When you exceed the data volume for the SuperRoam Asia or SuperRoam Global pack that you purchased, you will be charged pay-per-use data rates for the country that you are currently roaming at.
To avoid incurring pay-per-use data rates, simply purchase other Roaming Add Ons such as GoRoam APAC Plus before you use up your data!
*IMPORTANT advisory*: For users using GoRoam APAC Plus in the USA, please note that the data may only be used in US Mainland, and is NOT applicable in US territories, e.g. Guam.
