sim unlocking problems

I've tried unlocking my AT&T Galaxy Note 2 using service mode. I downgraded the phones modem to the 4.1.1 version and it worked. I used my metroPCS sim card and the phone did not ask for the code but it said phone not allowed MM#6. When I try to call someone it says emergency calls only. I was wondering if it is because the phone is still under contract or because I'm supposed to use a blank sim card and not one thats already been used. Please help.

[Q] How to verify a working sim slot on LS980 phone?

I get a used LS980 and It havn't activated with Sprint yet. No Unlocked yet. No Sprint sim card handy. Normally, it show NO Sim card on the phone, but when T-mobile or ATT sim card inseted, it still shows "NO SIM Card" I remove the sim card completely, and reboot the phone and insert Sim again. It still show No sim Card?
Don't they support to show invalid Sim Card if insert ATT or Tmobile sim card in a locked Sprint LS980 phone? I have a Sprint Samsung Galaxy locked with Sprint, If sim card inserted, it show invalid. Same with Verizon locked phone show invalid sim if ATT or Tmobile inserted.
Now, it seem likes a defective sim slot on the phone. without activated or a Sprint sim, how to verify it. Please be advice?

yup.. insert any sim beside sprint show No Sim Card message. is it normal for anyone?? or the sim slot defective?
I'm planing to use it on Freedompop. Order a sim from Tint.com could take awhile. While i'm wait for sim arrival, please tell is the sim slot defective or normal?
No one can help? Or test on your LS980 to find if it support to show invalid sim card on your locked LS980?
BTW, This device here still JB 4.2.2 with some of VZ8 firmware. Do I need to unlock for further test?

No SIM card

Hello I have an unlocked SGH-T989D phone but the problem is it will only detect sim cards from Koodo even though it is unlocked, I've tried flashing many different roms and different radios but nothing is working. Currently on stock 4.0.4 /T 989UVLE1, yes the phone is unlocked I checked multiple times. Anyone know how to fix this?

How do you check if a phone is unlocked if any SIM you try from another company is not read by the phone?
I think you need to try the unlocking procedure again, I don't think it was properly unlocked

What method did you use to unlock it?
I did it with this (http://forum.xda-developers.com/showthread.php?t=2024514) and not a single time was I asked to check with the code that you have showed me
This IS for the T989 though, not sure if you can use it for the T989D or if it's different in a way.
Sorry that I can't help, I hope you get the answers you are looking for

My brother used that method a long time ago and he was able to use different carriers, but now nothing works but Koodo, and I never get asked for an unlock code, just says 'No SIM card'

Yeah, this phone will not ask you for an unlock code, if you follow the procedure correctly it will read any other SIM card on it's own
Try unlocking again with what you have, the stock 4.0.4 and UVLE1 combination, it should be the right one. Do the procedure again until it reads the SIM card you want.
Another possible problem could be that your SIM is damaged or not well placed. It happens to me when I try to fit a Micro SIM on it, if it is not well placed it will not detect it. Try using other SIMs or try it on other phones to see if your SIM is the problem

I tried unlocking it again, doesn't work, tried different sims, and still doesn't work, but those other sims work on different devices. Only the Koodo one works on mine, which was what it was locked to before unlocking.

Well in that case I'm all out of ideas.
One final question, when you insert a SIM on your T989D that is NOT Koodo, do you get an "Invalid SIM", "No SIM" or just an empty signal bar?

It says "No SIM card.|Emergency calls only"

My conclusion is that it's having a hard time reading the SIM card. When you put another companies SIM card in to a LOCKED phone, it will show as invalid SIM (sometimes it even shows signal but is unusable). Since it says "No SIM card", I believe it's more of a hardware problem than a software one.
All I can think of is try moving the SIM card around, turn on. If nothing changes turn it off and move a little again, the turn on and repeat until it reads it.
Apart from that, I have no clue what could be wrong with the phone.
Turn on your phone without any SIM. If you get the same message (No SIM card.|Emergency calls only|) then it is most definitely your phone not reading your SIM correctly. If you get Koodo signal WITHOUT any SIM inserted (which I doubt but it CAN happen) then that means you have a faulty SIM Card Reader on your phone.

It works on Koodo but only if the sim is inserted, also I tried moving the sim around and it still isn't reading. I think this is a software issue.

Sorry man, I'm all out of ideas. I mean I've experienced the problem with the "No Service" thing, but I basically fix it by switching to 2G since I know there are some areas that I can't get 3G coverage. As for your problem, it's basically not reading your SIM entirely (by either software or hardware issues) and I wouldn't know how to get around that.
Best of luck to you

Help note 2 no sim card after 3rd party software

My Note 2 international was working well until i decided to flash a 3rd party rom.
When i flashed the rom everythong worked fine but the sim card.
The phone kept asking to insert sin card although it was already inserted.
The sim is working on other phones.
I tried flashing back the original 4.4.2 rom from sammobile and it worked and i could search for the networks and i selected my network and the phone said registered on network. But when i try to make a call it says again: not registered on network.
What should i do?
Please help.
Thank you
