Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.
Maybe the IMEI is banned for some reason?
Never heard of this issue until now
Have you tried to flash a firmware that aren't from any carrier?

Yes I did, flashed the USA unbranded kitkat rom.
Just got the chance to test with two sim cards from different carriers:
Carrier #1: Registered on network, no data traffic, voice call drops just after trying to call, signal ok
Carrier #2: Registered on network, data traffic seems ok but can't navigate, shows H+ and proper APN and traffic arrows activity but when you try a call it says "Mobile Network Not Available"
Can't send SMS, they stick with a "Sending" status and wont get past it.
This phone was purchased unlocked without a contract, can't see how the IMEI could be banned, plus we do not have regularization for IMEI ban in my country, it's currently a mess.
On a side note it does not detect the sim's phone number which it does on any other phone.
Maybe it's some hardware related issue?

Well that's interesting
My phone can't detect my Sim's phone number either (though i don't know If it is only for me)
Have you tried to flash a ROM? (from XDA)

The sim number information depends on the sim itself, most carriers register this information within the simcard so when you go to status you may retrieve your own phone number but I have seen sim cards without this info. The sim cards I tested do have this information and were available on a Galaxy S5 and Xperia Z1 but this E1 fails to read this information which kinda indicates a problem. I don't remember the codes for debugging the sim and network info or I'd give that a shoot.
I will try a custom rom, maybe a different kernel and see if the behavior changes any bit.
I am bidding on a Z1 Compact for this friend, should be a proper replacement and a hell of an upgrade, just concerned about E1's loudness which is certainly superior.
Interesting, I also get this if I don't reboot my phone after like 5 days.

I took my girlfriends S1 on holiday with my 3 network sim in it, when we came home I put her T-mobile sim back in, now it will not connect to the T-Mob network, it will connect to 3G? Putting the sim in my SNote and all is well. I have since install a custom rom to see if that would help but still no good.

Believe me I have taken the sim out and tried it in the "wrong way" lots of times. I have also looked at your solutions page before, very helpfull. But why will the sim work on one network but not on another, and the non working sim will work in another phone????

Check the modem on both phones.
If the phone that doesn't recognize T-mobile has a different modem, then load the modem that the phone that works has through oden or CWR.
Hope you know how to check the modem and load new ones.
Good luck

This will happen as T.Mobile may be using a different Radio band ..most likely you changed the APN and Network settings when you used it with another SIM Card , whilst abroad ...all you may had to do was check your Network Settings in menu> settings>wireless and Networks> Mobile Networks and reset it back for the T.Mobile network, initially
To understand this better read this http://en.wikipedia.org/wiki/UMTS_frequency_bands
at the same time since you upgraded by flashing to JB, you may have to select a new modem that is suitable for JB, you will find all modems at My Android Collections
Data but no calls
Me back again, I have tried all xx modems, reverted back to stock rom, then GB, them back to CM10. When I first turn on phone it finds network (i'm on a giffgaff sim now) it says GiffGaff at the bottom of the screen for about 2 seconds, then it says emergengy calls only. I can still connect to internet. APN settings correct, IMEI correct, In Settings - About Phone - Status, i'm connected to network, service status = out of service, mobile network state = connected, my phone number = unkown. Where can I go from here?
More
Another thing I have just noticed, when I take the sim OUTwhen the phone is still ON, the "no network" on the screen turns to giffgaff,

Try to set your phone number by following this guide , it was written for a Korean version, so just adjust it for your phone version.

Thanks for that, I have now got the number under Status, but still says out of service.
Nexus 6 UK user on EE network. Started to have this problem about 2 mouths ago no signal emergency calls only, reboot the phone still no signal remove sim and put it back in works. This is happening about twice a day. Was running latest stock with root so changed to chroma custom rom thinking it could be radio problem but still happening. Got a replacment sim thinking it was damaged still happening. Phone is over a year old so starting to think hardware problem. Any help would be great.
Cheers
Have you checked your IMEI number?

Hi bushako the IMEI sames okay, I have flashed stock MMB29Q on today with no root to see if it makes any different.
sounds like neither a hardware nor software issue, but a carrier issue.

