[Q] [Fixed] Help! Cannot Send SMS with any ROM!

Hey xda,
My Desire has stopped sending sms's since i installed MIUI-AU 1.6.10 - used many ROMS before but never had this issue.
The first time i switched to MIUI i followed the instruction to flash the corresponding *.DX.zip file before flashing the ROM [see their site] which i did, then flashed the rom - all seemed ok and since then every time i send an sms to any number, from contacts/manually typed or what have you it gives an error - 'message not sent'
Since then, ive switched to the updated MIUI-AU,MIUI 1.6.17 (running currently), RCMix..whatver is their latest build - and im sure the issue will come back with any other rom.
Now obviously following all instructions and all i must have skipped something that is causing this..
Before flashing miui 1.6.17 i wiped everything and my SD card is setup for A2sd with the right partitions and extentions
Im running a CM7 HBoot if that matters.
If anyone has a clue please let me know here - im happy to provide any more information...cheers
Fixed: Guys if you ever get into the Messaging settings>Advanced>SMS Message Centre..don't change the default number stored there - i just called up my provider (Telstra) and they gave me the correct number to use and now everything is back to normal

Did you try to get the settings from your provider? You could try to reset them if you have got an account for the internet portal of your provider. You could also try to call them.
I don't know if you need special settings for every provider, but you can try this.

Thanks for the reply - phones here in AUS will normally get the settings as soon as you insert the SIM card but because i had deliberately messed with the sms message centre number i had to ring them to get that...your post got me thinking what i had changed and it just made sense

Cannot SEND SMS Tried Everything Please HELP :(

All of a sudden today I cannot send SMS.
I was on a really old build of Cyanogenmod12 (April 22nd I believe) as any time I tried to update to newer Nightly builds I lost all Sprint service could not make/receive calls or texts, etc.
I decided I was pretty fed up with CM12 so I decided to go ahead and migrate to AICP. I wiped everything TWICE in recovery, loaded up AICP and it works fine, I get LTE signal, etc. However I cannot SEND SMS, I can RECEIVE SMS I just cannot SEND. I had done some data restores with Titanium and I figured that somehow some way that might be messing with things. So I did another 100% fresh install after wiping everything.... I can send/receive calls, receive SMS but I cannot SEND SMS
I am really at a loss here guys, ANY help would be greatly appreciated

*#*#4636*#*# change it to CDMA wait 30 seconds send an SMS and do *#*#4636*#*# again change it back to late/CDMA n should be ok
Sent from my SM-N910P using XDA Premium HD app

I stayed up all night last night working on this, let me update the thread with what I have done so far.
I was looking at some stockish ROMs and I noticed that there were warnings on some of them stating that you needed to have the Sprint OTA 5.0 update installed prior to flashing, which I actually never got. My phone came out of the box with Kit Kat and I never installed the 5.0 update, I went straight to CM12 5.0 instead. So I had a theory that there might possibly have been some sort of network data profile, etc or something out of that official 5.0 OTA that I never got that was somehow causing me problems. I decided to revert back to complete bone stock.
I wiped everything and flashed the N910PVPU1BOB7 file (MD5 = 7304e42cf0e241553d8db9e3c3eeed81) which was the official Sprint 5.0 OTA. Loaded it up, updated the PRL, Network Data Profile, etc, etc, etc.... everything works (relatively speaking...... TouchWiz sux balls of course). I have LTE signal, I can send/receive calls, I can send/receive SMS... all good.
So at this point I decided to re-wipe and flash AICP, with the emotion Kernel (latest builds on all). Load it up.... same problem as before. I have LTE signal (stronger than on the stock Sprint ROM), I can send/receive calls, I can receive SMS but I still CANNOT SEND SMS
I tried a few things at this point. I tried to manually reset the Sprint network connection on the phone by dialing ##72786#, this did not work, it returned an error "incorrect MIM code". I tried the *#*#4636*#*# that I have seen suggested in multiple places, this also did nothing, it returned an error "incorrect MIM code". I also noticed on the "mobile networks" tab, and this is true for BOTH CM12 and AICP, that it has the setting at "Global" by default and everything works with exception of sending SMS. Now when I click that tab it only has 3 options LTE, 3g, 2g.... for some reason "global" is not an option, neither is CDMA. Whenever I select LTE it automatically drops me from the Sprint network PERMANENTLY until the ROM is re-flashed there is no way to reverse this. I cannot even dial the manual programming codes "*#* etc" as it just simply says "no network service". If I try to automatically connect to the sprint network through the network operators tab it does in fact find Sprint as my provider, however if I click on Sprint to connect it processes for about 2-3 minutes and then simply returns an error of "cannot connect to the network at this time, please try again later". Again the only way to reverse this is to re-wipe and re-flash again which puts it into the unselectable "global" network setting by default where then I will have LTE signal, I can send/receive calls, and can receive SMS but not send SMS.
So that is where I am at, I stayed up all night last night wiping, flashing, and testing different things over and over. Nothing seems to work 100%, except the stock 5.0.1 OTA which is what I am on now. I really hate TouchWiz and for some reason I get a much weaker LTE signal on stock compared to either CM12 or AICP (I have no clue why this is). I am really at a loss here why everything works on the custom ROMs except for sending SMS..... willing to try almost anything to go back to a custom ROM.
Let me know if you guys have any other ideas.

