Policies compared

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

ID verification
AeriSIM: Not confirmed yet
SparkRoam: Not required
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.
SparkRoam: Full refund if the eSIM is unused/uninstalled, a verified technical failure occurs, or the QR/activation details never arrive within 2 hours. Used/activated eSIMs are not refundable. Incorrect-purchase requests on an unused eSIM get Spark Roam Wallet credit instead of cash (full credit 0-7 days, voucher credit up to 1 year).
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.
SparkRoam: Validity starts when the eSIM first connects to a supported network, not at the moment of purchase.
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.
SparkRoam: Fixed-data plans have no fair-use cap. Unlimited plans throttle to a stated speed after full-speed use (confirmed real per-plan values: "Up to 10 Mbps" on India/Turkey/Taiwan, fully unthrottled on Japan) โ€” see each plan's own details.
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.
SparkRoam: Top-up is available from the SparkRoam customer Dashboard on the large majority of plans; a plan's own details page states when top-up isn't offered for it.
