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 all,
My problem is that my Galaxy S3 (i747M) cannot make or receive phone calls*, but I can send or receive most SMS**, and my LTE data is fine***. I've tested to ensure it's not my account with Rogers, or my SIM card. I took my SIM card and put it in two other phones, and both worked just fine (one Rogers, one Telus). Putting their SIMs into my phone and the same problem as with my own SIM in my phone. I have unlocked my S3 using the 4.2 trick, but I didn't have this problem back then. I'm assuming this isn't causing me issues now.
I used asterisks because each of the above has some additional details:
* I cannot reliably make and receive phone calls. For example, I can try calling the same phone number (home) 10 times, and it may only go out once. From my home phone I can try calling my cell phone 25 times and only get through once. Every time my calls out fail, it either sits at "Dialing..." for 30 seconds before ending in "Call Ended 0:00" or just immediately drops the call without the 30 seconds of "Dialing...".
** Most of the time I can send and receive SMS from any other cell phone. Occasionally a message won't send out even though I have 4/5 signal bars. Resending the message works. Not sure if this is related to my issues with calling.
*** LTE data is fine (using LTE APN). Switching away from LTE to just 4G/H+ and data is a bit spotty. Sometimes it connects, sometimes it doesn't. LTE always connects just fine.
I've tried all sorts of flashing and reflashing:
- problem started when I was on S3Rx 4.0, but I never thought much of it because most calls went through fine
- problem got worse when I was on Lollipop (CyanideL), progressively so
- used Odin to flash stock NF2 (downloaded from Sammobile site), was no different than when I was on Lollipop (CyanideL)
- used Kies to flash stock N__ (forgot exactly which one), still no different
- flashed different bootloaders and modems
- while in stock NF2 firmware, went into *#2263# and made sure it was set to Automatic.
So any ideas what problem this is? I just find it extremely odd that calls almost always fail, yet SMS and data aren't a problem. Of course, when my SIM is in another phone (Nexus 5 on Telus, Galaxy S5 on Rogers) I was able to do everything without any problems: calls, SMS, and data.
Thoughts as to what this could be? Is this a hardware issue? If it's software, what could it be? My warranty's out and I'm willing to flash anything or pop the phone open (already have to make sure antenna isn't disco'd).
Thanks!
Have you tried the fob1 firmware? It's the latest kk release for the Canadian s3.
Yup, that's the firmware I'm currently on. Downloaded it from SamMobile, flashed via Odin. I'm literally running the stock firmware right now, no root, only TWRP as recovery so I can more easily flash any modems or bootloaders (vs using fastboot).
OK, so further to this issue, I contacted Rogers technical support. Spent about half an hour on the phone with the tech, went through a few things:
1. He reset my voice account, didn't help
2. Had me search in the "Network Operators" list, no networks ever show up
3. Had me use my old phone (Nexus S, network unlocked) to ensure that it's not my account. All tests with the Nexus S went fine.
4. Had me test different network bands. Bingo!
The phone can place and receive calls when I set the network mode to 2G only (or GSM only). 3 out of 3 calls came in, 3 out of 3 calls went out. Then again later we tested incoming and outgoing calls, still on the 2G network.
So technically problem solved, but realistically not really. I am able to get voice, text, and data (solved!), but I'm paying for a LTE data package and should at least be getting 3G mad.
Any idea why my phone would be working on the 2G network and not on the other ones (3G, H+, LTE)?
This is crazy but the baseband and modem are one fob1? I know you said you flashed a stock rom but it may be worth checking.
My niece is using an unlocked bell s3 on Rogers and she has no problem with voice, data, or text when setting the network to wcdma only or wcdma/LTE.
Yes! Both Baseband (modem) and bootloader are the same. I just downloaded Phone Info (Samsung) to check this, and they both report being FOB1.
Now here's something that's irking me quite a bit. I only just discovered this and do not know if it is of consequence to my problem: I have no PDA or CSC version and Latest Firmware is reporting "Not Found" in the Firmware tab of Phone Info. I've attached a screenshot so you can all see what I mean. Is that normal?
Is phone running a custom rom?
That's right, I just restored a NANdroid of CyanideL (5.1.1).
So this also happens on a stock fob1 rom too?
I am almost tempted to say it may be a hardware issue.
That's right. This happens with a custom ROM (e.g. CyanideL, 5.1.1) as well as a stock ROM that's been freshly flashed via Odin (FOB1, 4.4.2). When flashing with Odin, I'm doing a full wipe via TWRP. Wiping /data partition as well.
