Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?

Hoping someone can help me figure this out.Created a new topic because it seems a bit different from the other "no sim" topic.
I have an i337 on MF3 that was rooted and unlocked using jortex's method and chainfire's region unlock.

I used it on Tmobile's network for about 16hrs without problem, then it suddenly started showing emergency calls only and asking to insert sim. I've place the tmobile sim in another phone and it worked fine, also put an unactivated AT&T sim in the S4 and it sees it. The phone is still booting up with the samsung custom screen. Any ideas on how to fix?
Thanks in advance.
I used Odin to flash a NC2 firmware. I found the firmware in the thread will the leaked KK files. After flashing that firmware ive been unable to connect to Net 10 service with either a ATT or Tmobile SIM card. If i put the Verizon SIM in, i almost immediately see 3G is available. I flashed a second (updated) firmware, and i still have this issue.
Is this a known issue? Anyone else have this issue? Im using BigginsROM cause flashing Hyperdrive causes a black screen when booting. I presume its cause HyperDrive isnt on NC2/NC4 yet. I hope this isnt permanent cause itd defeat the entire purpose of spending $900+ on the phone and accesories.
Any info/help would be greatly appreciated. If ive merely derped something feel free to let me know.

I installed a SIM card info app. The app says that the phone is network locked to Verizon. The phone number that is showed is associated with the Net 10 AT&T SIM. Still says network locked and SIM operator is Verizon.
While further researching the issue i found that the servce menu reports "Network: UNBLOCK." The conclusion is that that means the phone is SIM locked. How in the world would i have managed to lock my phone?
While even further researching the issue i found that it might be the NC4 ROM that i flashed when i was having problems getting the KK leak to boot.
Edit.
I hope there is not a super obvious solution I missed somewhere, I apologize if I am hasty in posting this question, but I cannot understand why my AT&T l337 is not working with my Canadian mobile carrier, Wind Mobile. I do not get the network lock screen with the pin/dismiss options, and the phone picks up on signal, but it gets no data and still prompts "emergency calls only" when I try to make a call.
Phone is rooted stock 4.2.2 NC1, safestrapped, with an MF3 modem. I got the phone new when it was already on NB1 in May 2014, so the service menu unlock method was obviously not an option. I followed the steps in method 3 (@NewToGalaxy) from the @bvzxa3 "possible method to sim unlock" guide, http://forum.xda-developers.com/showthread.php?t=2595457, it does not seem to do anything but remove the initial "pin/dismiss" network lock.
I tried enabling AWS using the "enable AWS on AT&T samsung S IV" @zaryan guide (http://forum.xda-developers.com/showthread.php?t=2291589), but when I try to enter the *#7284# into the dialer for step 3, I get the same "Connection problem or invalid MMI code" I get when trying to use some of the options in the *#0011# service menu.
I have searched around XDA, but I did not find anyone who was experiencing the same issues I had. What am I doing wrong? Flash the MF3 modem, run regionunlock, insert non-AT&T sim (and all the combinations of steps therein). How can I enable AWS if my phone can't access those service menus?
Based on the information cloud-x provided in his sim-unlock thread http://forum.xda-developers.com/galaxy-s4-att/help/i337-sim-network-unlock-assistance-t2808211, it seems like receiving an unlock code from AT&T is not an option since I'm only three months into a contract, and normal unlock code vendors may not be able to pull codes. At any rate, I am in Canada for a limited time and I hope to solve this issue before I return to the states and cannot test my Canadian sim.
I'm sorry I'm kind of a noob and if this situation or issue has been dealt with before, I just hope someone can point me in the right direction.
http://forum.xda-developers.com/showthread.php?t=2285431 follow the state at the beginning of this thread after rooting and installing shortcut master lite use the secret code explorer and scroll down to code 27663368378 there you will see all the options needed. I was on NC1 when I did this
I337 stock NC1, rooted, unlocked

Ok, I'm going to try to make a long story short, i hope that i've posted in the correct forum, I've been scouring this forum and others but nothing I've found has quite fixed my issue.
Got my S4 locked to Bell in Canada. Heard it was really easy to unlock [service menu *#0011# method] but once I got to Indonesia [for travel] expecting to be able to use my phone I found that the service menu was no longer available. Ok, no problem, there must be other ways;
I ended up paying for an unlock code from a site, it didn't work. In fact, immediately after I press 'unlock' it would say 'network unlock unsuccessful'.
I thought they gave me a faulty code but when the code I bought FROM Bell was the exact same one, and had the exact same problem I figured it was likely 'region locked'
I ended up flashing a stock rom with odin, one from a weird unlocking site, and eventually I got it working. The only problem was that whenever I'd go into screen lock I'd lose reception and have to airplane mode on and off to get it again.
After Indonesia I went to Turkey, was unable to connect at all with one of their service providers, but had no problems with Vodafone. I think this may have been a side effect of regionlock away app, I needed to use that as well.
Once I got back to Canada I went custom recovery with cwm and flashed Cyanogenmod. This was fine, no reception problems, 10.2 - 11 was all good.
NOW I am in Poland, and getting the same problem I had in the first place. Whatever Cyanogenmod did, re-locked my device, in some way, I'm guessing.
I'm now rooted, with TWP recovery, running Android 4.4.4 Dave GPE rom, and would REALLY like to be able to use my Polish sim card with this fantastic setup. Chainfire's regionlock away app does not work, gives me a CSC error message. My phone now says it's an i9505 instead of i337m
Anything I have overlooked? Any way I can get this fully unlocked and working the way I want it to?
*NOTE* I can't access *#0011# service menu, even though I flashed [i think] stock dialer.
You are not in the correct section
You need to be in this section.

I can help you a little though. If the unlocking methodes fail, then it's usually because you don't have an older modem. You need to look for the modem you should flash in order for it to work. Afterwards you can flash the modem again you are on now. If you can't find it, just flash an old modem and try.
I find it hard to believe that Cyanogenmod could have caused this though.
Cool, that will be my next phase of attack. I appreciate the redirect and thoughts (Y)
I have a galaxy S5 on AT&T that I'm trying to use a straight talk sim in. (Att towers) whenever a sim is inserted into the phone I get "Sim not allowed mm#3". I used a reputable service (cell unlocker) to unlock the device. The IMEI comes up clean as well. I've also changed the APN settings, but it won't connect. I'm trying to port from a galaxy s3.
I would also like to quickly add that the t mobile straight talk sim works just fine, but using that is not an option as the service is atrocious.
Another thing, the ATT sim works in a galaxy S4 with no issues. They are both sims for straight talk. Any help is really appreciated, this is baffling me.
Just went into the service menu with *#0011# and in the debug menu i can't actually see a MM reject cause. CARD_ERROR: Unknown and PERSO_FEATURE: UNSUPPORTED are the only relevent info i see here. The phone has been unlocked, is there a way to flash the service menu with ODIN and reset it all to stock? I know this won't lose the unlock, so in the off chance that I did accidentally click on something in there before will the tar.md5 file fix this? I read a post where user sanquante said he had to flash the PDA.MD5 file and it fixed it...I'm assuming he meant the tar.md5? Thanks for ANYONE willing to help. I really could use it.
bump...
