Policies compared

Confirmed from each provider's own site — see the trust card on each provider page for the verification date.

ID verification

KnowRoaming: Required for some countries (passport/ID)

ZenSim: Not required

Refund policy

KnowRoaming: Full refund if the eSIM was never installed/activated; if activated, a refund is discretionary and only offered if less than 2% of data was used, within 90 days of purchase.

ZenSim: Refunds are not available once the eSIM has been installed or activated, except for a technical failure verified by ZenSim. If a Travel eSIM cannot be used due to device incompatibility, a refund is issued only if it has not been installed/activated on a different device.

Validity starts

KnowRoaming: Packages last the full validity period once activated (first use in a supported destination); unused data expires when validity ends. Must be activated within 90 days of purchase, per KnowRoaming's own product info text.

ZenSim: Validity starts on activation, not purchase — the eSIM auto-activates the first time it connects to the destination network. Must be installed within 12 months of purchase or ZenSim may cancel the order.

Fair-use limit

KnowRoaming: Some fixed-data plans include a high-speed data allowance that renews every 24 hours, with speed reduced once the daily limit is reached; genuine Unlimited plans are marketed with no speed throttling. Exact daily threshold varies by plan and is not disclosed sitewide.

ZenSim: Unlimited plans include a fixed daily high-speed allowance (see each plan), then drop to a reduced speed for the rest of that day.

Top-ups & rollover

KnowRoaming: Existing eSIMs can be topped up from the My eSIMs section of your account (an Auto Top-Up option is also available), without reinstalling.

ZenSim: Every Travel eSIM can be topped up from the ZenSim app — no need to buy a new eSIM.
