Samsung unlock code


Hi,

This is true.. the problem with tracfones is that they are very hard to unlock..
You could try by unlock codes at http://www.unlocksamsungonline.com/samsung-unlock-codes/

however by cable will not work. Before you purchase any unlock by codes service check if you can enter the unlock codes.

Put a different simcard in the phone and turn it on. Then let me know exactly what the phone says..

Hi there,i had purchased htc thunder bolt a month ago from Miami US and since it was a lock piece i also bought unlock code online.Now the biggest challenge i am facing is when i put my local active sim...


Hi, i think your step not correct when entering HTC Thunderbolt unlock code. You must use your old sim card to unlock your phone, don't use new sim card before that phones completely unlocked. That's why your sim card not recognized. If this method not working maybe you get wrong HTC unlock code, since it's little rare for me. Usually if you bought unlock code reputable online store, they usually send unlock code with complete instruction how to insert that unlock code in your phones. The bottom line try my method and if not working get new code. Thanks.

NB: don't enter your wrong code to many times in your phones, it will caused your HTC to hard locked state and you can't use that phone even you put your old sim card.

IT SAY SIM LOCK AND ASKING THE CODE


This may not work on all Samsung phones!
THIS IS THE TEMP UNLOCK CODE FOR A SAMSUNG PHONE
Do this at your own risk:
Instructions
Press *#06# and write down your IMEI
Unlock Codes
Code 1: *2767*688 then your IMEI and then press #
For example *2767*688352708000828246# (Everything before the / for C225)
Code 2: *0141#
Code 3: 00000000 (8 zero's)
Entering the Codes
1. Switch your phone off. Remove the original SIM card 2. Insert another SIM card from an alternative network. Power up your phone. You should now see the "Wrong Card" message. 3. Type Code 1 into your phone, if this is entered correctly your
phone screen should now turn black and reboot itself. (C225 doesn't go
black but does reboot) 4. After the phone reboots the SIM card will be recognized and your
SIM will work. Be patient while your phone reboots and DO NOT press
any keys. At this point the phone is "Temporarily" unlocked.
5. Now at your idle screen type in Code 2 (*0141#) and hit the call button.
This should give you a message saying the phone is "Personalized". 6. Power off the phone and insert the original SIM, then power up. 7. At the SIM code prompt, it will ask you to enter a password. At
this stage enter Code 3. 8. After entering hit "OK" and your phone should complete initialization.

7. At the SIM code prompt, it will ask you to enter a password. At
this stage enter Code 3.

8. After entering hit "OK" and your phone should complete initialization.

Your phone is now Permanently unlocked.

Another easy way is you put in a foreign sim put in the code *2767*2878# much easier and works just the same.


*2767*688 <your IMEI number>

When i put my sim card into my blackberry it says invalid sim... what is going on? It's an unlocked phone I purchased on the internet and it is not working... can anyone help me?


Hello,

It looks like the telephone is SIM locked.

If you go to Options > Advanced Options > SIM Card and type MEPD.

This will bring up another screen. If the Network option shows "Disabled" then it is unlocked.

If its locked go back to the seller or buy an unlock code online.

Hope it helped.

I just got my puk code unlocked with 01234567


you have entered the pin code wrong 3 times now you are required to enter a puk code to reset the pin code. 

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code. 


if you have entered the puk code wrong too many times you will make the sim card useless and you will have to contact your phone service provider for a new sim card, it will probably cost.
