why are calls dropping or failing ?

Call drops or poor voice quality usually happen due to signal strength, network congestion, or VoLTE-related coverage in your area. In many cases, it improves with a small change in settings or location.

Typical causes

Indoor low-signal zones (basements, lifts, thick walls)

Congestion during peak hours

Weak VoLTE coverage in that area

SIM activation still pending

Device network mode mismatch (e.g., forcing 5G/3G instead of Auto/LTE)

Quick fixes

Move to an open area or near a window

Enable VoLTE in network settings

Restart your phone and wait for full activation

Keep network mode on Auto / LTE (recommended)

Switching location or enabling VoLTE usually resolves most call quality issues.
