What you get with Ubigi in Thailand

Set up before you fly
Buy in the Ubigi app and install your QR code at home. Your plan activates automatically when you first connect to a local tower in Thailand.
📱
Keep your existing number
Ubigi runs as a second line alongside your home SIM. Your usual number stays active for calls and texts — Ubigi handles data only.
🔥
Hotspot included
All Ubigi Thailand plans include hotspot sharing, so you can connect a laptop or tablet from the same data allowance with no extra fee.
📊
Real-time data usage
Track exactly how much data you've used at any time in the Ubigi app, so you never get caught short before your next refill.
☎️
Travel beyond Thailand
If your Thailand trip is part of a wider journey, Ubigi covers many other destinations from the same app — manage everything in one place.
📅
Flexible up to 30 days
Ubigi Thailand plans run up to 30 days from first use. Buy in advance so you're ready the moment you land.

Which Ubigi plan should you pick?

For a short city break of 3–5 days, the cheapest plan at £3.50 will cover Maps, WhatsApp, and casual browsing. If you're spending one to two weeks travelling around Thailand, step up to a mid-tier plan — usually the strongest value option on a per-GB basis in Ubigi's Thailand lineup.

If you plan to work remotely, stream video daily, or use your phone as a hotspot for a laptop, lean towards a larger bundle — the 25 GB option is the safer choice. The unlimited plans are priced at a premium but make sense for heavy users who don't want to track usage.

One thing to note: Ubigi Thailand plans are data-only. You won't get a local number, but your existing SIM handles calls and texts as normal. iMessage, WhatsApp, and FaceTime all work over data.

Ubigi eSIM for Thailand 2026 — what you need to know

Ubigi is a well-regarded eSIM provider with solid Thailand coverage. Plans range from short-break options to longer-stay packages, making Ubigi a flexible choice whether you're spending a long weekend or travelling for a month.

Thailand has three operators: AIS (Advanced Info Service, the biggest), True Move H and NT (the merged TOT/CAT, distant third). AIS has the deepest 5G footprint, claiming around 95% population coverage by late 2025, and True is close behind. 5G is now standard in Bangkok, Chiang Mai, Phuket, Pattaya, Krabi and Koh Samui. The smaller islands like Koh Lipe, Koh Tao and Koh Phayam have signal in the village areas but the dive boats and remote beaches drop fast. Khao Sok and the deeper jungle parks are mostly off-grid. The Bangkok BTS and MRT have signal in tunnels.

Is Ubigi good in Thailand?

In our testing, Ubigi connected reliably across major cities and travel routes in Thailand. Plug is type A/B/C (220V, the sockets often accept multiple plug types so a Europlug usually fits). Cash is still useful at street food stalls and night markets, but PromptPay QR code transfers have basically taken over for locals.
