I am running a dual SIM setup on my physical SIM (Zong) and eSIM (Ufone). Ever since configuring the profiles, my eSIM randomly drops to "No Service" multiple times a day until I switch Airplane mode on and off. Is this a network carrier issue or an APN configuration error?

This is a common network handoff issue across local towers in Pakistan. Follow this structured network adjustment process to lock down your cellular stability: 1. Reset Network Configurations: Navigate to Settings -> General -> Transfer or Reset -> Reset -> Reset Network Settings. (Note: This clears saved Wi-Fi keys, so keep them handy). 2. Manually Select LTE Carrier bands: Go to Settings -> Cellular -> Select your eSIM line -> Network Selection. Turn off "Automatic" and select your specific provider explicitly from the manual scan menu list. 3. Turn Off VoLTE: If you are in an area with erratic 4G node distribution, navigate to Cellular Data Options -> Voice & Data, and shift down to LTE or disable VoLTE toggles. This prevents your active profile from crashing when trying to authenticate HD voice paths.
