[Q] Unlocked SGS 4G not accepting foreign SIM - Samsung Galaxy S (4G Model)

Hi guys
so I unlocked my sim using the dd + hex method. a *#7465625# shows all the locks are off. When I put in an ATT sim card, I get an X where the signal indicator should be and when I go to "Mobile Networks" in settings it says "Insert SIM card to access network services". I'm positive the sim is good because it works in my other ATT phone.
Please help. KJ6 team kang rooted.

I hope you have a backup of your /efs partition. I don't recommend you ever edit the files directly. Look for my carrier unlocker if you can restore your backup and try unlocking your phone using the dialog that comes with the phone

No I unlocked the phone by finding the code in a hex editor and using the phone's dialog to do it. I used the method described in http://forum.xda-developers.com/showthread.php?t=980157

CustomROM in a unlock SIM Captivate

Hello,
I bought a Captivate in USA, the cell works fine in my country (Chile). I want to install a customrom, but I don't know if it's possible considerating the problem of the Sim.
I appreciated if you help me
Thanks

Hi, i bought a factory unlocked captivate from USA and never had a problem with custom roms. The sim never got relocked and i had flash over 20 roms on my phone. And i live in Argentina, without any access to an AT&T sim.
Though i would suggest, that you try to get your unlock code written down somewhere before you do custom roms, specially if you did not buy it factory unlocked. There is an app that gets the unlock code for you, I can't recall its name. Some of the phones get relocked after going back to stock; though I'm not sure if it is because they where manually unlocked instead of factory unlocked. What I do know is that when i tried to get my unlock code it wasn't anywhere, so I started flashing the phone hoping it didn't get sim locked.
If you don't get the code, flash and get sim locked there are several posts that explain how to unlock your phone. Those and the "universal sim unlock" gave me some peace of mind at the time.
Thanks!

Back up your efs directory. It is possible to relock and be stuck if you don't. There is no factory unlock captivate. All are att and have to be unlocked via code.

If it's prompting you to put in your SIM, try this: http://forum.xda-developers.com/showthread.php?t=1400890
If that does not help then more than likely your SIM is not making good contact, the SIM is bad, or the slot for the SIM is bad.
Imei all zeros? Settings > about phone > status...

Sim Network Unlocking Problems

I am trying to sim network unlock my One XL from AT&T to use on vodacom in south africa while on vacation. I am rooted and have CM10 09/26 nightly installed and Baseband 0.19as.32.09.11_2_10.105.32.25L (not sure if these make a difference trying to provide as much info as possible). I removed my AT&T sim, put in the vodacom sim was prompted for the sim network unlock pin and a proceeded to enter the pin. I received an incorrect error.
I used http://www.HTCimeiUnlockCodes.com/ to get the code and have double checked (triple checked) that I entered the correct IMEI number but still no go.
Any ideas or advice? Is it possible that the ROM/Radio affects this process at all?
Do a factory reset and retry.....all I can think of.

Take a video of the process you followed and send it to the code provider and ask them to reissue a new one or refund the money...don't try entering the code too many times..phone gets blocked...

[Q] Not prompted for SIM unlock code (Inspire)

I'm trying to unlock my HTC Inspire. I already have the code but all the directions I find say "Insert a non accepted SIM & reboot" I stick in a non AT&T SIm (Straight Talk SIM), reboot & nothing happens, no prompt. Is there another way to get to the SIM network unlock prompt?
There is no need to unlock for straight talk. If you picked the att compatible sim it will automatically recognize it and work. you just have to enter the apn for data
Please post all questions in the Q & A section. Thanks! Thread moved.

Ahh, OK. Thanks. Though, I wish I would have known this before I bought my unlock code. But, it only cost me $7.50 so no biggie. I'll just save if for the future. Thanks again guys!

no matter what combinations i try i cannot get a tmobile signal. when i start the phone up with the tmobile sim card in it it gives me the message "phone not allowed MM#6. when i set the APN nothing changes when ever i try to make a call i get the message "not registered on network" and when i try to register on the network and go back to the phone, i get the same message.

Does the IMEI display correctly when *#06# is dialed? If not, mostly likely a corrupt EFS which can sometimes be fixed with: this
i will try to enter the unlock code on when i flash a ROM but i am pretty sure that whenever i entered my unlock code it permentantly unlocked my phone. also my IMEI is displayed correctly when i dial that number, however i did not have the tmo sim card in when i entered it. i will try again with the tmobile sim card in there and see what happens. thanks for your responses

If the IMEI displayed without SIM card its fine. A stock ROM is required to enter the unlock code. The phone should prompt for the unlock code when booted with the TMO SIM card. After unlocking on stock ROM any other ROM can be flashed and the phone will remain unlocked. As a check, you should be able to get EDGE data on stock GB or ICS after unlocking. Then experiment with other ROMs/radios after verifying data on stock.

I cannot enter the unlock code again. I flashed a new rom and put my tmobile sim card in and the the phone does not ask me enter the unlock code again. Also whenever I put my tmobile sim card in the new voicemail icon pops up but I cannot call voicemail or anyone else because it still says not registered on network.
Maybe you need an unlocked radio. The radio may be locked on the US frequencies and preventing from using the other bands...

Btw, you only need to unlock your phone once. Flashing other ROMs or radios does not re-lock the phone.

I have just put the latest jb cm10 software on my skyrocket and I have noticed that my lte is gone? Is anyone having this issue besides me?

OP, someone, google the response and see what it is first shot. Why so difficult?
Here's one of the hits:
http://forums.crackberry.com/blackberry-curve-3g-f216/phone-not-allowed-mm6-728778/
This clearly explains why the OP can't connect to T-Mo network, and it has absolutely nothing to do with bands, radio, or whatever.
