Some Prepaid Data Packs, such as Tourist SIMs or selected top-ups, include roaming data for certain countries—like Malaysia, Indonesia, Hong Kong, Macau, and Taiwan. To confirm if your pack includes roaming data, just check your Data Pack details in the M1 Prepaid app.

If your pack doesn’t include roaming data, you can:

1. Buy a Prepaid Roaming Pack using the M1 Prepaid App.
2. Use pay-per-use roaming, which will be charged from your main balance at the prevailing rate for the destination country.

Before you travel, make sure data roaming is switched on in both your device settings and in the M1 Prepaid App.

If you use up all your bundled data, here’s what happens:

Local usage (Singapore)

You’ll be charged $0.07 for every 10KB you use, deducted from your available balance.

For the best value, we recommend purchasing a new Data Pack as soon as possible.

Roaming (overseas)

Charges vary depending on the country you’re visiting and whether you have a roaming pack. If you run out of data or travel to a country not covered by your roaming pack, pay-per-use roaming rates apply—usually $0.03 per KB or the country’s prevailing rate.

To avoid unexpected data charges, buy a Roaming Pack for your destination, or make sure you have enough bundled data before you travel.
