The calculation of $100 Data Roaming Cap will consider all data roaming usage. Subscription to the Data Passport will just enable the data roaming usage to be deducted from your local data bundle. To continue data roaming usage in your selected Data Passport destination, you can de-activate $100 Data Roaming Cap by calling *123# from the relevant mobile line.
You can re-activate $100 Data Roaming Cap upon anytime via My M1 App or call *123#.
