I've got an issue with my new phone that I hope someone can provide some assistance. When attempting to make a phone call it ends immediately after pressing the green connect button. Any help will be greatly appreciated.
Most likely because there is no service or reliable connection. If using Wi-Fi calling, disable it, put phone in airplane mode then take it off airplane. Ensure your mobile network settings indicate phone is registered with the provider. If call doesn't work, make sure SIM is program correctly by putting it in another phone and try making the same call.
