Wi-Fi & Mobile Data On: How Your Phone Chooses Internet & Switches

• * Phones prioritize Wi-Fi when both Wi-Fi and mobile data are active.
• * Features like "Smart Network Switch" (Android) or "Wi-Fi Assist" (iPhone) can automatically switch to mobile data if Wi-Fi is slow or unstable.
• * Background processes such as app updates or cloud backups may use mobile data even when Wi-Fi is connected, especially if the Wi-Fi signal is unstable.
• * Phones do not use Wi-Fi and mobile data simultaneously; they switch between the two networks.
• * Users can identify the active internet source by observing network icons (e.g., Wi-Fi symbol with arrows or LTE/4G/5G).

Why It Matters: Knowing phone's Wi-Fi/data switching helps manage data and avoid charges.
