Hello
new on here, and hoping someone can point me in the right direction please - I think my phone has developed an issue with it's IMEI, it will no longer register on any networks to make calls or send texts, although 3g internet works. It is a galaxy Note GT N7000 on android 4.1.2 and seems to have a generic 00499 IMEI number. I live in the UK
I've had the phone since new with my contract. I wondered if something happened after the last android update, or whether it has developed another issue. I didn't want to renew my contract, so when it expired I started using a PAYG SIM, and that has been fine for the last 3 weeks so I don't think my phone is locked. The SIM works in other phones so there is credit and network coverage.
It is unmodified, and I have never rooted the device, or installed any custom software. I read online that that automatic updates can sometimes cause Galaxy phones problems resulting in a default IMEI number. As I have only installed automatic updates through KIES and via my previous mobile network, I wondered if this has caused a preoblem, of if the phone is blocked!?
I would send it for repair but I don't live near any repairs shops :crying: I don't want to change the IMEI just restore it to what is on the label if that will fix the 'not registered on network' problem.
If it means buying a new mobile, then I'm happy to learn something new to try to repair it....just where to start?
thanks in advance :fingers-crossed:
My new Honor 6 H60-L02 doesn't seem to have a data connection. The telephoning/messaging works well, but when I am out of wifi range, and want to use the internet, the message I get is 'no network connection'.
Any help appreciated.
Sorted!!
It was my sim card settings, OK now.
Which settings you mean? I've got the same problem on h06-l04 and did everything like deleting the APN, tested APNs from other providers etc. - nothing helped. The SIM shows h+ and h all the time, but when I try to open a site or try to update my apps over google play the connection works a few seconds up to a minute and then the connection got lost again. It never happened on my galaxy s2.
I used the APN settings on my sim card providers web site and they worked perfectly. If I am not in a wifi zone the phone switches to h+ and performs very well.

What model do u have? H01, H11 - won't support Euro 3G, thay are only for China. H02 and H12 - should work fine with 3g. H04 - Should work fine with 3g and 4g in your country.
Also please check if your carier provides 3g service.

3G/4G issue
I'm also having the same issue with my Honor 6+ which i bought last month from dubai. I'm trying to use data connection using 3G/4G in india as i'm residing in India, but even after following all the required settings that are provided by my service provider and the other trouble shooting steps i'm still no where. It always displays the 3G/4G icon at the top but never works. I doubt if it is something to do with the software/firmware version. Please suggest.
I'm also having the same issue with my Honor 6+ which i bought last month from Malaysia and using in Bangladesh. I tried airplane mode on and off, it shows 3G for few moment or minutes but then again it becomes edge mode. Please help me out from this problem.. thanks in advance..
I live in India and I bought my Honor six plus online from a local retailer, and my phone can only access 2G data (or EDGE, apparently ) which is too slow to support anything. At first, I thought it was a sim card issue but I tried using the same sim in someone else's phone and that person's phone had no such problem. Even my brother's Iphone faced nothing of the sort. Any one know how to fix this?
Check on the back of the phone for phone number. On my honor 6, on the back on the lower part are 2 lines with text. on the second line I have found my phone model: H60-L2, in my case. Then you can check with, for example, http://willmyphonework.net/ if your phone model will work in your country. I know for example that my phone model will not allow 4G in all European countries.
If you prove that your phone is working in your country than its a matter of settings. You can try:
- Place the sim card with a data plan on the main sim tray. Honor 6 not rooted and running stable ROM will allow data only on the first tray. In Settings -> Dual Card Sim Management you can see which card is in which tray. If necessary switch the sim cards into the other tray.
- Check your settings and here the most important one is the APN. Make sure that the settings of your operator are correctly set in order to have mobile connection.
Generally the 3G network should at least be recognized, so if your phone is not registering with a 3G network then either it is not hardware compatible or you have placed your SIM in the wrong tray. Most probably is the first option and what you can do is to change the phone...
Man...i was having the same problem...well just 2 mins back!??
I have marshmallow update...and wat my problem was that the apn was set, though correctly, but in upper amd lower case....
And it seems apns are case sensitive...so check it!
Honor 6x is my latest mobile, which i bought a week before, it's seems like the mobile having data connection problems. till i'm using 4G sims but i'm not getting at least 2g speed, most of the time i'm not getting internet connections. at the same time it's showing H and H+ symbols ...
if possible, someone pls help me here.
Hello,
I am from India. I had purchased a Google Nexus 5 phone (Black/ 32GB) last year (December 20th, 2013)
I have started facing a serious issue since yesterday. My entire mobile network went down all of a sudden. Tried using other SIM but of no use. The same SIM works fine in other phone. Other functions including WiFi in Phone works perfectly fine.
A couple of things that I noticed are:
1) When I try to search for the Network manually, I get the message "Error while searching for Network".
2) I noticed that the PREFERRED NETWORK TYPE is defaulted to LTE. I cannot select any other option 2G or 3G.
3) When used Choose Automatically option - it starts with Automatic Registration and then flashes an error "Can't connect to this network right now try again later"
I tried doing a Factory reset hoping that it would work. But, no success. Have contacted LG Direct Service Center (since I bought it from retailer and not from GooglePlay store) and they suggested it's a PCB problem and it needs to replaced which would cost me around 12K INR. Which I am not ready for.
Please let me know what needs to be done. Any help is highly appreciated.
Regards,
Vijay

