I just received my unlocked ATT S3, rooted it, cut my sim card down and setup all my apps etc. Problem is that I am having really sporadic network access issues. I am currently in Afghanistan and using AWCC. I had the same sim card in a Skyrocket and didn't have any issues. I have setup the APN (I pay for unlimited edge internet) and randomly get internet access and network access.
Right now I show 3 bars
Info shows
Network: AF AWCC
Signal Strength -89dBm 12 asu
Mobile Network type: Edge:2
Service State: In Service
When I try to check my balance (*123# dial) It says connection problem or invalid MMI code EDIT: sometimes it goes through and I get my balance.
When I try to make a call it just says dialing then goes to Call Ended after about 30 seconds. Same thing happens when I try to call AWCC customer service at 151 (actually I just got through on the 151 number once)
When I go to Settings/More Settings, Network Operators and try manual settings, about half the time I see the awcc network but it always fails to connect. If I leave it is automatic, it will eventually connect. Right now it is showing AWCC in the top menu bar. Other times it says not registered on the network. FYI AWCC doesn't register the sim card to a specific phone. You just buy the sim card without giving any info about your phone.
Every once in awhile it connects as I received emails on the phone over night. As I am typing this I just got edge connectivity and am online.
So, anyone have any suggestions? Maybe I should try flashing another modem?
Thanks
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.
Galaxy Nexus, 4.2.1, bot unlocked from amazon about 6 months ago.
On dec 2nd signal just went off. So no calls nor receiving can be done. While mobile internet is still ok.
Network is giffgaff, running through O2 - UK.
Taking this sim to other phone - works fine.
Support from giffgaff said that everything is perfect on their end.
Putting any sim in this phone, shows same issues - no signal, but there is mobile internet.
Checked status of IMEI, and it says in online services that phone is unblocked.
I have tried on/off airplane mode, restarting, taking battery off for a while, with sim in and out, as well did factory reset - still issue is here.
It is unrooted, just original rom.
Going to settings > mobile networks > network operators > I select any network and it says: "Can't connect to this network at the moment. Try again later.". Same when choose automatically.
It allows to do emergency calls, and in status bar shows: "emergency calls only | giffgaff".
In About Phone section, network is "O2 - UK" as suppose to be, Signal strength "-101 dBm 7 asu", mobile network type "HSPDA:8", service status "Out of service", Roaming "Not roaming".
Please ask any questions if any additional information is needed.
King regards.
I am looking forward to anyone to try assist with this issue, and kin to help.
Contact your operator for change your sim, it happens to me this summer, my Sim card was working well with other phones but with my Gnex everything was disabled. Then I've received my new Sim card and everything is working well

Then other SIMs would work well. But inserting any SIM in this phone - doesn't work for calling. Only mobile internet.

Based on this info, I suspect your radio simply died. You could of course try to reflash the radio firmware yourself, but I would not get my hopes up.

Thanks for info. I thought about that as well.
So would it be the option if I have bought the device from amazon, to use their RMA services - they should replace device.
Is that right?
Thanks for helping out.
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.
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
