If you have poor 3g/4g mobile network coverage in say your office – it makes sense to use WiFi calling for an uninterrupted calling experience. But how do you force your phone to use WiFi and not try and use the mobile network?

On Android:

  • Phone Settings – Call Settings – make sure WiFi calling is enabled.
  • Put phone into Airplane Mode (this will turn Wifi off)
  • Turn Wifi back on

Then just remember to turn airplane mode off before you leave the office!
