WiFi-SMS and WiFi-MMS, also known as SMSoIP (SMS over Internet Protocol) and MMSoIP (MMS over Internet Protocol), allow you to send and receive text and multimedia messages over WiFi instead of the mobile network. This enhancement is crucial as we move away from the older 3G network by 28 October 2024.

How to use WiFi-SMS

To use WiFi-SMS, you need:

• A compatible VoLTE/4G Voice smartphone
• Latest software updates installed
• WiFi Calling enabled
• Connected to a compatible WiFi network

Enabling WiFi-SMS

For iPhones:

1. Go to Settings > Mobile > WiFi Calling and turn it on.
2. Go to Settings > Messages, turn iMessage off and back on.

For Android:

1. Open the Phone app and go to Settings.
2. Turn on WiFi Calling.

Benefits of WiFi-SMS

• Send/receive texts over WiFi without mobile signal.
• Avoid SMS charges when travelling and using WiFi.
• Keep messaging after the 3G shutdown in 2024.

Charges

When using WiFi-SMS, you're charged standard rates based on the number, not roaming rates. So even overseas (when using WiFi-SMS only), texts to Australian numbers are charged at local rates.

Please note that while minimal, broadband usage for this service will count towards your data allowance.

Compatible Devices

Most recent smartphones with VoLTE support (required for post 3G-shutdown) should work with WiFi-SMS. Check your device specs for clarification.
