I concur on going to T-Mobile and getting a new sim card for free.
In the least it sounds like your card works partially, so why not get a new fully functional one...

I had the EXACT same thing happen to me.
Call tmobile and have them send you a replacement phone--it was the only thing that worked.
(mine happened within a day of sim unlocking my phone...no clue if there was a connection).
tmobile WILL replace your phone, even if you bought it on craigslist. When the guy tells you 'no', tell them you would like to speak with someone about canceling your account.
Tell that person your story--how you are a good customer, how this phone was working, doesn't work now, etc...
Tell them that AT&T (true) will replace a phone you bought on craigslist, as long as it was an ATT phone and still under warranty.
This worked for me.
Worst case, you can send it back to samsung (but they won't send you a replacement...you have to send it in)
Good luck!

[Q] Unlocked TMobile Samsung Note II no data on ATT Wireless

Hello All,
I am having an issue where I am unable to get any data on my Unlocked TMobile Samsung Note II. I am currently using a ATT One X+ and get full bars of LTE service in my area, while I understand I will not be able to get LTE service on the device, I cannot get any data. The default APN on the phone was Cingular 410, I've also attempted to create a new APN mirroring the exact settings on my HTC One X+. I've reflashed the stock OS and bootloader and issue persists.
I've done some searching and found one similar issue, I am currently using a NANO LTE slim from my ATT iPhone 5 with a nano to micro converter. The post I found said the user had some issue doing this as well and went to ATT for a LTE Micro SIM and his issue was solved. I'm not sure how this would make a difference since the Nano to Micro works just fine in my ATT One X+.
I was under the impression from what I read online I would just need to pop in my ATT LTE sim into the Unlocked TMobile Note II and be on my way with any data lower than LTE. I have also verified I am successfully able to make calls with the ATT sim inserted into the Unlocked TMobile Note II
Any insight would be beneficial? Thanks!

Did you change the apn?

Turns out I thing I got scammed, thanks craigslist. I think the modem is blown out on this phone, My phone will not even register a SIM is inserted in it anymore, even when using a TMobile SIM.
Is there anything I can do, go to TMobile or reach out to Samsung for support?

Would you mind sharing what happened and what's wrong with the modem? When you bought the phone, didn't you put your sim in and test it?

You need to do some work, but im pretty sure everything can be back up and running, another user was able to restore the blown efs/nv/modem on a messed up GNII, once he had that working, even injected a Behold imei onto the phone and get full service...
Search the forum for the thread, ill try to find it and post it here for ya
Edit: here is what the guy did... the links he refers you to should show you all the steps you need to do... hopefully this helps....
"Here is what i had... i lost my note and got a replacement.. then i found my note in my girls car.. no service i insert my sim no service my imei was blacklisted. so i googled ways to change my imei. no dice the terminal emulator way didnt work. i said i got a paper weight and i can **** with it so i did.. got in the service mode *#197328640# and toyed with everything in there.. lost all the network setting and signal and in the
umts /debugmode /common/ rebuild nv it said it will delete my efs part. so i did haha lost my imei bootloader serial number and everything that makes my note a phone. a few days later i was at it again but this time i was going to fix it hoorah! so read and read bout efs part and googled some more and more.. and found this..
http://forum.xda-developers.com/showthread.php?t=1801997
what i did was backed up my new notes efs/ nv files and used them in my other note.. now i have 2 notes with same serial number and imei i gave one to my wife and both are working like new.. but having 2 phones on same family plan with same ime/sderial numberi just wont cut it. so i decided to change the imei and foud this....
http://forum.xda-developers.com/showthread.php?t=1804123

Can't get straight talk to work on my unlocked device

Friday I bought an unlocked Att galaxy note 2 from craigslist. I took it hope and ported my att straight talk number from the normal sd card to the Att mini sd. I waited until my number ported, put my card into the phone. I turned on my phone and had 4g serivce all day. Next morning I had nothing. I would flux between 4g, edge and nothing. As of today, i don't get 4g at all. I'm lucky to hit 1 bar of edge. Now when I don't have serive, I get nearly full bars of emergency calling. I tried the tmobile sim from straight talk and my fiancee's tmobile pay as you go card. Same deal. I tried every apn setting I could dig up. I also checked to see that the IMEI wasn't blocked. Any help would be nice. this is would be one heck of an expensive 5" tablet considering I have a nexus 7.

