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
Hi Guys.
So received the phone on Thursday, Friday I did a sim swap from my normal sized sim to a micro sim. I waited the whole day but the phone didn't have any network access.
Today when I woke up I I switched the phone on hoping that everything will be fine, thinking the simswap just hasn't gone through yet, still no network access. I took out the swim from the phone and switched with my ipad, the sim was working in the ipad, and the ipads sim also didnt give the phone network access.
In the top right corner it shows full bars in grey, cant make emergency calls or anyhting.
In the about section of the phone, I have ALL the details present, baseband version is there, kernel version is there.
In Status section, network is unkown, signal strenght is -83 dbm 15 asu, network type unkown, service state is out of service, and the rest is also present.
I thought the phone didn't properly register to a network, so went into settings - wireless networks - more settings - mobile networks, but it gives me a insert sim card message.
The phone is reading the simcard fine because it asked for the PIN when switching on.
When trying to make a call I get, it says "Not registered on network"..
So what am I to do? Vodacom can only pickup the phone and exchange it on Tuesday, so was hoping that this might just be a software issue that can be resolved by a flash.
I have tried resetting / hard resetting the phone numerous times.
Its the Note 2 N7105 LTE Version
Any help would be highly appreciated.
Wrong forum.

Great thanks.
I tried this but didn't solve the problem. I am using the same sim that I received from the carrier with the phone they shipped.
I have played around in the menu however, maunally setting the band and so forth, just restarted and started receiving sms, so basically if not for your post I would not have solved this.
Thanks
I have isolated the problem.
In the service menu - UMTS - DEBUG SCREEN - PHONE CONTROL - NETWORK CONTROL - SERVICE DOMAIN
There are 3 options
1 CS + PS
2 CS ONLY
3 PS ONLY
CS seems to be for making calls and sending smses
PS seems to be for data connections (When this is selected, the bars are replaced with a circle with a stripe through)
I Could be wrong with the above, so anyone with experience please shed some light
Those 2 work seperately, but when CS + PS is selected, none of them work? Very odd, anyone know what the issue could be?
anyone?
Its a unlocked TMobile samsung galaxy S2 (SGH - T989) from US which I am trying to use in India. I had bought it from t-mobile as part of a 2 year contract. After completing my two years contract, I got the phone unlocked from t-mobile before coming to India. The phone worked fine for first 15 days here in India but stopped working since then. I have tried many different SIM cards from different Indian mobile service providers. These SIM cards work perfectly fine on other handsets . *#06# shows correct IMEI which matches with what is printed on the back side. Phone shows signal towers with varying signal strength. I could see the signal towers even after disabling Wifi and location services but when i try to make a call, it says "Not registered on network". Wifi, if enabled, works fine though. When I try to select a network operator from Mobile networks menu, it does say registered to network occasionally but mostly it fails to connect to any network (i have tried both manual and automatic selection) but even if it says registered to network, when i try to make call, it says not registered on network so I am not able to make any calls at all. I have tried factory reset and upgraded to JB 4.1.2 (radio: UVMC6) but problem still stays. Please help me.
Did you try entering the correct apn ? Similar thing happened to me but i took it to the sim card company and they entered the apn manually and it worked.

I did try APN but I believe that is for GPRS/EDGE and 3D and these will take effect once cell network is established.
Hi there. Recently my Nexus 5X has something wrong with its communication function.
I am using CM13 nightly builds with ElementalX kernel on 4GLTE network. And everything works fine except:
When making calls, it ends up with "Network not available". However, the signal bar is full. Also, it is unable to send or receive any text message.
I have already tried:
1. Flash the latest factory image from Google(mtc19v). And it worked for a while then the issue recurred.
2. Dial *#*#4636#*#* and switch to "CDMA only" but it failed to make it, automatically rolled back to LTE mode.
3. Tried CM13 snapshot and other nightly builds, and still got the problem.
Does anyone have any advice? Thanks.

Try getting a new simcard from your carrier.

Thanks for reply. I will try ASAP.
OK. I have fixed it. This is the MOST weird and tricky problem I have ever met since I knew Android phones.
First there are some key concepts:
From the "*#*#4636#*#*" (Testing) menu -> Phone Information, we notice IMEI, Phone number, and Current Network. In my case I couldn't make phone calls or send/receive text messages, I got my IMEI and Current Network NORMAL, but I got NOTHING for my Phone number section, which means my phone turned into something without a number! So how can it be discovered by the mobile base stations?
Furthermore, scrolling down there are another 3 indicators: GSM service and GPRS service and Network type. In my case the GSM service was "Emergency calls only"(However there is someone on the Androidcentral Forum said his Nexus 4 under the same circumstance can't even dial 911), and I doubt that. The GSM service was COMPLETELY offline. On the other hand, since my data service ran smoothly thus the GPRS service is always "connected". The Network type is "LTE". I have tried many times to change it to the CDMA or GSM ones, like "eHRPD", "1xRTT", "EDGE" or sth else but few succeeded. Once succeeded, I can normally voice or text, yet on the outdated network.
Then how I fixed this:
I googled "Mobile network not available" and got many results about the Samsung phones. Then googled "mobile network not available nexus" and found this one "Mobile Network Not Available" on Nexus 4 T-Mobile which perfectly matches my case. Finally I thought it had something to do with my network provider and my phone should not be blamed. I just tried another SIM card from another carrier, which worked perfectly on LTE network with voice and text. When I opened the *#*#4636#*#* menu and tried to change "preferred network", the phone also worked smoothly no matter WCDMA only/GSM only/LTE only. I put back my bad SIM card and the voice and text came back!??? I was extremely confused. That is to say, still there was a problem on my phone. By inserting another SIM it just did something like refreshing the stucked radio module??? I wondered. After this simple trick I got my voice and text back though, the "Current network" became "Roaming Indicator Off".... Maybe the next time.
