stock restored issue remains. do u have any suggestions?

APN
You may have lost/wiped your APN when you did the root. Check under your network settings for mobile network and then look for apn or access point names. You should have one or more APN options, if you don't, then you may need to manually enter yours.
APNs vary based on your carrier, so you'll need to either contact them or look them up on the internet. I'd be happy to help search if you tell me your provider.

My network provider is TATA DOCOMO. Actually what happens is if i try to connect , suddenly range disconnect after 2 or 3 seconds range will come.
Again i will do restart or airplane mode , first time range will be shown suddenly range disconnect. strange problem. i dont know whats the problem. i dont know how to explain. i checked the APN it is fine. Is there any problem in my RADIO?

With Reliance CDMA the problem was an unregistered MEID. Are you on CDMA or GSM. Tata are known to be the toughest on security, so must be some setting which got hit for six.

[Q] how to get the GSM network working??

smthn went wrong with my SGW and since then when i turn my network mode into "GSM only" it doesnt connect to my service provider (instead of writing the name of my band it writes 'emergency calls only) inspite of the fact that the network icon in the status bar is showing a present network

Telco provider ?

whats meant by telco ?? (im from egypt so idk the meaning of sm words )
my provider supports GSM and i used to work on it alot since the 3G consumes more battery but my phone crashed once and since then i cant get the GSM working even after getting a whole new stock rom

You set up APN for your Service Provider??
Settings/Wireless & Networks/Mobile Networks/Access Point Names
Here you need settings from your provider, to allow you use Mobile Internet, MMS
Usually, these are there, in Stock ROM.....but, not necessarily with new Custom Roms.
Perhaps these are missing, if so, you need to contact provider, or check on-line with provider. Settings can be sent via SMS from provider.. ..otherwise need to be entered manually!!

i already did it before and its working very well on the 3G but the problem is wn i get on 2G i cant access network or even make ordinary phone calls 'only stuck with the emergency calls only'

btw the pic i sent is wn im working on GSM (2G) while wn i work on 3G it tells me me band name instead of 'emergency calls only' and on 3G i can access network and make phone calls while on 2G i cant do these stuff
ive also changed the SIM card to another provider and its still exactly the same issue

[Q] Why Does my Korean N7100 think I'm roaming and not connect to mobile internet?

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

Did you already try menu options? There's some things in there where you can choose network operators, etc. You usually shouldn't have to, but if you're having trouble it might be worth a try. Only other thing I can think is sim card not sitting right or not activated properly.

Check that the sim is seated properly in the holder.
Do a factory reset on the phone.
In the set up process it will ask you to choose a provider. This puts the correct APN settings in the phone.
If you don't want to reset the phone, then google the APN settings for your provider and enter them manually.

Connect to wifi first. Then download the cell provider settings - it's under network area, called "Internet Settings" and says "Download settings for Internet and MMS."
If that doesn't help, go under Mobile Networks and tap "Service providers". It will scan for cell service in your area and let you manually register on the network. ( I have done this a few times lately, as my phone doesn't seem to want to stay connected to T-Mobile.)

Question How to change preferred network type?

I'm on EE UK but the preferred network type setting doesn't appear to be present in SIM options?

It appears that some providers suck hard and don't want to allow you to switch networks. That's not a phone thing-y, it's a provider thing-y. Which means that your phone will of course still change networks, but only if the "higher" one is not available, ergo your phone will only connect to 4G, if 5G is not available - if the 5G connection is bad, that will probably cause problems for you, because your phone will probably not want to connect to 4G automatically.
I can easily switch preferred network types
Settings -> Network & Speed -> SIMs -> (scroll down, between 4G Calling & Carrier settings version) -> Preferred network type (5G, 4G, 3G, 2G).
It that's not available, your network carrier sucks. No more to say here.
I'd suggest you either switch providers, or contact your provider to see if they are willing to change this. It's definitely on their end, cuz people like me can change the settings easily.

You may be able to change preferred network type with *#*#4636#*#* dialer code.

EE (& BT Mobile) hide the menu.

Or you could just make sure Adaptive Connectivity is enabled and not worry about it.
You would have to drag me away from EE (BT Mobile) screaming and kicking given the coverage and speeds they have, to say they suck over one menu option missing is absolutely laughable.

When the Note 20 first came out a lot of carriers wouldn't let you change network type but there's an app in the play store that was working on the notes.
Force 4G/5G Only - Apps on Google Play
Lock your phone to 4G/5G mode or VoLTE network

Crashes or alternately just disappeared for me when I click on the first option "4G LTE with only one SIM". Reported the crash. Thanks, though. Maybe they'll update it.

An alternative to the dialer code is to boot into safe mode, and the preferred network type setting will appear in: Settings -> Network & internet -> SIMs between Data warning & limit and Carrier settings version (at least it does on my Google Fi Pixel 6 Pro).
