co:sim cashback generally becomes payable after the order is confirmed, shipped, and past the return or cancellation period. The exact approval timeline is set by the cashback portal and co:sim.

After your co:sim cashback is approved and you reach the portal’s minimum payout threshold, you can request payment using the available methods, such as bank transfer, PayPal, or gift cards. Options vary by portal and region.

Many cashback portals require users to reach a minimum balance before withdrawing co:sim cashback. The threshold and payment rules differ by portal, so review the account or payout policy for current details.

Mobile purchases may qualify for co:sim cashback when made through the portal’s mobile app, mobile website, or tracked link. Use the method specified by the portal and avoid switching between apps or browsers during checkout.
