Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.
Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!
Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.
So here's the problem. I'm on a rooted Virgin Mobile galaxy s5. Sm-g900p. I just flashed exodus rom based on android 5.1.1. I can text and call but I can't connect to mobile data. I know its because I have no APN's. The entire APN list is blank. I would add them in manually but I can't edit APN's on 5.1.1. When I add them in and hit save, my APN list stays blank. It just says APN settings are not available for this user where the APN's should be. I also get a popup every so often saying "no APN's specified on this device". Does anybody know how to fix this?
Hello, I am trying to use D2G on the Ting's GSM network (which is T-mobile's network). I am running the cyanogenmod 7 rom (with gingerbread kernel, I think).
I followed band unlock procedures here:
https://docs.google.com/document/d/1l15c0hxwQFAh1e1ewVMe3QUy4d1Laa51C2WCmBizSxA/edit
After putting in the sim card from Ting, it connects to T-mobile's network and I am able to make calls and texts, which is great.
However, I am unable to use data over the network. Ting has its own apn settings, which I have tried to enter. But after I add the apn in apn settings, the page remains blank and I am unable to select the apn that I have added.
To get around this, I have tried replacing /system/etc/apns-conf.xml with one I created myself with Ting's info, reset apn to default and reboot. Unfortunately, the phone still isn't connecting to data, and the apn page in settings remains blank.
So does anyone know what I should do? Would flashing a different rom help, is this a cyanogenmod issue?
Thanks
Hey guys. I Bought an unlocked S7 SM-G930V. Insertted my iiNet Simcard(nano).
Then i rooted it through Sticky thread (https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039)
rooted it to G930VVRU4API3. Android Version 6.0.1
turned on mobile data, and inputted my APN details according to my phone network provider (iiNet) (https://iihelp.iinet.net.au/Troubleshooting_Mobile_Voice_for_Cannot_send_SMS_or_MMS)
Tried a few other APN combinations online such as using Optus's APN details(since iinet pretty much = Optus)
But i am still having MMS issues where i can't send/receive. But am able to use the net/make calls/SMS.
I re-enabled all the bloatware that i disabled by the disabler package pro.
My Question is (Please bear in mind that I have been sent an important image via MMS and i cant download it so i am avoiding anything that could clear that image from my text history)
1) Is it possible to insert my simcard into another phone and re-download the image that was sent to me already?
2) Any ideas? Would flashing to an incompatable ROM cause this?
=============EDIT/UPDATE
I inserted another sim card(nano), changed the APN settings to fit telstra's APN settings and now i can send/recieve MMS's(for that other number, and am unable to download the pic sent to me by my main simcard.
Call your carrier and ask them to text you the MMS settings, sounds like the ones you manually added are correct for Data but incorrect for MMS
So, let me explain the problem I had as context for my question.
I have a HTC M8 from Verizon that is totally unlocked (bootloader, SIM, etc) and rooted. I am running a recent version of LineageOS
My wife has a Samsung Galaxy S5 from Verizon that is rooted. She is running the latest available stock firmware from Verizon (with some bloat removed).
On the Verizon network with our Verizon SIM cards neither of us could edit APN settings.
We have been off contract for a while and just switched to Total Wireless.
I had 0 issues with my phone as the proper APN for Total Wireless was obviously loaded properly into my phone when I put in their SIM.
My wife OTOH was not able to get any internet access and upon examining her settings I noticed she lacked the newer TRACFONE.VZWENTP APN that my phone had.
I was not however able to edit her APN settings.
From everything I was finding online it seemed that the phone was clearly unlocked since the TW SIM worked to make/receive phone calls. Also it appeared people were stating that the presence of an APN is a function of the SIM and that if the APN wasn't there or I couldn't add it, then the SIM was the problem.
In the end I was able to install build.prop editor and make the following changes:
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
This allowed me to add an APN. I copied the settings from my HTC *exactly* (triple checked) and still no Internet.
Finally I chose the option "Reset to default" and it appeared that it deleted the APN I added and added another TRACFONE.VZWENTP that was just slightly different then what I had on my phone (it set the "Bearer" option to 'LTE' instead of 'unspecified'). Everything then worked.
This experience leaves me to believe the following:
1) The ability to edit the APNs is a function of the ROM, not the SIM, since I was able to edit with build.prop and then make the change.
If this is the case however, why would a custom ROM like LineageOS not have this unlocked by default???
2) The APN is actually stored in the SIM card.
This must be the case because when I "Reset to default" there was nowhere that it could have gotten these changed settings from other than the SIM card as it was unable to even reach out to the internet at the time (wifi was off).
This was all just such a hassle and there are hundreds of posts out there about people in similar situation who state they can't access their APN settings.
If my wife's phone wasn't rooted I would not have been able to use build.prop editor to make the APN editable and then I would never have been able to get internet. What could I have done in that situation?
Again - my issue was resolved, but I am trying to understand specifically how these things are controlled and unlocked - especially for someone who doesn't have root access to their phone.
Oh - I just wanted to add that I worked with Total Wireless over chat for close to an hour while I was researching this on my own.
I helped them out from the beginning by telling them that I thought the APN was the issue and the block head kept telling me that I needed to edit my APN settings.
When I continued to tell him they were greyed out and I couldn't do it he just kept repeating as if they have never experienced this before and there *must* be a way for me to edit my APN settings.
I haven't had a build on my HTC or my wife's G5 that I can remember where I have ever been able to edit them manually, so I would expect that grayed out APN settings are pretty standard. Ofc I may have had a total moron over chat (likely), but he seemed to be consulting either their internal KB or another associate - so the fact that it was so difficult for them to figure this out (in fact they never did, I did) and they never would likely have if my phone wasn't rooted is very perplexing to me as to the root problem.
