An end user is away from the office and is traveling to a conference center to set up a corporate booth. Conference center calls and says that they haven't received their registration and that the end user needs to complete that right away or they will lose their booth space. The conference center's registration site is not compatible with mobile devices. The end user has their laptop but their laptop doesn't have a cellular card.
How can the end user effectively connect their laptop to the Internet, in order to complete their conference booth registration?
