📶 Stay Connected Seamlessly with VIVIFI!
As the digital landscape evolves, so does your connectivity. With the imminent shutdown of Singapore 3G networks, it's crucial to ensure your device is prepared for the transition to 4G and 5G technology.
After 31 July 2024, you will not be able to use a 3G mobile phone with your existing VIVIFI SIM card/e-SIM.
If you use a 4G non-VoLTE mobile phone, you will not be able to make or receive mobile calls.
VIVIFI is Ready
No need to change SIM Card / e-SIM
Your existing VIVIFI SIM cards / e-SIM are 4G/5G enabled.
4G/LTE Voice call
VoLTE* will be enabled automatically upon 3G shutdown.
What do you need to do?
#1
Check if your mobile phone is in the recommended mobile phone list. If so, you are good to go.
Otherwise, please help to work on #2 and #3.
#2
You see a 3G or H+ network bar in the top-right corner of your mobile phone screen all the time.

It is important for VIVIFI to have you connected.
