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.

Hi All
I bought my galaxy note i9220 in China on 18th Aug. It is a genuine phone, NOT a clone just to note.
It was working perfectly fine when I was in China using a China Mobile SIM card.
Last Sunday I went to hongkong to catch a flight to London, and when I was in Hong kong, I changed back to my UK 3 SIM card, which again, was working OK in hongkong.
Before flight took off, I switched the phone off.
During the flight, I must have hit some button and accidently switched the phone on ( as when I landed, I took my phone out and it was “ON” with no signal).
Ever since I landed in Heathrow, I got no signals. The phone shows I can only make emergency calls.
I have tried all of the below but none worked:
1) Switching the phone off & on.
2) Take out battery (while phone was off) & SIM and put them back later.
3) Take out battery (while phone was on) & SIM and put them back later.
4) Reset to manufactory status.
When I go to Setting – Wireless & Network – Mobile Network – Search operator, I can see “3” in the list of operator, but when tried to connect to it, it said “Unable to connect to the network”.
The “3” sim worked fine in my old NOKIA phone so I don’t think it’s a problem on the SIM.
Anyone able to help? Thanks sooo much!
a suggestion..try to make sure you inserted the sim card with the bend angle facing the bottom of your phone..sometimes you insert your sim in a wrong way and this cause your problem..am not trying to be funny but it happen with quite a lot of people including me...
or Could be a fault on your phone..and these things happen..
or your sim is invalid for a reason..i suggest to get a pay as you go 3 uk sim card and try it ...or call 3 customer service and speak to one of their agents to have a look at your account ... they might send you another sim or pop in one of their stores and speak to someone about it...if nothing wrong with your account then am afraid it is a hardware issue with your phone..
Are you sure the phone is not a 4G phone?
This won't work in the UK as our Cell's are different as well.

Got my mum called the phone provider back in CHina they said it should be ok to use in the UK.
They asked me to check my SIM freuency (or sth like this). and said as long as it is on GSM900/1800/1900MHZ, then it should work...what is that???
Try change your network settings between the options, gsm, hspa, and wcdma. Think it's settings, more, mobile networks, network mode.
Probably one of those should sort you out.

Thanks.
When i went into the"mobile networks", the phone started auto search of network.
And it returns network lists:
3
O2 (forbidden)
Vodafone (forbidden)
I understand the 2 being forbidden as im not a custmer of either O2 or VDF, but it just does not allow me even to connect to 3..grrr very anooying.....
I will try changing the settings when i get home today.

THere is no network mode in the mobile network ....how can i change the mobile network type in the SGN?
Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!
Sent from my ZTE V967S using xda app-developers app
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.
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, I have an issue with 4G after the last dec update. In 4G/3G/2G auto connect mode, usually the receiving data arrow ( v arrow below the 4G symbol in notification bar) gone missing and thus the connection got lost. Only transmitting arrow is visible (the ^ one). I have to wait for some minutes or turn to flight mode and back to get my data connection back.
In the beginning I don't really sure this issue is caused by the latest update, but after I tried nearly everything, including factory reset which is doesn't help, I think that the update is the problem.
I have tried my sim on another phone and it worked normally. I have tried another sim on my note 8 and it got the same problem.
Oh and this is only a 4G issue. My 3G works normally. And before the update, I never experienced this kind of problem.
Two of my friends got the same note 8 and one of them is also using the same carrier as me, but neither of them experiencing this issue.
Anyone can help?
Thanks in advance
I had this issue too, it seems 4g connection only got the problem...,
Problem solved, they replace my device
I have the same problem but seems like in a different way, when I got the phone first time I contacted my service provider to activate the 4G service cause it was inactive on my line due to provider's issues, anyway the phone worked on 4G for only 2 days, after that it kept working on 3G, I contacted the service provider many times but they have no issues with my SIM or handset.
I still don't know what is the problem, is it a hardware malfunction? Is it an installed app? Is it a Samsung Update? I don't know!
have tried getting a replacement sim card, I had same problem in the past and they had by mistake sent a sim that was not 4g, got replacement and problem solved
Well, the problem is that it worked at the fist time on 4G so the SIM was 4G not 3G, but I have just comeback from their store, at the first the technical support did something in their system and switched the phone to airplane mode then turn the network ON back and the deice worked on 4G but after a couple of minutes the phone switched to 3G without going back to 4G, then he advised me that this problem either a SIM or handset problem and it's always 90% SIM problem, so we changed the SIM card and the phone is working on 4G for around 30 minutes till now, I hope it will keep working on 4G
2 days and phone is still working on 4G, it was a SIM card problem
Aoa dear
