What is Singtel Asia roaming?
Roaming allows you to use your mobile phone overseas while keeping your Singapore number active. Instead of swapping SIM cards or buying a local number, a Singtel Asia roaming plan lets you stay connected to data across supported destinations.
Singtel offers both postpaid and prepaid mobile plans, and some already include Asia or worldwide roaming benefits. However, the data allowance or duration is often fixed and may not fit every trip. For more flexibility, you can purchase an add-on Singtel Asia roaming plan.
