Refund policy

4S: Refund eligibility is reviewed case-by-case based on order/eSIM status and reason — no fixed window stated; contact support to request review.

Sim Local: Full refund within 14 days if the eSIM has not been activated, no questions asked; failed activations caused by a technical issue are refunded even outside that window.

Validity starts

4S: Most plans start counting on first use, when the eSIM connects and begins using data (checked on your 4S service page).

Sim Local: Validity trigger varies by network operator - some start counting when the eSIM is installed, others only on first connection at your destination; check the specific plan for which applies.

Fair-use limit

4S: Unlimited plans include a high-speed data quota for the full validity period; after it is used, speed drops to up to 1 Mbps until the plan expires.

Sim Local: Unlimited plans include up to 10GB per day of full-speed data; consistently exceeding 10GB per day may trigger the Fair Use Policy and plan suspension, at the discretion of the network operator (no fixed throttle speed is disclosed).

Top-ups & rollover

4S: Self-serve top-up (same destination/region only) adds high-speed data to the current plan and extends its validity by the top-up package's own validity period.

Sim Local: Top-up ability and method depend on the network operator (for example the My3, EE, or Lycamobile apps or sites), accessed via Sim Local My eSIM account area; a few operators do not support top-ups at all.

Lost device / reinstalling

4S: Each eSIM QR/activation code can only be installed once; a deleted eSIM usually cannot be reinstalled with the same code — contact support for a replacement.

Sim Local: Sim Local warns that deleting an eSIM before its validity period expires may make it impossible to redownload, so confirm the eSIM has expired before deleting it.

Billing currency

4S: Checkout supports multiple currencies (USD, EUR, GBP, JPY, CNY and others via a currency selector); USD is the default.

Sim Local: Checkout supports multiple currencies including USD, GBP and EUR with prices shown in your selected currency; no explicit conversion-fee disclosure was found.
