I got an UNACTIVATED SIM card from AT&T and inserted it into my GS3 (supposedly unlocked)
No prompts for anything came up after booting. Is the phone really unlocked?
Is that a valid test to see if the unlock took, or does the Sim have to be Activated?
Wondering......
Thanks for any light that can be shed on this!
If you haven't got anything asking about some code or something then I think you're good. But to make sure activate your card and check if you're getting signal and data. But I think your phone is unlocked.
Give me few minutes I will checked that on my locked phone also with att sim.
Update: Sorry, can't check that. I forgot that sgs3 has micro sim and my att card is regular sim. Maybe someone else will be able to help more.

I have a new T989 I bought without a contract. I have a Simple Mobile sim card. I have rooted and installed Juggernaut Rom. Before I rooted and now no changes in the fact when I install any sim I get no message of invalid or a place to enter unlock code.I know SM is suppose to work without unlock. But I havent been able to get SM to work at all. Do i need to flash another rom, because it seems that Im locked into Tmobile so far. Any help much appreciated!

Which .apn are you using? are calls working with the exception of data and mms?
Sent from my SGH-T989 using XDA App
I have not changed the .APN. Nothing is working , there is a circle with a line through it in top status bar. Just get " mobile network not available" Im lost at how others have used Simple Mobile sims with nothing extra but to configure the mms/internet.
simple mobile is tmobile, you can use a tmo phone without unlocking with a simple mobile sim, i still have my simple mobile sim from when i used it on my vibrant, and i was able to make a call from my sgs2 without unlocking, so i might be wrong but you should try with an at&t sim, the apn settings for simple are on their site also.
Weird, I'm experiencing the same issue.
I believe the Simple Mobile SIM card is fine, because it works in /other/ (non-smart) phones such as my T-Mobile branded Motorola V195 and Nokia 6030 - I can place and receive calls and text messages.
But the Samsung Galaxy S II T989 is always stuck on "Searching" on the lock screen, and Settings: Wireless and network: Mobile networks: Network operators: Search now: only turns up "T-Mobile" and "AT&T" under Available Networks, both of which say "Your SIM card does not allow a connection to this network" when I tap on them.
Oh yes, and I did program the Access Point Names (APNs) as per Simple Mobile's instructions, twice.
Both with the stock ROM, and with Juggernaut-v4.1 (as it so happens). Baseband version T989UVKL1.
I'll try and find someone with a working T-Mobile SIM card, test that in the phone tomorrow, and report back.
Sim is prolly bad I had same issue when I first put my sim in try another simple sim, maybe sticking it in non smart phones Burns something cus that's exactly how it went down for me:/ when i was using an older phone as a temp, then bought the sg2 and didn't work try using ur sim on another smart phone if it doesn't read it it's toast like mine was

I tested a coworker's T-Mobile SIM card in the phone and had exactly the same problems (no network/unable to find network - just AT&T and T-Mobile), whereas my coworker was able to use my SIMPLE Mobile SIM card in their phone successfully.
I flashed my baseband from to T989UVKID *, and the behavior is the same - still saying that it's not registered, and still only shows AT&T and T-Mobile when I search for networks. Co-worker's SIM card still doesn't allow me to connect to T-Mobile, either.
I'm starting to think the IMEI for this phone might have been reported stolen, and maybe it's being blocked externally (I did buy it from a pawn shop eBay seller - albeit one with good feedback). Hopefully T-Mobile can tell me if I call them up.
*-Well, I loaded the zipfile from topic "1426001 - [RADIOS] CWM Flashable Modems" onto my sdcard and applied update from zip, and Settings: About phone says "Baseband version T989UVKID" now.

probably blacklisted , sounds like this phone is blacklisted a lot people buying and selling before its even payed off , or getting a replacement and then selling

Ya sounds like that. You know what my brother had a vibrant brand new from someone on cragslist and then several months later his gave same problem. He was on Simple Mobile. He called t Mobile and believe it or not said they don't black list phones and say it is not possible for them to do so. It was different reps too that said the same thing. I don't know. Maybe true?

IMEI blacklisted
I just borrowed the SIM card from a coworker's AT&T phone. I had to unlock my Galaxy, but I'd purchased an unlock code a few days ago before I realized that the problem wasn't a SIM lock.
Sure enough, the phone works fine on AT&T's network. 2187 kbps down, 436 kbps up, 105ms ping (in my area).
It's definitely the carrier blocking my phone. Now to see if I can return it. Hey, it will work on the AT&T network now, or maybe the seller can catch the person that sold them the phone.
P.S. Judging by the threads on support.t-mobile.com, Support L1 doesn't have access to or know about the IMEI blocks, but L2 does. Case in point:
support.t-mobile.com/thread/15348
Incidentally, I don't feel that it's T-Mobile's fault that I got a blacklisted phone, although I would like it if they *published* their IMEI blacklists. In Australia, you can punch in an IMEI code and see if it's blacklisted.

