Beyond the price: networks, activation and hotspot
What each brand says about the things that matter once you land, quoted from its own pages on 12 November 2026.
| Brand | Networks named | When it starts | Hotspot | Unlimited data |
|---|---|---|---|---|
| Graba SIM | TrueMove H, DTAC, True Move | Starts when the eSIM first connects in the destination, so you can install it at home. Each plan page states when it starts. | Hotspot works on every plan, using the plan’s data. | Fixed data only on these plans; day passes slow down after the daily allowance. |
| Airalo | Not named on the page we checked | Most packages start when the eSIM connects to a supported network in the coverage area; a few start on installation. Check the Validity Policy under Package Details. | Not stated as a general rule for fixed-data packages; on Airalo Unlimited, hotspot use counts towards the daily full-speed allowance. | Unlimited packages have a daily full-speed allowance, then slower speeds. |
| Nomad | AIS | Activate within 60 days of purchase; after that the plan activates automatically and the validity starts. | Nomad says its eSIMs support hotspot and tethering, using the plan’s data allowance. | Unlimited plans keep Nomad’s own speed policies. |
| Ubigi | AIS, TrueMove | Smartstart: the plan activates on arrival in a covered destination and the validity starts then. Plans not activated within 6 months expire. | Not stated on the plan page we checked. | Unlimited plans may have a fair use policy. |
| Yesim | Not named on the page we checked | Install it in a few steps and activate when ready. | Yesim lists hotspot mode for sharing data with other devices. | On plans with a speed limit, speed is reduced (throttled) once the limit is reached. |
| Holafly | Not named on the page we checked | The plan activates when the eSIM connects to a supported network and runs in 24-hour days from then. | Up to 1 GB a day can be shared as a hotspot. | Unlimited data only, priced by trip length; no fixed-data plans to compare like for like. |

Questions UK travellers ask
Which Thailand eSIM costs the least?
It depends on the size. Of the 6 sizes we could match on data and days, Graba SIM was lowest of these five brands on 1; on the others, Nomad was lower for 3 GB for 30 days; Nomad was lower for 5 GB for 30 days; Airalo, Nomad and Ubigi were lower for 10 GB for 30 days; Airalo and Yesim were lower for 20 GB for 30 days; Airalo and Yesim were lower for 50 GB for 30 days. Prices checked 12 November 2026.
Do these eSIMs allow hotspot?
Graba SIM plans do, using the plan’s data. Nomad and Yesim say theirs do. Holafly limits sharing to 1 GB a day. Ubigi’s plan page doesn’t say.
When does the plan start?
Graba SIM, Ubigi (Smartstart) and Holafly start when the eSIM connects in the destination, so you can install at home. Airalo says most packages work the same way. Nomad asks you to activate within 60 days of purchase.
Why isn’t unlimited data compared?
Unlimited plans have daily speed limits and hotspot caps, so they aren’t the same product as a fixed amount of data. We describe them instead of ranking them.
How do you check prices?
We read each brand’s own page with pounds selected on 12 November 2026, and match only plans with exactly the same data and validity. Graba SIM prices are live. Prices change, so check before you buy.
