If you want to unlock your phone put a SIM from another Network, then type:
*#9998*3323# it will reset your phone.
Press exit and then press 7, it will reset again.
Put your other SIM in and it will say simlock, type in:
00000000 then it should be unlocked.
Type in *0141# then the call button and it's unlocked to all networks.

This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing: *#2767*2878# or *#9998*3855# (not tested)

You do this unlock procedure at your own risks.

I purchased a sim card from tmobile to replace my att simcard on my samsung SGH-A707.The new sim card won't work,it sy's incorrect sim and networt lock.


Hello

The sim wont work because it is locked to the att network which means it will only work with att sim cards.

You will have to unlock the phone from the att network before it can work with the T mobile sim card

You should contact your network provider so as to get steps to unlocking your phone from the att network or you should contact a repairer to help you unlock it

Thank you for visiting fixya

This will also bring the phone to default settings 1. First do a CUSTOM reset: *2767*2878# (star 2767 star 2878 hash)
turn off the phone 2. take out the battery and sim and put wrong network SIM and insert a half of it,
so it won't ask for network password and shows "Insert SIM" message.
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.) 3.With out turn off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM" 4. Make a FULL reset by typing: *2767*3855#(star 2767 star 3855 hash) 5. The phone should reboot working with "wrong" sim inside. 6. Make a Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#

Samsung d900i on o2 network


O2 won't help because they do not want to lose a customer. There are lot's of phone shops and market stalls that unlock phones between £5-£8 and you will be able to insert any sim you like then and won't be stuck to one provider. I get all my phones unlocked so I have the freedom of networks


I hope this helps

Unlock Samsung sgh-t619


To get your IMEI no your mobile you need to use the following code *#06# This will display the IMEI number of your mobile
-----------------------------
How to Unlock Samsung T619:
What you need to start is your Samsung T619 and a NON TMobile sim card. You can borrow a friend’s if you need one.

1 - Power the phone off
2. Remove the TMobile sim card
3. Insert the NON-TMobile sim card and replace the battery.
4- Turn on the phone, “wrong sim” should appear on the screen.
5-Dial *2767*3855# and wait. It could take the phone a few seconds to reboot. The phone will reboot,and the non T-Mobile SIM card in the phone will work,but this is only a TEMPORARY unlock step
6-Dial <span>*7465625*638*00000000*00000000# phone will say it is personalized.
7-Dial #7465625*638*00000000# The phone is now unlocked permanently.
8-Dial *#7465625# to check the lock status.
