Ok, there should be an option though. Just to clarify, I don't mean disable the phone all together forever, I just mean temportarily turn the phone wireless off and still use data during that time.
I know on other Blackberries, Verizon & other carriers can disable the "voice features" of a phone for hearing Impaired individuals. Preventing the phone from making or receiving voice calsl while leaving data transmission(Text/Email/Internet) intact.
It can be a pain to do so as many CSRs don't know this option exists. Also some less reputable CSRs don't want to do so because including the voice charges when setting up an account obviously makes a bigger sale.
