Important: Given 3G shut down on 28 October 2024, your device must support emergency calling over 4G VoLTE or it will have been blocked from the network. This capability is built into the device hardware - it cannot be enabled through settings if your device doesn't support it.

Device capability
VoLTE support is hardware-dependent. Your device either:

• Has VoLTE capability built-in, or
• Doesn't support VoLTE and needs replacement

Emergency calling requirement
The ability to make emergency calls over 4G VoLTE is:

• A physical hardware feature
• Cannot be added through settings
• Required to continue using the network after shutdown

Network activation
If your device supports VoLTE, it typically activates automatically once enabled at the network tower. Some devices may need:

• Settings adjustments
• Firmware or software updates
• A restart/power cycle

Device settings location

For iPhone:
Settings > Mobile Data > Mobile Data Options > Voice & Data > select 4G, VoLTE On

For Android:
Settings > Network & Internet > Mobile Network > Advanced > VoLTE
(Note: Menu locations may vary by manufacturer)

Compatibility check
To verify your device's VoLTE and emergency calling capability:

• Text '3G' to 3498
• Check manufacturer specifications
• Review device documentation

Remember: If your device doesn't support emergency calling over 4G VoLTE, no amount of settings changes will enable this feature - you'll need to upgrade to a compatible device to continue using after the 3G shutdown.