He's clearly not in airplane mode.
I have tried with all basic troubleshooting options, kindly check the attached screenshots. Please please help needed urgently.
I was going to make a new thread, but his problem matches mine almost exactly.
Hi guys, i have this problem for over a week now.. A very frustrating week i must say. I got this n5 about a month ago, my uncle got himself a G3 and gave his nexus to me.
Everything was smooth, amazed by the phone, everything working fine, happy as hell. It all crumbled when I went to spend the holidays at my brothers, where he lives my carrier doesn't work (everyone uses another one). When i got back to my house where the mobile network works fine it just stopped. All other sims would work on my phone and my sim work on other phones.
I gave it a time, thought it would be cause i spent too much time on my brothers and it would be ok after a while. It didn't. Then i started to worry and try to fix it somehow. First i got a new simcard (same carrier), no bueno. They told me to restore my phone and stuff, it didn't work. The phone has always that empty triangle, doesn't matter if it's 3G, 4G or 2G.
So I came to the internet look for help. I saw that some people had bring this to the LG, their response was to do a recovery with fastboot and then put 2G on the mobile network. For a moment i thought it was over, my phone finally had some bars !! But to my disgrace I can't make nor receive calls, i can only send/receive SMS and access internet thru 4G, not 2G as the support said. Oh, if i put 3G or 2G dem bars go missing and the empty triangle ****er appears again. Still, my simcard works on every other phone but now only one carrier works on my phone (not mine unfortunately).
Then I started looking on forums like this one and a whole bunch of others and tried many things, all of them unsuccessful.
I tried many things, maybe forgot some but will list those that i remember.
I tried to flash the factory rom. Then tried to flash only the radio of previous androids (tried too many of them to count). Dialed that *#*#4636*#*# or smth, put LTE/GSM, only LTE, activated/deactivated radio. Airplane mode on/off. Tried to recovery on fastboot again. Tried to make new APN. To finish my story, put a Cyanogemod rom and it also didn't work.
So now i decided to post here as my last shot before i go to that carrier that still works. Also, what guarantees that this carrier won't stop working like the others? I'm afraid that may happen. Further informations, i saw many people complaining about T-Mobile and other carries, but I'm brazilian, so it's not one of these. My carrier is Oi and the one that still works is TIM.
The two threads i got most tips were these and some sites in portuguese:

