Every Top-Up Method, Fully Explained
Step-by-step guidance for all six ways to top up your Singapore prepaid SIM — from official apps to tourist vouchers, with fees, prerequisites, and honest pros & cons.
Official Operator Apps
Prerequisites
- A smartphone (iOS or Android)
- Active SIM card registered to your NRIC/FIN/Passport
- Downloaded app from official App Store / Google Play
- A valid payment method (credit/debit card, PayNow, or GrabPay)
Step-by-Step Guide
Download the Official App
Search for your carrier's app: Singtel (My Singtel), StarHub (My StarHub), M1 (My M1), or TPG (My TPG). Always install from the official App Store or Google Play listing — verify the publisher name matches the carrier.
Log In or Register
New users register using your mobile number and a one-time password (OTP) sent via SMS. Existing customers log in with their credentials. Your account is pre-linked to your prepaid line.
Navigate to Top-Up
In Singtel's app: tap 'Prepaid' → 'Top Up Now'. In My StarHub: tap 'Prepaid' on the home dashboard. In My M1: 'Account' → 'Top Up'. In My TPG: 'Wallet' → 'Add Credit'. Each app clearly labels the top-up flow.
Select Top-Up Amount
Choose from preset amounts ($5, $10, $20, $50) or enter a custom value where supported. Some carriers offer bundle top-ups that include data, SMS, or call minutes alongside credit.
Choose Payment Method
Pay by credit/debit card (Visa, Mastercard), PayNow QR, GrabPay, or Apple/Google Pay depending on your carrier. Credit/debit top-ups are typically instant.
Confirm & Receive
Review the summary screen and tap 'Confirm'. A transaction receipt is sent via SMS and in-app notification. Your balance updates within seconds.
Fees
No additional transaction fees. Credit card surcharges may apply on some carriers (up to 1.5{c6e3cfab1479fd86d77a17c56289fc13820017e9cea77d0574278af01fccd44b}). PayNow and GrabPay top-ups are always fee-free.

- Instant credit update
- Full transaction history in-app
- Bundle top-ups with data add-ons
Cons
- Requires a smartphone and internet connection
- App must match your carrier
- Occasional login issues during peak hours
sinnba-sg Tip: For most Singapore residents, the carrier app + PayNow combo is the fastest and cheapest combo available. Visitors without a local bank account should use the carrier website with an international Visa/Mastercard.
