Answers to common questions.
Why does Smsinbox need to be the default SMS app?
Android lets only the default SMS app send, receive and store messages. You can switch back at any time in system settings.
How do I choose which SIM to send from?
Tap the SIM selector next to the input field in the chat. Incoming messages show which SIM they came to.
What does the cloud backup include?
SMS and contacts, linked to your Google account. MMS are not included. The previous copy is kept until the new one is fully saved.
How do I restore on a new phone?
Install Smsinbox, set it as default, open Settings → Backup, sign in with the same Google account and tap Restore.
Will a scheduled SMS go out after a restart?
Yes. Scheduled messages survive a restart. For exact timing, allow alarms and reminders when the app asks.
Why don’t I see some themes?
The catalog depends on your region. Change it in Settings → Account → Region.
Can each SIM have its own sound?
Yes. Set a notification sound for each SIM in Settings → Notifications.
Why did a warning appear before opening a link?
The sender isn’t in your contacts or the link looks risky. Check the domain shown in the dialog; “Cancel” is the safe default.
Where is the “Copy code” button?
In the notification of an SMS that contains a one-time code. It’s hidden in private notification mode.