Well great news I have finally resolved the SMS send issue

*#*#4636*#*#

pbedard had tried to help me with the above post (which I appreciate, thank you), and I have seen the same advice in other threads. One slight problem though, he slightly mistyped the manual programming code it is actually *#*#4636#*#* not *#*#4636*#*# which I had tried entering ohhhhh I dont know 30 times? :silly: And it always returned an "invalid MMI code".
I had tried everything and after spending a full day on TouchWiz I was determined to fix the issue so I could go back to a custom ROM. I was even manually creating and deleting APNs, etc. Nothing would work. Right as I was about to finally give up (after literally 12hrs of researching the issue and testing fixes) I was reading the official CM 12 thread and came across the "fixes" post:
http://forum.xda-developers.com/showpost.php?p=57613217&postcount=3
Because I had tried entering the manual programming code so many times I happened to notice that the last 4 key strokes were not what I had been entering. I entered the correct programming code, boom the Phone Info menu pops right up I follow the directions and what do you know send SMS finally works .... wow what a relief, I am on the latest AICP release on the emotion Kernel and everything works like a charm.
Also by setting the phone to LTE/CDMA through the manual programming menu I have the strongest LTE signal by far, full 100% bars at all times (I live right next to a Sprint tower). I have never understood why I only got 1-2 bars on the stock ROM and 3-4bars on CM12/AICP through the default settings. Anyway thanks for help and I will list out exactly what I did to get it working.
- 100% Stock ROM
- CF Auto Root and TWRP install through Odin
- Reboot to recovery
- Wipe Dalvik cache, system , data, and cache
- Reboot to recovery
- Flash emotion kernel (optional)
- Flash latest AICP build (or custom ROM of your choice)
- Flash latest stock Gapps
- Reboot system
- Confirm Google Messenger is the default SMS app (it will already be if you flashed 5.1 stock Gapps)
- Dial *#*#4636#*#* ("Testing" menu screen will pop up, select "Phone Information")
- Scroll down to "Set preferred network type" click it and scroll up and set it to "CDMA auto (PRL)"
- Wait until 3G signal comes online (takes about 10 seconds)
- Change "preferred network type" to " LTE/CDMA auto (PRL)"
- It should take another 10 seconds for LTE signal to come online and you should be good to go to send and receive SMS ! :good:

[Q] MMS not working for CM 12.1

Anyone else having problems sending or receiving with MMS on the nightly builds for CM 12.1? My SMS works just fine.
I have Ting, which may be part of my problem. I am using the same APN settings that use to work for MMS in CyanogenMod 11.

Yep. I've been fighting this for 3 days now. I must have tried every CM 12.1 variant out there with the same result. The APN list shows Ting... but you cannot select it, modify it, or save it. Reset to Default APN doesn't work... Rebooting 18 times doesn't work... flashing the various APN "fixes" like for FreedomPop, MVNO_CDMA, etc doesn't work. But like you... SMS, Phone, and Data (on WiFi) work fine. However, MMS and data (on 3G/4G) don't work.
What has worked... backing off to either a Stock ROM or CM 11. So something in these recent CM 12.1 builds is just broken. The only reason I was trying to upgrade from CM 11 to CM 12.1 was because of that StageFright vulnerability. So I may just go with the Stock ROM until I see the CM 12.1 APN issue for Ting has been resolved.

