Is there any way to unlock A56 or C56 from AT&T?

Is there anyway to unlock the AT&T Siemens Phones with out using cables? Dont want to buy an expensive box for just a few phones. Thanx in advance.

Hi,
There is no free soft that can unlock these phones. You will get message of unlock done successfully, but phone will be sdtill locked. You can unlock it with Martech, Dreambox or SST. But only will work for 850/1900(C56)
