Once you have enabled Wi-Fi calling on your smartphone, it will automatically kick in when your cellular service is poor or unavailable. However, when you move out of the Wi-Fi coverage area, calls and texts will switch back to the cellular network. All this happens smoothly, and you shouldn't experience any dropped calls or other issues due to the switch taking place.
Wi-Fi Calling can also be beneficial if you live or work in an area with poor outdoor or indoor cellular service but have a Wi-Fi connection. Additionally, this feature doesn't consume high amounts of data, a typical voice call is around 1MB per minute, so you don't have to worry about data charges.
There are no extra charges to customers as this is a free-to-use feature as part of your SIM service. If you are making a call or texting over Wi-Fi, it will contribute as normal to your allocated minutes and texts per month as cellular use would.
No, as long as you have one of our triformat SIMs which are 4G and 5G enabled you can use this feature on any compatible smartphone.