Custom ROM, unlocked? You ordered the micro SIM from straight talk? Have you tried an att SIM card? you said you got the same thing from your GF's t-mobile SIM, could it be that straight talk registered your SIM with only t-mobile towers?

They person said they unlocked throug att. It was unrooted w/ stock rom. Ordered, no but my micro sd was from a kit I bought when I started straight talk. It was the att straight talk micro sim. It didn't come with a micro tmobile sim so I had my normal sim cut. I tried both of those and my gf's tmobile sim. All three had the same results. I'd get service for maybe an hour then it mostly stay in emergency. I unlocked the aws bands and I got service for a bit but then back to not able to find. Under network operators it can usually only find ATT. I rooted and flashed a stock tmobile rom (read it might help) and nothing. I did notice that sometimes when I restart the phone it will say Att, like its trying to connect. I'm starting to think that the people I got it from maybe didn't unlock the phone. It seems to want to connect only to att but I'm not getting any kind of message saying my sim is invalid or anything. I checked the IMEI number and it says it's not blacklisted.

Ok if your placing a different carrier SIM in your phone, and your not getting any kind of SIM pop up! Then the phone should b unlocked!! As far as the signal not sticking might just ba modem thing. So if you haven't tried changing the radio/modem then that would b your next option. One other thing is to check your APN setting also! That may also help you out. I made a list if you need them!

Nope, never got any kind of sim pop up other than the one at start up that says prepairing.
The modem/radio thing, is that when you hit *#7284# and change it to the second one from the bottom? Or is it more of something I need to download and flash? Like I said, I did the aws enable thing.
More detail on my signal change is, I'll be at 4g after a factory reset. I'll get 4g with near full bars. After a short time it will either drop to edge with maybe 1-2 bars or just get emergency signal. Mostly it sits on emergency. I've only seen it try to connect to att with a tmobile sim a few times last night while working on it. I was questioning the antenna being broken but I usually get near full bars of emerency.

#1 you do have a TMO GN2 right?
#2 are you still on stock Rom?
#3 the*#7284 menu, don't know who told you to go in there but that's not how you change your modem at ALL!!
You flash your new modem in recovery as you do any other zip file!
#4 did you try changing your APN setting, or setting up a new 1??
I'm my buddies TMO GN2. He has a TMO modem, with att apn setting.
So if it's an actual TMO GN2 then add I said b4, your ok flashing a TMO modem/radio. Whatever you want to call it!!!
Do me a favor take a screen shot of your about phone. And I'll b able to c what you have!

I'll get screen shots when I get home from work. I don't the phone with me.
1. I have an Att unlocked GN2
2. I'm on stock rom, but I'm rooted with CWM recovery.
3. I unlocked the aws settings to open up the tmobile abilites this phone as built in (according to the instuctions and such from galaxynote2root.com). That answer is also why i dialed the funky *# number.
4. I did not try the settings from your link. My GF has the phone during the day since she doesnt need to have solid service. Thats why I'm using her tmobile account. eventually I'll be popping in my straight talk sim if I can get this to be something more than an expensive 5" tablet.

Here are the some screen shots from my status menu. I hope I blocked all the stuff that I needed too.

I guess I can check again. I've check a couple times. Its just wierd that when I flash a rom or factory reset or sometimes it only takes a restart but I'll get like 5-13 m/bs downloads on 4g for anywhere from 15 minutes to an hour. Then It will just pass between edge and emergency. I wish I had a true att card to test it on to see if it works for them. I'm going to try my new att straight talk sim tonight and if that doesn't, I think I'm done messing with it. Just going to sell it as is and pick up a nexus 4 or GSIII.

