You are advised to have the required amount of credit in your account based on the country you intend to visit before travelling.
For example, if you do not have RM10 credit in your main credit balance account when you travel to countries where the U Data Roam 10 is available, the promotion will not apply to you. You will not be able to subscribe to U Data Roam if you have insufficient credit in your main credit balance account. This is because U Data Roam charges can only be deducted from the Main Credit Balance even though you have sufficient credit in your CreditShare Balance.
If you have less than RM36 in your account when you travel to countries where the U Data Roam 36 is applicable, you are still allowed to perform data roaming until the service is blocked for insufficient credit. Data usage will be charged at RM9/MB and capped at RM36/day.