Hi all, so my friend got this phone from amazon. The seller said it only works with Vodafone sim so he got one. The sim works fine but the phone wont bloody use it... Calls end before starting and when I try to access calls settings it says there is something wrong with your simcard. The sim card was tested with other phones and works just fine. Any suggestions of how to fix? Currently running android 2.3.2 with 2.6.32.9-perf kernel. Vodafone guy didn't know what was wrong with the phone since nothing was wrong on servers...
Any help is welcome thanks

I thought R800i model is unlocked. Is the phone carrier branded, maybe it needs to be sim unlocked. If it is unlocked, can you try a sim from another carrier.

Well, sent the phone back to the seller. It didnt have any carrier labels on the phone, but for strange reasons wouldnt run the damn sim card thanks anyway (didnt have anyone with different carrier around xD)
I'm really not sure this is the correct place to put this question (Mods, please move it if needed) .... as it sort of needs to be where both the UK SG-SIII users as well as T-Mobile SG-SIII users will both see it.
I contacted T-Mobile C'S and got them to email me an Unlock Code so that I could use my phone while in UK visiting my Mum for 2weeks, but when the email came the very first part of the instructions says "you must perform this unlock function with a NON T-Mobile SIM card installed"
Hmmm well since I am still in Florida, I can't do anything ahead of time but I wanted to try and research / find out what my options were when I get over there (flying into Manchester) ahead of time so that I know what I am going to do when I land.
Anyone out there with experience at international travel, multiple SIMs, pay-as-you-go plans etc?
Any help would be much appreciated. Thanks
It's easy to get it unlocked ... just use one of your friends ATT sim cards from their iPhone because s3 requires micro sim. Pop it in turn it on, it will ask for the code, put it in and your good to go. Then just put your sim card back in and your phone is unlocked for any gsm. When you get over seas find a service that has sim cards pop the sim in and your ready to go.

Hi,
I tried to cut down my old sim card to micro sim to try and fit the note 2; however, when i try and use it, the network says unknown and out of service. It is however getting my phone number and voicemail number. Before I cut it down, the sim card was working on my old phone. If it matters, I see that my imei is still there and it says it is clean on checkesn. I won't have another sim card or device to test on anytime soon. Does the situation make sense? Thank you.
Is touted phone carrier unlocked? Of its not, you'll want to do that soon

The simple slightest cut of gold can ruin service.

The phone's IMEI might be marked as lost or stolen. Check here:

OK, so this weekend I decided to try my AT&T SIM Card with my Note 4 from Sprint. I thought it would ask me for a SIM unlock code or something but it recognized the card and showed "3G". However, I got the card icon which said "Invalid SIM Card".
Any idea why I did not get the prompt to input unlock code? Thanks!

The sim inside the sprint note 4 is only to access the LTE network. So since you took the sprint sim out, you would be only receiving 3g. That is why you are receiving the invalid sim card error, because its not using it.

So I am getting that error because the SIM card is not using LTE? I don't get it. If the phone is unlocked, shouldn't it ask for an unlock code?

There's been plenty of discussion in this forum about bringing SM-N910P to other networks. I'm no expert, haven't done it myself but what I read repeatedly posted is that radios in this version did not allow LTE on domestic carriers when unlocked. Seems a common issue with phones made for CDMA carriers; taking them to another carrier may not meet your expectations. If the limitations are acceptable, maybe you consider going ahead and weigh your options.
Again, there's plenty of threads in this forum discussing this but here's one that I found that may help. To me, it's been rare for @idone to post these days but he posted here.

Thanks for the reply. Yeah I am aware that the Sprint Note 4 would give me 3G or H+ but not LTE which is fine by me. I was wondering why the phone did not ask me for the Unlock code to begin with when I threw a GSM card in there.

Did you find your answer? Or still asking?
It's likely Sprint will give you a MSL number but not unlock the phone to use on domestic carriers. I think you still need to unlock it for that purpose. But the developer I referred you to can do this with or without the MSL. His tools are capable; his service is a full unlock for domestic. I don't think you need the unlock for carriers outside the U.S. the way the phone is currently. Sprint may clear a phone for domestic carrier use but not unlock it or help you activate it. You'll likely find no carrier to help you unlock it either.
I'm sure there are ways to do it yourself but it's gotten more complex with Lollipop and Marshmallow. I'm just not sure how it's done because I haven't fully done it. Only walked through it partially back in KitKat but kept Sprint SIM and service. Didn't try another SIM card.

No I'm still looking for an answer. I have messaged idone on their website and sent a PM. I need this unlocked and take it to H2O. Sprint gave me the MSL code to be given to a GSM carrier but I call BS on that. Strange thing is the damn phone recognizes the AT&T SIM card as a 3G card all right but still says "Invalid SIM Card".

No expert here, but dont you need an AT&T SIM card that has your phone unique ID info programmed into it so it registers on AT&Ts network?
I thought the MSL would just unlock an area in the phone where you would change DNS type info to AT&T's towers/network.
