About eSIMCard

Still researching: Founded

Headquarters: Longwood, FL, USA
Legal entity: ESIMCARD LLC
Website: esimcard.com
Refund policy: No refunds once the eSIM is installed and used; refunds within 30 days for coverage issues preventing installation, technical problems with no data consumed, or unauthorized purchases. Read the policy ↗
Validity starts: The eSIM activates automatically when the first byte of data is consumed at the destination, not at purchase, so it can be bought and installed well in advance.
Fair-use limit: Unlimited bundles include an allowed amount of full-speed data per rolling 24-hour period (starting from first use), after which speed drops for the rest of that period before resetting.
Top-ups & rollover: Existing eSIMs can be topped up or extended with more data through the eSIMCard app, which also lets you manage active plans.
Lost device / reinstalling: eSIMCard says re-downloading/reinstalling the same eSIM on the same device generally isn't possible -- disable it instead of deleting to keep your plan; if deleted, contact support with your QR code or ICCID.
Billing currency: All eSIMCard transactions are processed and charged in US Dollars (USD).
