Refund policy

abesteSIM: Full/partial refund or replacement if the eSIM fails to install/activate/work due to a fault on abesteSIM's or the carrier's side, or works only intermittently. A 2.5 SGD or 10% (whichever is higher) processing fee applies for device-incompatibility/carrier-lock refunds. No refund for wrong purchases, an expired activation window, expired unused data, wrong checkout email, or once the eSIM has been installed.

InternationalSIM: 14-day money-back guarantee: full refund if the eSIM QR code has not been scanned or activated, processed to the original payment method in 3–5 business days.

Validity starts

abesteSIM: Most plans start when the eSIM first connects to a supported network and begins using data; some instead use a fixed start date or activate on installation — stated per plan on its own product page (per their FAQ).

InternationalSIM: Smartstart: plans activate automatically on arrival in a covered destination, with the validity period starting then, not at purchase; unactivated plans expire automatically 6 months after purchase.

Fair-use limit

abesteSIM: Some unlimited plans apply a fair-use policy after a high-speed threshold; others state a fixed speed cap (e.g. 5/10/20 Mbps) instead — varies per plan, check the product description (per their FAQ).

InternationalSIM: Data services are subject to Fair Use Policies set by the local network carrier per InternationalSIM's terms, but no specific data threshold or throttled speed is disclosed.

Top-ups & rollover

abesteSIM: No — abesteSIM does not currently support topping up an installed eSIM; buy a new plan once the existing allowance ends (per their FAQ).

InternationalSIM: Existing eSIMs and SIM cards can be recharged with more data through the InternationalSIM customer portal without needing a new eSIM.

Lost device / reinstalling

abesteSIM: A lost/misplaced QR code can be resent by contacting support (email or live chat) before installation, when eligible. Once installed, an eSIM is bonded to that device and can't be transferred or reissued — contact support about a replacement rather than a reissue.

InternationalSIM: A new eSIM would be required.

Billing currency

abesteSIM: Users in Canada, Europe, the UK, Hong Kong, Japan, Taiwan, and the USA can pay in their local currencies; users in other regions are billed in SGD.

InternationalSIM: All InternationalSIM product listings and checkout prices are calculated and charged in EUR (€), including VAT.
