Contact your Carrier (Cellular Service Provider) The agency who issued the SIM to you and get to know if they have this call forwarding feature on their network. If yes...
Set up call forwarding or call waiting (GSM)
- Go to SettingsÂ
 > Phone. - Tap any of the following:
- Call Forwarding:Â
 appears in the status bar when call forwarding is on. You must be in range of the cellular network when you set iPhone to forward calls, or calls won’t be forwarded.- On models with Dual SIM, choose a line.
- Call Waiting: If you’re on a call and call waiting is turned off, incoming calls go directly to voicemail.
- On models with Dual SIM, call waiting works only for incoming calls on the same line, unless the other line has Wi-Fi calling enabled and a data connection is available. See Set up cellular service on iPhone.
For CDMA accounts, contact your carrier for information about enabling and using these features.
For information about conditional call forwarding (if available from your carrier) when the line is busy or not in service, contact your carrier for setup information.
