A. Monitor your data usage closely during the first month to establish a baseline for performance. After the initial month, if you notice a drop in performance, try resetting your network settings. On most devices, you can do this by going to Settings > General Management > Reset > Reset Network Settings. This can help clear any temporary issues affecting your connection.
B. Consider switching to a different network band if your device supports it. Some devices allow you to select between 3G, 4G, or 5G networks. Go to Settings > Network & Internet > Mobile Network > Preferred Network Type and select a different option to see if performance improves.
