Announcement
We're saying goodbye to 3G
Last updated 01 Mar 2024
Farewell 3G! Zero1 is shifting to a fully 4G and 5G network
Singapore’s 3G services will be retired on 31 July 2024 in view of advancements in the mobile communication space where 3G has been largely replaced by 4G and 5G. This is in line with the statement from the Infocomm Media Development Authority (IMDA), which mentioned that the move will allow 5G to “provide a better experience for users and support enterprises undergoing digital transformation”.
After 31 July 2024, if you continue to use a 3G device, you will not be able to make or receive calls, send and receive texts, or use data services. If you use a 4G non-VoLTE device, you will no longer be able to make or receive calls.
Do upgrade to a 4G VoLTE, or 5G phone if you do not have a compatible mobile device.
1. Check if you're using a 3G mobile phone
You will see a 3G or H+ network bar in the top-right corner of your phone screen all the time.
2. Check if your 4G mobile phone supports VoLTE
From your phone’s settings, access ‘Mobile networks’, and look for the VoLTE option. Your device may not support VoLTE if the option does not exist.
You can also check the list of compatible mobile devices or check with your device manufacturer for further verifications.
3. Upgrade to a 4G or 5G mobile phone with Zero1

What's the reason to shut down 3G?
Singapore introduced 3G in 2005 and 4G in the 2012. Since the launch of 5G in 2022, 99% of mobile users in Singapore have adopted 4G or 5G while the number of 3G users continue to drop.
In line with the statement from Infocomm Media Development Authority (IMDA), more bandwidth becomes available for investing in 5G as 3G networks retire, providing a superior experience for users and supporting businesses in their digital transformation journey.
