    Check device compatibility →
  2. 02

    Install within 24 hours before departure

    Usually install within 24 hours before departure over stable Wi-Fi. Once delivered, use quick installation, a QR code or manual details from your order or “My eSIMs”. Billing starts according to the selected plan.

  3. 03

    Set your data line and activate as instructed

    In a covered region, select the eSIM for mobile data and enable roaming as required. Complete any scheduled or manual activation. Successful installation does not necessarily start the validity period.

How to choose data and validity

These starting suggestions assume a 5–7 day trip. Actual usage depends on video, photo uploads and hotspots. Choose validity covering every day from arrival to departure; available allowances are shown in the plan list above.

Light use · 5 GB total

For a 5–7 day trip mainly using maps, messaging and itinerary checks, with hotel Wi-Fi, consider 5 GB total. This is shared across the full validity period, not 5 GB per day.

Everyday travel · 2 GB per day

For daily navigation, social media and photo uploads, consider 2 GB per day. For a 7-day trip, choose a 7-day daily 2 GB plan and check its daily reset time.

Video and hotspots · from 20 GB

For frequent video, video calls or laptop tethering on a one-week trip, compare total-data plans from 20 GB. Choose more for longer trips or heavier video use, and confirm hotspot support.

These profiles describe local operators and their official network information. They do not mean every travel eSIM can access these networks. Use the selected plan’s network list above.

AIS - Thailand's Largest Network

Advanced Info Service (AIS) holds the widest nationwide coverage in Thailand, excelling in both urban and rural areas. With extensive 5G deployment across nearly all provinces and consistently top-ranked performance, AIS is the most reliable choice for comprehensive connectivity.

TrueMove H - Speed Leader in Cities

Part of the True Corporation group, TrueMove H delivers the fastest 5G speeds in Bangkok and major cities, often reaching 100-200 Mbps. Following its merger with DTAC, it now commands the largest combined subscriber base in the country.

DTAC - Reliable Urban Coverage

Now operating under True Corporation after a 2023 merger, DTAC maintains its own branding and network. Known for strong reliability in urban areas and competitive pricing, it remains a solid option for travelers staying in Thailand's main cities and tourist zones.

4G and 5G identify supported network types. Actual connectivity depends on device bands, surroundings, terrain and network load. If you cannot connect, check the mobile data line and roaming settings, then try manually selecting a supported operator.
