Indonesia eSIM FAQs
Does an eSIM work in Indonesia?
Yes — TripSIM eSIMs work across Indonesia on local 4G/5G networks (Telkomsel, Indosat Ooredoo, XL Axiata). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Indonesia eSIM?
Yes. Your physical UK SIM stays active for calls, texts and WhatsApp. The TripSIM eSIM runs alongside it as a data-only line.
Is hotspot / tethering included?
Yes, every TripSIM plan supports personal hotspot.
When should I install the eSIM?
Install before you leave the UK while on WiFi. Activation only starts when you connect to a local network in Indonesia.
Is TripSIM cheaper than UK carrier roaming in Indonesia?
Almost always. UK carriers typically charge £8–£12 per MB in Indonesia. Save up to 90% vs UK roaming.
Does TripSIM work across all Indonesian islands?
Coverage is excellent in Bali, Java, and Lombok. Smaller remote islands may have limited signal.
