On cost per gigabyte, the best Roamix plan for Thailand is 50 GB for 10 Days at $18.65 — about $0.37 per GB. The cheapest headline price ($0.85) is a smaller bundle, so it costs more per gigabyte. Pick the entry plan for a short trip and the value plan if you expect to stream, map or tether.

Is Roamix the cheapest eSIM for Thailand?

Not always. Roamix has the lowest entry price for Thailand of any provider we track. Entry price alone can mislead, though — a cheap 1 GB bundle often costs far more per gigabyte than a mid-size plan. Compare the full Thailand table before deciding.

Does Roamix support 5G in Thailand?

Yes — 622 of 623 Roamix plans for Thailand run on 5G where the local network supports it. Actual speeds depend on your device, your location and how busy the host carrier's network is.

How do I install an Roamix eSIM?

QR code delivered instantly after checkout. Buy before you fly while you still have home connectivity, but do not activate until you land — validity usually starts on first connection to a local network, not at purchase. Your phone must be carrier-unlocked and eSIM-capable.

Can I top up an Roamix Thailand plan?

Roamix offers Thailand plans up to 365 days, so for longer stays it is usually cheaper to buy the longer plan up front than to top up a short one. Top-up availability varies by plan — check the plan detail before you buy if you expect to extend.

The short answer

Roamix has the lowest entry price for Thailand of any provider we track.

Best value on cost per gigabyte is 50 GB / 10 Days at $18.65 ($0.37 per GB).

Is Roamix a good choice for Thailand?

Roamix's catalogue is unusually deep — tens of thousands of plan permutations — and it leans heavily on unlimited day-passes with a daily high-speed allowance that throttles rather than cutting off. That structure suits travellers who want predictable daily cost and don't want to estimate total data up front. Most Roamix inventory is 5G where the local network supports it, which is not true of every competitor at this price point.

Where it wins

✓Unlimited day-passes with throttle-not-cutoff fair use
✓5G on most routes where the local carrier supports it
✓Very granular duration options, from 1 to 365 days

What to watch

!Daily high-speed cap applies before throttling
!Newer brand with a shorter public track record
