Blur your phone number bro. And it seems like a software bug you have selected correct option.

🔍 Common Causes

1. Default SIM settings not applied correctly


2. Messaging app ignoring SIM selection


3. Carrier-specific restrictions


4. Device software glitch or outdated firmware

✅ Try These Solutions

🔧 1. Check Default SIM Settings

Go to Settings > Network & Internet > SIM cards (may be called "SIM management" or "Dual SIM settings")

Set:

Default for SMS → Always ask or SIM2

Alternatively, make sure SIM2 is selected as the default.



> ⚠️ Some phones ignore manual selection if a default is set. “Always ask” is usually the safest.




---

💬 2. Use the System Messaging App

Make sure you're using the default SMS app that came with your phone or Google Messages.

If using a third-party SMS app, it may not support proper dual-SIM functionality.


✅ Set SIM per message (if supported)

Open the Messages app

Tap the SIM switcher icon above the keyboard or next to the “Send” button

Select SIM2 before sending


> If the icon is missing or switching doesn’t work, try another messaging app (like Google Messages).




---

🔄 3. Clear Messaging App Data & Cache

Go to Settings > Apps > Messages (or your default SMS app)

Tap Storage > Clear cache and data

Restart your phone and try again



---

📶 4. Check SIM Signal and Carrier Settings

Make sure SIM2 has active signal and SMS plan

Try swapping SIMs (put SIM2 in SIM1 slot and vice versa) to check if it’s a slot issue

If SIM2 is from a different carrier, there could be compatibility issues

🆕 5. Update Your Phone

Go to Settings > System > Software update

Install any pending updates — dual-SIM SMS issues have been fixed in recent updates on some brands (like Xiaomi, Samsung, Realme)
