What’s a SIM-only plan?

SIM only plans are mobile service plans that provide a SIM card or an eSIM with data, talk time, short message service (SMS), and sometimes international roaming to countries such as Malaysia and Thailand. Since you’re paying month by month, it’s easier and more convenient if you want to switch to a different plan or a new telco.

4G vs 5G SIM-only plans
Many SIM-only plans offer both 4G and 5G data. To put it simply: 5G is faster than 4G.
5G means faster loading times when scrolling through social media and better connectivity when you’re in an MRT tunnel, even during peak hour on the City Hall-Raffles Place stretch. While the difference may not be noticeable to the average person, avid mobile phone gamers will definitely appreciate the speed boost. 5G is, however, more expensive compared to 4G.
Do note that your phone needs to be 5G compatible if you’re considering switching to 5G.
Switch to an affordable SIM-only plan in SG
SIM-only plans are low-commitment, making it easy to hop between telcos and try something new, so there’s no need to stick with just one permanently. While you may choose to stick to well-known and reliable, but pricier telcos, you won’t know if these are good until you give them a chance.
