Delays usually occur during carrier congestion.
This is caused by poor bandwidth or interference. Try restarting your router or switching to a wired or stable Wi-Fi.
Increase your in-call and system volume levels. If still low, plug in earphones for clearer output.
Premium-rate or short-code destinations are intentionally blocked for fraud prevention. These include voting lines, donation hotlines, and carrier-paid numbers.
Some carriers don’t return confirmation reports for VoIP numbers. You can still verify delivery in the chat log if the status shows “Delivered.”
