okee, talk to you carrier (mobile service provider). It may have different name(s) for BlackBerry services. In the UK, for example, one carrier calls it a BlackBerry bolt on, or something like that. But talk to your carrier. Make sure they know you want BlackBerry data service. It may be bundled with a voice plan, or an add on.
