Smsinbox: SMS & MMS messages

Istcom Inform

About this app

Smsinbox is an SMS and MMS app with a modern Material 3 design. No ads and no paid features: everything is available right after installation.

MESSAGING
• All your conversations in one list, with search across messages and contacts.
• Delivery reports: a check mark in the chat shows that your message was delivered.
• MMS support: photos and pictures right in the conversation.
• Dual SIM: see which SIM a message came to and choose the SIM for sending.
• Quick reply in a pop-up window — no need to open the app.
• Pin important conversations to the top and keep messages in Favorites.

LOOK AND FEEL
• Light theme and the “Moon” dark theme.
• Seasonal and holiday themes — Autumn, Cats, Spring, Halloween, Christmas and more — each with its own backgrounds, message bubbles and icons.
• Adjustable font size and message bubble style.

PRIVACY AND ORDER
• Private folder: keep personal conversations away from prying eyes. Unlock it with a PIN or a secret touch.
• Blocklist: messages from unwanted senders no longer distract you.
• Trash: restore an accidentally deleted message; the trash is emptied on a schedule.

HANDY TOOLS
• Scheduled messages: write birthday wishes in advance and the SMS will be sent right on time.
• Cloud backup of SMS and contacts linked to your Google account, and restore on a new phone.

To send and receive messages, set Smsinbox as your default SMS app — Android requires this.
