.
Now, 1 week after I began utilizing this phone I moved across town and for the past month I've assumed that was in a 'NON Metro' area... rather there just wasn't a good signal here. However.... it turns out my neighbor has Metro and low & behold his service is excellent! I was shocked at how he's always got a 4G signal when I'm not even able to connect to the internet AT ALL. And boy have I tried everything! When I initially moved in, my ISP dropped the ball and failed to transfer my internet service.... it took almost 2 weeks for them to connect a coaxial from the BOTTOM of the telephone pole to the coaxial from my house... anyway, I was so desperate to get online I tried absolutely everything.... FAIL! Although.... on ONE occasion I did have a website page load halfway then 'timeout'.
I've manually and automatically input APN settings. The apn settings are the T-Mobile APN settings that automatically generated when sim was inserted (I dunno if that is even the correct term to describe APN settings...).
What am I missing? Or not doing? Should I be changing anything via hidden menu? This is making me insane..... any advice would be truly appreciated!
Thanks ..... in advance from the Crazy Nurse....
Try these APN settings
mcc="310"
mnc="260"
extraid="6D"
apn="fast.metropcs.com"
user=""
password=""
authtype="0"

I'm not seeing "EXTRAID" line/entry slot that is listed on the APN settings you posted.
Here are my settings... I'm not currently using this APN because I don't think they're right. I'm using the T-Mobile...
*edited to add this question: do i also need to change some settings via hidden menu?
Thank you very much for your help BTW!

Was your S3 an unlocked model like your Note 3 or was it the metropcs version, metro had the white one which is a cdma/lte and later on they had the black/blue which is gsm/lte .
On your note 3 did your data work before you moved? Do you currently have talk and regular text working?
If data was working before you moved try going to your settings, connections, more networks, mobile networks and have both mobile data and data roaming checked on next go to network operators, click on default setup and then click on automatic if its on automatic already then click on manual, it should take a couple of minutes after that choose T-Mobile and after all that turn off and then back on. Hopefully that's all you have to do because the next step would be call customer service and have your line refreshed and then do the steps again.
@440bro 's apn is one of the other apn's you can also tryout.
yup...
Yeah... I don't have that line 'extraid'...
Neighbors S3 is an unlocked AT&T as well.... she gets exceptional service...
I got pretty good data before I moved... and yes, talk & text work... however.... If my phone isn't in just the right spot it'll roll directly to voicemail without ringing... and on rare occasions it'll say 'no mobile networks' when I'm texting..... If I wave the phone around in the air it'll send the text. (if anyone saw me flapping my arms around they'd probably call to have me committed, lol)...
Also, when i go in under the operator settings as you suggested, I'm unable to change it to manual... rather, when i select 'manual' it states that it's searching but after a few minutes... after nothing happens it'll put itself back to 'automatic' ...
Thank you very much for your help...hope I can figure it out !

Have you tired a Hard Rest?
I had a unlocked At&t note 2 that started doing the same as your note 3 but I was flashing different rom's and mistakenly flashed a different modem and it went down hill from there, eventually I sold it for parts.
I recently got an employee line from metro and nothing was working, no talk/text/data but I contact customer service and asked them to refreshed my line from there end and a couple of hours later I was up and going. That might help you too.
The very last thing you can do is to try a new sim card which costs $10.00+ tax. Depending on the store you go to they might want to charge you to activate it but just let them know that you can activated for free by calling customer service.

S6 Active on T-Mobile roaming data not working

Wondering if anyone can help me out. I've already spent hours on the phone with tmobile and they can't seem to solve it.
I've had this problem ongoing since getting this phone. Basically I get no data roaming. Places Ive tried: Canada (several cities in BC as well as Quebec and Ontario), UAE, Bahamas. I spend a lot of time in Canada so its a real issue. Things I have tried:
- Factory reset
- Upgrade to 5.1.1 using Odin.
- Try sim card in friend's phone (4G works no problem in Canada)
- A bunch of other stuff I don't remember
Symptoms:
- About 50% of the time the phone works for calls and text
- The rest of the time it says "emergancy calls only". Restarting the phone immediately restores ability to make calls/send text. This happens regardless of signal strength.
- Data connection never works. Only time I got 4G was the very first time I entered canada with this phone. . Restarting the phone would make it connect to 4G for about 1-2 minutes before it would lose data connection. Restarting the phone would bring it back. After about half a day the phone completely lost ability to make data connection and has never been able to get data connection internationally since then.
- Sometimes I get this message: "you have lost data connectivity because you left your home network with data roaming turned off". Data roaming is definitely turned on. I've enabled in settings and also via #RON# short code.

