The common reasons why calls keep failing include:
- Weak or poor cellular signal strength or network coverage in your area.
- Network congestion during peak usage times, leading to dropped calls.
- Carrier outages, maintenance, or disruptions affecting call connectivity.
- Device issues such as outdated operating system software, software bugs, or corrupted network settings.
- SIM card problems, including improperly inserted, damaged, or deactivated SIM cards.
- Account-related issues like unpaid bills or service suspensions.
- Phone settings such as airplane mode being enabled, call barring, or blocked numbers.
- For internet calls (VoIP), unstable or weak Wi-Fi connections and provider server issues.
To fix call failures, you can try checking your signal strength, restarting the phone, updating the phone software, verifying the SIM card is correctly inserted, ensuring your account is active and paid, and checking phone call settings like airplane mode or call blocking. Moving to a location with better coverage or switching to Wi-Fi calling can also help.
