[Q] L720 Unlocked with T-mobile rom, but text sometimes take long - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

So I unlocked my S4 L720 by Using this ==== > " http://forum.xda-developers.com/showthread.php?t=2703955 " I am using it for T-mobile. Once it was unlocked i flashed back to NAE I have signal I have 4G/H+, but kept having issues with different roms. On every rom I have used either from sprint s4 or tmobile s4, 2 out of every 10 text that I send say fail, then I click resend and it says sending. Also I sometimes wouldn't be able to make a phone call, as if their wasnt service, but i could clearly see full bars and H+ signal. Finally after about a minute or so it'll send. With every sprint rom I had the S4 didn't receive mms, but I could send them. Then with some tmobile roms when i would make a call it wouldn't be able to hang up, but I would be able to send/receive mms. I re-did the whole unlock process 3 times and still the samething. Anyone else had this problem? I have honestly tried about 10 different roms from sprint/tmobile. Im currently about to try a stock tmobile base rom DEODEX see if that'll help. Im not exactly a noob, but im also not smart developer. Any help would be appreciated thanks everyone!

Sounds like an APN issue. What APN settings have you been using?

[Q] Samsung galaxy s4 sgh-1337 will not receive mms or group texts

I am in need of some serious help, I purchased an s4 on craigslist from an AT&T customer. I verified the phone at the store, and it was an active AT&T phone when I bought it. I then transferred my phone number to a new Straight Talk Sim, and put the sim in the galaxy . I set the APN settings to the support reps recommendation, and everything worked besides receiving group texts and receiving mms. I thought it was the APN settings, so I tried every setting I could find recommended on this, and other forums. None of them worked. The solutions I was able to find included rooting my phone, which I don't have time to do. Since I was unable to use the phone how I needed without mms, I gave up with straight talk and ported my number to a AT&T LTE gophone account. I figured that straight talk was the problem, so I was excited to transfer. Well, after porting today, I have faster Internet, but mms and group texts(incoming of both) don't work. I can send mms, but cannot receive it, and I can send group texts, but not receive them. I am using the default att settings that came which the phone as instructed by the rep. In the AT&T store today. If anyone can please assist me in figuring out why this is happening, and what can fix it, I would be greatly appreciative. I did a search for the APN issue before posting this, but what I found was related to getting it to work with straight talk. I just want it to work with ATT now. Thank you in advance for any help..
Is your mobile data turned on while you try to download it? It may seem silly but I didn't realize it had to be on before ;P
Data is on
Data is on, and the outgoing mms and group texting works. On two carriers now, the incoming mms and group texting does not work. Really need a solution for this if anyone can help.

go to settings>options>mobile network and make sure that "data services" is turned on then send an mms to yourself and see if that activates it.
Data is on. Something with the phone is going on.....
To my understanding, this has got to be a phone issue. The data has been turned on . The outgoing mms is working. The outgoing group text is working. I have been on two different sims with different carriers, and still have the same issue......

I'm having similar troubles:
I CAN send mms,
but I can NOT receive images [although I did when I first set up the phone a few weeks ago, it was automatic image retrieval]
NOW when receiving a mms, a white download button (within a yellow box that gives me the message size + expire info) does not work. I tap "download", and it shows it's trying, but then I keep getting error messages that the download failed.
For purpose of testing the DATA feature of my service & phone I turn off the Wi-Fi.
I'm able to access the internet via data.
I'm able to make calls
I'm able to send texts
I'm able to send mms
However, my phone can NOT retrieve mms sent to me
I've tested repeatedly sending mms to myself. I can send - NOT receive.
Error message: "Message not downloaded - Review message and try again"
I try again, and then the next error message is: "Message download failed"
I don't understand that it worked before seamlessly for a week (after changing APN settings 1x after initial set up of service) and now I can only send, but not receive!?!
I have a factory unlocked AT&T Samsung S4
Using NET10 service with Net10's AT&T Sim Card.
I actually just got off the phone with Net10's Tech Support. Was on the phone over an hour with Service Tech Rep. He was very kind and patient. I had the correct APN settings. We changed some to test = to no avail. Upon my request he gave me different APN settings to try, beyond those that should work for this phone, in case it would work. He stayed with me on the phone while I performed a "Backup & Reset" and then gave me the settings that should apply to my phone. Still the same problems. He concludes that the issue is with my phone.
We do have a local AT&T store. Is there any reset or other options I could request they please do for me????
Thank you in advance for any ideas, guidance that may help!!
PS: My current APN settings from Net10:
Apn name-NET10
Apn- tfdata
MMSC-http : / / mms-tf dot net
Mms proxy-mms3.tracfone dot com
Mms port-80
Fix?
Did you ever figure this out? I have searched high and low and have exactly the same problem, everything works except RECEIVING MMS. I'm on Straight Talk. Please, please, please help!
Why not just Odin the phone to 100% stock. Solution done.

