I bought my n7100 on taobao here in China, and it's a Korean version. I put my China Mobile sim card in, and it makes and receives calls, and text messages and can use wifi with no problem.
The only thing is the mobile data doesn't work. I rooted and tried tweakker, and HiNet, to reset my APN and MMS settings, but that didn't work. My phone still thinks I'm roaming.. it displays
this message "Data Roaming, You have lost data connectivity because you let your home network with data roaming turned off".
I've also tried updating the APN and MMS settings manualy with information i've found on the web.
I've googled and searched this forum and I can't find much. I thought it would be an easy APN settings fix but it seems not to be...
I took my phone in to the local China Mobile store they couldn't fix it. I took it to a local android expert here and they didn't know what to do.
Any ideas would be greatly appreciated.
If you bought a Korean Note 2, you don't (shouldn't) have an N7100. I also purchased one through Taobao.
You should have an SHV-E250S, E250L, or E250K. Which one do you have? Check the baseband version under Settings > About device page.
No matter what, you're going to be limited to 2G only with China Mobile.
You're right, It's SHV-E250S, and I'm fine using the 2g in China on China mobile, but I'd just like to know how..any help?
Baseband Version is E-250SKSVLJK
Try removing all modifications to your APN settings.
Next, go into Settings > More settings > Mobile networks > Network mode and change it to GSM only. Also make sure that Data roaming is not selected. Run a new scan for network operators while you're in there to refresh your APN settings to the right ones.
In data network mode I only have 2 options "3g only" or "LTE Preferred" I have it on 3g only. I have now unchecked data roaming, but I don't see any place to scan for network operators. I have included a few screenshots here, sorry i don't know how to insert them.. http://tinypic.com/r/2198djn/6 http://tinypic.com/r/24dhfmx/6 http://tinypic.com/r/2zof98w/6
Now it's obvious why you don't have data. Is this the stock Korean ROM? Are you rooted?
I can point you to a decent ROM that will fix all of this, provided you have the patience to fix it. It's relatively easy.
Yes it seems to be the stock Korean ROM. I am rooted using http://forum.xda-developers.com/showpost.php?p=31801060&postcount=2 I'm more than willing to flash another rom. I've put about 20 hours into this so far, I imagine I can muster enough patience to finish it
Once they give us a damn Korean Note II section, this kind of information will be a lot easier to find.
Try this ROM for now, it's the one I've been using for a few weeks and I love it.

Thanks a lot the rom (715mb) is downloading now, I have tried to flash ROM's on my old galaxy nexus, and on this note II, but I never succeeded, can you please link me to a good guide, on how to flash this rom? thanks.
Odin is included in the download. If you're using Windows 7 you may or may not have the drivers for the phone, and can grab them out of the All-in-one Toolkit. Just installing the toolkit should install the drivers necessary.

The ROM you're downloading has two files and two pictures, as well. Open the pictures and follow along. All you have to do is click two buttons, select two files, then hit start. It WILL wipe your phone.
I installed that rom you suggested, I went into settings and did GSM only, and had it automatically find my network (china mobile) selected it, rebooted, and still it says i'm roaming so there is no connectivity... any more ideas?
Can you try somebody else's SIM?
There's no reason you should not be getting service unless something is not right with your SIM or phone.
I installed the rom you suggested, i went into settings and made it GSM only, also had it automatically correctly locate my network (china mobile) and it said "registered on network".. but it still isn't working, same problem, it says no connectivity cus i'm roaming.. any ideas now?
my gf will be home from work in a couple hours, I can try her sim card then.. my sim card was cut by me for my old iPhone.. is it possible or likely that the phone can still make and receive calls, but that somehow data connectivity was affected by me cutting the card? also one guy at the phone fixing store tried his sim card (from another company) and internet worked fine he said..

China mobile have various sim plans, from local to province to national. Are you using the sim in the same city in which you bought it? If not and you don't have a national plan, it could be why the phone is showing roaming. In China going from one province to another is already considered roaming unless you have a national plan. This is from my experience back 2 years ago. Also, you best check at a China mobile shop if you have data activated, gprs/edge is not activated by default, you need to ask them to do it.
I would advise you to switch to China unicom as they have 3g/hspa which is much faster than china mobile.

