CELLULAR TELEPHONE PHREAKING PHILE VOL 3 by "The Mad Phone-man" Now that you have become familiar with the technology of cellular phones its time to discuss what you can do with a phone right now. Not every system pays attention to a "Roamer" from outside the system as closely as they do a local suscriber. In their mad rush to offer cellular as "universal" service, meaning you can place a call in any cellular city any- where in North America, they fucked up. OK, heres the poop...I access say..Cleveland Ohio Cellular 1's Ericcson switch and tell them by my "NAM" info that im a roamer from NYNEX in New York City. Cleveland will let me make the call, cause it bills back to NYC my number of minutes used. If the NYC number is bogus, the call goes thru, and the bill doesn't go anywhere. They do know the exchange data for NYC, thats on a chart so ya cant tell em yer...555-1212 or such..you must tell em yer a valid roamer and the System number (two digits) must match NYC's. This is not too hard to figgure out, (call some of their stupid sales idiots some time and see what they will let out of the bag)...so now lets see what else you should know. OK, the system number for the foreign exchange....Nynex in Buffalo is 56, Chicago nonwireline is 01, Buffalo Nonwireline is 03, All wirelines are even numbers all non-wirelines are odd. OK, first three digits of the mobile number....Nynex Buffalo- 863 xxxx Buffalo Non-wire 861 xxxx, 690 xxxx. I am sure it wont take much to figgure out the local numbers for your area like I said the sales people are fucks and will tell ya anything to make a sale. Until the companys get a cellular clearinghouse to validate roamers in real t{w{e this will work out fine. The prospects of such a clearinghouse are good after the companys get done with their bitching at each other. But it may be a while before it becomes routine to look up a roamer. There's simply too many to look up every time service is wanted. So, steal a cellphone and his antenna, re-nam it as a roamer and when ya get it setup, make copies of the info with different suscriber numbers (the last 4 digits) and make free calls till whenever.
