Sri Lanka eSIM FAQs
Does an eSIM work in Sri Lanka?
Yes — TripSIM eSIMs work across Sri Lanka on local 4G/5G networks (Dialog Axiata, Mobitel, Airtel LK). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Sri Lanka 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 Sri Lanka.
Is TripSIM cheaper than UK carrier roaming in Sri Lanka?
Almost always. UK carriers typically charge £8–£12 per MB in Sri Lanka. Save up to 90% vs UK roaming.
Does TripSIM work on Sri Lanka trains?
Coverage on popular routes like Colombo-Kandy and Kandy-Ella is generally good, with some drops in mountainous sections.