When you remove and replace the sim card, is the phone on or off? Reason I'm asking is because I'm thinking about a possible problem with the contact pins of the sim card *slot*.
Also wouldn't hurt to check on the sim status next time it stops working.
System settings --> about phone --> (check that baseband version is showing something reasonable, then Status --> SIM Status and check what is under signal strength, cellular network type, service state, cellular network state, and IMEI.
Another thing that you may want to look at, is at System Settings --> wireless&networks/more --> cellular networks --> Preferred network type, and also in Network operators, make sure that you hit the button "choose automatically".
Now, the reason I want you to set it to choose automatically, is because of a glitch I've seen a few times on my service provider here in Canada. If it is set hard to my service provider, occasionally, it will be unable to connect to the network. This is especially the case when I'm *entering* a service area from somewhere that has no service. Note that my service provider uses only ONE MCCMNC, so go figure. Just make sure that you select choose automatically.
You can also try resetting the radio by putting it into airplane mode, counting to 10, and then back to normal.
Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?
Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.
It happened again. And i am missing calls like this. I will smash it with a hammer
Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.
Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?
Should i have at the mobile networks auto detect or manual and my carrier?
Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!
Teddy
No one experienced same issue before?
So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now. All my bars went to 0 with an x on it and I couldn't do anything on the phone. I went to an ATT store, got them to give me a new activated sim and I put it in my phone and all my bars came back.
My phone says VoLTE again too by the signal bar area. I also tested a text and it went through fine. I received a phone call and while it works fine, it sounds like junk now. Like it is no longer actually using VoLTE like it always has. My phone doesnt seem to have any data however, when it should have LTE just fine. I also cannot make any calls, even though it says VoLTE on the phone, it just re-routes to ATT customer service instead of going through with the call.
When I go into the network area in settings it says no IP address either. I looked and my APN is set to nxtgenphone, Preferred Network Type selected on LTE. Before ATT deactivated my sim card LTE has always worked fine, and LTE should still work fine. It is only the 3G network being shut down. Also given the fact I have the VoLTE icon the phone is apparently connecting somewhat to an LTE network.
So does anyone know how to fix settings to get data working again? Is it just an APN that needs to change? What is everyone else doing with the network shutdown and has anyone else had issues like this?
I had the exact same issue, your issue is in fact APN settings I'm having them as well. Try deleting your current APN and putting in a new one. Once I got a new sim my APN reset I could call but no data and no text. I have half of the APN information in place and have data and basic text, but once I input the MMS port the APN data disappears still trying to figure that out. Not sure if anything I typed is helpful but at least you know your not alone with a mi11 on ATT and it can work

Thanks for the reply. I tried deleting the MMS port and also the proxy just now and data didnt come back. I will try searching around for more APN info for how phones are supposed to connect now and see if I can find anything.
It looks like from what I could find that it is due to an IMEI whitelist ATT has, blocking data connection on any device not in their whitelist. The solution seems to be to root the phone and change your IMEI to a whitelisted model.
While my phone is rooted my IMEI is not cloned I definitely would not share my IMEI with ATT. When I got my sim card yesterday I had the attendant activate but I did not provide my phone so he did not get the IMEI from my phone. If you got a sim and they input your IMEI that could be a problem possibly. Just a suggestion to try and get a sim activated at a store without your phone.
I had also heard that most ATT MVNOs were not having the device whitelist forced on them yet, so I went and tried 2 different ones yesterday. Both failed to get the phone working on their network with their sims.
Before I went through the hassle of rooting (and most likely losing payments) I tried ATT again anyway. I used their online customer service chat and the first person I chatted with said he could help me with the lte data problem and the IMEI issue. I was skeptical, but he actually did fix it all up. He just needed my sim ICCID and my phones IMEI1 and he submitted the info to their backend people for adding to their system. It took almost an hour and a half for it to get added, but overall it was a pretty painless process and I was browing the web most of the time while waiting in chat. I now have LTE data again, VoLTE again, and "5G" too (which ATT 5G is really just one or two more features than normal LTE and is no faster in speed and uses LTE data bands). I attached a screenshot showing the data and VoLTE working on my phone. The first signal is ATT, the second is TMobile (which has always worked and never had an issue, their 3G network shutdown is going on for another 4-5 months)

Happy you are back up and running and I'm glad that you found someone at ATT to do the fairly easy work of getting your IMEI cleared. Lots of people have been worried about devices not working on ATT because of this whitelist issue glad to see there are workarounds just wish ATT didn't make it so convoluted.
