The Singapore & Malaysia eSIM covers 2 countries: Malaysia, Singapore.
A 1-day plan lasts one day from when it first connects. For a longer trip, choose a plan of 7 days or more.
If your eSIM supports top-ups, a Top up button appears in My eSIMs once the eSIM is in use. The extra data goes onto the same eSIM, usually within a few minutes. If it doesn't, buy a new plan; it arrives as a new eSIM.
