| Plan | Price | Network | Speed | After daily allowance | IP breakout |

| Unlimited · 500 MB/day at full speed · Flexible 1–365 days | US$3.99 | Mobitel | 4G | 512 Kbps | UK |

Hotspot and tethering are allowed on every plan we sell. Plans are data-only unless the plan page states otherwise — only selected plans carry calls or SMS. IP breakout is where your traffic exits the network, which is not always the country you are visiting. Prices and networks are read from the same catalogue that powers our machine-readable pricing file, so this table cannot go stale against checkout.
Why an eSIM beats roaming in Sri Lanka
Sri Lanka's mobile market is led by Dialog and state-owned Mobitel, with Hutch and Airtel competing on price. Between them they cover Colombo, Kandy, Galle, Nuwara Eliya, Ella, and most of the coast. Dialog supplies no travel eSIM brand, so a YonoSIM eSIM here rides Mobitel— the same signal a Sri Lankan phone uses — and skips the tourist-SIM registration desk at the airport. The US State Department recommends keeping your itinerary and contacts reachable; a working data line makes that easy.
Install the eSIM on Wi-Fi before you fly, keep your home SIM in the phone with roaming off, and you land at Bandaranaike already connected for tuk-tuk apps, maps, and WhatsApp. Building a wider Asia trip? Compare the sibling guide for India and Thailand.

FAQ
QHow much does a Sri Lanka eSIM cost in 2026?
AA Sri Lanka travel eSIM starts at a few dollars for a few GB and runs to US$20–30 for larger or unlimited plans. That is far cheaper than US carrier roaming, which can run US$10–15 per day, and the eSIM installs before you land at Bandaranaike (Colombo) airport.
QWhich carrier has the best coverage in Sri Lanka?
ADialog has the widest coverage in Sri Lanka, including the hill country and the coast, but it supplies no travel eSIM brand — you can only get it on a local tourist SIM registered at the airport desk. YonoSIM routes on state-owned Mobitel, the next-widest, which reaches Colombo, Kandy, the tea country, and the southern coast.
QWill an eSIM work in the tea country and on the train to Ella?
AMobitel reaches Kandy, Nuwara Eliya, Ella, and most of the southern coast. The scenic hill-country train has patchy tunnels and valleys, so download offline Google Maps for the route before you ride.
QCan I keep my home number in Sri Lanka?
AYes. The Sri Lanka eSIM is data-only, so keep your home SIM in the phone with roaming off. Your regular number still receives calls, texts, and two-factor codes while the eSIM handles cheap local data.
Bottom line
The best Sri Lanka eSIM for 2026 is a Mobitel-backed plan from a few dollars: install on Wi-Fi before you fly, keep your home SIM for your number, and land in Colombo already connected for the hill country and the coast. Compare options on the Sri Lanka destination page and pick the size that fits your trip.
