Flash SMS is a distinct kind of text message that appears instantly on the screen of a mobile device without requiring the user to take any action in order to read it. Even if the screen is locked, a flash SMS, also referred to as a class 0 SMS, will display on the smartphone. SMS is rarely used by most users, with the exception of OTPs and transactional messages. Companies started sending unnecessary advertising flash messages to promote offers because people weren't checking their SMS inboxes. Fortunately, there is a quick fix to permanently stop flashing messages on any Android device.
There are various ways to stop this service across various telecom networks. The steps for Airtel, Vodafone Idea, Jio, and BSNL are listed below. If you want to stop receiving flash messages, you can select the network you're on.