MMS?
Not sure what that means, but if it will work, please explain. I can root. :good:
did you had an iphone before? make sure to turn/sign off imessage in your previous idevice. IT happened to me as well. ITs one of the damn apply/imessage glitch because when you activated imessage it added your number to their cloud server.
Are you back on straight talk or on att? What messaging app are you using?

Not really the phones are almost identical as far as software and specs. I ran numerous ATT Roms without a problem. You do have to be sure that the version of the ROM you download is the non safestrap ones. I recommend Golden eye. Its pretty much stock touchwiz with the necessary tweaks.

[Q] LG G2 Noob here.

hello everyone. i just recently purchased a vzw LG G2 and was wanting to use it with cricket. I know there are many threads and posts about this but after 2 weeks of searching and literally trying everything i figured it was time to throw in the towel and post my situation. So as stated above i bought a LG G2 VS980 about 2 weeks ago and i currently have cricket service unlimted text/talk 20GB data. ok so ill list my issues and what i have tried to correct them
1. From the start i put my sim card in do the whole activiation thing over wifi and when my phone comes on it displays and H which i know is 3G service. I live in chula vista CA. my husbands phone recieves 4G LTE so i know we are in a good area. Now this is where it gets weird, when im connected to wifi the H turns to 3G and even 4G LTE will pop up randomly. My data works fine just slow of course and i cansend texts and calls but no MMS unless i use a 3rd party text app like Chomp or Textra.
2. The infamous sim card icon with a "?" . Are there any solutions to fix this? i have called LG tech support, cricket tech, took it into a cricket store, called VZW almost everything besides taking to a cell phone shop.
OK so i have tried every APN there is out there i have tried the ATT,AIO wireless, cricket,vzw, literally all of them and no diffrence besides recieving a MMS rarely. And yes i restarted my device after every APN input. My phone is currently set on global, when i try to switch to CDMA/LTE after 20-30 seconds it comes up with no network and says i must go back to global. i switch it to GSM and i have the GSM only or UMT only (maybe)? or GSM/UTMS. Not sure which one i put exactly but i put the GSM/UMTS mode and comes up the RAT networks here im confused and really didnt mess with it to much. but it will sometimes say E.
I am also wondering can i system update? i attempt to but it says failed. i kinda know that you cant update a device on any service besides its original one.
Now what are the harms of rooting and flashing? does my phone lose value? like i said im a NOOB here and this phone is literally brand new. I appreciate ANY help i get. If you have any questions PLEASE contact me asap. There is probably some info i forgot the add but i will be waiting for any kind folks to help me out

Unlocked Verizon Samsung Galaxy S5 for T-Mobile. MMS problems again..

Alright, so just recently something has changed with my phone where I can't send MMS anymore. I receive them just fine. Also, group messaging sometimes get received and sometimes don't.
I've tried everything from changing all the different types of APN settings I know to changing the preferred network mode.
The phone is not rooted.
This problem has racked my brain for days. Any suggestions will do.
Thank you

(Verizon VS995) can't get 4G data and Text/Calling to work in the same network mode.

I've tried searching on this and couldn't really find any answers. So I have a rooted VS995 (Verizon) and I have to change my network mode in order to get 4G data, but can not receive calls or texts.
[Settings > Mobile networks > System Select > Network Mode]
Here are the results I get.
Global - I get 3G data and I can call and text
LTE/CDMA - I get 3G data and I can call and text
LTE/GSM/UMTS - I get 4G LTE data, but can NOT send or receive calls and texts. Incoming calls go straight to voicemail, calls out fail with a no network detected and texts just say failed to send.
I should add that this all started a few weeks ago when I was flashing a few different roms one day to see which one I liked. My phone worked normally before I flashed a rom (can't remember which one) and now it doesn't matter which rom I flash, I still get this issue. I've been dealing with this for weeks and it's gotten really annoying.
I am DirtySanta Rooted, I have tried installing several different kernels and several different roms with no success. Is there something I am missing? Is there a Radio file or something that I need to flash?
I am even contemplating unrooting, going back to stock and then attempting to re-root, but I fear that I might have to flash a newer OEM that will disable the root method.
Any help would be greatly appreciated.
EDIT: It's late, I'm frustrated and I just realized that this thread is probably supposed to be in Questions and Answers section. If a moderator could move it, that would be great.

Sorry for the late response, I was away this weekend.
I ended up flashing just about every rom and kernel I could find and now somehow it seems that it is now working as intended.
Lucky. I still have the same problem, been flashing since I got this phone and not a single one can I get it to stick with service after boot.
