Related QNAs

The call volume is too low.

Increase your in-call and system volume levels. If still low, plug in earphones for clearer output.

I’m not receiving OTPs on my virtual number.

Some banks or websites restrict OTP delivery to VoIP numbers. If possible, use an alternate number or contact the provider for manual verification.

I’m not getting verification codes.

Some services block codes to VoIP numbers. Confirm your number supports SMS or try receiving via a different channel.

I hear ‘Number Not Reachable’.

The destination network might block VoIP connections. Try calling another line or contact the recipient via a different method.

What are your feelings
