BlackBerry Messenger right now can send a message that has time period for the receiver to read the message. It’s known as BBM Timed Messages. By this feature, you can set the time of a message to be able to read before it’s automatically deleted. It’s like a timer message. You can control how long the message appears to your contact. This’s including the text messages and also picture messages.
Moreover, just like snap-chat, BBM also has message retraction. It’s a message that can be removed by a sender before or after it’s been read by the receiver. Therefore, the message is no longer appears on the history of chat. But there are some condition that may make these Timed Message and Message Retraction can’t be used:
First: In order to be able to use the Timed Messages and Message Retraction (TM & MR), you must install the latest version of BlackBerry Messenger. Even though your smartphone is a brand new device that already installed with BBM, but there is no guarantee that you can use the TM & MR if you don’t install the BBM version that supported these features.
Second: Even though you have a supported BBM version, you also need to make sure that the recipient (your contact name of BBM that you want to send a message) also has the same BBM version that support Timed Messages and Message Retraction.
Third: Better Internet connection is absolutely needed. Sometime you can’t use the TM & MR because of the internet connection established in your device is too slow. For example under GMS or GPRS networks. You need to get a better connection to be able to use TM & MR. Wi-Fi, 3G, and 4G are recommended connection.
Fourth: The device is too old fashioned. If you Blackberry that you used is an old version, including the hardware, there is high posibility that you can’t use the features of the latest BBM (TM & MR). This because the device unable to process the applications, or the hardware failed due to RAM problem. This problem is also occurred for BBM that installed on low-end Android device.
