How do I send messages?

If you've ever wondered how to send a text message or how to know if your message was delivered, this guide offers clear explanations with visuals. You’ll learn how to recognise message status indicators (like what one or two blue ticks mean on WhatsApp), how to reply directly in a group chat, and how to manage your conversations without feeling overwhelmed.
