Depending on your selected Travel Booster plan, the length of your stay while roaming, and your data usage, you may require additional data roaming plans. 
You can keep track of your roaming data usage via the Mobile App, and SMS notifications will be received prior to auto-renewal or upon full consumption of roaming data. 
For 4G mobile service, the auto-renew function is available for Travel Boosters subscribed to the 24-hour and 7-day plans, so you can avoid the hassle of repurchasing additional data roaming plans. 
By default, the 24-hour and 7-day Travel Boosters will be auto-renewed for 4G Mobile services upon the depletion of the bundled roaming data or upon the expiration of the validity period, whichever comes first. 
For 5G mobile services. the 24-hour and 7-day Travel Boosters will automatically renew upon expiration. However, if your bundled data roaming is used up before the validity period ends, you will need to purchase an additional Travel Booster to remain connected.
Should you wish to disable the auto-renew function on the Mobile App, you can manually select from our available Travel Boosters to repurchase the data roaming plan you need, on top of what has already been subscribed to. 
Auto-renew feature will need to be turned off when roaming service is no longer required to avoid the automatic renewal of the Travel Booster upon the return to Singapore.