Hallo everyone,
What's up: my Nexus 5 can't make any type of calls.
The story behind: in march the memory chip of my Nexus 5 died, so I let it repair from the official LG support (it was still under guarantee). They changed the whole Motherboard and send me it back. At the same time, I received the new SIM card from my mobile network operator (o2 Germany) because I moved from prepaid to contract, but I still keeped my number.
Since the first day with the repaired Nexus and the new SIM, the LTE worked without problem and I could surf, but I couldn't make a single call. I talkd with the o2 Germany support, and they toldt me that It could have been a problem related to the number porting. After a few weeks the porting was officially completed, but I couldn't still make any call. Then after many weeks and many support calls, I had a so simple Idea...just let's test my o2 SIM on my old Smartphone (an HTC Desire)...and finally I could make a call! So I'm sure that the problem doen't lies on the operator or the SIM.
What's happen exactly with the Nexus 5 and the o2 SIM (here the Video): the LTE Network is full available, I call a number and appears "Dialing" (sometimes the screen turns black without any reason until I press the power button, but not this time), after seconds of absolute no sounds it shows the error "Cellular network not available". Of course I tried to call different numbers, but the problem persist and it still remains, even if I use another SIM from another operator.
I'm really concerned that maybe the problem lies on the Nexus 5 hardware, maybe the antenna, after a bad repair...but that's just what I suppose.
I'm looking forward for your opinions and support, thanks a lot!
Have you taken any steps to troubleshoot?
Seems the issue is the N5, as the SIM is working, but it is unclear where the problem lies. Have you checked the APNs, do they match the ones on HTC device? Maybe try reflashing factory image? Factory reset?
You said LTE is working, so it is not antenna, I think it is a software issue. Start by checking APN.
Thanks for your answer, I will consider the antenna as functional
I have been checking the APN Settings with the same o2 SIM on the two different devices (Nexus 5 and HTC Desire), they are identical, but the Nexus 5 got some extra settings.
As usual, with the Nexus 5 I can't call, but if I move the SIM on the HTC Desire it does. Just using the same dafault APN configuration. Those are the suggested configuration on the official o2 Website, but I would just stick with the default ones that already works (on Desire).
Any suggestion?
I would do a factory reset just a last choice, because I got tons of apps and data that needs time to be reinstalled.
Another info: the LTE Network on the Nexus 5 sometimes disappears, and then appears again.
Bump, any Idea about this problem and how I could fix it?
Hallo, I'm asking again for your support :angel:
those last weeks I couldn't get rid of the problem with the calls, and I'm still clueless about how I can fix it. At the end of the month the 2 years guarantee expires, so I need to hurry up.
Summary: SMS sometimes comes later als expected, sometimes LTE Data doen't work, most of the times I can't make calls.
What I have already done:
- already moved my main SIM (o2 Network) from my Nexus 5 on an old device, and there I have no problems at all, and I can make all the calls that I want.
- already checked the APNs, they are all on defaults settings and are ok.
- already tryed to use a fully functional SIM from another network operator (TIM Italy) on my Nexus 5, even if the Network is fully available I can't make any single call.
At this point, I'm pretty sure, that the o2 SIM and the o2 Network itself works fine.
Today I have done a factory reset after a full backup on my Nexus 5. With all default an no extra app there's no improvement at all, call function works only a few times, most of the times I got the Network but the call function doesn't work properly... here just a frash Video about it:
https://drive.google.com/file/d/0B0yEcZCOozgkdmdjZWs0bkdIUnc/view?usp=sharing
After this try the LTE Network has disappeard (here a Foto) coming back only later as EDGE Network.
Could be maybe that after the Nexus 5 repair in march, the Device was assembled incorrectly and the Antenna have an unsteady contact?
Isn't the IMEI stored on the motherboard? If so, its possible you got a motherboard with a blacklisted IMEI.

I don't think that the officially LG Support (that replaced my Nexus 5 Motherboard im march) would use Motherboards with blacklisted IMEIs. Even if my motherboard had a blacklisted IMEI, then I shouln't be able to make any single call, but that's not what happens, because I can still and receive calls sometimes.
Well then I think you already know the answer. The warranty repair wasn't successful. You've eliminated everything else except the phone, and it used to work before, correct?

