Got this phone with the problem already, I installed a custom ROM hoping that would fix it but still doesn't work.
Cannot find network, though it is showing 3 bars?
Can't make calls, can't use data.
WiFi works just fine.
EDIT: Should probablly give some more info:
T-Mobile model
ROM: CleanROM A.C.E.
SIM card works fine in my other phone.
EDIT2: Ok so after more fiddling I got it to pick up a signal from AT&T with the "Find Network" search. I'm thinking this has been locked to AT&T and I just need to flash back to a stock ROM and unlock it, thoughts?
I know I get T-Mobile signal at my house my other phone picks it up just fine and I'm using the same exact SIM in both.

Maybe someone has flashed a wrong modem/rom on the phone so it ruined everything..
You said it's T-Mobile phone.. I guess it's gotta be locked to t-mobile..
I would suggest to post this on T-Mobile Note 2 forum.. They would know a way to solve your problem.. This forum is for international note 2..

*#06 etc to get your imei display on the phone. Check imei matches with imei number underneath the battery. If they match and apeears to be valid you may have a locked or blacklisted phone. Blacklisted means its imei blocked nationally due to fraud such as lost stolen and insurance replacement provided etc.
Good luck

I just unlocked my T989D using the guide on here and everything worked fine. I can even get a different sim working on the phone and use it to call/text but it won't pick up a Data connection.
I just tried a Fido sim and it sees the APN settings and everything but the data connection just does not work.
Can someone shed some light on this for me please?

Data is for internet and apps.....phone calls and texts just use the radio signal. Just to be clear. They're 2 different things. You don't need data for calls and texts. I think you know this, but wanted to be sure.
Do you have the new Telus or T-Mobile radio flashed? Only those 2 work on anything current. So what rom or stock version are you running? With the proper radio and apn settings, it should work.
Tho if its an issue caused by unlocking, then I'm not sure.....never done it myself. Did you Google the issue??

Yah I knew that about data. But I managed to get it to work. All I had to do was click on reset to default under APN settings and it started working.
No idea why that worked because I never entered any settings myself but let the actual phone pick up the stuff from Fido.. oh well now it all works.
so I have the galaxy i747 on att unlocked.
a few weeks ago it bricked itself trying to over the air update. I couldn't fix it so I had it jtagged and it came back. I also paid for an imei repair.
everything was fine, I could make calls and stuff but eventually lost signal.
I sent it back as I ended up bricking it trying to restore to stock rom (it was on philz touchwiz)
he fixed it, said the network problem was due to my simtray.
I replaced the simtray today, I had full signal but when I tried to make calls there was no dial tone and ive lost signal again, this time its running a hyperdrive rom. my simcard is TESCO which shares a network with O2.
it picks up the simcard and stuff im just not getting any signal, when I try to register on the network it says unable to connect.
if anyone could please help me with this I would really appreciate it! alex

I would check your IMEI/baseband. Make sure they're correct.
Also, could check your APNs.

ive tried both those, the weird thing is I get signal and can make a call and receive texts when doing a gps check. something is blocking it but im unsure what.
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).
And WIFI calling?
I had read in a few places this might work. I'm also not able to sync my Galaxy watch to send texts and make calls through my phone's phone number with numbersync. I'm hoping flashing the actual ATT software might fix these problems.
Any thoughts?

well, the worst thing that could happen is that it doesnt work and youd need to flash your other firmware back on the device
I flashed my unlocked cricket S9 to Verizon firmware, because I was on the U1 firmware and needed cricket wifi calling back (and cricket/att firmware downloads are mia) and when I did I got absolutely nothing of Verizon and the phone was recognized as a cricket phone. So in short basically all 0U firmware is the same the same as all 0U1 is the same. It's kind of confusing but basically on 0U your sim/carrier (even if you don't have it in at setup, it remembers the last one you used) determines your 0U for you, so I don't think what you're asking will work.

I have heard from some people that latest(august or so) update on unlocked S10+ that is on ATT network, allows VoLTE to work
