Just as the name implies, Flash SMS is a type of SMS that appears automatically on a recipient’s phone screen without any form of interaction from the receiver. In other words, contrary to regular plain SMS that gets delivered inbox on a phone and the receiver has to open the message to read the contents, flash SMS shows on the screen automatically regardless of what the recipient is using the phone for at that moment.
Additionally, instead of the message saving automatically on the SIM or phone memory, once it is dismissed from the phone screen, it is gone. The only way the message remains on the phone is if the recipient decides to save it, but it doesn’t happen automatically.
Flash SMS is ideal for all industries, companies, and organizations that want to deliver time-sensitive information needing urgent attention. This might be messages like PIN or OTP. It is also used for advertising purposes where you want to quickly grab the attention of your recipients.
You can see here some of the uses of flash SMS and why it is important.
