[Q] MMS and 4G is broken. Help! - General Questions and Answers

I am running CM12 on the Desire 816 from Virgin Mobile. I can use 3G and recieve calls and SMS messages. 4G doesn't work at all. I've tried going to the secret menu and trying all the different mobile network options that have LTE in the name and no dice. I've tried flashing this and when I do that I don't get a data connection at all. I really don't know what to do here. It was working fine on CM12 until I had to reset my phone yesterday.

You need to edit a certain APN file in the system directory. I'm not sure which one, as I'm stuck on Kitkat, but maybe that will help your research.

What do you mean by 'update my mobile settings'? What exactly did you do?
I cannot send MMS either and I have tried everything I can think of. APN's have been deleted and re-entered etc. Nothing works
I also have the same issue as you guys. From what I've read, the issue has to do with ICS's MSS not functioning properly on 3G, but working on Wifi. I'm not quite sure if the issue is related to the T-Mobile OTA version I installed and my current carrier in Canada, or if it's an issue plagued by all devices running the T-Mobile OTA.
I noticed that under APN settings there is a new option called 'Carrier' - Does this need to be configured for something special (LTE or eHRPD) for MMS on a european 3G GSM phone?
Still no luck getting MMS to work :-(
Working on some carriers
Hi!
I discovered that this problem is not afecting on all carriers.
On voodafone Slovenia (EU) is not workin, on other providers MMS are working ok.
...so we have to wait for fix.
solved?
Hey, can you give some more detail on how you solved this for the rest of us?
I'm on a 3G i9020t, I called my service provider (wind mobile) and they told me to "google" how to downgrade back to gingerbread. lol what dicks.
I called samsung device support for the nexus s and they were utterly useless...especially live chat so don't waste your time. They told me to try factory resetting my phone and now all my save data in angry birds is gone. Neoooooo. Oh, and it did nothing.
I hope they patch this soon...i like my MMS and I can't play .avi files now. EFF google! YOUR NEW OPERATING SYSTEM SUCKS! - except the keyboard is much better.
[UPDATE] I tried it while connected to WIFI and it works fine. I can send & receive now. Just wish I could do that on 3G
Vote for a fix here: http://code.google.com/p/android/issues/detail?id=23233&colspec=ID
But it would still be great to know what Kalimdor did to make it work...

No on Simobil Slovenia MMS is not working!
It seems that ICS can use 1 APN for both Internet and MMS. So you can try to combine both into 1, if you currently use 2. For APN type write default,supl,mms and combine proxy address etc. into one.
But if your phone company uses two different apn points (mine uses internet and mms) it will probably not work... Anyone able to help, what can we do?

same for me. MMS works only when I connected to WIFI
Same problem here....internet works but no MMS download/upload
I had this problem on 4.0.3 but it was fixed in 4.0.4.
Ive had the same problem pop up on certain custom ROMs and wasted a lot of time screwing around with APNs, kernels, etc unsuccessfully but finally solved it today by installing goSMSpro -stock and handcent sms didn't work.
Try this first, then try 4.0.4 upgrade or better yet a custom ROM like CM9 where everything works.

[Q] Lost 3G Data on Cricket. Can anyone help?

I currently flashed and activated the Epic 4g (Sph-D700) on the cricket network, and everything was working good. But stupidly I flashed the Cyanogenmod 7 RC3 for the Epic 4g on Sprint network thinking the 3g would work. But ever since then I could never get the 3g working anymore.
Tried many steps; from QPST, APN settings, returning to stock, flashing CM9 Beta 4 on cricket, CM7 for Cricket, trying many ways in many forums to fix 3g, and returning to Cyanognemod 7 RC3 on Sprint and trying to fix it from there.
don't know what to do anymore. I installed an app like root explorer for free and messed with the apn. Tried to mess with the hap secret going to system, etc and reaching ppp. Tried installing the epic 4g different cell phone company fix flash file, the i905 data fix and no luck. I tried using CDMA workshop and QPST and tried a bunch of PRLs and the 3g icon wouldn't even pop up.
The PRL that worked with 3g cricket was 42700 one. Flash cyanogenmod 7 screwed it up. I even used voice dials to open APN and nothing. Even dialed ##8778# and set it back to PDA. Tried dialing #data and mess the settings there. Does anyone have a back up of the apn settings on cricket where the 3g works? I currently have thr $55 plan .
I noticed that on cm7 and cm9 the connection goes to 1x and no 3g connection. Also noticed that I keep losing signal and sounds like its updating PRL.
If anyone can help, please

