Confirmed from each provider's own site — see the trust card on each provider page for the verification date.

ID verification

AeriSIM: Not confirmed yet

Skyalo: Not confirmed yet

Refund policy

AeriSIM: Full or partial refund, or a replacement, if the eSIM can't be installed or used due to a fault on AeriSIM's or the carrier's side; incompatible or carrier-locked phones are refunded minus $2 or 10% (whichever is higher). No refund once installed, for changed plans, or after the activation window.

Skyalo: Refunds and cancellations are handled case-by-case via support — eligibility depends on whether the eSIM was already installed or used; contact support with your order number.

Validity starts

AeriSIM: Validity starts once the eSIM connects to a supported network and begins using data; you can install before departure but keep it switched off. Some plans start on installation or a fixed date, as stated on the product page.

Skyalo: Validity starts either on eSIM installation or on first connection to a supported network, depending on the plan — check the specific plan's activation trigger before installing early.

Fair-use limit

AeriSIM: Varies by plan and is listed on each product page: daily plans slow down after the daily high-speed allowance (e.g. Japan: 128 kbps, resets 0:00 UTC+8); some unlimited plans have a stated speed cap instead.

Skyalo: Daily unlimited plans give a set volume per day at full speed, then unlimited data at a reduced per-plan speed, resetting every 24 hours; other unlimited plans may have speed reduced under Fair Use after heavy traffic.

Top-ups & rollover

AeriSIM: Depends on the plan: check My eSIMs and the order details; if a top-up is not offered, buy another plan for the same destination.

Skyalo: Many plans support top-ups: buy a top-up plan for the same country or region and the data is added to your existing eSIM profile (each plan shows Top-up Available/Not available).
