Bhai, S25 Ultra par calling ke waqt internet band hona VoLTE ya Access Point optimization ka issue hota hai. Ise theek karne ke liye ye steps karein: Settings > Connections > Mobile Networks mein jaakar check karein ki "VoLTE" ON hai ya nahi. Agar ye OFF hoga toh call aate hi 5G/4G cut hokar 3G par chala jata hai aur net band ho jata hai. Settings > General Management > Reset > Reset Network Settings karein. Wi-Fi ke liye: Settings > Connections > Wi-Fi > Advanced Settings (3 dots) > Intelligent Wi-Fi mein jayein aur "Switch to mobile data" ko OFF kar dein taaki network baar-baar switch na ho. ⚠️ Zaroori Note: Agar internet chalne laga ho, toh please reply ke 3 dots (⋮) par click karke "Accept as Solution" mark kar dena. Shukriya
