Unlocking the sim for AT&T

I recently called up at&t and told them I was going over seas and i had an extra sim ( I dont really have an extra one ) and they proceeded to give me a code which to unlock the other sim. My question is am I able to unlock my current at&t sim with that code, and if so how can I do that?
Thanks

If you want your phone to work on any carrier network and to be able to use prepaid SIM cards just borrow from a friend a non att SIM card (like T-mobile).
Power down your phone; insert the "alien" SIM card; power up.
The phone will request you to enter the unlock code. Enter it. Remember that you have only 5 attempts otherwise the phone will be permanently locked to ATT and there is no EASY way to unlock it.
When finished, swap the cards and you are done.

thanks alot man, i just did that and it seemed to work. i just put my original sim back in, is there any way to verify that my phone is unlocked?

lol, put that other non-AT&T sim back in

1st of all thank you for replaying in my thread .
with regarding of the SIM card i have done that i treed using our network SIM card (Mobaily) and nothing happen .
I treed this :
A)-
Turn your phone with a non accepted simcard, and then turn off the wifi.
Now go the dial screen and then type *2767*3855# on phone keypad. (CAUTION! This will reformat all your data!)
1. After phone restarts, type the Unfreeze code ( ) when prompted to enter "SIM network unlock PIN" or "Enter Network Lock Control Key" screen and hit unlock button.
It will say "unsuccessful" again, don't worry!
2.. Type the Unlock code ( ) and hit Unlock button.
3. Your phone should now give you the message "Network Lock Successful"
Now your phone is successfully unlocked!
If there is still an error please press *#06# and check the IMEI number
B)-
Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)
Q: is it poseble to get dial screen on this tab ?
thanks .

With my 8.9 LTE, I power up with a sim card, and it asks me for the network lock right away. Is that the same as the sim lock? I've never unlocked a tablet before, but I'm assuming it is. Tablets surely can't have the multiple lock menus a cellphone has. Network/Sim/SPCK etc.
To trigger the unlock menu, you need to insert a NON-compatible sim card. So if your tablet is a MOBAILY one, inserting a sim of that company won't help you.
Put in ANY other sim to get the menu to pop up.
Good Luck!
btw, those instructions are for a phone., hence the dialer. I'm willing to bet it 99.9999%. AFAIK, there's no way to get a phone dialer menu on a tablet lol. (watch me be proven wrong ha):laugh:

[Q] ATIV S Neo (SPH-i800) Sprint SIM Unlock

Hey guys,
I am in Spain. I asked Sprint to SIM unlock my phone before I left and they said it worked but it did not. I bought a movistar SIM and all I get is 'no service.' Under Cellular+SIM options, it is in CDMA only mode and the option to change it is greyed out. I was in 8.1 so I flashed to 8.0.10328.78 and called Sprint. They want me to update my network profile to send the command to unlock it but it isn't working over WiFi.
The phone knows that the SIM is there, I can access the SIM applications, read the SIM ID and when I turn on the phone with it inserted it says 'switched to CDMA only.' So I think it is still SIM locked. Is there a way I can unlock it? I've never had to deal with this before.

No ideas? I need to know whether I should give up and try to return the plan I bought.

Can Sprint version Ativ S neo unlock ?

Agreed
Just adding to the overall knowledge base here.
I am experiencing the exact same problem.
1. I purchased my phone unlocked (though it was previously on Sprint). I have previously been able to use foreign SIM cards (in France), without issue.
2. At some point, I installed the Developer's Preview of WP8.1 and lost the ability to roam domestically or internationally.
3. I am now in Israel, and tried an Israeli SIM card, but it was on a GSM network. It connected to the network, but showed up as international roaming. Ooops, guess I need to fix that little WP8.1 Beta issue...
4. I decided to flash my phone back to WP8 GDR3, which seems to have un-unlocked my phone. Now when I plug my Israeli SIM card in, my phone automatically switches to CDMA mode.
5. However, if I pop a Sprint SIM card in, I have the ability to switch to Global Mode again.
I have the MSL, but I cannot figure out where I would enter it to get this to stop happening.
FYI.

I had a problem , I live in Ukraine , my phone was unlocked , but when I installed 8.0 my phone worked only in CDMA mode with a Sim card from my service , I updated to 8.1 again using the preview for developers and settings again appeared global regime.

