How to activate Singtel roaming in Indonesia?
Activating your Singtel roaming plan for Indonesia is striaghtforward. Follow these steps:
- Confirm your plan: Check if your existing Singtel plan includes roaming in Indonesia, or if you’ll need to purchase a roaming add-on (either a postpaid or prepaid roaming add-on)
- Purchase the add-on (if needed): For postpaid users, you can buy all the roaming plans through the My Singtel app. Some plans are available via Singtel website chatbot or phone call. Prepaid users can purchase roaming packs directly through the hi!App
- Turn on roaming before departure: Make sure data roaming is enabled in your phone settings so the connection activates once you land in Indonesia.
- Connect to a partner network: Upon arrival in Indonesia, your phone should automatically connect to one of Singtel’s roaming partners. If not, select the network manually under your phone’s mobile network settings.
- Track your usage: Use the My Singtel app or hi!App to monitor data usage and validity, especially if your plan has a set allowance. This helps you avoid unexpected charges.
