MCI and Sprint don't accept their own calling card numbers for use with 10xxx. They accept only your BOC card number, also known to many people as their AT&T card number (since these numbers are shared). As a guess ... MCI and Sprint figure most people won't use 10xxx, but rather simply 0+, from whatever nonhome phone they're calling from. They need to be able to take a universal-type card with any phones for which they are the default carrier, and the card number that makes sense is the one that most people have (a BOC/AT&T card number). Sure, they could accept their own card numbers as an alternative. But they don't want people to get confused about why their card number works "sometimes" (with phones for which "their" carrier is the default LD carrier) and not "other times" (with phones using some other carrier). They also don't want people to get into the habit of dialing just 0+ from a pay phone, since this will result in a substantial loss of business to the aforementioned other carriers. ("Gee, my MCI card didn't work here ... well, let's try my NETel card ..." Result: Customer is billed by slimy AOS, or perhaps AT&T or Sprint. All three scenarios are equally bad as far as MCI is concerned.) So MCI and Sprint make sure you always dial their 950- or 800 number to use their card when away from home. Since a 10xxx-0- call is treated the same as a "regular" 0- call at the carrier level, those who like 10xxx lose out if they want to use their MCI or Sprint card on such a call. The BOC card number will work, but will (always?) result in casual billing through the BOC rather than through your MCI or Sprint account. Carol Springs carols@drilex.dri.mgh.com
