Took my first international trip since getting the 6P. I called to add international services. In the Bahamas, I can get voice, but no data.
I spent a hour hour on the phone with VZW, but they were unable to assist. Took the SIM out, rebooted, checked a dozen settings - nothing.
This is the first negative experience I've had with the phone.
Anyone else have experience with this, or have any thoughts/ideas?
I have had a similar problem anytime I am away from my home network. Two observations from me: (1) the phone does not give any indication on whether it's connected to a data network or not when roaming (all you see is the "R" symbol in the signal strength meter whether you have data or not) and (2) most of the time it doesn't connect automatically- if you toggle data roaming or airplane mode, it connects to data, but this disappears when handing off to the next tower.
This is clearly a bug- if I move my SIM from the 6P to my iPhone 6, i get continuous roaming data, so it's nothing to do with the provider. I wish there was a fix as it's a pain in the b**t.
Not very helpful I know, but you're not alone with this issue

Hey Everyone,
I am not certain how specific this issues is to my exact situation, so I am describing every related aspect that I can.
Details
Phone: HTC MT3G (3.5mm Jack version), rooted, running CM 6.1.0 RC1
Network: Wind Mobile (in Canada)
-- please indicate if any other details are needed for troubleshooting --
Issue
Wind mobile offers an unlimited plan that includes data, provided you stay within what they call their "Home Zone (ie the metropolitan area known as GTA, in my case). When travelling outside of the Home Zone, you enter an Away Zone. This is essentially roaming on Rogers network, using 2G (Edge) for data. This costs a lot and so naturally I don't want to roam.
Before the phone was rooted and upgraded, I had checked the box to in settings to disable data while roaming. I travelled in and out of the Home Zone and it worked as expected - that is, turning off the data connection as soon as the network switched from Home to Away. As expected, it re-enabled data upon re-entering the Home Zone.
Since rooting/updating, this functionality seems to have disappeared. I have the box checked, but as soon as I step into an Away Zone, it switches to 2G and starts using data whilest roaming. At first, I thought this might be because I performed the upgrade process in an away zone and as such, the phone would associate that with being "Home". However it keeps data across Home and Away (which negates that theory as "Home" should now be "Away" and data disabled.
I wiped and started again in a Home Zone, with no success.
So:
1) Is there something I am doing wrong, or a known way to remedy this issue?
If not,
2) Is there any way to disable 2G (similar to the way you can disable 3G for battery savings?) This would be an indirect way to solve the issue, as the only time 2G is used is when the phone is in an Away Zone.
Thanks for any advice and help you can provide!
Bump - any ideas?
There's been a lot of talk on XDA recently about fast dormancy on the Galaxy series and yesterday on the LG Optimus G. Apparently AT&T loves using FD on their network and it's causing many users issues from battery to reconnect issues on data.
There are a couple of threads on here particularly detailing a scenario whereby AT&T users will start on a phone call with their data connection active. After a small period of time (usually around 1 minute), the data connection will drop and will not reconnect (forced onto 2G) until you end the phone call. Users are able to fix this by going into *#*#4636#*#* and selecting WCDMA only.
My question is could it be possible that our devices have FD on by default and after a period of data inactivity (phone call) the phone is using FD to drop down to the lower level of cell service?
If so, how can we fix this?
Sorry to necro this thread, but I just went through a week of new (new as in not the normal Qualcomm WIFI data drop issue) data connectivity issues, on AT&T, here in the Twin Cities. I would not have data after being idle, after leaving WIFI, or after what I assume is a tower switch -- for about 5-10 minutes, then I'd get data for a little bit, then as soon as I idled I'd be back in bollocks. After trying EVERYTHING including getting my account reprovisioned, a new SIM, every ROM/kernel/baseband, etc., I walked into a T-Mobile and picked up a prepaid SIM. Everything works great.
What I noticed is when data is idle on AT&T you get HSPA:10 while on TMobile you get UMTS:3. When active on either network you get HSPA+:15.
Since, for me, the issue has gotten worse of the last week, I've concluded that AT&T changed something having to do with fast dormancy and it really messes with the N4. I did see similar symptoms on my iPhone 4, but they weren't quite as debilitating as on the N4.
Anyway, this is my long-winded reply of saying I agree with your original assessment of the problem, although you're referring specifically to a different symptom than I am (to the drop while on a call vs drop after idle).

I'm not on AT&T, but have the exact same symptoms. After having searched for a while and tried whatever I could (different radios, disabling hspap in the build.prop, enabling LTE, etc.), I concur with the conclusion that certain providers' Fast Dormancy settings don't work with the N4.
So has anyone got a fix? Disabling FD or even disabling HSPAP?
I've had this problem for a while now but it's starting to get extremely annoying. If I'm not connected to WiFi I will have no mobile data at all. I can still send texts or make a phone call but I can't go on the internet or receive MMS. I've tried at least 5 different APN settings and I've made sure that "Data Enabled" is checked but nothing works. When I contacted AT&T they said there is nothing they can do because it is not an AT&T device.

Maybe you should try again, but this time tell them you'll drop them like a hot potato if they don't give you the correct APN settings. They're doing false advertising by telling you just because it's not their device that they cannot help you. Oh really jerks? I'd ask them why the f you pay full price like everyone else then. Try playing rough, maybe you'll get a response. I'd answer you but I don't know AT&T's settings. I use T-Mobile.
After some research, it may be a problem on their end. They may have you set up for a non-smartphone data plan or HSPA or LTE, not HSPA+ data. Look at your statement and see what plan you're on. You can always call them and make sure you're set up with HSPA+. Tell them to die in a ditch if they refuse to service a paying customer.

