Hello everyone. Been wrestling with this all day. I purchased a barely used samsung galaxy tab 8.9 AT&T 4G LTE. It works fine with wifi, but I want to use it on my worksite where there is decent signal, but no wifi. Bought an AT&T SIM card, and put it in. I have full bars (signal), but no internet access. I have packet data turned off, as some forums have indicated this could fix it, but to no avail. With wifi turned off, the tablet status still says mobile network disconnected. Anyone have any ideas of what I could try? Thanks for any help.
EDIT: With packet data turned on, AT&T's data tracking widget says initializing, then goes to connection failed. With packet data off, it shows appropriate data usage (0mb at this point) and displays signal, but it still says no internet connection.
Did you get the right plan provisioned for the SIM? The Tab 8.9 is configured to use the "Broadband" APN by default so if you're not provisioned for that it won't work.
You need a data plan and a lte sim.

Just flashed to CM 7 and everything work great except mobile data.
It is able to get edge data, but when set to allow 3g data, the phone keeps switching between 3g and H, and never locks on a connection (the icons stay grey).
Any suggestions?
Thanks in advance!
Check your APN settings.
It is currently set to epc.tmobile.com
I tired internet2.voicestream.com before by editing the existing APN and swapping out the APN line, however, that had no effect.
Is that the correct process? or even the correct address?
So, I left the APN the same, turned off wifi, and let it try to connect to 3g the rest of the night.
After an unknown amount if time, but less than 5 hours, I was once again connected.
I guess the phone needed longer to reestablish the 3g connection.
I put in CM 9 in my old tab 7 and loved the performance so much i wanted to start using it again.
Was using it wifi only.
Got a month of prepaid data from AT&T.
No problem with connection to network but there is no data connection.
Has anybody seen something like this when trying to re-establish service with carrier? or just with the symptom of solid connection to network with no data connection.
I thought it would be modem file so I will try some others, but I should have the right one in the build.
I will be getting a new SIM in case it an AT&T issue (ugh), but I need time to drop by store (ugh).
Did a complete reset. Clean install and the APN are right.
Mobile Network apps (Kabits) shows cell connected nornally, just no data.
Any thoughts??
thanks much
Post your apn here?

I hope this is in the proper forum and hopefully the question has not been answered yet. I did a search and have found some threads but not this exact question.
So anyway...I have a Rogers (Canada) HTC One M7 running 4.4.2 and HTC Sense 6.0,
Lately I have been roaming in the USA and have incurred roaming charges even though I set my Data Roaming setting to Off (no check mark). It seems to only happen when I am roaming. Basically this is what happens.
The Data Roaming Setting is set to Off all the time.
I go into the US and lose data connection as I start to roam. This is fine.
If I turn off Mobile Data and then later turn it back on, I get the "You are roaming and incur charges..." pop up box.
The only options are OK or Cancel
Choosing Cancel keeps the Mobile Data Off
Choosing OK turns ON Mobile Data and the Data Roaming setting is suddenly set to ON (there is a check mark where previously there wasn't) and I now incur charges.
Is this by design? Shouldn't the Data Roaming setting stay off, even if you turn on/off the Mobile Data? I am not sure if this is a Phone Issue, and Android issue (OS or corrupted OS) or a Rogers (cell provider) issue or a Roaming (cell provider) issue.
I am hoping someone can enlighten me on this behaviour.
Thanks in advance.

I guess i am having the reverse effect to your problem, my data roaming keeps switching off.
With data roaming enabled, and network selection on automatic. Whenever I am in a no signal area with my home network provider, the phone should automatically roam on a partner network for mobile network and data network. (I can confirm this works when tested on a few Samsung phones). However on my HTC, the mobile network roaming works (calls and text) but data roaming does not work. It connects momentarily then disconnects and stays disconnected and wont re-enable until a reboot. If i manually select a network (either home network or roaming network) and then restart the phone, the mobile data will stay enabled. But as soon as there is a switch between home or roaming network then the data disconnects and cant reconnect until the next reboot.
I was wondering if this could be a hardware limitation or software limitation.

I personally don't think it is a hardware issue, although it may be a software bug and an issue with the roaming provider. I believe that the data roaming setting gets "reset" once the phone mobile data setting is turned back on on a foreign network. I think that the HTC "sees" a foreign network and does not know what to do so it either gets the setting from the roaming provider or just defaults to a set setting.
In my case, I had lots of support calls with Rogers and according to them, my data roaming settings are probably resetting based on the roaming provider when the mobile data setting is turned back on. I actually video recorded what happens and sent it to Rogers when I was roaming. Once they saw it, they told me that any unintentional roaming charges will be credited back.
They did not tell me if it was a software issue or a roaming issue. However, I also tried the same setting using an old iPhone4S and a Samsung Galaxy S3 and both worked fine under the same conditions. That is, the settings were retained.
HI all,
On february 16 my provider network SFR (French in Paris) had some issues, I lost my gsm and 4G and since I can't turn on 4G and Wi-Fi on my HTC at the same time as I used to do before, now the 4G icon disappear when the Wi-Fi is turned on and I can read " Use my data plan when Wi-Fi isn't available" instead of "connected".
It seems that the 4G is in sleep mode, the icon comes again and data "connected" if I receive or send a MMS then disappear again.
If the wi-fi is turned off, I have the data "connected" with the 4G icon, as usual.
I have reset the SFR apn, still same, I have contacted their support, they say that it's normal for a smartphone to use Wi-Fi and not 4G all together, but I did when i wanted !
Now I can't, is any of u had this problem, know the cause and how to solve it?
Thank u in advance.
Do you have an option of automitically connect to 4G when wi-fi is poor turned on? It is in wi-fi's advanced options
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...