SCH I535 w/Straight Talk no calling or outgoing texts

I got my ST SIM activated yesterday and LTE connected without having to make any APN changes.
I can receive incoming text messages. Incoming calls go straight to voicemail, and I receive a notification for them but cannot retrieve.
Outgoing calls /messages result in 'no mobile network' error, including dialpad codes.
Have had six different sessions with Straight Talk, whose solution, depending upon the CSR, has been to change the APN, restart phone/pull sim/battery, factory reset, wait for activation, etc.
At one point, Verizon Wireless briefly appeared as the carrier but LTE stopped working.
Any suggestions? I have done all of the above, along with installing several different ROMS, restoring earlier backups, etc.
I have searched and found a lot of posts regarding issues with data, but can't find anything relating to my particular issue.
I am currently on CM13 Nightlies. The phone is not under contract and I have used it with other BYOP carriers with no issues.
Thanks!

I was helping someone else out with that recently. I found that both on CM12 and CM13 it doesn't give you the option to change the APN settings.

I am actually able to change the APN settings by selecting the APN, editing it, and saving it from the menu pull-down. In a few of the ROMS I tried, I needed to put in the updated APN of TRACFONE.VZWENTP. (I laugh every time I type it.. VZ went P heh)
Anyway, in some ROMS it works with the assigned APN and in others I have to put in the updated one for LTE to work. The APN is for internet and MMS, both of which are working at the moment. I need to figure out how to get calls and outbound SMS working.

Yes, I just got the Straight Talk SIM and network code and activated it a few days ago. I looked for the apps but could only find one for account management and auto-APN settings.
I was using a prepaid T-Mobile sim in this phone prior, and had to use an older modem to get data (only got edge since it's GSM on a CDMA phone) working. I am currently installing a newer modem to see if that will help.

Yeah that's the one I saw. I installed it just in case, but it only changes the APN settings, which I have already tried. Thanks though!

LTE is working fine, but no 3g and 2g network!!!!

hello,
I am from India and using Vodafone network. I am facing a very weird problem with my OPO. I am able to receive and use LTE ie I can use internet and send and receive messages.
But the problem starts when I try to make a call. As i dial a no. the phone switches to 3g and I receive a error saying NO NETWORK CONNECTION in about 5-7 seconds. To confirm this problem, I tried to switch to 3g only and 2g only in the network settings. Whenever I select 2g or 3g, my connection is lost and I cant even register to a network
I have tried many other sims including reliance, idea and another vodafone sim with the same result. I have flashed the stock COS file using fastboot to make my phone completely stock including clearing data, internal storage and system. I have tried a lot of roms which never used to give me such a error but the problem persists in all the roms
Please guys help me out
Thank you in advance

I managed to solve the same problem not a long time ago. At the end of this post there are several values you can write in nvram. Try experimenting with the ones.
If it did the trick just don't forget to make a backup of EFS partition
same problem, let me know if you resolve
I think you might need to unlock all bands. Check this out: http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
Notes:*Those modifications need to be redone after radio*flashes.*
I will certainly try that..
But is it possible that the bands I need were unlocked earlier and now they are not, beacause 10 days earlier my 2g and 3g networking on this phone were working perfectly...
On that day I messed up a lot of settings in *#*#4646*#*# menu, could this be the possible reason that some of the bands are now locked???And I also want to tell you that all the options like WCDMA only GSM only etc which were earlier available in the menu are still available
Thanks your replies

