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.

WorldSIM: Unused, unopened items can be returned within 14 days for a full refund minus postage; faulty products are exchanged or refunded after testing confirms the fault.

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).

WorldSIM: Lifetime validity on the airtime credit itself, as long as you top up at least once within the airtime validity period (30/90/180/365 days depending on the bundle bought) to keep it active.

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).

WorldSIM: Not confirmed yet

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).

WorldSIM: Pay-as-you-go: top up airtime credit any time it runs low (via account or short-code), then convert credit into data/call/SMS bundles for any destination — no new eSIM or QR scan needed.

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.

WorldSIM: Not confirmed yet

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.

WorldSIM: Checkout offers a currency selector (GBP default, plus AUD, CAD, EUR, INR, ZAR, USD) — the price and currency you pick is what is charged.
