Simple method has you using BBM for iOS and BBM for Android right now27
We are now going to give you a technique that will allow you to use the messaging app right away. First, you need to install BBM on your phone. That should not be a problem. If you own an Apple iPhone or Apple iPad, head to the App Store. If you own an Android device, go to the Google Play Store. Once the app is open, enter your email address as requested, click on Next and then force close the app. On iOS, you can force close the BBM app by performing a double tap on the home button and then swiping the app away. You can force close the BBM app on Android by going to the multitasking menu and swiping away the app. Or, go to Settings> Apps> BBM> Force Close.
Once you've closed the app, reopen it and you will have a unique PIN number. These are the numbers used instead of phone numbers or email addresses so that other people can get in touch with you. Using PIN numbers keeps your phone number and email address safe and secure. Have fun while it lasts because now that this is in the open, BlackBerry could close this glitch. By that time, however, you should have made it to the front of the line anyway.