Lineage OS 7.1.1: Unable to send SMS messages

Hello all,
I flashed my girlfriend's Sprint S5 with Lineage OS recently without a hitch, all services working perfectly. We ended up traveling, so she went to Sprint to set up a temporary international roaming plan. Everything was completely as expected abroad. When we got back, her phone would not send SMS messages.
We tried the usual airplane mode and such, and to no avail. Assuming something was wrong with the network configuration from travelling, we reset network settings. Didn't work. I then decided to just do a full wipe and re-flash of Lineage OS. Still doesn't work. I then resorted to going back to the stock TouchWiz ROM from Sprint. At that point, under the stock ROM, SMS were sending. Out of curiosity, we flashed back Lineage OS, and SMS will again not send. We noticed that if the SIM card is removed, SMS will send, but the phone would not be able to access 4G LTE. We also confirmed with Sprint that there are no restrictions on the account.
What could be causing this to occur only on custom Roms? Do we need to do a PRL update? If so, how does that work on stock Android?
Thanks in advance!
S5 sprint No outbound sms
I've had this problem for weeks....So far the only solution is using Google voice app....
I'm using LOS 7.1.1 20170207 kltespr nightly, LTE SMS can only receive, sending doesn't work. Only 3G SMS works.
Things I noticed:
Settings -> About Phone -> Status -> IMEI Information. When on 3G, all information is displayed here, when on LTE, only IMEI and IMEI SV is displayed, there's no PRL/MIN/MEID/ICCID anywhere, not even disabled or greyed out, just hidden completely.
ICCID also shows DUMMY_NV_ICC_SERIAL instead of the actual ICCID.
Same experience for me, I've been trying to find a workaround for over a month with no success. Alternative text messaging apps seem to work, but I don't trust 3rd parties with my SMS.
Unable to send SMS
Mike.
Which third party SMS app are you getting to work? Besides Google voice I have had no luck with any third party app?
I'm having the same issue. I'm on Resurrection ROM which is based on Lineage. Since update I can't send SMS at all other than via Google Voice. I can receive SMS and I can send/receive MMS.
I did find that if I change to 3g only for my network settings, I can send SMS. But then of course I don't get LTE data speeds for everything else. So the issue for me at least is tied specifically to LTE. Wondering if there is an APN or other setting I can change that would fix this but so far no luck finding anything.
Bug reported since 01/28
https://jira.lineageos.org/browse/BUGBASH-37
I've run into the same problem or similar. If I set my preferred network type to GLOBAL then I can send and receive SMS/MMS messages but I'm forced to either Roaming LTE or 3G. It's often stuck in 3G after a drive for any distance. If I force it to LTE, then SMS/MMS stops working and I can't place or receive calls either but the network will show up as LTE and Sprint.
To get there from Settings Home -> More (under Wireless and Networks) -> Cellular networks -> Preferred network type -> Choose Global.
Sometimes I can force it back to LTE but roaming if I switch temporarily to LTE then once it connects switch back to Global. Occasionally I have to put it in airplane mode to get the radios to reset and connect but some combo of switching network type and ending up in global and switching into and back from airplane will do the trick.
YMMV of course.
one way I fix it temporarily is to:
cell networks - carrier settings, let it crash
go in again and let it find your carrier
once connected, make a phone call at least to get it ringing
I can then make sms mms.
it's a rediculous work around but it works for me every time
SMS Sending Problem with Lineage 14.1 (31.07.2017)
Heyy
I'm not able to send sms from SIM 1 but can send sms from SIM 2 in Lenovo A6020a46 (2GB) on Lineage 14.1 (31.07.2017).
The same SIM is working good in another roms and Calling + Internet are working properly.
After dialing *#*#4636#*#* in Phone Information - SMSC Refresh then it appeared "Phone no.", 456 and I pressed Update.
But there was no process for saving or updating. Then I reentered in Phone Information but SMSC Shows blank.
What to do??? anybody help in this matter will be immensely appreciated.

I made this file using Odin with the steps from here. I flashed the file, set the connection to LTE aand it worked. https://forum.xda-developers.com/showpost.php?p=71582847&postcount=5908
To fix this issue with having LTE signal and sending SMS at the same time you have to open EnginneringMode app (or *#*#3646663#*#*) and check 'Sms over Sgs support' in Misc Feature Config tab.

If that code doesn't work for you, try to find an app called Engineering Mode MTK. Unfortunately I cannot attach any screenshots yet (I got less than 10 posts).
fix
there is an option in network settings (enhanced 4G LTE mode for comunications etc) i disabled that option and messaging works fine now. before unchecking this option i could only send sms only with phone on 3g mode, now it works fine. i think this option is for hd voice calls via 4g lte.
I see this is an old problem and I´m having the same problem. I can receive SMS, but I can´t send.
But to add to that, I couldn´t connect at all with my previous carrier and changed carrier after which I can use data, call and send SMS. I still can´t receive SMS.
