Policies compared

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

ID verification

ByteSim: Not confirmed yet

Esimatic: Not required

Refund policy

ByteSim: Full or partial refund for connection issues, depending on the situation; no cancellation fees and a money-back guarantee (ByteSIM FAQ). Full terms are on their Refunds Policy page.

Esimatic: Refunds within 30 days of purchase, only when the eSIM can't be activated due to a technical problem on Esimatic's side after troubleshooting; an installed eSIM is considered used and non-refundable.

Validity starts

ByteSim: Most plans start when the eSIM first connects to a network at the destination; some start on a selected date, in the app or (e.g. the Giffgaff UK eSIM) from purchase, as stated on the product page. Installing early usually does not start the plan; some QR codes must be used within 180 days.

Esimatic: Validity starts when the eSIM auto-connects and uses its first 1KB of data at your destination, not at purchase; unused bundles expire 12 months after purchase.

Fair-use limit

ByteSim: Unlimited plans may be subject to a local operator fair-use policy: heavy use in a short period can be temporarily slowed or deprioritised (1080p streaming still possible), lifted the following day. The per-plan speed policy is stated on each product page.

Esimatic: Day Plan: 1GB of fast 5G data every 24 hours then throttled to 1.25 Mbps; Day Plan+: 2GB fast data daily then throttled to 2 Mbps -- both stay unlimited overall, never fully cut off.

Top-ups & rollover

ByteSim: No top-ups or extensions: data on an existing eSIM cannot be renewed; buy a new eSIM when you need more (ByteSIM FAQ: not supported due to the anonymous nature of their eSIM products).

Esimatic: Top up by buying the same eSIM bundle again from the Esimatic shop on the existing eSIM; no reinstall needed.
