eSIM for Kampong Thom
Kampong Thom is a central Cambodian town on the main road between Phnom Penh and Siem Reap, best known as the base for the pre-Angkorian temples of Sambor Prei Kuk, a UNESCO World Heritage site of brick towers in the forest. It is mostly a convenient stopover. Coverage in the town is solid on Smart and Metfone, thinning across the rural roads to the temples and the countryside beyond.
An eSIM Cambodia gives you access to the same plans in Kampong Thom as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 20 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Kampong Thom
Kampong Thom sits on the well-covered National Road 6 between Phnom Penh and Siem Reap, an easy and connected stop. With an eSIM active you can navigate the town and arrange the trip out to Sambor Prei Kuk. The town is your connectivity base; the pre-Angkorian temple complex around 30 km away and the rural roads to it have thinner signal, so having data live helps coordinate the visit before you head into the countryside.

Coverage in Kampong Thom
Kampong Thom has dependable coverage across its core. The town along National Road 6, with its market, guesthouses and the riverside, carries solid 4G on Smart and Metfone, with Smart the steadier in-town pick. The highway through town is well covered, keeping you connected on the Phnom Penh to Siem Reap drive. Coverage thins on the rural road out to Sambor Prei Kuk, the forest temple complex, where the brick towers sit among trees with patchy signal, and across the surrounding farmland. Metfone reaches furthest into the rural areas. The central highway location keeps the town well connected, with the temple road the main soft spot. For the through-travellers who make up most of Kampong Thom's visitors, this is ideal: the town and the highway stay reliably online for planning the next leg, and the only thinner stretch is the rural run out to the forest temples of Sambor Prei Kuk, an easy place to be briefly off-grid among the brick towers.

How much data in Kampong Thom
A stop in Kampong Thom runs a modest 2 to 4 GB across navigation, the temple trip and photos, since it is mainly a stopover. The town and highway are well covered so data flows freely. The Sambor Prei Kuk trip is limited by coverage rather than data, so prepare offline before heading out.
