In most cases, call issues are due to the network coverage in the location you are in.
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.
To fix this issue, follow the steps below:
- Check the network coverage on the Razer Phone.
Note: Network signal is affected by walls, buildings, trees, and weather conditions.
- Make sure that “LTE (recommended)” is selected. Navigate to Settings > Network & internet > Mobile network, expand “Advanced” and select “Preferred network type”.
Note: If you are in a poor 4G coverage area, you can force your phone to use lower frequencies like 2G and 3G. This may or may not improve performance depending on the network coverage.
- If you are still experiencing the issue, there might be a problem with your SIM card and may have to contact your network provider to request a replacement.
- If the issue persists, back up the data and perform a factory reset.
