Question about Samsung SGH-D900 Cellular Phone

Using an AT&T SIM card in a T-mobile phone

The Samsung I chose to go with my AT&T plan got water damage and it would cost more than $120 to replace it. I can't get an upgrade for 18 months. My local AT&T center suggested that I just go to target and get a cheaper prepaid phone and then put in my AT&T Sim card. So I just bought a T-Mobile Samsung (t219) and put in the Sim card and now it tells me that I have the wrong card in it.

Is there a way to override the provider association on a phone and just use it as a piece of hardware with whatever Sim card I choose? If so, how do I do this?

Thanks

Yeah, you need something known as a Network unlock code. This can be obtained from T-mobile and the code should unlock the phone for use with other networks. There may be a charge for this.

Alternatively markets do this for free on occasion.

My Samsung Galaxy S2 GT-I9000 doesn't read my SIM Card


Can't figure out exactly what the problem is. Try with the following methods.
1) The SIM card might be damaged. To check this, Try inserting the SIM card into any other active network free phone. If it doesn't work then sure the SIM card is damaged. If it works fine then the SIM card is in good condition.
2) The SIM port on your phone might be damaged. Try inserting any other active SIM card to it. If it doesn't work, then sure the SIM port is damaged. If it work fine, Then the SIM port is in good condition.
3) The phone might be network locked. If the phone doesn't allow any network SIM cards to work with it except any one specific SIM card, Then it is sure network locked. You can unlock a Samsung Galaxy S2 safer and easier using unlock code. You can get the unlock code for a Samsung Galaxy S2 from ProUnlocking.Com at affordable cost with easy unlocking guide. Good luck.

Hi
PUK code is called as PERSONNAL UNBLOCKING KEY.
Your phone will ask for PUK code when you entered the PIN code wrongly several times depending upon the mobile make. The mobile asks for PUK code so that unauthorized persons do not use your mobile for wrong cause.
To get PUK code please contact your service provider through phone or go directly to their office. They will provide you the PUK code for your mobile. The PUK code for mobile phone.so that you can open your phone. When you planning to call your service provider you cannot use your mobile as it is fully locked. Please use some other mobile with same network to call your service provider.
While you get the PUK code ,the service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only. If they are satisfied with your answers they will provide with the PUK code
DONOT enter the PUK code several times wrongly,It will block your sim card permanently.
This PUK code is FREE. You no need to pay any sum to get the PUK code
Thank You.

Dropped samsung wave mobile in water dried and then tried to turn on but will not respond and does not appear to be taking charge what can I do


well the phone will not be accepted under one year warranty because it was damaged by the consumer (not a factory malfunction). Usually the only thing you will be able to do is file an insurance claim through your provider (if you chose to take insurance on the device when you bought it). The next step would be to take it to a store in your area with a technician or go to the store and buy a phone used or just outright. Depending on what carrier you have sometimes (like with at & t) phones you can take your sim card out and just pop it into any other At & T phone to use until your contract is eligible to renew.

I have a Nokia 1209 mobile which display -INSERT SIM \r\n Complaints only in this plan BSNL sim . I already buy duplicate sim twice . If i insert another plan sim no problem . Lastly i replaced sim...


Try with another sim card, clean the sim connector of your phone, reset you phone to Factory Setting (default) using 12345. If you can open it, clean the mobile thoroughly using iPhone solution. This problem is caused by Firmware problem and Hardware problem as well.
OR:
New Software Reinstall in the Phone
