With BBM Chat, you will be able to carry on conversations WhatsApp-style: you’ll be informed whether sent messages have been received, read and whether the recipient is writing you back. You’ll also be able to leave voice messages and send files, conduct multi-chat – which allows for conversations with more than one person at a time – and in rushed cases, send the same messages to many contacts simultaneously.
A PIN, which will belong to each user individually, should ensure for security and privacy so that your phone number and email address aren’t in danger.
BlackBerry Messenger for Android should be released a few days before the iOS version.
Do you plan on switching from WhatsApp or Facebook Messenger to BlackBerry? Personally I use both WhatsApp and Facebook Messenger, though I find the first to be better, albeit liking the Chat Heads from FB. I plan on trying BBM to see if it toots my whistle.