I've been using the clear google messaging app from the TBO updater app and just installed their latest hangouts to try. They both have been handling mms better than any other messaging apps and sometimes the stock mms will work by just having the gmessenger app installed. I've been rom hopping lately and it seems pretty much the same for me across most CM12.1 based ROMs. Also, you could try editing the actual apns-conf.xml file under /system/etc/ back it up first tho and for permissions 644. from my Virgin Mobile Tri-Band model S3

You should be able to modify Ting by touching the name, even when the button for selecting it is absent. You may need to add "default" to the type once you have it open. I have Ting and I have had to deal with this somewhat as well. I believe I saw some recent Ting APN updates get pushed through as well. Have you tried Exodus?
There is also another thread in here about lollipop and 5.1 which has information that may help.

Exodus? Nope... but I'll be checking it out now!
If you don't mind me asking more about the APN. How many are actually needed in there? If I were to delete all the APNs and just manually setup the 1 needed... is it just the LTE version pointing to http://mms.plspictures.com ... or ... http://mms.sprintpcs.com and making sure the "type" has "default" in it? It's the one thing that I can't understand. Out of every forum I've read... not 1 mentions just blowing all the APNs away and just simply adding a single APN for Ting. I don't think I really need all 8-16 APNs (depending on the ROM you flash).
And this question is open to anyone. Is there any reason you have to have all those APNs for other networks like Boost, FreedomPop, Boost Mobile, etc? What should the APN contents be for just Ting? Inquiring minds want to know.

I actually tried that myself but didn't have any luck with it sticking past reboot or even holding the data signal right. It's possible it might work. I don't know enough about APN's to say for sure. Did you try adding "default" to the beginning of the Ting APN type and then save it?

APN won't stick

I have unlocked s6 and APN won't stick. When put into network mode automatic I get to input APN and it works until I let phone turn off screen or I manually hit power button. When I get back into phone the APN setting I input, for t-mobile, are gone. There are Sprint APN listed but I can't choose nor add or delete any. If I choose LTE GSM auto prl through one of the service menu's I am able to again choose APN and input what I want but at sleep and rewake the phone goes back to not listing the APN and having greyed out sprint APN. Phone works but have data issues here and there and sometimes have to reboot to get lte to stick. Lock screen sometimes shows T-mobile as carrier but usually shows Sprint. I can still make calls and use LTE data on my t-mobile sim when it says Sprint as carrier but I think my data and mms issues would be fixed if I could get the dang APN to stick. Any ideas? Different rom? I'm on 5.1.1 OJ7

This is a really old thread, but since I've been struggling with this issue for several months, I think this is the place for a reply.
There are several problems with a "sprint" unlocked S6, but the most annoying (other than hands free activation) is the APN settings going back to default and being "locked" until you reboot the phone. When in this "locked" state - you will not be able to receive MMS messages.
I have found that deleting (or simply renaming) the customer.xml (/system/csc/customer.xml) stops the resetting of the APN - and interestingly opens up the additional configurations under Mobile Networks -> Network Mode to choose GSM/WCDMA/LTE.
After fixing this and fixing hands free activation (https://forum.xda-developers.com/sprint-galaxy-s6/help/hands-free-activation-t3199214) the phone now performs VERY well on T-Mobile, just like it belongs there

I just checked my device on 7.0 Nougat and I can't find that file (there is no folder in root>system called "csc"). Any idea how I can fix this?

You may not be allowed to view certain system files for some reason. I believe you have to be rooted to delete them. You could also try the system update first if you are stock. But probably best bet either way would be to start with clean install of whatever ROM you use or the stock ROM from TWRP. I've been able to delete the files from skyhigh and Rick Wardenberg's ROM.

Edit: I recommend es root explorer to do the dirty work.

if it's not too late
First you need your msl code I can help if not.then use data daily code or an app idonee don't get a fake I found on code after you do that you just need to change mms and apn setting see screenshot.i have 920p on 7.0 stock rooted running on t-mobile lte get mms everything

I cant make or recieve phone calls but everything else works even my wifi number work

3 days ago after getting new apn setting for metropcs, when i rebooted my phone it stopped making and receiving calls

APN settings affect data access, not calls.
Is the imei properly displayed from the dialler? Was the ROM changed or altered?

yes the imei is properly displayed from the dialer. im not sure if rom changed or altered. how do i check

The simplest solution would be to flash back to a stock rom using Odin; however, flashing the stock rom may require you to perform a factory wipe before booting the stock rom for the first time.
