HELP Troubleshooting. RANDOM Shutoff/Reboot, and wifi not turning on - AT&T Samsung Galaxy Note5

Wifi not working with t-mobile sim? and I got unlock code and unlocked successfully.
WITH sim in, wifi will work, and mobile network works. THEN it reboots after a little while and the wifi stops working. and only mobile network works. When I try to turn on the wifi, it says its turning on, but doesn't.
I've cleared cache, factory reset in phone and recovery mode. Still same thing happens but ONLY when sim gets inserted it. Seems like it'll work for a little bit then the phone realizes somethings off and reboots, makes wifi not work but only mobile network.
I've taken out thes sim for now, and the wifi works beautifully. When I inputted the unlock code, I only inputted the network lock code I was given, there was other codes in the email also, am I suppose to input those as well? Could that be the cause why the software is out of wack?
firmware is on ogg 5.1.1 and for some reason I can't update the firmware, i'm guessing because its not a att sim?

[Q] VPN and APN issue with [ROM/4.1.2] [Dec 19 2012] CM10 | Jelly Bean 4.1.2 - v3.0

This is an outstanding ROM. Only two issues:
1. I can establish a VPN connection, but after disconnecting several minutes must go by before I can reconnect. I'm researching this issue with my VPN vendor, but I'm beginning to think the problem may be in the ROM.
2. Establishing a VPN connection tends to wipe out the APN and therefore all wireless connectivity. The ONLY way to get the APN back is to force the phone to re-read the SIM card. For some reason, trying to change the SIM pin won't work because it tells me my perfectly good SIM pin is incorrect. Strangely, what does work is changing the screen lock method, which then causes the phone to prompt me for the SIM pin. After I enter the SIM pin I get wireless back.
Anyone else having these problems?
Same APN prob when changing SIMs
By the way, when changing SIMs I have encountered the same vanishing APN problem. Specifically, going from a U.S. SIM to a French SIM. On booting, no wireless, no APNs listed, and a search for providers results in an error.
The solution is to force the phone to read the APN list by requiring a SIM unlock -- even though I had to unlock the SIM upon booting. I did this by changing the screen lock method, which then for some reason required me to enter the SIM pin. Trying to change the SIM pin didn't work, because the system wouldn't let me. This suggests to me some bug in the way this ROM boots.
And VPN drops
Hard to say whether this is the ROM or the VPN provider, but I can't get a VPN connection to stay open more than a couple of minutes. Interestingly, I had set VPN to Always On, and when the connection dropped that setting was reset to None.

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.

[Q] HELP!!! My HTC Desire 816 a5_chl on VM is stuck turning off airplane mode

So, recently I was given this device after a friend had followed a few guides on here to try and attempt a sim unlocking for T-Mo. However, they gave up before they could fail too hard. However, once I had recieved the device, I had to order a new sim from VM myself, so that I can use the device. Upon receiving the sim, I noticed that the phone DID NOT AND WOULD NOT detect that a sim had been inserted. I grew worried and decided to run a .exe RUU flash back to stock. When the phone comes back, it doesn't ask for a sim at all. Instead, the setting for Airplane mode is greyed out and says "turning off." I have left the device sitting there for hours, just waiting for it to return to life, but to no avail. What should I do?!?!
Have you tried calling VM and activating the device?
I'm pretty sure the sim is just for LTE connectivity, and that the phone is still CDMA and requires an activation.

That's the very first thing I tried, and to no avail. The main problem lies in the fact that the radios are off. It tried to do self activation multiple times and it panics and fails. Later, I will upload screenies and a video of the issue to clarify the best I can
Try with this secret code that allow you to turn the radio on.
*#*#4636#*#*
Try it with and without turning airplanes off and also before or after..... Hope it helps.

