    the imei is ; 357981013588181
    I have tried another sim card.
    as
    I stated this phone was claim to work on t-mobile the girl sent me some
    number I entered it and it did something but still no network, as
    stated before att said I have coverage and it should be working on the
    network

  • cristinaox Jun 27, 2008

    what are you calling a local phone company? I have att and they will not have anything to do with the phone since it doesn't have att logo. it has no logo.
    so what now? your solution is that you have no solution?


  • cristinaox Jun 27, 2008

    this is the numbers I have already tried, maybe I can find some somewhere who can test it. if thats not the solution, I will be back
    Thanks

Hi,

You must first call ATT wireless customer service to enable your wireless service.

Type in *#06# to see your imei, if its 000000000000000 then send it back.

Can you try another sim card on the phone?

    Ok, the imei code is normal and hasn't been changed to all zeros which would make it unusable.



    I suggest you take the phone to a local phone shop or a serice center to be tested.



  • Ekse Jun 27, 2008

    Take it to any local phone shop with you to be tested, the places that sell phones can test them, if not they can direct you to a service center.





    You can try



    *2767*3855# = Full Reset (Caution every stored data will be deleted.)
    *2767*2878# = Custom Reset
    *2767*927# = Wap Reset



    It may be a hardware failure thats why Im directing you to someone who can test the phone, we can't do that over the internet.

Unlock the samsung- sgh-a137


If you've unsuccessfully entered the PUK 10 times, the SIM Card is permanently locked. If not, then this solution is free from ATT, assuming you have ATT.

You can get your PUK code online by following these steps:
  1. Log in to your myWireless Account.
  2. Select My Services under My Account.
  3. From the My Services screen, select My Phone/Device.
  4. Select Unblock SIM Card.
  5. The Unblock SIM screen will display your PUK code.

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

I need an unlock code for a samsung impression i had att butnow i have t mobile


Hey welcome to fixya, i hope u 'll be fine. to unlock your cell try this solution

First do a CUSTOM reset: *2767*2878#
turn off the phone
Now Take out the battery and sim and put wrong network SIM and insert only a half of it,
Very important so it won't ask for network password and shows "Insert SIM" message.(possibly in a different language)
Now put the battery again,and switch the phone on .(phone 'll show "Insert SIM" message.)
Push the sim fully in at this stage the phone is still asking to "Insert SIM"
NowMake a FULL reset: *2767*3855#
The phone should reboot working with wrong sim inside.
Make a Change the password to 8 zeros by typing: *7465625*638*00000000*00000000#
Now Disable network lock By typing: #7465625*638*00000000#
Phone is unlocked


Note : Please keep back up of your files before unlocking
This will also bring the phone to default settings

You can also try another solution from here

I hope this solution 'll helpful for u. Best of luck

MY SAMSUNG SGH-F250 IS LOCKED AND DISPLAY NETWORK LOCK WHEN I INSERT NEW SIM


Hi,
1rs take the sim off and turn on the phone put this code: #*7337# , done the phone will be temporary unlocked.now insert a sim different from the phone provider (dont worry about to take the battery off), it will be unlocked but you have to tipe this: 
*7465625*638*00000000*00000000# 
then this one:
#7465625*638*00000000# 
and you have to check all locks are inactive taping this code: *#7465625#

!!!REMEMBER ABSOLUTELY NO WARRANTY THE BEST YOU CAN DO IS GO TO SPECIALIZED SHOP AND PAY FOR SAFE UNLOCK!!! 

But if something goes wrong you can allways go there to get new firmware & unlock your phone.

Good luck :-)

Samsung sgh-x426


I also have a x426 from 2003 and it wont work with the new ATT sim cards either, This is because of the Cingular/ATT merger which created a new network. The older original ATT phone must be unlocked to use a sim card from the new merged network. Try calling ATT Mobility customer service and request the subsidy unlock code. They are required to give it to you upon request, but it takes several days usually to get the code. I know because I used to work at a ATT call center.
