There are two types of wireless networks: GSM and CDMA. All GSM phones require SIM cards because of the way a GSM network works. I am guessing that by "GoPhone," you mean AT&T's pay-as-you-go phone service, and AT&T runs on a GSM network, so any AT&T phones, including the GoPhones, require SIM cards.
