If you’re unable to make a call from your Galaxy device, it may be due to a faulty SIM card, an issue with your account or carrier, or a device setting. Check the guide below to find a solution.

Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps:

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions.

You may experience call issues if you’re in an area with poor cell reception or if there is an issue with your account or carrier.
  • If you have poor cell reception, there will be a few to no network bars on the upper right corner of your screen. If that’s the case, move to a spot with stronger signal.
