As phone prices rise these days, at least our telco bills don’t have to. Instead of being tied down to long-term annual contracts, many Singaporeans have shifted to monthly postpaid SIM only plans. From 4G to 5G data, here are some SIM only plans in Singapore you can sign up for, ranked according to affordability.

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.
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.
