A Slashtel eSIM is data only and has no phone number. The home SIM stays in the phone for calls, texts and bank codes while the eSIM carries mobile data. Install it by QR code before the trip and switch it on when you land; it connects to local networks automatically. Travellers heading to a destination covered by both a Singtel or StarHub pack and an eSIM should check the table on this page for the trips where the eSIM costs less.
