I have a galaxy S3 (SGH-I747) originally on Rogers form Canada. I bought an Un lock code and unlocked it. The phone shows signal, makes calls and SMS, but NO 4G and NO network access. (internet pages don't load when disconnected from WiFi)
Under Mobile Network I cannot connect to ATT's network. Does anybody know what I'm doing wrong? Or is there a ROM i need to install after I ROOT the phone? Do I even need to ROOT it? (Sorry in advance, i come from the world of Jailbreaking, but have rooted Droids in the past)
Thx!
I'm not an expert, but you probably need to check your APN settings, and change them to AT&Ts if they aren't already. You can check this in Settings -> More Settings (in Wireless and networks section) -> Mobile Networks -> Access Point Names
I don't know what the AT&T settings should be, but you can probably find it easily enough. Also, you might want to Shut down the phone, remove the SIM, reboot without a sim, then shut down and put it in again to make it read the APN settings from the sim
Try flashing the ATT rom and see if that makes it work to start.
Got It!!!
I had to manually add my APN settings. I was over looking the button on the bottom left to configure it.
Thanks for the help!:cyclops:
Does the SGH-I747 (Rogers version form Canada) pick up LTE on AT&T?
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 just bought the phone new off of eBay. Seller stated that the phone is unlocked, although I do still see a "My AT&T" app installed. Anyway, when I first start up the phone (w/vzw SIM), it connects to VZW for about 3 seconds, then says "no service" in the status bar. I have tried editing the apn settings for VZW, but it doesn't help.
Can anybody confirm this phone connecting on Verizon LTE, or have any suggestions for me to try? Any way to confirm that my phone is in fact unlocked?
I'm pretty sure this phone is not compatible with Verizon's network.

Yeah I read through that earlier. The last post states that lte data should be fine.
Hello all. I purchased a edge+ today but whenever I insert a sim, the phone stays on searching. I made sure that I rebooted the device and I also tried re-seating the sim many times. I believe the device is unlocked and the imei/esn is in clean standing with T-Mobile. I tried a MetroPCS sim card and it stayed on searching, same thing happened with a Verizon sim. However when I inserted the T-Mobile sim, it sometimes says no service but ever since I rebooted the device, it stays on "searching" no matter which sim is installed. I find this whole ordeal frustrating since the signal bars show up for the MetroPCS and T-Mobile sim but with Verizon nothing happens. Any help would be greatly appreciated.
Yours is G928T? If yes, it does not support Verizon/Sprint even if it's unlocked.
Did you buy it off of Craigslist/Ebay? It might be blacklisted. checkesnfree.com

Yes, it's the G928T but it's not blacklisted I checked. The simcards I was using on the phone were old ones(no longer in service) I thought they would work. I used a scissor to cut my WORKING sim and placed it in the phone and it took the MetroPCS sim. Everything works fine now except calls and text only work with WiFi Calling on. If I turn off WiFi, I can't text or make calls(not on registered network) but if I turn the WiFi back on, it works fine. Any suggestions?
MetroPCS and T-Mobile are on the same network.
Check/add MetroPCS APN.
Setting -> Mobile Networks -> Access Point Names
Add MetroPCS APN if it's not there.

Yeah I know they are which baffles me as to why it isn't working. I tried adding a custom APN but same thing happens. I get calls/sms on WiFi but if I turn it off I get "No Service"
Just go to metro and get a new Sim. You could have damaged it by cutting it. It should be free. ATT gives me then free all the time. Usually, the phone will just auto update the apn settings when a specific carriers Sim is inserted

I went and it turns out the device is blacklisted. This whole time I was rolling with the imei in the phone, after checking last night, I noticed that the imei on the back of the device differs from the one that's actually on the software. I was able to get in touch with the seller and he's coming back to give me my money back. Guess a mod can mark this thread closed.
Trying to Configure Note10+ 5G (N976V) with Visible but can not add APNs. The option is Greyed out. I was able to do it with my Verizon S10 that is also not officially supported. Crazy thing is that for about 5 min i was able to use the Visible SIM in my Note and Call and Send Txt until I rebooted the Phone. The Phone is paid off and Im using it on Mint Mobile now but it doesnt Show the T-Mo Boot Logo when I switched SIMs like my S10 Did. Has anyone been able to get this to work. I was told by Samsung that I may need to Reflash the Phone.
i have the regular unlocked note10+ working on visible.
N976V on Visible.
I am having the same issue, the APN settings are disabled. If you get this resolved before I can figure out a work around please let me know. Thank you.

Did you work it out? if yes, can you share how?
As soon as someone has resolved this issue, please update this forum page!
I just upgraded my note 8(on Visible) to the note 10 plus 5g. After i put in the Visible sim card into my note 10 phone, the phone was not working with the Visible sim card. I was connected onto the wifi network at work and I went into the settings to update the APN information, but it was greyed out and could not enter that information into the phone. After a few hours of googling to see if I could fixed the greyed out APN area so that I could actually enter in the programming, I said let me check the phone outside with wifi turned off. I went outside and tried to place a call and the call connected. I was then able to get wifi calling turned on since the phone was not allowing me to do so before. I went back into work and tried to place a call on the wifi network and it worked. I also tried sending text messages and mms messages and they all work. I checked the settings under the APN area and the phone automatically populated the Visible Internet setting but it was also greyed out, but it was working and I was so happy. I am so happy now with my new galaxy note 10 5g phone that is up and fully working with the Visible sim card. So I believe that having the phone connect onto the cell tower signal and not the wifi allowed the phone to pull in the APN information that it needed. I also reset via the setting the network connections while I was outside a few times. Hopes that this helps...
Change CSC with SamFw Tool (don't brick your device!!!)
Don't update beyond U4
Unlock bootloader and root.
Modify everything.
Accuse Samsung of being stupid for ever creating such a product with such limitations.
