If the phone has signal but still cannot call, it may be due to signal blockage, building interference, or an enabled call‑restriction feature; disabling the restriction or checking the SIM card can resolve the issue.
SIM card operation can be affected by the phone’s status, charging condition, feature usage, temperature, and other environmental factors.
Low or missing audio may occur if the phone’s internal components are not properly seated or if the device has been exposed to conditions that affect its speaker performance.
