Call Forwarding Missing on iPhone? 6 Reasons

Apple documents call forwarding for GSM service and sends CDMA customers to their carrier, which is why the row is absent on some lines.

Apple files error 1109 under network connectivity. Firewalls, DNS and the router are where the confirmed fixes are, not cables or parts.

If apps die seconds after you switch away, look for Fast App Termination under Developer settings. Two owners fixed it exactly there.

Check the EID on the About screen first, because it splits hardware from software. Older models hold one eSIM, so a filled slot removes the option.

The blocked list moved to Privacy and Security on iOS 26, blocked mail still lands in Trash, and a full block list fails silently.

On a dual SIM iPhone the switch is per line, and the emergency address step gates it. The rest is carrier provisioning, not Apple.

Apple lists four reasons for this message and only one is a counterfeit battery. One of the others is a repair that was never finished.

Find My shows four different messages, not two. One is a seven day expiry, one is a settings change, and one is not a problem at all.

Two permission prompts have to be answered, one on the phone and one on the Mac. After that it is usually a cable that carries power but no data.

The sensors are inside the phone, so it has to be on you. Then check Motion and Fitness permission, and compare Health against Fitness.
