VoLTE Call Nahi Lag Rahi? Yeh Setting Check Karein 📞

4G ke full signals hon, internet tez chale, lekin call lagate hi network 2G/3G par gir jaye ya call hi na lage — is ka matlab VoLTE (4G par voice call) on nahi hai. Yeh setting aur network dono ka masla ho sakta hai:

1. VoLTE setting on karein. Settings > SIM ya Mobile Network mein "VoLTE" ya "HD Voice" ka option on karein. Har SIM ke liye alag option hota hai — jis SIM se call karte hain usi ka on karein.

2. Network mode check karein. Settings > Mobile Network > Preferred network type mein "4G/5G auto" select ho. Sirf 2G/3G select ho to VoLTE kaam nahi karega.

3. SIM ko 4G mein upgrade karwayein. Purani SIM (cut ki hui ya bohat purani) VoLTE support nahi karti. Network franchise se free ya sasti 4G SIM nikalwayein.

4. APN setting reset karein. Settings > Mobile Network > Access Point Names mein "Reset to default" dabayein — ghalat APN se data aur call dono mutasir hote hain.

5. Doosre phone mein SIM laga kar test karein. Agar doosre 4G phone mein VoLTE chal jaye to aap ke phone ka software ya hardware masla hai.

6. Kuch phones mein company ki update se VoLTE theek hota hai. Settings > Software Update check karein. Warning: unknown apps se "VoLTE enabler" na install karein — yeh apps data chura sakti hain. Setting sirf official menu se karein.