Can't place or receive calls; LTE data and SMS works fine

Hey guys, just unwrapped my new N5x and popped in my sim card. Yet for some reason I can't make or receive any calls!
Calls to me go straight to voicemail, and when making an outgoing call it either immediately says call ended or after a while says network unavailable.
The strange thing is that the entire time I'm connected to LTE (full bars) and data works fine (I can use chrome), and I can even send and receive SMS!
It's been like this straight out of the box. I reset the network settings, then factory reset the device, then upgraded to 6.0.1, rinsed and repeated with no luck.
Probably related: I tried setting the phone from LTE preferred to 3G or 2G but it still says connected to LTE. Even did it manually from the *#*#4636#*#* and nothing changed.
I'm using HOT Mobile in Israel and the American version of the phone. All bands are here are supported.
Any thoughts on how to proceed?
Do US specifc models of phones normally work fine in Israel?
I know I had these symptoms when I managed to accidentally swap my UK model to use USA bands. Only potential difference is that I don't think SMS worked for me.
If someone more knowledgeable knows where the "Network settings reset" pulls values from and to, that might help.
Or which partition holds the data that makes a US phone a US version and an EU phone an EU version (assuming it isn't hardware), we could potentially flash stuff.
Yeah they do. I have a friend with a 5x and his phone is working fine. :/
Check your apn settings, re add them again to test.
Maybe your network do not support lte calls, try it on 3g. This was my solution even thought my network supported volte and worked on s6 but not on my 5x.
I see you tried the 3g option, my problem was another app causing the conflict between lte and 3g. Able to source for another spare sim to try?
I deleted the apn settings - no luck. tried 2 different service providers and same results with both
I havnt installed anything yet and wiped the phone to be sure. Could a stock app be causing the conflict? How can I check?
did you try having your friend put his sim in your phone and yours in his to see if it works?
Yep - he's on the same service provider that I am. Didn't work. Also tried a Sim card from a different service provider.
Here is a solution if you still need it http://forum.xda-developers.com/showpost.php?p=64023143&postcount=10

Phone Stuck Showing "Searching / No Service"

Hello all. I purchased a edge+ today but whenever I insert a sim, the phone stays on searching. I made sure that I rebooted the device and I also tried re-seating the sim many times. I believe the device is unlocked and the imei/esn is in clean standing with T-Mobile. I tried a MetroPCS sim card and it stayed on searching, same thing happened with a Verizon sim. However when I inserted the T-Mobile sim, it sometimes says no service but ever since I rebooted the device, it stays on "searching" no matter which sim is installed. I find this whole ordeal frustrating since the signal bars show up for the MetroPCS and T-Mobile sim but with Verizon nothing happens. Any help would be greatly appreciated.
Yours is G928T? If yes, it does not support Verizon/Sprint even if it's unlocked.
Did you buy it off of Craigslist/Ebay? It might be blacklisted. checkesnfree.com

Yes, it's the G928T but it's not blacklisted I checked. The simcards I was using on the phone were old ones(no longer in service) I thought they would work. I used a scissor to cut my WORKING sim and placed it in the phone and it took the MetroPCS sim. Everything works fine now except calls and text only work with WiFi Calling on. If I turn off WiFi, I can't text or make calls(not on registered network) but if I turn the WiFi back on, it works fine. Any suggestions?
MetroPCS and T-Mobile are on the same network.
Check/add MetroPCS APN.
Setting -> Mobile Networks -> Access Point Names
Add MetroPCS APN if it's not there.

Yeah I know they are which baffles me as to why it isn't working. I tried adding a custom APN but same thing happens. I get calls/sms on WiFi but if I turn it off I get "No Service"
Just go to metro and get a new Sim. You could have damaged it by cutting it. It should be free. ATT gives me then free all the time. Usually, the phone will just auto update the apn settings when a specific carriers Sim is inserted

I went and it turns out the device is blacklisted. This whole time I was rolling with the imei in the phone, after checking last night, I noticed that the imei on the back of the device differs from the one that's actually on the software. I was able to get in touch with the seller and he's coming back to give me my money back. Guess a mod can mark this thread closed.
