Featured Guide
How to Top Up Your Prepaid Mobile in Singapore
Singapore has one of the most flexible prepaid top-up ecosystems in Southeast Asia. Whether you prefer doing it from your sofa or on the go, there's a method that works for you. Here's a clear, step-by-step breakdown of every major channel available today.
Top-up credits within minutes
For all digital methods, balance usually reflects in under 5 minutes. Physical top-up cards may take slightly longer depending on the operator's system.
01
Online Portal
Fastest OptionLog in to your carrier's official website — Singtel, StarHub, M1, or GOMO — and navigate to the top-up section. Enter your mobile number, select an amount, and pay securely via PayNow, card, or eNETS. Funds are typically credited within minutes.
02
AXS Machines
Widest CoverageOver 800 AXS kiosks are spread across Singapore's MRT stations, shopping malls, and community centres. Select "Mobile Top-Up", choose your operator, key in your number, and pay with NETS, credit card, or cash. A printed receipt confirms the transaction.
03
7-Eleven & Cheers
No Internet NeededPick up a prepaid top-up card or request a stored-value reload at any 7-Eleven or Cheers counter — both chains have hundreds of outlets islandwide. Simply tell the cashier your operator and top-up amount, pay in cash or via NETS, and scratch to reveal your PIN.
04
In-App Top-Up
Bonus Data DealsAll major Singapore operators offer dedicated mobile apps — MySingtel, My StarHub, My M1, and GOMO — available on both iOS and Android. Open the app, tap "Top Up", link your PayNow or credit card, and reload instantly. App-exclusive promotions often give bonus data.

Operator Review
StarHub
4/5
StarHub's refreshed prepaid lineup and expanded 5G footprint make it a compelling mid-market pick in 2025, especially for households already bundled into its broadband and cable TV ecosystem.
Operator Review
M1 (Keppel)
3/5
M1 offers competitive data rates and a digitally-forward approach that appeals to younger subscribers, but inconsistent rural and outdoor coverage holds it back from the top tier in our 2025 ranking.