Hopefully it works and it doesn't end up blocked cause thats some messed up people that do that I bought my first note 2 on Craigslist and it had a screen protector on it after I got home took it off some many scratches on it . Guy said it was brand new . He also changed his number when i tried calling him . My brother also got scammed with a blocked imei I dont understand how people do that
Sent from my SAMSUNG-SGH-I317 using xda premium

Yeah. This guy has remained n contact and stuff. It was sold as "like new" but there were a few scratches on it. Good thing is zagg covered them up. Bad thing is, I spent $45 on a nice case and zagg for a phone that I can't seem to use. I did find someone at my work willing to pop their att sim in tomorrow and see how that goes. This is the nicest phone I've used. I like pretty much everything about it. It's a big upgrade from my google nexus.

I understand what you mean! But there are those type of people out there always trying to get over. Or make a quick buck$!! Which is SAD. Guess that's why I always buy my phones from the AT&T Store. Never any problems!
Side note: Always over inspect something your buying from someone online!!! Especially electronics...

Ok that's good your going to check it with a actual AT&T SIM. Cause then you'll know if it's the phone or the other SIM card you have?? If it still acts up with the AT&T SIM. Then it's the phone!!:banghead:
I've also read that the SIM tray could b messed up, possibly?
Some owners had reported there's being damaged!!
QUESTION?? I went back thru the post and noticed you said you had, a micro sim kit? Is it something to make a micro out of a regular SIM? If that's the case then I hope that's not causing your problems. Or even started them!
Well let me know what happens when you try out the AT&T SIM card!
One other thing you can try is to put the stock firmware back on the phone and see if that restores everything back to normal for you. Just a taught... because maybe,, that guy had flashed a Rom on there. But just put back what he taught was a stock Rom. Like one of the stock releases from here..

I bought a straightalk kit from walmart. It comes with a 1 month card for service and 3 sims. 1 normal att st sim, 1 micro att sim and 1 normal tmobile st sim. The problem is once you activate an att card and then switch to another one, that card is dead. Att is trying to get out of st.
I did root at one point but then return it to stock after. I recently rooted and flashed again to try out a tmobile rom.
This is a lesson for me. I didn't know about IMEI on a phone so I didn't know it was easy to screw someone. I paid 350 for the phone. I guess that was too good to be true. As much as I like this phone, I think I should have just bought the nexus 4.

Ok so you think the imie# blocked, messed up some how?? Just as Brazil said is the unblocked or unblocked on AT&T??
And yes I know AT&T is trying to get away from ST! But shouldn't be problem for you to use ST from TMO or AT&T. Which they both share.. FYI

Reason I thought it was blocked was because my brother got scammed with a blocked imei and he would put the sim in it will work then signal will just drop then he will restart it and it work then always keep droping.

That is kind of what is happening to me. I have done several IMEI checkers and they all come back valid. I just checked again and it's still marked as valid. I'm porting my st number from regular sim to micro now. Its been about 2 hours so hopefully it activates soon. I'm hoping it works.

[Q] Just got an S3 model I747M but wont make calls

Im new to this phone
So the original carrier is Claro PR. I have succesfully unlocked the phone cause im using AT&T SIM on it and it has signal and all but it wont make/recieve calls, nor text and wont go on the internet.
Anyone have had this happen before on unlocked phone? I was thinking on rootinh it and throwing a AT&T rom to see if it fixes it but im asking first before trying anything that can brick it

Did you unlock it using the free method or by a code?
For data, did you check the APN settings? Under network preferences, did you select auto? Are you sure the SIM is registered on the network?

nope contract its a contract one

I'm at a loss as to why it doesn't work even though it gets a signal. Maybe something is screwed up in the service menu settings.

Well be happy sounds like the Sim which is really cheep if not free to get

[Q] Is this thing factory unlocked?!

This might seem like an odd question but I was poking around my note 4 today and i'm noticing something interesting within the settings. If you go into Settings> More Networks> Mobile Networks you can see a small list if mobile network options. If you select Network Mode, you can see it has GSM/UMTS as an option to select. Going back you can also see within that small list of network options a grayed out setting "Network Operators." This leads me to question, is this phone capable of being used on both GSM and CDMA? If not with factory Sprint settings, possibly something the hardware is able to do unlocked? I just find it interesting that the device offers different network options than the standard CDMA/LTE that I am used to only seeing on and once more there is no carrier branding on the device at all outside of the initial splash screen upon start-up.
What do you guys think?

