OK. I'm going to try and be as thorough as possible here.
I have a Sony Ericsson Xperia r800at. It was on ATT service. I am wanting to switch over to Straight Talk.
I have a Straight Talk SIM card in the phone.
I am running Android version 2.3.3 (build 3.0.1.B.0.285)
In my research on how to unlock this phone, every site I see simply says to Turn off the phone, put in SIM card, and turn the Phone back on. When you go to swipe the phone to unlock it should prompt you to put in the SIM Network Unlock code.
I do not get this. It just lets me right in the phone. The only error I'm receiving is "SIM card not provisioned MM #2" in my notifications and the phone is telling me it can be used for Emergency calls ONLY.
Does anyone have any ideas on how I can get the SIM prompt to appear?

Hi guys,
A while back I tried to enter a sim unlock code with my T-Mobile sim card and this did not work. Now when I insert the SIM I just get an error MM#6 Not allowed. Is there any way I can get the screen/prompt to enter the SIM unlock again? I have tried a bunch of the *# numbers online but I have been unsuccessful in getting this screen to be displayed so I can enter a new SIM Unlock code. Thanks!

Not that it would really matter, but the guys in the AT&T forum may be more able to assist in this since your device is the AT&T device. Also, what ROM are you using when you try to enter the code? I do believe you have to be on a TouchWiz (custom or stock) not AOSP to enter that menu.

Try this, I am not sure that it will work but it will take you to the screen for network unlock
.Goto phone dailer, and enter *#27663368378# for the debug service menu.
In "ServiceMode", select [1] UMTS
In "UMTS MAIN MENU", select [1] DEBUG SCREEN
In "DEBUG SCREEN", select [6] PHONE CONTROL
In "PHONE CONTROL", select [6] NETWORK LOCK
Good luck!
Hi,
I have a SIM unlock code but when I insert a new SIM it doesn't prompt for the unlock code.
I don't know if it has something to do with the fact that my phone asks for the language every reboot and it "covers" the unlock screen.
Is there a hidden menu or USSD code that I can use for type in my SIM unlock code?
Cheers

You installed a KK version and have wrong baseband, kernel or something else wrong. Nothing you can do about it except flashing correctly according to the guide here in the forum.
I flashed the custom KK rom and had the same problem. Only by following the guide on how to install KK with locked dual recovery and root very exact, I got it working.
I thought that I followed the guide step by step but I'll give it another try
Thank you

Hi,
I don't have the "Sim card lock settings" in my Security menu.
but if I go to the "service Menu" - Service Info - Sim Lock y shows an X on "network" and a 5.
I think it means that it is locked and I have 5 unlock attempts.
BUT if I put a new SIM it doesn't recognize it and it doesn't prompt for an unlock code
Q u,z
Cheers
JD

Try this? I did this to unlock a ZL (Jellybean) last night (not intentionally, this is just the order in which we happened to do it).
1) Put in correct SIM (a SIM that has the carrier in which the phone is locked to)
2) Do the initial setup stuff to get it out of the way (this is so it doesn't bother you with it again and again)
3) Power off, put in illegal SIM, power on. It should ask for unlock code without anything overlapping it.
Baseband/modem I747UCUFNJ2, stock 4.4.2 rooted. Phone from AT&T working ok with Claro Brazil (code unlocked) . After upgrading, lost IMEI. Flashed new modem and IMEI and IMEISV ok now. Checked IMEI number, is the same printed behind battery on phone. But now can not make calls. Got message 'No SIM card'. Ordered a Sim card tray, replaced it, but got same message. Phone has strong carrier signal. After reading a lot, I ordered a paid unlock code, but seller stated that code doesnt work in android 4.2.2. Even though, I tried to insert it once. (#@7465625*638*# - have to use it since phone doesnt ask for code at starting). As stated by seller, got message 'unlocked unsucessfull'. So now, what can I do to unlock the fone ? I have access to a hiden menu by dialing *#197328640# , but dont know how to use it. I have read a lot during this week. Did no find any helpfull information. Any help will be apreciated. Sorry for my bad english.
Sounds like the baseband and bootloader and too new for the ROM. You probably need to upgrade from stock 4.2.2 to stock 4.4.2 or flash a custom ROM based on a TW-kernel.
I edited/corrected my wrong information. The phone is on 4.4.2 stock already.
Try this:
Method 1:
Go to the dial screen and press #7465625*638*#
Once prompted for code, enter 8 digit Unlock Code.
Method 2:
Turn off your Samsung phone
Insert a non-accepted sim card (different from the original carrier) and turn your phone back on.
When prompted for the unlock code type the UNFREEZE code provided. If you are not prompted, go to your dial screen and type the UNFREEZE code, now press enter, send or call. You will receive an unsuccesfull message, don't worry.
Once the phone freeze is disabled, the Network lock or SP Lock screen will appear
For Network lock enter the UNLOCK code provided. For SP Lock enter the SERVICE PROVIDER code
Your phone is now fully unlocked!
If you get "unsuccessful" again then hit Dismiss button and type *2767*3855# on phone keypad and try this procedure again (CAUTION! This will reformat all your data!).
Method 3:
You can try this method without the sim card or with the original sim card
Type #7465625*638*CODE# (CODE is the Unlock Code)
Phone deactivated message means its unlocked
I got an unlock code from AT&T for my Active. The instruction they send me is this:
1. Power off the device and remove the SIM card.
2. Power on the device.
3. Enter #0111*, the unlock code, and #. The device cycles off and back on.
However after step 3, nothing happens. I tried a couple times, press the dial button, nothing happened.
Can anyone help? Thanks
Put your AT&T SIM card back in the device, power it on, then make sure it's working with AT&T - this is assuming you have AT&T service, I hope, 'cause if not you could be somewhat stuck here.
Having said that, the process is fairly simple:
- power down the device with the AT&T SIM card inside it (as noted above, if this can't be done then again you could be stuck)
- take the AT&T SIM card out, put in a SIM card from whatever provider you're attempting to use the device with
- power on the device
- after the boot process is finished you should encounter this screen or something similar:
With a non-AT&T SIM card in the locked device that screen should appear every time you boot the device until you actually get it unlocked, if you're not seeing that screen then something odd is happening.
- if you do see that screen enter the code and BE VERY CAREFUL NOT TO MAKE ANY MISTAKES WHATSOEVER because you can only enter a code incorrectly a certain number of times after which the device will never be unlockable so, make sure you're accurate.
My Active is still network locked and I just put a T-Mobile nanoSIM in it, rebooted and voila, I get that screen. If you're not getting it then something is not right someplace, you might need to go to an actual AT&T store and see about having them assist you.