Yes, sadly seems that the problem lies on the unseccessful repair. Could you reformulate your last sentence/question? I didn't understand what you you mean
Is your phone switching to 3G while calling ? Because afaik, 4G can't be used to call someone.
So I suggest you to force your phone to stay in 3G and try making a call.
When I try to make a call with the LTE (4G, with full coverage showed), the call doesn't succeed (look at the last Video that I posted) and just after this the Network disappears and shows "Mobile Network Not Available" (but this doensn't happen always), then a few second later the LTE is available again.
When I move from LTE to 3G there's no Network available, and the call just doens't work. Same with 2G.
Update: I received back from the LG repairing my Nexus 5. In order to fix the problem with the calls, the entire motherboard was swapped. I didn't received more detailed informations about this fix, but right now it works again greatly.
Hello everyone, im new here kept searching everywhere for solution for my problem without any success. In may 10 i bought SM-G955N KT module, it was working great with 2g / 3g / 4g / LTE / LTE+, i went out of usa for almost 3 month and when i came back my phone doesn't work well with tmobile, i can send msgs use lte internet but i cant do calls at some areas, some times i have full lte bar and when i try to make a call it goes to 0 signal bar, i called tmobile many times about the issue but no solution i found out that they did upgrades to their towers in the period i was out of usa from may to august, right now i cant use the phone as any normal person its been a month that i cant use the phone at my house and some areas, i can make calls sometimes if im at different tower locations. Question is, is there any solution for this problem since tmobile did those tower upgrades its screwed up everything..... should move out to att or verizon or what should i do. I really need help with this problem its been a month, any solution would be welcome if it requires root or not i dont care i just want to find a solution for this,
Thank you.
Have you tried resetting your network settings and/or getting a new sim card?
Its not the sim card i already changed it to a new one also i tried it on a iphone 7s plus and it works fine, my phone is bone stock no root no custom software alsi its the korean version when i looked around i found that tmobile did some network upgrades from may to aug and thats when my phone got screwed up, i was albe to play with the ims setting and i got the phone to recive calls but i cant make calls, does my phone screwed up because it has the korean csc and the stock firmware or whats going on here
I'm not quite sure I understand your experience. From what I am reading, you went to Korea, got the G955N (which I bought for both myself and my wife), and then came back to the states and can't get it to work with T-Mobile?
I tried to get mine to work with T-Mobile and have experimented extensively with different CSCs and ROMs.
I eventually went over to AT&T
I've also had a rather extensive experience of how to get 4GLTE working here in the states with AT&T.
Feel free to reply here or DM me if you wish.

Hello thanks for your input, actually i bought the phone in the box brand new from amazon, it came here on may 10 i used it for 7 days 4G LTE 3G works great then i had to go out of country for 3 month i came back at the end of august to find that tmobile did a huge tower upgrades in my area, since i came back i wasnt able to do calls and receive calls, i was only able to text and use LTE internet but not calls, i went to different towers area and i actually was able to make calls but not in every area because some times my signal bar goes down to 0 or even 1 signal and i cant make calls still but my other friends who owns iphones or usa version of android works fine except me. Yesterday i edited the IMS setting im still on stock fw and i enabled every single feature there and i was able to receive calls in my area but still i cant do calls, i wanted to make sure if im gonna follow the steps here in this guide i will be able to use TMOBILE CSC with the korean stock firmware and get the features of tmobile as VOLTE and WIFI CALLING etc with the right CSC for sure and without tripping knox
Thank you
Hi, I did some extensive searching and was not able to find a solution for this.
I've got the SM-G955N, and ran into the same issues as other users in this thread with T-Mobile, has anyone found a workaround to unlock the LTE bands necessary to make the SM-G955N work with T-Mobile?
I didnt find solution yet too, i dont know what to do i gave up i tried everything on the official software no root.

I had a phone with the Korean CSC as well, N phone as well. I left the CSC alone and it worked with T-Mobile and ATT here in the US just fine, last fall.
I later changed the CSC to XXA, and still works well. Just tested it this week with T-Mobile, and it's working. I have to say, that locally, T-Mobile has much poorer spot area service than ATT. Kinda puzzling, but that is the way it is.
My phone is rooted, so it make things a bit more handy to mess about and return to my previous setups.
