Do you have to register the phone to the network provider before you try to unlock SIM.
Like with Tmobile you get a SIM which you have to insert and register withe the network.
suppose i take a brand new packaged phone out of the America to my country say Thailnad where there is no T mobile , then can i unlock it there .
What i am asking is whether i can unlock the phone without having to first insert the T mobile SIM card and registering to their network .
If you cannot understand my qusetion please post and i will try to explain it again.
thanx.
