# Why Do Calls Drop When I Switch to Another Tab on Mobile in FreJun? | WebRTC Throttling FAQ

## On mobile, calls in FreJun can drop when switching to another browser tab because mobile browsers often throttle or pause background tabs, which interrupts the WebRTC connection used for calling. To prevent call drops, it is recommended to keep the FreJun tab in the foreground and avoid switching to other tabs while an active call is in progress.

Mobile browsers often throttle or pause background tabs, which can disrupt WebRTC. Try to keep the tab in the foreground during active calls.
