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] lost phone, can carrier help?

i was wandering if i lost my s3, and the person that uses his own sim card. Can wind or any service provider see who put their sim card in and activated the s3?

Don't know, but, if the person has not deleted your account from the phone you could send an email to yourself and either offer a reward for the return and tell him you are about to lock it and make it unusable.
You can also play store on your computer and install Wheres My Droid and hope he puts your sim back in for a few minutes!
Then on someone other mobile phone send your phone a txt of
WMD GPS
it will send back the location
See the website for other comands you can send to it.
Can't hurt to try and hope he puts the sim back in.
Definitely install it on your phone if you get it back, or your next phone.
It can send you the new number if they change the sim!
Good luck! Hope it works out!

Pretty sure the person has restore the phone and put in his own sim. Can carrier track the phone and who is using it now?
Sent from my SGH-T999 using xda premium

I'm 99.9% sure the answer us no.
They will mark it as stolen in the system.
Your only hope is stated above.
Sent from my SGH-T999 using xda premium

Yes they can but they won't. Have you tried android lost app ? It allows you to find your phone even if you never installed the app before it allows you install the app using your gmail account to your phone and send info to your phone using the web or a different phone.
Anyways go and take a look on androidlost.com for more info.
Good luck

I lost it for 4 week now. They probably already restore it along time ago and start to use it with their own sim card. Can the android lost app still work?
Sent from my SGH-T999 using xda premium

No, it will not work if your account is no longer on the phone.
I would suggest you call your carrier and ask if they can locate the phone by IMEI + GPS/etc - that's about your only hope (and I don't know if they'd do it, or if they'd block the IMEI, or if they'll only do that if you have insurance, et cetera). Also, 4 weeks is getting a bit late, unfortunately.

No carriers can help you. If you have insurance then claim it. They will block it since it's stolen.
It happened to me but I didnt get stolen but more of a scam.

Yeah I'm pretty sure they can track it but they just can't give you an address then if something bad happens you sue them lol. Crimes may happen over a phone phone companies won't get involved in that. Also really they don't mind that you have to get another phone meaning most likely paying them.

Agree. When my wife lost her phone I asked carrier about this, and their answer was a straight "Sorry, we can't do that". I wish there's an app out there that tied the IMEI to a GPS tracker that's made available for consumer use, though that in itself can probably cause a different issue altogether.

There was a recent story that came out where this guy and his friend from his computer tracked the guy who stole his iphone 5. Started beating him up lol, then the guy who stole it got arrested I believe. Now that's justice!

[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?

Your sim card does not allow a connection to this network

Hi guys, I am sorry if it was already posted here, I could not find similar topics or posts. I have a problem with the network. When I try to call someone it says 'not registered on network'
I have been using galaxy s3 tmobile since last year november. I bought it from a police officer, he gave me unlock codes from tmobile. I used the phone on tmobile for 6-7 months and than I switched to staright talk unlimited and have been using it till yesterday. Yesterday suddenly my phone/ data/ sms.... stopped working. I was using cm10.1.3 than I thought, it is related to kernel/radio or modem and flashed back to stock rom.
But I still have the same problem.
The signal bar is full. I went to apn setting and played with it little, but no results. I tried to connect to the network, it says ' sim card does not allow a connection to this network'. I chatted with tmobile agent: she said, it must work on any network other than tmobile. I put my sim card on iphone, it works, but when I insert any simcard on my phone, it gives same issue. I checked my imei on tmobiles network, the result is: imei blocked. Could anyone help me with it please. ???? :banghead:

If the IMEI is blocked then the seller has reported the phone to be stolen. There's not much that can be done in that case to the phone. You can talk to the Seller if you want.

Doesn't sound like a police officer to me. Probably lied to you to make the sale. Either he reported it lost/stolen like Perseus said, or he never fully paid it off and stopped making payments. Either way, the device is now almost certainly considered to be stolen property. You can unlock it and sell overseas, but otherwise you are pretty much screwed I am sorry to say.
You need to call T-Mobile to find out why it's been blacklisted. If it's been reported stolen, or was never fully paid for try to contact the seller and ask about it. If you can't get in touch with him you may want to consider filing a police report.
Only other possibility, but highly unlikely, is if some a$$ cloned their device using your imei (either randomly entered or obtained some other way). In this very unlikely scenario it wouldn't be the sellers fault, unless he gave the IMEI to someone to use or used it himself.
It's much more likely the seller did this to you since this, unfortunately, happens all the time.
Like stated previously, there isn't much you can do if you can't resolve things with the seller.
Sorry to hear about your misfortune.. good luck though.

Thank you for the replies, I have called tmobile, they say it's not fully paid off or the customer has stopped the services at all, at the time of purchase I was 100% sure he was police officer, he showed his badge and all the stuff in the car.
How can I unlock it? I might want to sell overseas.
Anyway, I was thinking about move to n5, but it is too early, coz n5 is not out yet
Sent from my SGH-T999 using xda app-developers app

In the general section is a SIM Unlock thread. Should be on the first page or two.
If he is actually a cop, I'd call him up and ask about it. If he only recently cut his service, it may have been unintentional that you got screwed as a result. Maybe he had forgot all about it. Considering how long it's been, he probably had it close to paid off, so maybe he'd be willing to pay off the balance to T-Mobile to have it unblocked. Or it might be worth it to you, depending on the amount owed, to pay it yourself if he can't or won't.
Granted, it would suck to have to, but if he only owes like $50, might be worth considering.

If its not paid for then t-mo will release it after you pay up. Nexus 5 is ways away. You will have to go without a phone.
Unlock, ask T-mo or use online services on ebay

Well it is pre unlocked, or should I unlock again?

No Need. If you know its unlocked then go ahead and sell Overseas.

Thank you very much who helped me with this issue, and of course the seller cut his services and even his number is not available anymore, no replies from email, but I am happy that nexus 5 is play store now, yeey

[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.

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 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

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.