I'm inclined to believe this is also a hardware issue, but it just seems bass ackwards in that I can get everything (minus LTE) working while on 2G, but I lose voice access if I move up beyond 2G. I could understand if I couldn't get any voice, SMS, or data, but that going down to 2G solves all my problems... it just seems weird!
Can you try the phone on another carrier? This would probably be the final test you could do. Sounds like you have tried everything.
Yup, tried that earlier on, when I tested my SIM card in some friends' phones (one on Rogers, one on Telus), and while doing that also tested their SIM cards in my phone. With their SIM cards in my phone, the same problem happens as when I'm using my own SIM card.
Gah! It's frustrating, but something I can live with for now until I can get a new phone. I just still can't get over the "everything's fine" on 2G, but moving up to 3G or beyond and I completely lose voice. A colleague of mine has the same phone and the same plan, bought only a month or two before I bought mine. He's got no problems at all with LTE and voice. Although he was on the unofficial CM 12.1 nightlies (5.1.1), I don't think that would have any perceivable difference than when I was on CyanideL 15.x (also 5.1.1).
Hey guys, just unwrapped my new N5x and popped in my sim card. Yet for some reason I can't make or receive any calls!
Calls to me go straight to voicemail, and when making an outgoing call it either immediately says call ended or after a while says network unavailable.
The strange thing is that the entire time I'm connected to LTE (full bars) and data works fine (I can use chrome), and I can even send and receive SMS!
It's been like this straight out of the box. I reset the network settings, then factory reset the device, then upgraded to 6.0.1, rinsed and repeated with no luck.
Probably related: I tried setting the phone from LTE preferred to 3G or 2G but it still says connected to LTE. Even did it manually from the *#*#4636#*#* and nothing changed.
I'm using HOT Mobile in Israel and the American version of the phone. All bands are here are supported.
Any thoughts on how to proceed?
Do US specifc models of phones normally work fine in Israel?
I know I had these symptoms when I managed to accidentally swap my UK model to use USA bands. Only potential difference is that I don't think SMS worked for me.
If someone more knowledgeable knows where the "Network settings reset" pulls values from and to, that might help.
Or which partition holds the data that makes a US phone a US version and an EU phone an EU version (assuming it isn't hardware), we could potentially flash stuff.
Yeah they do. I have a friend with a 5x and his phone is working fine. :/
Check your apn settings, re add them again to test.
Maybe your network do not support lte calls, try it on 3g. This was my solution even thought my network supported volte and worked on s6 but not on my 5x.
I see you tried the 3g option, my problem was another app causing the conflict between lte and 3g. Able to source for another spare sim to try?
I deleted the apn settings - no luck. tried 2 different service providers and same results with both
I havnt installed anything yet and wiped the phone to be sure. Could a stock app be causing the conflict? How can I check?
did you try having your friend put his sim in your phone and yours in his to see if it works?
Yep - he's on the same service provider that I am. Didn't work. Also tried a Sim card from a different service provider.
Here is a solution if you still need it http://forum.xda-developers.com/showpost.php?p=64023143&postcount=10
So I rooted my J2 (SM J250F) and one of the apps I installed is a mac address changer. I was using it to get around a 30 minute limit at airport wifi. Well I think it messed up the efs partition because after using that app I cannot connect to mobile, most of the time it will not even get a signal. The IMEI, serial # of device and model name match the sticker under the battery.
I did not backup the efs partition and I have used odin several times to get back to stock, tried kies program which told me to try smart switch, which I then had to use a older version. Smart Switch keeps saying to check serial and model name over and over even though its correct. I am a little unsure how to proceed from here. I just created the pit file and backed it up along with the corrupted (I assume) efs partition.
Anyone know what to try? I'm not worried about breaking it more as its already a expensive calculator. lol I feel like using odin and start ticking boxes under options even though I don't quite understand the implications. I read that samsung kies/smart switch -restore/initialize can put back factory settings that are unique to your phone, however that option is not working.
Edit: update, I think I may have been in a area with no service. I was at Chicago O'hare and connected to att when I had service, then in Green Bay where I had no service (tried sim cards for both att and tmobile) Now I am on the border with Canada and the phone has service on Rogers. with the att sim card. I guess the J2 is a poor international phone and I need to research the carriers bands a little more.
Hi folks,
I recently bought an Active Watch 2 and already have a Vodafone UK mobile account to which I added the One Number service.
I've discovered that on my watch while on 4G, I cannot make or receive phone calls.
There is definitely a data connection there, as I can send a text message or use the Internet browser app to view a website.
What happens is I dial a number, I get 2 beeps and then a Call Ended message. I've spent over 10 hours on the phone/chat to Vodafone trying to get this resolved to no avail. I've done a number of resets, SIM swaps etc.
