Turn your device upright to use CallSIMless.
You may request a refund review for unused prepaid credit. Credit consumed by completed calls is not refundable, except for duplicate or incorrect charges or where required by law.
To request a review, email support with the account email, payment date, amount, and reason for the request. If a call charge looks wrong, include the destination country and approximate call time.
Approved refunds are returned to the original payment method through the payment provider shown at checkout, and the corresponding unused CallSIMless credit is removed. Most approved refunds appear within 5–10 business days, although the bank, card issuer, or payment method can take longer.
