With more people relying on streaming, video calls, and cloud-based apps, stable internet is essential. However, as mobile data costs remain high and unlimited plans often have hidden limits, features like Smart Network Switch can quickly eat into your data allowance. That’s why learning how to disable this setting in 2025 is more relevant than ever for Samsung users.