This morning I noticed on the watch under Settings in the Phone app, that there is an option for "Preferred Number for Calls" which is greyed out and set to 'Watch'. I'm sure at one point when I first got the watch I was able to select Phone or Watch. Could this have something to do with it? Is the VF network blocking the call because the watch is trying to phone from the One Number secondary number instead of my contract phone number ?
Any help appreciated!
Hey there.
I have the exact same problem myself, my carrier is o2 and have an Active2 LTE.
Set everything up through the esim QR Code. I am the £5 data per month, and yet am unable to make or receive phone calls through LTE / Wi-Fi. No issues though with data and messaging.
It occasionally worked when I first set it up a couple of months ago, but since the latest Tizen update to 5.0 something, there is no option under 'remote connection' in the Galaxy Wearable app to make/receive calls. When testing my original Galaxy Watch out, the call option is there and it is on Tizen 4.0 and I am able to make WiFi calls.
At first I thought the issue was with o2 but am now thinking it is related to Samsung services. Via Bluetooth the Active2 works fine with call functionality but through WiFi/lte, nothing. The odd issue as well, is that, when testing through LTE on the watch it remotely connects very briefly to the phone when attempting the call but then the phone automatically disconnects from remote dialling.
I would say that it is definitely software related, I also have tried all troubleshooting issues and more with no luck.
Hey there. Have you managed to get a fix for this?
I have been in contact with both o2 and Samaunf on this very issue and Samsung are saying to send it in for repairs. I am very dubious though that it is a hardware issue, rather software related.
Hi I have now got both a galaxy watch and a galaxy watch3 here in the UK to now work stand alone on a pay as you go ESIM and wondered if some of my findings may help.....
First the Galaxy Watch i bought second hand on an auction site
it had been on EE in the UK and when i first loaded an esim on it I could not make calls or connect to the network...
I looked under settings connections mobile networks only to find that there was no option to select 3g / 3g4g mode ....
Hence the unit was setup only to connect via 4g data ....by default ....and so would only send Voice calls over LTE ...and hence when i changed the ESIM from EE yo Vodafone I could not make calls or SMS ...and only had emergency calls over vodafone if i was in a 4g service area with no ability to search for or connect to 3g
So I downloaded OXX versions of the firmware instead of OXA for the UK ...and i got the earliest version i could find.
Then loaded it onto the watch ... then I checked the CSC and EE where using a non BTU CSC code so first...
I changed the CSC to BTU so I could support non EE ESIMs
Next I Uploaded an ESIM from Vodafone via Galaxy Wear on a samsung phone over a bluetooth link after first activating
the esim test feature of wear app to enable QT code scanning to load the ESIM.
The OXX firmware activated the 3g 3g-4g section option under settings connections mobile networks so i could enable 4g/3g auto selection .....then the watch could find and connect to 3g or 4g networks and make voice calls and send / recieve sms.
then I put the watch into firmware download mode to install OXA firmware ...and it was an the oldest version i could find
the watch rebooted and so i now had OXA firmware with the 3g-3g/4g toggle still present under settings.
checked it was on 3g-4g auto selection.
then I enabled Dexv mode and made sure the CSC was still on BTU for generic UK ....it wasnt it had changed so I reset it to BTU
then I upgraded the firmware to the latest version via wear app ...
So end up with a generic BTU UK CSC with the latest Firmware BUT with the 3g/4g selection option under mobile networks.
with another service providers ESIM installed 3g/4g to auto select and it all works fine.
hence myadvice is if you dont have 3g/4g then the watch may be locked to 4g ONLY and VOLTE as its only mode with the CDC set to something generic EE for example...
Hope this is of assistance as many conplain that the watch wont work stand alone for voice calls or sms properly
my days of time and many esim tests until i got 3g support and 3g-4g auto load lead mr to think that the watch is often
locked to 4g data and VOLTE only ....
I now have done this on watch and watch 3 models with full sucess stand alone pay as you go esims ....with the watch fully stand alone...working like a normal cell phone ....with esim service with a different provider to the sim in my samsung phone
comment please .... hope that helps
Hi. My problem is different from this. I can make and receive calls from My Active2 LTE and I can also send text messages. However, I cannot receive text messages. Basically I bought this watch to rely on this for calls and messages and this got totally disappointed me.
Any advise on how we can receive text messages?
I have had this problem too. The issue is in phone settings. Go to ADVANCED FEATURES and turn on ALLOW CALLS ON OTHER DEVICES also turn on mobile data in this setting.
