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.

Keepgo: You can cancel and request a refund by email or chat, but eSIMs not yet installed or activated must be claimed within 30 days of purchase; all refunds (except crypto) carry a 10% fee, and refills aren't refundable.

Validity starts

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

Keepgo: No expiry: the data balance is valid for a lifetime, but an account with no purchase, refill or usage for 24 straight months can be suspended and deleted (with its lines) after a 30-day email notice.

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.

Keepgo: Their Terms of Service (§12) apply a fair-use limit of 7,000 MB per month to all data plans; above that within 30 days Keepgo may suspend or restrict the connection.

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.

Keepgo: Refill any time from your Keepgo account in fixed packs (100 MB up to 50 or 100 GB depending on the bundle); Auto-Refill is available.

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.

Keepgo: QR codes only work on the first device; if you lose or change the phone or delete the eSIM, you buy a new eSIM and support moves the unused data to it (not for lines deactivated with under 100MB).

Billing currency

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

Keepgo: Refill prices are set in USD and EUR; set the account currency to EUR to pay with iDEAL or Bancontact.