For clarfication, I am in Hainan, and the card is from hainan. I use the same sim card in my galaxy nexus without any problem. I tried my gf's card just now, it didn't say any problem with connectivity, and did not display roaming.. And it shows the G symbol (for 2 or 3 G I assume), and has up and down arrows next to it.. but it doesn't actually work for browsing the web or using apps over the data network.. I even reset all the APN settings and let it automatically find the China Mobile network, but it didn't help.. what if I try to set the APN settings manualy? and any other ideas??
Showing the G symbol is GPRS, which is 2G. You will not get 3G on the N7100, N7105, or Korean model Note 2 on China Mobile.
Sounds like you need a new SIM card. You can try to set the APN manually to make the data work with hers. I've never had to set an APN manually and I've used many phones here with all 3 carriers, so it's a bit odd to me. No clue why your card doesn't work, but since hers is working fine, it's definitely not your phone.
For the record, her card displayed G, but even after messing with settings, I couldn't get it to have working data network..
Today I bought a new card, and had it officially cut to size, put it in the note II and it's still telling me no data connectivity due to i'm roaming.. i'm so frustrated
edit: after restarting a few times and trying to automatically make it register on china mobile .. it worked on the 4th attempt.. it still displays data roaming, and I had to enable data roaming... but now it works, even though it says i'm roaming?? wtf
Ive the same problem with my Korean galaxy note 2 all voice service work perfect but when I tried to turn on data it says insert Usim Card to access network please help
I rooted my S4 Mini (SPH-L520) phone using the procedures found here: http://androidxda.com/root-samsung-galaxy-s4-mini-sprint-sph-l520
This allowed it to be flashed to Boost. Talk/text/web/MMS all work.
However, I have three problems that appear to be related to the phone thinking it is still on the Sprint network:
First, I keep getting a sim card error that says, "The network did not respond in time. The SIM card has locked. Please power cycle the device and if the problem persists contact Customer Service.”
Second, I keep getting a "MIP 67" error.
Third, I can’t get a WiFi Hotspot program to work. The programs will start, but within a minute I get "Unable to connect to data network, turning off Hotspot. Your plan may not have the Hotspot service. Do you want to see subscription options?" If I click OK, it tells me "Network is not available." and ". . .dial *2 from your Sprint phone or call Customer Care. . ." Tethering with Boost worked fine with my old phone (TP2).
Is there anything I can do to fix these problems?

I saw something about changing APN settings on a GSM phone. Does that apply to CDMA phones as well, and might that provide a solution?
I'm getting the same errors, 67 and 89. It thinks it's still on Sprint, it was already running on PAGEPLUS, then lost it.

Hi. I'll simply explain what happend.
I went by plane. I switch my phone on to airplane mode, but when I switch it back phone can't connect to my home network.
It detected networks and can connect to the internet but I can't make any call or recive it (the same with SMS).
It show Me the error message - Mobile Network Not Available or just simply Call ended after two beeps signal.
Show me yellow triangle on the top notification bar and message - No service, Selected network unavailable
I checked IMEI - it's correct
I used PC Companion tool to Repair My Phone - doesn't help
SIM card work well in other phone
other SIM cards - the same problem - not working (I even tryed SIM card from different country network operator).
Phone has no SIM lock
Back to factory settings doesn't solve the problem.
Any ideas what going on with my phone and how to fix it? Please
Model: D5503
Android version: 4.4.2
Build number: 14.3.A.0.757
So it did work before in your home network?
Or is it an issue with a new phone?
Sounds strange to me... If your SIM works in other phones, it can't be a provider issue.
I can't imagine that it is a software issue since it keeps happening after a factory reset.
If it's the hardware it is a warranty issue...
But maybe somebody has a suggestion for you.

I had some unusual problems with an inability to xfer data over the mobile network (as opposed to the WiFi) on my wife's Z1c, after both had been fitted with what seemed to be brand-new sim cards by the local T-Mobile store, and I found that in:
*Settings
*Wireless & Networks: More
*Mobile networks
*Access point names
...that she (somehow) had an access point name of "epic.t-mobile.com" as opposed to my APN of "fast.t-mobile.com"
So, I deleted that, and selected "create default APN", and fixed the problem.
There are other settings in that same menu, such as "preferred network type" that might be messing you up.
She could make calls and send texts with this problem, but had no internet unless she turned on WiFi.
But I cannot imagine what would be re-provisioned by switching airplane mode on and then off.
Perhaps you need to declare your sim card a dead parrot, and get a fresh one from your service provider.
This is pure speculation, I have no evidence or experience, just guessing at things that MIGHT cause such a symptom.
Hi Team,
I have purchsed a brand new Xperia Z1 from a retail store.
I am having problem with mobile network connectivity, its not behaving in normal manners.
Many times it drops network and many times it gets auto switch off in a single day and I need to restart it 2-3 times in a single day to make it work properly.
Many times it happens that its showing full network strength and when somebody calls me it says that this number doesn't exist, this is not a simcard issue as my sim is working perfectly when I use it in any other mobile.
I have already given it to sony service center two times and they use to say that softwer was required to be updated that's why you were having network problem but its not resolved yet.
Its is very costly mobile phone and as of now I can't afford to buy any new phone as I have spent my whole savings to buy this phone.
Can you please help me?
Thanks in advance.

