How do I update my iPhone carrier settings?

Carrier settings are files that contain Optimum Mobile network settings such as network frequencies, cell towers, and settings for calling, data, messaging, and voicemail.  You may receive notifications on your iPhone from time to time to update the Optimum Mobile carrier settings.  Having the most up-to-date Carrier settings is recommended for optimized device functionality.

When a Carrier Settings update is available, you will be prompted to install it.  If Optimum Mobile releases a mandatory update, you will see an OK button instead of an Update button to let you know that the update was downloaded and installed.

To manually check for and install updated Carrier Settings:

  1. Make sure the iPhone is connected via LTE or WiFi
  2. Tap Settings > General > About and scroll down to Carrier.  If an update is available, you will see an option to update the Carrier Settings

To see the current version of Carrier Settings on your iPhone:

  1. Tap Settings > General > About and look next to Carrier. To see additional carrier information, tap the version number