This sounds like a config issue to me. the random drops to emergency seems to be issues with roaming not being set up right. It sounds like your APNs are not setup correctly or something. have you gotten any info from t-mobile on Roaming APNs? i'm not sure if it needs to be adjusted for roaming or not.

Yeh thats what it seemed like to me as well but I went over the APN settings with them on several occasions. I also looked them up online. Everything seems correct. The only thing they had me change was APN roaming protocol from IPv6 to IPv4/IPv6.
Dial *#*#4636#*#* (on stock dialer), in Device Information try to change network settings to LTE/WCDMA.
What are your APN settings? Provide info about all fields.
Did u ever solve this issue ? I'm having the same problem...

Question Data not connecting on ATT since "3G switchoff"

So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now. All my bars went to 0 with an x on it and I couldn't do anything on the phone. I went to an ATT store, got them to give me a new activated sim and I put it in my phone and all my bars came back.
My phone says VoLTE again too by the signal bar area. I also tested a text and it went through fine. I received a phone call and while it works fine, it sounds like junk now. Like it is no longer actually using VoLTE like it always has. My phone doesnt seem to have any data however, when it should have LTE just fine. I also cannot make any calls, even though it says VoLTE on the phone, it just re-routes to ATT customer service instead of going through with the call.
When I go into the network area in settings it says no IP address either. I looked and my APN is set to nxtgenphone, Preferred Network Type selected on LTE. Before ATT deactivated my sim card LTE has always worked fine, and LTE should still work fine. It is only the 3G network being shut down. Also given the fact I have the VoLTE icon the phone is apparently connecting somewhat to an LTE network.
So does anyone know how to fix settings to get data working again? Is it just an APN that needs to change? What is everyone else doing with the network shutdown and has anyone else had issues like this?
I had the exact same issue, your issue is in fact APN settings I'm having them as well. Try deleting your current APN and putting in a new one. Once I got a new sim my APN reset I could call but no data and no text. I have half of the APN information in place and have data and basic text, but once I input the MMS port the APN data disappears still trying to figure that out. Not sure if anything I typed is helpful but at least you know your not alone with a mi11 on ATT and it can work

Thanks for the reply. I tried deleting the MMS port and also the proxy just now and data didnt come back. I will try searching around for more APN info for how phones are supposed to connect now and see if I can find anything.
It looks like from what I could find that it is due to an IMEI whitelist ATT has, blocking data connection on any device not in their whitelist. The solution seems to be to root the phone and change your IMEI to a whitelisted model.
While my phone is rooted my IMEI is not cloned I definitely would not share my IMEI with ATT. When I got my sim card yesterday I had the attendant activate but I did not provide my phone so he did not get the IMEI from my phone. If you got a sim and they input your IMEI that could be a problem possibly. Just a suggestion to try and get a sim activated at a store without your phone.
I had also heard that most ATT MVNOs were not having the device whitelist forced on them yet, so I went and tried 2 different ones yesterday. Both failed to get the phone working on their network with their sims.
Before I went through the hassle of rooting (and most likely losing payments) I tried ATT again anyway. I used their online customer service chat and the first person I chatted with said he could help me with the lte data problem and the IMEI issue. I was skeptical, but he actually did fix it all up. He just needed my sim ICCID and my phones IMEI1 and he submitted the info to their backend people for adding to their system. It took almost an hour and a half for it to get added, but overall it was a pretty painless process and I was browing the web most of the time while waiting in chat. I now have LTE data again, VoLTE again, and "5G" too (which ATT 5G is really just one or two more features than normal LTE and is no faster in speed and uses LTE data bands). I attached a screenshot showing the data and VoLTE working on my phone. The first signal is ATT, the second is TMobile (which has always worked and never had an issue, their 3G network shutdown is going on for another 4-5 months)

Happy you are back up and running and I'm glad that you found someone at ATT to do the fairly easy work of getting your IMEI cleared. Lots of people have been worried about devices not working on ATT because of this whitelist issue glad to see there are workarounds just wish ATT didn't make it so convoluted.
