Laos has become much easier to travel since the Laos–China railway linked Vientiane, Vang Vieng and Luang Prabang. Coverage in those towns is good; in the mountains, on the Mekong slow boat and in the far north and south, it thins out. Travel data is a little above the global average in price.
Short answer: a 5GB plan covers most one- to two-week trips. For a long stay, a local SIM is usually cheaper.
What a Laos eSIM costs
At the time of writing (October 2026), Wanderly's Laos plans start at $3.99 for 1GB, with 5GB for 7 days around $8. The median across data-only Laos plans is about $1.62 per GB, a little above the $1.43 median across 187 countries in the Wanderly eSIM Price Index. Some larger bundles are short-validity.
eSIM vs a local SIM
Local SIMs from Unitel, Lao Telecom and ETL are cheap and sold in towns with your passport. An eSIM avoids that and works from the moment you land or cross the border.
Coverage where you will actually be
- Vientiane: good 4G.
- Vang Vieng: good in town; patchy in the caves and on river trips.
- Luang Prabang: good in town; limited at Kuang Si Falls and on the Pak Ou caves boat.
- Laos–China railway: coverage at stations; gaps in tunnels, of which there are many.
- Mekong slow boat (Huay Xai–Luang Prabang): long offline stretches.
- Nong Khiaw, the Thakhek Loop and 4,000 Islands: coverage in villages; gaps between.
