No company in the table publishes measured speeds for Thailand, so this answer rests on the networks and network types each company names on its own pages, read 20 October 2026.

• AIS, True and dtac: HelloRoam (5G shown), MobiMatter (5G listed for each), Nomad eSIM Partner (which plans have 5G is not listed), Roamless ("up to 5G"), Truely (also Hutch; 5G in major cities).
• AIS and dtac: PuraSIM (AIS 5G, DTAC 5G); Kolet (on its business page).
• AIS and TrueMove H: Telcomia (5G on TrueMove H).
• AIS only: aloSIM ("LTE/5G"); KnowRoaming (5G in the cities and resort towns, 4G LTE elsewhere); Global YO (4G / LTE; 5G is not mentioned).
• True and dtac: Holafly; Sim Local names True; its FAQ names DTAC.
• True alone or with others: Airalo (True "+1 other"); Travelsim (TrueMove or Real Future); Orange Travel (AWN, National Telecom, True move, dtac TriNet); Eskimo (AWN).
• Not named: Saily, Jetpac, Roamify, BNESIM, Maya Mobile, Firsty.

Among the providers on this page, Airalo's 20 Mbps on unlimited plans, up to 3GB a day, is the only speed promised in the table.

Is an eSIM or a local SIM better for a month in Thailand?

Uncompromised Travel compares travel eSIMs only and holds no local SIM prices, so it cannot say which is cheaper; the travel eSIMs read on 20 October 2026 sell 30 days of data in Thailand at €5.60 for 10 GB (Telcomia) or EUR 39.99 for 100 GB (BNESIM), but most say they are data only.

What the table does show for a month:

• Price per gigabyte on 30-day plans: Telcomia says "From €0.20 per GB"; BNESIM 100 GB for EUR 39.99; Jetpac 40 GB for USD 29.99.
• A Thai number: MobiMatter's True Thailand Happy Tourist eSIM "comes with Thailand mobile phone number", for incoming calls and SMS only, valid 10 days. aloSIM gives a Hushed number of a country it does not state.
• Data only: BNESIM, Global YO, HelloRoam, Jetpac, PuraSIM, Telcomia, Maya Mobile, Firsty, Eskimo and KnowRoaming state that their eSIMs carry no phone number, calls or texts.
• Roamless: its app sells local numbers for calls and SMS, listed for the US, UK, Canada and Australia, on a separate subscription; its data plans are "Data only". No Thai number is listed.

If a Thai number matters for the month, check MobiMatter first and ask a local operator for its own terms. If data is all that matters, the 30-day plans on this page need no shop visit.

Which to buy first

3. Saily or Jetpac, for unlimited data with 5 GB or 3 GB a day at full speed written on the page.
4. Nomad eSIM Partner, if the trip also covers Singapore or Malaysia.
5. PuraSIM or BNESIM, for a stay longer than 30 days.
