All 4 carriers on this page run their own network. Each one has its own APN, so make sure you copy the settings for the carrier named on your SIM, not the one with the best coverage.
Singtel is the only carrier here that uses a username and password in the APN. For the others, leave both fields empty: a username where none is needed can stop data from working.
None of the carriers here list separate MMS settings. Picture messages usually work with the internet APN, or the phone sets them up itself.
The carriers here use the mobile country code 525, the first three digits of every network code in Singapore. Android usually fills in the MCC and MNC from the SIM, so you rarely need to type them.
Visiting Singapore with your own SIM? Keep your home APN: roaming data still goes through your home carrier. You only need these settings with a local SIM bought in Singapore. Or skip the SIM shop with a Singapore eSIM, which sets its own APN.
iPhone
No Mobile Data Network option? Your carrier locks it, and the iPhone sets the APN for you.
Android
Made a mess of it? Reset to default in the same menu brings the original settings back.
Data and roaming on
Mobile data must be on, and airplane mode off. On a local SIM, data roaming can stay off.
The APN, letter for letter
For Singtel that is e-ideas. One wrong dot or capital is enough to block data.
Username only if listed
Only Singtel needs one here. Leave it blank for the rest.
Select it and restart
On Android, tap the entry so its dot is filled. Then restart the phone and open a website.
Calls and texts work, only data does not? That points to the APN, because calls and normal texts do not depend on it. If nothing works at all, the SIM itself may not be active yet: ask the shop or the carrier.

The Singtel internet APN is e-ideas, with username 65ideas and password 65ideas.
The StarHub internet APN is shwap, with the username and password left blank.
The M1 internet APN is sunsurf, with the username and password left blank.
The SIMBA internet APN is TPG, with the username and password left blank.
Singtel uses a username and password in the APN. For the others, leave both fields blank.
Usually not. Your phone reads the APN from the SIM and sets it for you. You only need to add it by hand if mobile data does not work, often after moving a phone between networks or on an unlocked import.
Not if you use your own SIM: roaming uses your home carrier's APN. You only need the settings on this page if you buy a local SIM from a carrier in Singapore.
No. At worst, mobile data or picture messages stop working until you fix it. On Android, Reset to default in the APN menu puts the carrier's own settings back.
A travel eSIM installs before you fly and usually sets its own APN. Pay in crypto, no ID, no email.
