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.

Cellesim: Refunds only for technical failures caused by Cellesim that support can't resolve; locked/incompatible phones, user error (e.g. deleting the eSIM), wrong-device installs and change of mind after delivery are non-refundable.

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).

Cellesim: The validity countdown does not start at install - it begins only when the eSIM first connects to the network at your destination, so installing early does not waste days.

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).

Cellesim: Carriers throttle the connection after the high-speed cap (often 5-20GB depending on tier); Plus/Premium tiers keep full speed longer.

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).

Cellesim: Where a top-up is offered for your eSIM, add data from your Cellesim account or app to the same eSIM profile without reinstalling; if none is available you need to buy a new plan.

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.

Cellesim: Deleting the eSIM or installing on the wrong device is treated as non-refundable per terms; no reinstall or device-transfer option is described.

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.

Cellesim: Checkout shows a currency selector (for example USD) and displays prices/top-ups in your chosen currency; no specific conversion-fee disclosure was found.
