Unlimited eSIM Thailand: Real specs before you buy
"Unlimited" means different things across eSIM providers. The table below shows exact details from the plan you’ll receive — including your high-speed data allowance, post-threshold speeds, and carrier — so you know exactly what you’re buying.
What can I still do in Thailand after using up my 1GB high-speed data allowance?
1GB high-speed data ≈ 3.3 hours of 360p video or 0.9 hours of 720p HD video (estimated using YouTube’s recommended bitrates). Once exhausted, speeds will be reduced to 1 Mbps until your daily allowance resets:
- Message WhatsApp, iMessage, Messenger
- Email and Google Maps navigation
- Voice calls via apps
- Browse social media and watch 360p videos
- Low-quality video calls
- HD video streaming, large file downloads, and hotspot sharing with a laptop
7 days in Thailand: Unlimited or data package?
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.

FAQs about Thailand eSIM
Everything you need to stay connected on your trip.
Unlimited data: your connection will never be cut off. However, high-speed data is limited to 1GB per day; once exhausted, speeds will be reduced until your daily allowance resets. Post-threshold speed in Thailand: 1 Mbps.
Connects via TrueMove H, dtac. Your device automatically selects the strongest available local carrier — no manual selection needed. 5G is available where the local carrier has deployed it; elsewhere, 4G applies.
At 1 Mbps these still work: Message WhatsApp, iMessage, Messenger, Email and Google Maps navigation, Voice calls via apps, Browse social media and watch 360p videos, Low-quality video calls. Not recommended: HD video streaming, large file downloads, and hotspot sharing with a laptop.
Unlimited (1GB/day high-speed data) starting at $1.62/day is enough for maps, messaging, and social media. Unlimited Plus (3GB/day) starting at $2.58/day is better if you frequently make video calls, post stories/videos, or share a hotspot with travel companions.
Yes. Note that hotspot usage counts toward your plan’s high-speed data allowance — a single laptop can quickly consume 1GB, and carriers may throttle speeds when hotspotting. For group sharing, we recommend Unlimited Plus or Premium.
The number of days starts when your eSIM first connects to mobile data at your destination — not from the purchase date. We recommend installing your eSIM before departure and only enabling it upon landing.
This plan routes traffic through an IP address located in HK. Some apps, streaming services, or websites may display region-specific content based on this location rather than your physical location.
Most iPhone XS+, Galaxy S20+, and Pixel 3+ models support eSIM. Your device must be unlocked.
No. This is a data-only plan; you’ll make calls and send messages via WhatsApp, iMessage, Messenger.
100% refund if the eSIM hasn’t been activated or if there’s a technical issue caused by us that we cannot resolve.
