If you are experiencing this problem when using a third-party application, report this problem to Customer Support. This problem could be due to an app currently unsupported by the Razer Phone 2.

Note: Before proceeding to the troubleshooting steps, be sure that the Razer Phone is up to date. Navigate to Settings > System > Advanced > System update > Check for update.

If it is a normal voice call using the built-in phone app, follow the steps below:

  1. Disable Wi-Fi calling.
  2. Select a different “Preferred Network” by going to Settings > Network & Internet > Advanced.

  3. Tap “Preferred Network Type”.

  4. Switch between “LTE (recommended)”, “3G Only”, and “2G Only” and verify if the issue persists each time you switch the network type.

  5. Move to a different location, preferably to a location with a stronger signal.
  6. Try inserting the SIM card to a different phone to verify that the SIM is not defective. If the issue persists, this could be caused by a defective SIM card. In that case, contact your network or service provider.
  7. If the SIM card works on a different mobile phone, test a SIM from a different mobile carrier and verify if the issue has been resolved.
  8. If the above steps did not fix the issue, contact Customer Support to assist you further in troubleshooting this issue.
