I struggled a long time to get the Simore DualSIM&home 3 working with my Android phone, so maybe this guide will help you. The manual is incomplete and even faulty in some parts.

• Phone: Samsung S10 running Android 12
• App: SIMHome v1.4.4 (from Google Play Store)
• Device: DualSIM@home-3

1. Insert a SIM card into slot 1
2. Power the device and wait 2 minutes
3. Open the app and select “More”, then “Cloud” at the top right corner
4. Create an account and login
5. Accept all permission requests
6. Now tap on “Connection” and “Click to start scanning”
7. A line will show up “SPxxxxxx”, where x indicates the the device ID
8. After selecting the device ID the settings menu opens for that device. It is important to note that the full menu opens only after initial connection, so you must make the correct settings here and now.
9. “Cellular Data” will be enabled, so leave it for now
10. Make sure “WLAN Switch” is enabled, then tap on “WLAN”
11. Tap “Scan” for a WLAN, select your desired WLAN, and enter the password. The app only lets you enter numbers, so go to another app on your phone, for example your browser, and enter the password in the browser url field. Then long tap on the password and select “copy”. Go back to the SIMHome app and long tap into the password field, then select “paste”. The app allows you to paste numbers, symbols and letters.
12. Go back, then select “WLAN” again to verify you are connected to the WLAN. If IP and MAC address are shown then you are connected to your WLAN router.
13. Go back and deselect “Cellular Data”. If you do not deselect this you will not be able to receive calls.
14. Now (still in the “More” view) tap “Binding” at the very bottom of the screen to bind the phone to the device

If all went well you will now be able to make and receive calls. Note that the Settings menu as explained before will not be visible anymore after binding. If you made a mistake or need to start over for another reason, do the following:

1. Reset the device by inserting a pin into the reset hole and keep it pressed for 10 seconds (the device must be switched on)
2. In your phone, go to Settings –> Apps and find the SIMHome app, then delete cache and data
