Ubigi eSIM Plans for Thailand
What you get with Ubigi in Thailand
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.
