This issue occurs because both SIMs share network resources, affecting signal stability and bandwidth. Here’s why your internet connection improves when one SIM is disabled:

📶 Network Prioritization – When both SIMs are active, your phone constantly switches between networks, leading to unstable connections.
🔄 Dual SIM Standby Limitation – Most phones, including Samsung, use Dual SIM Dual Standby (DSDS), meaning only one SIM can actively use data at a time, causing delays in switching.
📡 Network Interference – If both SIMs are from different carriers, they may use different frequency bands, leading to signal conflicts.
⚡ Power Consumption & Throttling – Running two SIMs increases battery usage, causing performance drops that affect network stability.

🔧 Possible Solutions:

✔️ Use one SIM for calls & SMS, and the other for mobile data (Settings → SIM Manager).
✔️ Try locking your data SIM to a specific network mode (e.g., 5G/4G).
✔️ If possible, switch to a single high-speed SIM for better stability.
