Once you have a data plan, you must set up your email address or third-party instant messaging account in order to send
and receive email messages, use third-party instant messaging applications, and use some browser options.
If you are an individual user, when you set up your email address or instant messaging account, you are associating it with
the BlackBerry Internet Service.
If you are a corporate user, your administrator sets up your email account by associating it with a BlackBerry Enterprise
Server. Your administrator might set options that determine the features and settings that are available on your
smartphone and if you can add or update an app. You can view the IT policies that have been set by your administrator in
the security options on your smartphone.
Wireless network
The wireless network that your smartphone is connected to might affect the availability of some features. Depending on
your wireless service provider and available roaming options, different wireless networks are available. Some wireless
networks don't support features such as call blocking, call forwarding, or cell broadcasting. For more information, contact
your wireless service provider.
Region
Depending on your region, you might have the option to add or update apps using the BlackBerry World storefront
(previously known as BlackBerry App World). You might also be able to download apps from a webpage or an application.
The availability of certain apps varies by region.
