What each brand says about the things that matter once you land, quoted from its own pages on 9 November 2026.
| Brand | Networks named | When it starts | Hotspot | Unlimited data |
|---|---|---|---|---|
| Graba SIM | SKTelecom, LG Uplus | 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 | SK Telecom, KT, LG U+ | 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 | SK Telecom, LG U+ | 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 | SK Telecom, LG U+ | 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. |

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.
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.
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.
