Part 1. Why Is Call Forwarding Not Working on My iPhone?

The iPhone's call forwarding feature relies on the carrier's network, not just the iPhone settings. If your call forwarding keeps loading and not working, there could be several reasons. Identifying the underlying cause is essential for finding the right solution. Here are several common factors that cause the call forwarding not to work on your iPhone.

Network Connection Issues

A poor network connection can interfere with call forwarding. If your iPhone's network is weak or inconsistent, it may prevent the call forwarding feature from functioning correctly.

Carrier-Related Problems

Some carriers impose restrictions on call forwarding, especially when it involves international calls. Also, carriers can have compatibility issues with certain iPhone models.

Software Glitches or Updates

An outdated iOS version or software bugs can also affect call forwarding. After a major update, some users may find their call settings reset or malfunctioning.

Incorrect Call Forwarding Settings

Sometimes, call forwarding might be accidentally disabled or misconfigured, resulting in an inability to forward calls. The settings are correctly configured is key to maintaining this feature.

Part 3. How to Fix iPhone Call Forwarding Not Working

Method 1. Disable and Enable Call Forwarding

Sometimes the settings don't work correctly, so you can turn off Call Forwarding, wait a few seconds, and then turn it back on and enter the number. This allows the system to resend activation instructions to the operator, which can resolve temporary lags or setting exceptions.

Step 1. Go to iPhone Settings > Apps > Phone.

Step 2. Find Call Forwarding and tap one phone number, and turn off the Call Forwarding.

Step 3. Keep off for a while, and then re-enable it and set the forward phone number.

Method 2. Disable VPN Connection

A VPN can alter your network routing and may interfere with the carrier connection, potentially causing call forwarding to fail. To ensure that call forwarding functions correctly, make sure to disable your VPN connection.

Step 1. Open Settings and tap VPN.

Step 2. Disconnect the VPN Status.

Method 3. Switch Network Connection

When you have set up the call forwarding on your iPhone, you need to stay in a cellular network connection area to make it work. It's suggested that you turn off the Wi-Fi and turn on Cellular.

Step 1. Access iPhone Settings.

Step 2. Tap WLAN to disconnect the Wi-Fi connection.

Step 3. Back and tap Cellular > Cellular Data to enable mobile data use.

Method 4. Disable Live Voicemail

If you have enabled Live Voicemail for your Phone app, it may conflict with the Call Forwarding. The call may be forwarded to the Voicemail instead of the target forward number. You should disable Live Voicemail to avoid the conflicts.

Step 1. Go to iPhone Settings > Apps > Phone.

Step 2. Find Live Voicemail and disable it.

Method 5. Turn Off LTE

LTE allows for faster data transfer, so users generally leave it on. But when LTE is in a bad state, call forwarding will be affected, causing it to malfunction. Temporarily turning LTE off can fix it.

Step 1. Open Settings > Cellular > Cellular Data Options.

Step 2. Choose Voice & Data and turn LET off.

Method 6. Remove and Reinsert SIM Card

Abnormal contact between the SIM card and the device can also cause call forwarding to fail. You can turn off your iPhone, remove the SIM card, clean the SIM card with a paper towel, and plug it back into your iPhone.
