"BlackBerry is still the only cell phone provider that bypasses the carriers for messaging," says Rob Enderle, principal analyst with Enderle Group. "Depending on Internet speed, you may be able to use an instant messaging technology, but it will need to be a secure form, the clients will need to be able to run the related software, and you'll likely need a low-latency guarantee of service from your carrier to get this to work."
At first blush, Apple's iMessage may look like a similar platform-specific messaging tool. But iMessage is essentially just SMS text messaging with a little extra Apple polish. BBM has much greater depth of features and is more secure, requiring users to do more than just provide someone's phone number in order to connect and chat.
BlackBerry intended to ease this transition by offering a BBM app for both iOS and Android. The app would have enabled an organization to begin switching to one or both of those platforms, while maintaining the security, reliability, and familiarity of BBM. The apps are currently on hold, however, following a botched launch that caused BlackBerry to pull the whole thing for the time being.
4. Data protection
BlackBerry is synonymous with mobile security. BlackBerry customers are accustomed to end-to-end encryption out of the box and built-in data protection technologies to secure company data against unauthorized access.
Android, iOS, and Windows Phone are—first and foremost—consumer devices. They can function as well as or better than BlackBerry mobile devices in many business and productivity roles, but they treat things like encryption and data protection more as options than as default features.
As you assess your mobile platform options for replacing BlackBerry, consider how each handles the critical job of protecting data—both on the device itself and during its transfer across the airwaves. Make sure that the inherent security features and capabilities of the mobile platform you choose meet your needs, and confirm that your IT admin will be able to manage and enforce security policies on the mobile devices involved.
5. Alternative apps
Good Technology's Dasher stresses that apps are crucial, and should play a significant role in your choice of a mobile platform to replace BlackBerry. "Your BlackBerry is likely used for email, calendar and contacts. In the destination plan, think about the additional apps that are needed to ensure employee productivity."
List all of the BlackBerry apps you depend on: email, contacts, calendar, CRM (customer relationship management), VPN, and any others. Then determine whether those same apps are available on other mobile platforms.
If they're not, you'll have to do additional research to find appropriate alternatives. If you plan to migrate by attrition, make sure that the alternative app can work alongside the BlackBerry app; and check to see whether you can integrate or transfer data from the old app to the new one to smooth the transition.