I'm having a similar issue that seems to have started around 4-5 days ago. I'm in the Twin Cities area, btw, if that matters.
Prior to that, I was only the victim of the occasional data drop or ARP offload delayed-notification issue.
The problem usually, but not aways, occurs when I leave a WIFI area and get handed off to the cell towers. I get no data, but calls/SMS works fine. Anywhere from 5-15 minutes later, I will get mobile data again, but only briefly before it goes away again.
The issue can also occur when seemingly changing towers, or going from HSPA > HSPA+.
On occasion, when the problem is occuring, my cell bars will still show blue as google services don't know they've been disconnected, but when I attempt to access, for instance, gmail or GNow, I will get no connection. Finally the bars will turn grey as the phone attempts to (apparently) cycle the radio.
Oddly, I stopped into a retail store here locally and the gal said they were having data issues so I figured it'd be fixed. That was 5 days ago. 3 days ago I called customer care and logged a case. They've found no issues with their towers or my provisioning thus far.
I also switched out my SIM card. No change.
At this point I think I'm going to walk over to T-Mobile and try a prepaid SIM to see if it's the phone or really and truly something with AT&T's network.
I'll post a logcat here if anyone is interested but I couldn't find too much interesting within it.

I've been on the T-Mobile network now for about an hour and I have had ZERO of the aforementioned issues. The phone definitely handles leaving WIFI > HSPA better as well.
On a recent trip I made which took me outside my network's coverage area, I found that, on returning, my phone did not re-connect to the network. And, when I went to look at what might be wrong, I found that the "Mobile Networks" panel was missing from the Settings menu.
This problem was also reported by an S6 user here:
http://forum.xda-developers.com/galaxy-s6/help/mobile-networks-disappeared-settings-t3211167
Now, in my case, a reboot immediately restored the network connectivity and the settings panel, and all is well again. However, I was back inside the service area for most of a day before I realized the problem and did the reboot. So almost a day's worth of messages were delayed. This is obviously not a good thing.
In my case, my SIM is with US-Mobile, a T-Mobile MVNO. The trip was a drive outside the coverage area into Canada and then northern Maine. I mention that it was a drive to point out that the phone was not put into flight mode during a flight somewhere, it was simply moved out of my own network's coverage area. When I drove back, the phone bars did show service active again, but no data service. Simply toggling the "Mobile data" toggle in the pull-down, as well as toggling "Airplane mode" had no effect - on turning them back on, the voice bars came on, but not data service. When I eventually rebooted, the data service came back immediately.
My phone is the SM-G935FD, not rooted, running stock Samsung firmware, up-to-date G935FXXU1APEQ version. It is UAE firmware.
I'm reporting this here in the hope that someone knows some way of automating the re-start of the Mobile Networks system, so that folk don't lose a whole day of messages.
Or maybe a Samsung dev will read this and figure out what bug caused Mobile Networks to stop in the first place. Maybe this bug can be fixed, please?
I use MVNOs because I am on a tight budget. With MintSim and MetroPCS which use T-mobile I had a below average signal on this phone and with Boost which uses Sprint I had a dreadful signal. Currently I'm using a Verizon MVNO which has an excellent signal except for one issue. The signal will be great for a day then it will become poor. The signal strength will not return to previous strength unless I power the phone down for a minute and then turn it back on. Then the signal will be great for about a day again until it goes bad and I have to turn the phone off and on again.
I tried a factory reset which didn't help. Toggling airplane mode on and off doesn't help. Rebooting the phone instead of powering off doesn't help. Changing the preferred network type in settings doesn't help.
If I type *#*#4636#*#* and change the network from LTE/CDMD/UMTS (Auto PRL) to one where LTE is replaced by a different network and then switch back to LTE/CDMA/UMTS that restores the strong LTE signal but powering the phone on and off is faster.
I could change the APN settings with T-Mobile but with Verizon the APN settings are greyed out and there is no way to edit the current APN or add a new one.
Mobile Data Always Active is already enabled in developer options.
Does anybody know what I could do so the Verizon network strength doesn't eventually drop requiring shutting the phone off and turning it back on to refresh the network connection?
I have owned a lot of phones over the years but never one with signal issues like the PH-1. Essential support won't help because they escalated my ticket to RMA when I was still on T-Mobile. Since an RMA would provide me with a refurbished phone that somebody else probably returned due to the signal strength issues I would rather figure out how to get my current phone to work right with Verizon if that's possible.
When I went out I had no data despite the signal meter showing a strong signal. It turned out my phone had the wrong APN (Verizon instead of Trac Wireless) but unlike GSM carriers the APN settings are locked so TotalWireless (which is owned by Trac Phone) had to send my phone the correct APN. My data actually works now and so far the signal has been very strong but it's too early to say if the same signal problem I wrote about will pop up again since the APN was only corrected a few hours ago.
If nobody else has experienced a similar issue with the quality of the Verizon signal losing strength after the phone has been asleep for an extended period of time then maybe my phone is defective after all. I guess I'll just keep my fingers crossed that the signal still looks good when I wake up tomorrow.