Solution:
I struggled for 2 days to resolve this. And the solution was so simple. I resolved the issue accidentally.
Besides following all the recommendations (except the hardware part) on different online forums I was exhausted. Doing nothing, I started making a backup of my cell phone with an idle mind. And there I found an option to reset your network. I have Sony Xperia Z3 Dual. You should try this.
Go to Settings -> Back up and Reset
Scroll down
Go to "Network Settings Reset".
Then reset your cellular network. And bingo. It worked for me. I was able to make calls and use my cellphone in normal mode.
Please let me know if it worked for you. I can guide you for some more tricks.
Hi,
I recently went to India and thought it would be cheaper there to get my note 2 unlocked but, the person who tried unlocking my device got mad at me as my phone was rooted. He said, everyone wants to be a developer nowadays and thus it made his job harder. He asked me the model number of my phone as it shows GT-N7105 because I have DN3 v 5.2 installed but it is actually sgh-i317m from Telus in Canada. He gave up and said he was unable to do it. After coming back home, my original sim that I have been using in the same phone, does not work anymore. There is no network. My wife's sim card, which is from another provider, works now though it never did before. I though there could be something wrong with my sim card so I tried it in an old phone and it works perfectly in it. What would you suggest, I should do to try and resolve this problem? I am thinking of erasing everything from my phone and factory resetting it. Eagerly waiting for your expert suggestions!
Just to add: I chose factory reset option from under the settings menu and wiped all my data but it still does not work with my sim. I also, went under the available networks settings, chose the option to search networks and then selected mine (telus) but it say's no service (telus) not available. There is another message in the notification bar, which reads "data roaming: You have lost data connectivity because you left your home network with data roaming turned off". I am not sure if that tells you something related to my problem but I though I should mention that as well.
I am having an issue with a phone I recently bought on eBay to replace my wife’s phone – a Samsung S3. After researching, I selected one that appeared to be compatible to our carriers’ network – AT&T. It’s a new factory unlocked LG G4 model US991 running Android 6.0 that arrived in a sealed LG box. I moved the sim card from the old phone to the new one, but I initially couldn’t get it to connect to our network. A call to AT&T customer service didn’t provide much help although they had me check the usual things when transferring a sim to a new phone. They advised to go to my AT&T store for help in getting it to connect. They were also unsuccessful after checking and verifying several things (not really sure what). They concluded that the phone must not really be unlocked as it was advertised.
Frustrated with that, I decided to try contacting the eBay seller about the issue and was happy to get a fairly quick reply, telling me to change the following network settings:
Select Mobile networks
Network mode – GSM/UMTS
GSM/UMTS settings
Network submode – Legacy 3GPP multi
Network operators – after choosing Search – found AT&T, RAT:WCDMA
And it worked - voice and texting both functioning well – and most importantly my wife was now happy. But it didn’t take long to realize the reception wasn’t nearly as good as my old Samsung S2 on the same network. We were in a rural location recently and where my phone was showing a decent signal, the G4 barely showed any and sometimes none. I also noticed that no matter where we were located, there was never an indication of a 4G connection in the home screen icons. So I then tried changing the network connections to the following that resulted in the 4G icon displaying but unfortunately voice and text stopped working completely (got an error message – no SIM card or SIM card error):
Network mode – LTE/CDMA
I also set the APN to NXTGENPHONE and its' settings according to the AT&T website
I’m hoping there’s something I can change to improve the connectivity/reception on this phone since my wife really likes everything else about it. I would appreciate any help/advice you could give.
Thanks

Confirm with AT&T that they tried one of their latest AT&T LTE capable sim cards to see if the issue is in the sim card you've been using. If not get them to try it.

What is your signal strength on both Samsung and lg?
Download an app called advanced signal status on both phones
What is the db? And signal stength?
One should be a minus one should be a plus
They will also fluctuate so give me the number it usually sits at

OK - Thanks.
If your IEMI is not registered on their network (likely, as you didn't buy the phone from them), see if they will register it. May require that you buy a new LTE capable SIM card from them.

That is a very weak signal.
Here's the catch
Both phones should have displayed the signal strength
So you are using 2 different network bands on the phone
It's either your sim, or select another band on your LG G4
2G/3G that your phone is currently running on is an older network, and since your Samsung is not registered on that network you have selected wrong band on your LG G4 or your sim card is not compatible to operate on the network you want to be on

I have several ideas for the reason of your problem. First of all, is everything ok with your SIM-card? Wasn't it damaged when you installed it in the new phone? Also your type of card can be not suitable for this certain phone model, unfortunately that happens sometimes
I'm really surprised that the customer service wasn't really helpful in your case, as I know they should check such cases personally in special centers and fix the tech problems. I recommend you to call them again and ask about this
And nice 4G connection demands a constant good signal. It's a rather common problem for the phones but not because of the bad networks but your current location, there are many places where this signal is very weak I had such problem in my house, I ended with buying a signal booster https://www.myamplifiers.com/4g-lte-booster/ which in my case was really helpful. However I suppose that your main problem isn't the signal but your phone, I think that you really need to check it in a special service center because all these problems mean nothing good for your device, especially the new one
I am merely speculating but depending on how old your last sim card is, it could just be as simple as getting (here in Canada they're like $5-$10) a new up to date one. It could also be an issue with the phone antenna itself?
Network mostly recovered
Just install advanced task manager from play store and set it to kill task every 15 min or so. Network issue will be gone. This is what worked for me. Thanks.

Hey... I had this similar problem. I bought an Iphone 9 and and I had many problems with my signal. In many times, my cell phone showed "1 bar" of 4G, so I couldn't do almost anything. Fortunately, a friend told my about an signal booster and now my signal problems are done. I bought it in a website named amplificadordesenal.es and it's been really GREAT!! it cost a little but it was the better solution.
Hope this can help you