Before my sprint note 4 was activated, in the apn settings,i was able to edit it as there was nothing in there. Once I had activated the phone it showed the sprint one and had became grayed out being uneditable.

Interesting, thanks for the share. During that brief moment you had in the APN Settings, did it display list of carriers or was it like an actual edit option for you to place input? Im curious to find out if this thing can actually run GSM network sims.

ask sprint for a sim unlock...and check

It was the actual option to edit it and there were no carriers listed.

You guys may be on to something!!!

This might seem like an odd question but I was poking around my note 4 today and i'm noticing something interesting within the settings. If you go into Settings> More Networks> Mobile Networks you can see a small list if mobile network options. If you select Network Mode, you can see it has GSM/UMTS as an option to select. Going back you can also see within that small list of network options a grayed out setting "Network Operators." This leads me to question, is this phone capable of being used on both GSM and CDMA? If not with factory Sprint settings, possibly something the hardware is able to do unlocked? I just find it interesting that the device offers different network options than the standard CDMA/LTE that I am used to only seeing on and once more there is no carrier branding on the device at all outside of the initial splash screen upon start-up.
What do you guys think?

Before my sprint note 4 was activated, in the apn settings,i was able to edit it as there was nothing in there. Once I had activated the phone it showed the sprint one and had became grayed out being uneditable.

So me being the sly little devil that i am, decided to check my apn's on my phone which turns out, THAT THEY ARE EDITABLE!!!!. So i can know assume that the phone may come factory unlocked and that we should add another carriers apns and sim card to try it out. I believe this is the reason why the phones dont have the carrier branding on them, because they are proprietary to samsung before activation, and then that carrier adds the signed/encrypted packages to the phone. So, with that said.... I NEVER ACTIVATED MY NOTE 4. i SWITCHED BACK TO MY NOTE 3 AFTER I PURCHASED THE PHONE. ( sorry for the caps, pure excitement) Then I skipped the activation and blocked the phones internet access, so here i sit with an non activated sprint note 4. If anyone wants me to test anything let me know!

Here are the pics.

I got this ...

yeah... but I do believe if you get an unactivated one and run the setup with another sim you could get it to work!

I believe this as well

Any idea what I beed to do to save the apn. They wont atick. Should I acquire root?

i stuffed a tmobile sim in and got the invalid sim msg, if its anything like the s4 etc we will need to sim unlock it and then domestically unlock it.
you can always ##786# and enter your MSL to reset the device if you think sprints programming is the thing messing it up, however it really does wipe the device.

its a no go

I can see att and tmobile network, but i did some browsing in the build.prop file and discovered that there is a setting that says uses sprint sim card only. So It turns out that sprint used the same lock method as the note 3 on this. So now im trying some other things, going to look into a jtag and solder directly to the chip to read files and write them, so i can find out whats really going on with this unlock behind the scenes

sim locked
I'm stuck with my sprint galaxy note 4 unactivavted .
Did you guys ever get yours unlocked
if you are still with sprint .
One guy told me that i would have to get Sprint to do a international ulock and that will unlock the sim but the phone has to be active on sprint's network for them to do it
If their is a way to unlock my phone without going to sprint please tell me thanx and good luck

same here have this sprint n910p trying to unlock or use it with gsm slot any carrier how to go about it

I just hate sprint so bad, I have the nexus 6 witch I know I can take to a GSM carrier but we are wondering if my wife's Note 4 can do the same once we pay them off.

Currently the note is not sim unlocked in the US they are unlocked for outside the US. But with in time I'm sure some great xda member will find a way like they did on the note2

ask sprint to do a " international sim unlock" now because you are going overseas for vacation . they will not do it if you dont just to go to another carrier but thats what I found out after they do that then the phone can be used with another carrier. that is what I didn't do and now they said I would have to get their service two year contract and keep it for 3 months and then they will unlock sim pay early termination fee goodluck

Galaxy Tools has a SIM unlock button in it. I pressed it and it says Im unlocked now but not sure. So as far as sprint unlocking it for you I think its possible you can do it yourself for international.
