Ensure 100% Visibility – Messages Pop Up Instantly Without Being Saved
What is Flash SMS?
Flash SMS, also known as Class 0 SMS, is a special type of message that bypasses the inbox and pops up instantly on the user’s screen. It’s not stored by default, which makes it ideal for sensitive, time-critical communication.
Think of it as your direct line to attention — no delays, no distractions.

Yes, Flash SMS can be sent internationally, but delivery success may depend on the recipient’s mobile network and device compatibility. PRP Services Pvt. Ltd. offers region-specific solutions to ensure your message reaches screens around the globe.
Most GSM mobile phones support Flash SMS, especially older models and basic feature phones. However, the display experience may vary slightly depending on the phone’s operating system or brand.
Flash SMS is typically one-way communication. It’s designed for immediate attention, not for conversations. If you need replies, you can include a call-to-action or a link in your message directing users to respond via another channel.
Flash SMS is generally priced slightly higher than regular SMS due to its premium delivery mechanism and guaranteed visibility. PRP Services offers transparent pricing plans that scale with your needs — from startups to enterprises.
