1. Dial *123# to activate Data Passport when you are overseas and have no access to mobile data connection. There are no roaming charges for using *123#.
  2. If you are subscribed to $100 Data Roaming Cap (DRC), the calculation of $100 usage will consider all data roaming usage (excluding usage covered by Data Passport). Data Roaming service will be terminated once your usage reaches the cap of $100. To continue using data roaming overseas, you can reset the DRC counter via My M1 App.
  3. If you are subscribed to Data Roaming Alert and Data Passport, you will still receive notification SMS when data roaming usage exceeds $50, $100 and $200 as the calculation of Data Roaming Alert will consider all data roaming usage.
  4. It is good practice to re-start your device to refresh network settings if you have activated or de-activated any roaming services e.g. Network Lock, Data Roaming Cap and Data Roaming Alert.
