Huawei Ascend 5W Can't Call over WiFi


  • Huawei Ascend 5W is connected to WiFi but sees an error "Connect to WiFi" to allow calls


  • Huawei Ascend 5W
  • Outbound WiFi calls
  • Poor or no GSM coverage 


Use Marshmallow Dialer- Android 6 as the default calling application


This is due to poor or no GSM cellular connectivity with the phone. The phone will still try to register a cellular connection to initiate a WiFi call when using the default calling application.

Additional Notes

  • Using the phone in airplane mode with WiFi enabled will not fix this issue and will cause the same symptoms
