A "Flash SMS" or "Class 0 SMS" is a type of text message that appears directly on the recipient's screen without them needing to open it or take any action. It's often used for important or emergency messages because it demands immediate attention. To send a Flash SMS, you typically need to have special software or access to certain features on your phone or through your service provider. The exact method can vary depending on your device and network. Here's a general outline of how it might work: Access Flash SMS Feature: Check if your phone or messaging app supports sending Flash SMS. Some devices and messaging apps have this feature built-in, while others may require additional software or settings adjustment. Compose the Message: Open your messaging app, compose the message you want to send, and select the option to send it as a Flash SMS. Enter Recipient: Enter the recipient's phone number or select it from your contacts. Send: Once you've composed your message and selected the recipient, hit the send button. The message should be delivered almost instantly and will appear directly on the recipient's screen. Recipient's Experience: The recipient will see the Flash SMS pop up on their screen immediately, often with an option to save or dismiss it. It usually doesn't go into their inbox and isn't saved like a regular SMS. Keep in mind that Flash SMS can be perceived as intrusive by some users, so it's essential to use them judiciously and consider the urgency and importance of the message before sending. Additionally, not all phones and networks support Flash SMS, so it may not be available in all cases. https://mishtel.com/flash-sms/
