Question about Samsung SGH-d407 Cellular Phone
I bought a rebel sim card so that I can unlock my iphone 3G using my T-mobile sim card. However, I need to reset the network keys on my t-mobile sim card using a 2G phone in order for the rebel sim card to work properly in my iphone 3G. So I have a Samsung SGH-D407 (an AT&T phone) and I tried to put my T-mobile sim card in it but it just tells me "Wrong Card." So now it seems that I need to be able to unlock the Samsung phone now in order to be able to reset the network keys on my T-mobile sim card so that I can, in turn, use the T-mobile sim card simultaneously with the rebel sim card in my iphone 3G in order for it to work.... Whew!!! So basically, I think I need an unlock code for the Samsung SGH-D407 to be able to move forward with this. Can someone please help me?
WOW! what a process! I don't know how you kept track of all that but , good job! Try this. It's a maybe, but better than nothing,
Put a non-accepted SIM Card and turn it on. Type *#9998*3323#. Press Exit. You will get a new menu. Select Malloc Fail.
