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.

KnowRoaming: Full refund if the eSIM was never installed or the plan never connected; after that a full or partial refund is discretionary (under 2% of data used, or a fault on their side). Ask within 90 days of purchase and before validity ends; reviewed within 4 working days, paid within 15 calendar 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).

KnowRoaming: The plan starts when you first connect in a supported country, not at purchase; validity days count from that first connection and run continuously. It must be started within the 'Activate before' window shown at checkout. Unused data expires with the validity period, no rollover.

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).

KnowRoaming: Unlimited country plans: 5 GB at full speed every 24 hours, then reduced speed until the allowance resets (24h counted from first connection); the Global unlimited plan gets 2 GB a day, then up to 256 kbps. Hotspot use counts against the allowance. Fixed plans stop when the data is used.

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).

KnowRoaming: Top up from My plans in the app or on knowroaming.com: select the plan, tap Top up, choose extra data or days; no new eSIM, nothing to scan, the connection doesn't drop. Optional auto top-up (off by default) charges the saved card when the plan runs low.

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.

KnowRoaming: KR.One is one eSIM installed once; every later plan attaches to it with no new QR code. A deleted eSIM can't be restored or moved to another phone; a fresh one is added through the app in about a minute, while a plan with days or data left stays on the phone it was bought for.

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.

KnowRoaming: Charged in the currency shown at checkout (website: your region's currency; app: Settings > Currency). A card in another currency is converted by the card network at its own rate; KnowRoaming advises declining the bank's dynamic currency conversion offer. Card details are held by Stripe.
