Thailand Daily eSIM: Never Run Out of Data
Daily-renewing data plan for your Thailand trip: choose 500MB–10GB high-speed data per day and the exact number of days you need (1–30 days). Once your daily high-speed allowance is exhausted, speeds are reduced: maps and messaging still work, unlike fixed-data plans where connectivity drops entirely.

- Lowest cost per GB: 10GB/day, about C$1.69 per GB of high-speed data.
- Speed after the daily cap depends on the plan: 1 Mbps on 1GB, 2GB, 3GB, but only 384 Kbps on 5GB, 10GB. A bigger plan doesn’t mean faster speeds once the cap is reached.
- Carriers also differ between plans: check the Carrier column if you need a specific network.

Using mobile data in Thailand: local tips
- dtac and TrueMove H share one network. True and dtac merged their towers and spectrum in October 2025, so whichever brand your phone shows, it runs on the same network.
- 5G where people are. AIS says its 5G reaches about 95% of Thailand’s population. Speeds still vary with crowds and your phone.
- Before island hopping. 5G has been extended along both the Gulf and Andaman coasts, but coverage on individual islands isn’t guaranteed: download maps and boat tickets before you set off.
- Ride-hailing with a foreign card. Grab in Thailand accepts credit and debit cards as well as cash. Bolt also operates in Bangkok and at Suvarnabhumi, Don Mueang, Phuket, Chiang Mai and Chiang Rai airports.
- Pay by Thai QR code. Visitors whose banking apps are linked to Thai PromptPay (including from Japan, Korea, China, Singapore, Malaysia, Vietnam and Hong Kong) can scan Thai QR codes directly. Most Western banking apps are not linked yet.
Checked against official sources in September 2026. Services and coverage change: check the app or operator before you travel.
FAQ
Depends on your chosen plan: 500MB/day → 512 Kbps; 1GB/day → 1 Mbps; 2GB/day → 1 Mbps; 3GB/day → 1 Mbps; 5GB/day → 384 Kbps; 10GB/day → 384 Kbps. After that, you stay connected until your daily high-speed allowance resets.
eSIM plans for Thailand connect via AIS, dtac, TrueMove H. Your device automatically selects the strongest local network; 5G is available where supported by the carrier, otherwise 4G/LTE applies. The specific carrier for each plan is listed on its detail page.
Daily plans provide a fixed amount of high-speed data refreshed each day (e.g., 1 GB/day). Once the daily high-speed limit is reached, speeds are reduced but connectivity remains. The full high-speed allowance resets the next day. Fixed-data plans end completely once exhausted; additional data must be purchased.
Essentially similar to "unlimited" plans on the market: you always stay connected, but speeds are reduced after exceeding your daily high-speed data allowance. We clearly state the reduced speed for each plan so you can choose the right one. No vague marketing.
Select the exact number of days for your trip, from 1 to 30 days. Pricing is per day: travel for 5 days, pay for 5 days. No need to overbuy a 30-day package.
1 GB/day is enough for maps, messaging, and social media. 2–3 GB/day if you frequently watch videos or make video calls. 5–10 GB/day for livestreaming or sharing a hotspot with your group.
For most plans, validity starts from the first time your eSIM connects to a network at your destination. You can safely install it at home before flying. Exact details for each plan are clearly stated on its product page.
