I did purchase an unlock code from unlock-code-central.com. Put a different SIM, typed in the code, got the message all went well, however phone says "emergency calls only"
Can anybody please help me with this?
Is my phone unlocked or not?

There was no need to purchase the code as there are several threads here on how to menu unlock it. But since we are beyond that, I'm guessing the other SIM is not provisioned and has no service on it. Try using a friends T-mobile SIM. That's how I was able to check the menu unlock method.

Thank you for your answer.
I used a regular size Vodafone SIM which I just used in Europe last month, on my other phone, so that SIM should be ok.
However I used a SIM cutter to transform in into a microSIM . Visually looks ok too. Could it be that in this process the SIM (now microSIM) got damaged somehow?
When I first insert it, I was prompted for the unlock code, which I typed, got an ok message, but that's about it.
Now says "emergency calls only" and it does NOT prompt me for the unlock code anymore.
Original ATT SIM works just fine.
There's more: I just put that Vodafone microSIM into my wife's phone (which is unlocked) and it works fine.
So bottom line, I used an unlock code which apparently worked (got the message "network unlock successful") but the phone does not appear to be unlocked.
I will definitely try a T-mobile SIM as soon as I find one, but in the meantime which is that "secret code" to check network status for this phone?
*#7465625# does not work and returns "connection problem or invalid MMI code"
Thank you

anybody has the answer to my question ?

code doesn't work

Hi,
I recently purchased a unlock code from unlockadic for my vibrant but when I went to use it it said Network lock request unsuccessful. Does anyone have any ideas?
If this is in the wrong section I apologize
P.S. I did contact unlockadic and said that this has never happened and that he would have to have his guys look at the problem.
bump because i had the same issue.
you need a non-t-mob sim in the phone for the unlock to activate
I have an account with Rogers & that is the SIM l put in the phone-result was unsuccessful. Code is correct unlock code-i got the same code from three different sources but no luck.

hussafilms is correct.
You need to put in a sim from a network that the phone was not designed for. So if you bought the phone from tmobile then put in a att sim or if you bought it from another company put in a sim that is not from that company. So if you have the galaxy s from rogers then put in a tmobile sim or something.
Let me clarify, I bought a Samsung t959 Vibrant from ebay locked to t mobile and I put in my Rogers SIM card, entered the code and it was unsucessful
How many times did you try to enter the unlock code? I beleive if you have three failed attempts, it will be permanatly locked.

sgh-i437 rooted and running cm-10.2-20130925-UNOFFICIAL-expressatt-still locked

I have a Samsung SGH-i437 that was a contract phone from AT&T. I wanted to unlock it for use over seas, so I rooted the phone and installed CyanogenMod cm-10.2-20130925-UNOFFICIAL-expressatt but the phone still has a carrier lock on it. I now have a unlock code but can not get the prompt by using #7465625*638*CODE# because it give me a no network message. When I insert a different sim it does not recognize it. It only has the icon for the sim with a ? make on it.
Any help would be appreciated!
4 days and no help!

D803 issues after unlocking... no service fml.

Hi,
I just unlocked my LG G2 D803 "originally with rogers" (CAN) using a unlock code that I purchased over the net.
Bell Sim Card now loaded and activated.
Once I restart the phone it says No Service..
I set the APN correctly
Still nothing, and it just keeps looking for the network. Oddly I receive a "New voice mail" notification.. I try and click it and just get.. Warning, emergency calls only.
What could be the issue?
Would downloading a custom rom and installing a new modem do any good?
Any help would be much appreciated.
Thanks guys
Sincerely,
Royce
For me when I unlocked my phone I had to enter the unlock code twice for the phone to unlock my D803... Just check from the secret menu... All options should say a message about being not personalized

Every one in that "secret menu" says my phone is not personalized. I'm pretty sure this means the phone is unlocked. I noticed other people having the exact same issue after unlocking their phone. Still cant find any solutions.
Solved...
The phones been blacklisted.
Anyone who is having similar issues.. this is most likely the case.

Can't write sim unlock code, please Help

Hi.
I bought a locked s8+ from Telcel México. I want it to use it on Att, I have the unlock aim code. The problem is when I instert the att sim I got a message "SIM network PIN blocked. Enter Sim network PUK." and a small lock blue icon. But I can't write anything, there is no keyboard option or anything. Any help? Thanks!
Have you tried another SIM card? Maybe read this: https://www.att.com/esupport/article.html#!/wireless/KM1000485

I just unlocked my phone this weekend. A number pad should have appeared. If you didn't turn off the phone to change the SIM try restarting. If that doesn't work try a different card.

Tried 2 different cards and had the same screen.
Now I flashed a new rom, that screen disappeared but now when I insert a new sim car got a new screen and now I can write the numbers. The problem is that I don't have the PUK code, I think that I need an unfreeze code, anyone knows how can i get that code? Or how can i unlock my phone?
Thank you!
Same **** with mine.

I got S8+ from f#c!¢n Telcel and paid for the Network Unlock code and have the same screen with the blue icon and cant do **** about it. With the new ROM ( Which one did you flash ) did you have any luck, have you unlocked your phone ?

You need the PUK code for the new sim card - most print this on the card that you popped the sim out of. If you don't have the original outer card, then call the carrier for the NEW sim card you are trying to use and they should be able to help you.

930A Flashed with 930U Unlock Question

I have a ATT 930A that I successfully flashed with 930U and it works great. I was thinking of making sure it was SIM unlocked in case later I wanted to sell it, so I made a request of ATT for the unlock code but when I try it it tells me the unlock was unsuccessful. Do I need to go back to 930A to make the code work?
Probably yes
I don't think so. Just put in a non AT&T SIM and it's gonna ask for an unlock code

I did but the code att gave me didn't work.
So did the phone prompt for a SIM unlock code and you typed it in, got an error? What is the error? SIM lock should not change when you flash different ROMs yo the phone.

Yes, after entering the code it says "incorrect network unlock code entered"
I had this problem with my S7. I had paid off my contract however every time I tried input my IMEI number to the AT&T unlock device website it would tell my my IMEI is invalid. i contacted AT&T customer service directly and gave them my informatio. They had to put the case in for the unlock code themselves. Reason was since i didn't finish the 2 years even though i paid off my contract it got lost in the system hope this helps
