Frequently asked questions
Is unlimited data really unlimited?
Most 'unlimited' travel eSIMs apply a daily fair-use throttle (often after 1–3 GB) and may restrict hotspot. For most travelers who don't heavy-stream, a 3–5 GB metered plan ends up cheaper and faster after the throttle kicks in.
Is YonoSIM cheaper than Holafly?
For short trips and metered usage, yes — typically by 40–70%. For users who genuinely need >1 GB per day every day, Holafly's unlimited plans can be competitive on long stays.
Does Holafly accept KakaoPay or Toss?
No. Holafly bills in USD/EUR via card networks. YonoSIM supports KakaoPay, NaverPay, TossPay, and Korean-issued cards via PortOne.
Can I tether to my laptop or tablet?
On YonoSIM, hotspot is allowed on most metered plans (check the plan page). Holafly's hotspot is typically capped or unavailable on unlimited plans.