[Q] AOSP, 4G, and Sim Card

OK, sorry if this has been addressed somewhere directly but after nearly 2 days of banging my head around the forums and google I can't seem to find a solution intended for my purpose....
Basically, I have yet to find an AOSP Rom(which i heavily prefer to Sense Roms) that recognizes my Sim Card and will, therefore, pick up 4G as the Sim is a requirement for 4G with this phone...
I can run Insert Coin and pick up 4G just fine but I do have to unlock the Sim with a Pin(which I apparently thought it was good to place on the Sim at the time) everytime I reboot my phone.
Before placing a Pin on the Sim Card I did not experience this issue. However, I see no way at all to reverse the damage. I can force lock it with the wrong Pin, enter the PUK code I got from Sprint, and then put a new Pin but the new Pin still has to be 4 characters (was hoping I could just do a blank one).
To further complicate things, the stock Rom (latest or each version back through to 1.15) doesn't even have a Sim Card lock setup section in the Security preferences of the Settings menu for the phone.....which is what HTC told the Sprint technician I should do to "unlock" my Sim Card and remove the Pin.
When I run some of the AOSP Roms, Paranoid Beta or Pacman for examples, I do see the Sim Card Lock Setup in the Security settings, however, it is grayed out and unclickable....as if there isn't a Sim or it cannot access the one that's there....probably the latter as if I remove the Sim that section of the settings disappears upon refresh.
All I want is to be able to pick up 4G with, preferably, Paranoid Beta or Gummy Rom.. Does anyone please know how I can accomplish this? Do I need an entirely new Sim Card that hasn't had a Pin put onto it? Can I flash something that will actually have a working Sim Card Lock Setup for my Sim card that was already setup through a different Rom?(Don't remember which one I used initially but I think it was Stock or Sense-based at least).
Thank you very much for any help you can provide and for your time in reading about my issue.
Regards,
Guy Who Really Wants 4G on AOSP as it is Also His Only Source of Internet at Home and He Can't Stand Blinkfeed or Uncustomizable Nav Bars.

Mods can close this if needed. Resolved the issue FINALLY!!!!!!! Whoooooo!!!!!!!!!! YAAAAAAAYYYYYY!!!!!! lol
The Answer in case anoyone else has this occur (one of these two actions did it or both together )
- Used Captain Throwback's GPE 4.4.4 Edition Rom, however, before installing I purposefully locked the Sim Card via incorrect Pin, then when it asked me for the PUK I popped the card out of contact with its reader (slid it out of the phone a few centimeters) rebooted to recovery, reinserted the Sim Card, installed GPE.
When GPE first loaded I was prompted to unlock the Sim which I then did using the PUK I had ready, assigned a new Pin, finished Rom setup, then went to Security and BAM, the option was finally selectable to Setup Sim Card Lock.....all I had to do after clicking that was remove the checkmark next to Lock Sim Card =D =D =D
Thank you for being a part of my struggle, readers, I'd like to think you were rooting for me. =)
Sidenote: as you can tell I...get around...the Roms on here so it may well have been Captain's that I first placed the Pin on the Sim Card with so perhaps that would explain it as well but can't recall for certain....

Sony SOG01 Simlock Or...(please read the thread)

Hi all. I hope someone can help me with my phone.
I have this phone and I have problems with it. The phone was bought from another person, not in a store.
It does not connect to the mobile network and cannot connect to the mobile internet.
It is fully operational, all functions work (except for the sim card), the phone connects to wifi and connects to the Internet. When connected to a computer, it is also completely determined.
You ask, "So what's the problem, take it to repair, they will replace the SIM card module and everything will be fine"
The problem is this. The SIM card is fully defined in the phone. When installing a sim card, a reboot is triggered, the operator is determined in the settings menu (I am from Russia, therefore my operator TELE2, the sim card was bought specifically in order to exclude the old generation of sim cards and also a possible simlock to my other operator), but when you click on the sim card menu, calls and SMS the buttons are grayed out with the caption "temporarily unavailable" (if necessary for understanding, I will change the language of the phone and provide all screenshots of the system) and they cannot be clicked.
Also, in the engineering menu, in the simlock button, opposite the Network subset inscription, there is the number 5 and it is marked with the letter X. This means, as far as I know, that there is a lock on a specific operator. But after a hard reset, the phone does not ask for any codes to enter.
This is my question, how can this be fixed?
Will flashing the phone to global rom help?
I gave the phone to a service center (not a Sony branded center, we don’t have one in our city), they told me that software setup was needed, but there was only a chance to restore the phone.
Maybe I need root access and find some file in my phone?
Please help me.
P.S. I don't have the best English, so sometimes I can't understand you, please don't get mad at me)
P.S.S. I created this topic in the questions section. I'm sorry if I had to go to the firmware section
