Hello folks,
Galaxy S4, Play Edition, currently rooted and AOSP 7.1.2 installed.
I rarely used data on this phone and never since I installed the ROM. Lately, I needed the data often and I noticed that I do not get the data on this ROM. I confirmed with the carrier about the APN settings (Airvoice Wireless, att MVNO). The carrier reset data from their end. I tried manual APN entry but none worked.
Searching on the web led to various ideas, like reset network settings, airplane mode on/off etc etc. Tried everything, no change in the status quo. I am at loss on what is the problem. I tried the SIM in my wife's phone (HTC One X, Kitkat) and it worked without any issue.
I could not figure out PDA, CSS but the baseband version is I9505GUEUDNL3, in case if it needs an update.
I checked the thread (https://forum.xda-developers.com/galaxy-s4/general/ref-galaxy-s4-i9505-modems-bootloaders-t3315987) over and over but didn't understand what/how this stuff is worked out.
I am really going nuts and I do not want to pony up for a new phone at this moment.
Any help is appreciated.
Flash back to a stock ROM and check for data connectivity. If everything works, it's a ROM issue rather than being a hardware issue.
The issue seems to be related to the ROM.
I restored to 5.0 (LRX21P.S012.141205) and the data works flawlessly.

I have been running Nightlies of CM11 everyday as they are released and normally I have no problems. One of them must have tripped something. Wherever "Sprint" is supposed to be--bottom of notification panel and under the signal in the quick setting panel--it says "Roaming Indicator Off." I normally wouldn't mind but with it is the inability to send MMS or connect to LTE.
I've flashed various APN zips to try to fix it that way to no avail. I've tried manually entering the apns and still nothing. I set the phone back to stock using ODIN and LTE and data worked fine. I rooted it again and install the pre unified build of JFLTESPR and data and lte worked, then when i wiped and installed M8 again came the roaming indicator off. I'm not sure what the issue is, but I really would like to get the kinks worked out so I can have LTE again.
It a problem with the ROM that has to be fixed by the developer.
Problem is fixed, it had to do with the the rom not asking for the pin to my sim card. I flashed an older build and used it to remove the need for the sim pin and then reflashed to the most current build.
I just upgraded to Lollipop and lost LTE. I have EHRPD 3G only.
I am rooted and on Extreme Syndicate 5.0 Lollipop.
I have tried the usual items found in Google:
1) Removed SIM, rebooted. Put back SIM
2) Checked LTE settings under mobile networks (Global, also tried CDMA/ LTE)
3) Checked APN (vzwinternet, internet and VZWINTERNET)
4) Tried basic toggling of airplane mode, data, etc.
I am trying to avoid going back to kitkat stock and working back to lollipop.
I am hearing that a new SIM may be required but I have not gone that route yet and would like to resolve right away rather than taking a day for a SIM to ship to me.
Any help is appreciated.
Have you factory reset the phone after the update? It would be something to try.

I tried numerous things. Right now my LTE has come back however things are kind of strange when I reboot, but at least ultimately end up working. I have a new SIM to throw in there when I lose things entirely again. I'm now sort of convinced that the problem is the SIM as I have tried a few different ROM's including stock unrooted KitKat and data always acts the same. I'm now on 5.0 and it's again the same.
Hello, after upgrade to 5.0 my s5 verizon, i lost 4g, but on 4.4 it worked fine in russia
First off I'm using an unlocked S5 on straight talk's LTE network, have been for about 9 months with no problems. I've talked to support twice and they reactivated networks and all that good stuff, and when none of that worked sent me a new sim, which I have just activated and it still didn't fix my problem - so I'm finally bringing my issue here.
Last week I decided to update from phoenix rom oc4 (I think it was oc4) to optimal rom og5 (15-5). Anyway I was hasty in flashing and messed up, so just went back to stock ncg > root > full wipe > flash firmware, rom, kernel, firmware again just to be safe. The rom works fine except I seem to have lost my data connection. The 4G icon still shows, but it's not filled in - as you can see in the screenshots. To make it even more strange, when I check the network and sim card in apps like Advance Signal Status and Sim Manager, I still seem to be getting a connection to 4G but there is just no data flowing. The only error I can see is in phone info, when I run a ping test, I get PingIpAddr: Fail: IP addr not reachable which you can also see in the screenshots. It would appear this is my problem but I don't know where to go from here. I'm going to start flashing different versions of modems, starting with oc4 to see if that helps. Then I'll probably try different roms, but I've flashed other roms trying to fix this and even restored the backup to when it worked and it still didn't fix my problem. Did I wipe my IP address or something maybe? I am in CDMA/LTE mode, and the vzwinternet apn is selected.
For starters try to put the apn settings for your carrier and if not sure call them and ask them to email you the setting
I fixed it, went back to stock ncg instead of ni2 and that worked. Weird.

Hi, I'm having a very perplexing issue. For the last few months I have been running cm13 on my phone but recently it decided to not revive/send texts or calls but still got 4g and signal. I hadn't updated the rom or anything so that wasn't the fault. Looking at the sim card info in the setting it says it's in service and everything, but says the "cellular network state: Disconnected". I've reflashed to a touchwiz rom and everything worked fine. So far I've tried different cm roms clean and dirty flashing, flashing just the modem on to the cm roms, restoring from old backup before all this, replacing the sim card. For awhile I though it was the APN settings weren't right, but the cm apn settings matched the TouchWiz ones. I've also tried different unbootlocking methods, didn't help. Worked with an unlocked bootloader running touchwiz. My brother has been running the same phone and rom I was and hasn't had any issues. I'm out of ideas on what's causing this right now, hoping some can help.
Had something similar happen. Try changing the APNS till you get a single
Changing preferred networks might help too
