UUNET Technologies Inc.'s wireless Internet access service called UUmobile is now available in Atlanta and San Diego. The ISP plans to have the service available in 21 markets by year-end. The WorldCom subsidiary is also offering customers service bundles called Access Choice that will let them sign up for higher-bandwidth services with alternative dial-up connectivity in cities where wireless or DSL access is not available. There are three bundles. One couples UUmobile service and UUdial Internet access services. The second bundle couples UUlink DSL and dial-up services. These packages cost US$90 per month for unlimited access. The third bundle includes UUmobile, UUdial and UUlink services and costs $160 per month. The DSL modem is included, but customers will pay an additional $250 to $300 for an external wireless modem.
