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?
- 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!
