How to Block a Number in Singapore
Simple ways to block nuisance calls on iPhone, Android, and through your telco where available.
Last updated: 4 July 2026
Most smartphones let you block a number directly from the recent calls screen. On iPhone, open the recent caller list, tap the info icon, and choose the block option. On Android, the exact path varies, but it is usually available from the recent call details menu.
Blocking is useful for repeat nuisance callers, but it does not stop spoofed caller IDs from appearing under different numbers. That is why number lookup and scam awareness still matter.
If the calls are persistent, check whether your telco offers extra filtering tools and keep records of repeated harassment.
