If you encounter issues either during the installation of the BlackBerry Mobile Voice System or after you have installed the BlackBerry MVS, you can engage BlackBerry Technical Support in one of the following ways:
- Visit the BlackBerry Expert Support Center at www.blackberry.com/besc
- Telephone: +1 877.255.2377 (North America Toll-free) or +1 6474261108 (International)
When you are talking with BlackBerry Technical Support Services you must provide your subscriber code to gain access to technical support. The support analyst will request the data that you gathered in the preinstallation checklist topic and the site survey checklist topic, so be sure to have the information available.
