Caller Unknown vs Private Number

Sometimes when you receive a call, the number appears as Private or Unknown. Here's what those terms mean:

• Private Number - your caller is hiding their number on purpose. There may be many reasons for this, including privacy concerns or malicious intent.
• Unknown Caller - there is an error in the network settings or a feature, which is not supported, is enabled.

If your number shows as Private to others:

1. Open the Phone app.
2. Tap on the three dot menu on top right → Settings → Calling accounts.
3. Select the SIM card you wish to configure → Additional settings. Wait for the page to load.
4. Tap on Caller ID and select the option you prefer.

If your caller Is "Unknown"

As a first step towards solving this situation, make sure to update to the latest software version.

In case the update did not help and it happens with different callers, there are a couple of things to try:

Disable VoLTE (Enhanced 4G LTE, 4G Calling)

The exact name of the feature varies across networks.

1. Go to Settings → Network & internet → Mobile network → Advanced.
   • In Android 13, go to Settings → Network & internet → SIMs. Select the SIM you want to configure and scroll down.
2. Tap on VoLTE to disable it.

If you can't find the option in your Fairphone, change the Preferred network type to 2G/3G auto. This will disable VoLTE by default.

Disable Wi-Fi calling (VoWi-Fi, Voice over Wi-Fi)

Additionally, if the issue is still not solved, you might also need to disable Wi-Fi calling.

1. Go to Settings → Network & internet → Mobile network → Advanced.
   • In Android 13, go to Settings → Network & internet → SIMs. Select the SIM you want to configure and scroll down.
2. Tap on Wi-Fi calling and disable it.

If you can't find the option in your Fairphone, disconnect from the Wi-Fi and see if this helps. If this solves the issue, contact our Customer Support.
