Put several co:sim eSIMs in one cart only after checking each item's refund terms and any order-wide promotional condition. One payment does not make every eSIM equally refundable. The useful convenience is a combined purchase with separate item details; it is not a promise that any traveler can cancel any part later.
An eSIM is a downloadable mobile-service profile. A cart can contain distinct packages for distinct devices or journeys. The decision here is whether you accept the monetary conditions of that combined purchase, rather than how to share installation codes or data.
No. A read-only checkout comparison on October 31, 2026 combined two actual packages: Japan 10GB for 30 days and Malaysia 20GB for 15 days. The quote showed different item policies. The Japan package started billing at first connection and could qualify for an uninstalled refund; the Malaysia package started billing at purchase and was marked non-refundable.
That same checked basket did not require a full-order refund. This matters: a mixed basket is not automatically a coupled promotional order. Equally, its ordinary item conditions do not prove that a different promotion allows the same selection of returns. Read what your particular checkout says.
co:sim's item-level disclosures let you identify this difference before paying. If one traveler's plans are uncertain, consider whether to finalize that item now. A separate order does not make a non-refundable package refundable or reset the eligibility of a promotion.
Write down the package, intended device or traveler, quantity, allowance, validity and refund label. For an item that may qualify, also note installation status and the applicable deadline. This prevents a combined payment from hiding the fact that one product has already begun service while another has not.
For the checked examples, both packages provide mobile data without an included local number, carrier calls or SMS. The Japan offer supports top-up, while the selected Malaysia offer is not reloadable or renewable. Those are package facts, separate from refund grouping. Top-up support does not revive an expired card.

The refund policy describes individual uninstalled eSIM refunds in multi-eSIM orders. It also says the amount reflects each eSIM's share of the payment, and coupon-order refunds use the actual amount paid. Read that together with each item's eligibility rather than treating “partial refund” as an unconditional right to return anything in the basket.
The general uninstalled paid-plan window is measured from payment and is capped by the activation deadline. Installed eSIMs are outside ordinary self-service eligibility; purchase-billed products and free items have exclusions. A technical service issue or a question outside self-service belongs with support, with no outcome promised here.
If a co:sim promotional checkout explicitly says all remaining eSIMs must be refunded together, assess that condition before accepting the purchase. This article does not claim such a promotion is currently available to everyone. It explains how to read that condition if displayed. A discounted item and a coupled promotional order are not interchangeable descriptions.
Combine them when all selected packages fit, their intended users are known and their individual and order-level terms are acceptable. The convenience is fewer checkout steps, not pooled eligibility. Keep a simple item list so a later question can identify the correct eSIM rather than the whole trip.
Wait on an uncertain item if paying for it now would commit you to terms you cannot accept. Buying it separately later means a new current quote and whatever availability applies then. Do not promise yourself that today's offer, package or total will still be available.
The purchase and payment terms describe installation details delivered by email after successful payment. In practice, wait for fulfillment instructions; payment and delivery are separate stages. Review compatibility before purchase, and do not install an uncertain item merely to organize everyone's phones while assuming installation leaves its refund options unchanged.
Choose the co:sim basket whose item conditions you are prepared to accept now. A clear list of what is refundable, what is not and what may be linked is more useful than a single reassuring label for the whole payment.
An individual refund can be available for an eligible uninstalled eSIM in a multi-eSIM order, as described in co:sim's refund policy. It is not guaranteed for every item or promotion. Check the eSIM's installation status, payment-based window, activation deadline and any exclusion such as purchase-billed service or a free item. Also read whether the actual checkout imposed a requirement to refund remaining promotional items together. The mixed Japan and Malaysia basket checked for this article had different item policies but no full-order requirement; that is evidence about that selection, not every future basket. If you cannot identify which condition governs, ask support about the exact order before installing or using the uncertain item. Keep the original confirmation so the relevant package, quantity and amount can be reviewed without cancelling another traveler's plan by mistake.
A separate order does not change a package's own refund conditions. The selected co:sim Malaysia 20GB/15-day package is marked purchase-billed and non-refundable; buying it alone does not make it eligible just because it has not been installed. Another item may have different terms, and an ordinary mixed basket is not automatically subject to a promotional together-return condition. The useful reason to separate or postpone an uncertain purchase is to avoid committing to that item before you are ready, not to bypass its policy or promotion requirements. Check the actual new quote and offer availability when you return. Do not assume a discount, package or eligibility will be preserved. If you already paid, the existing order's conditions govern; a second checkout does not cancel or improve the first purchase's monetary rights.
For an eligible discounted eSIM, the relevant amount comes from the actual payment allocated to that item, rather than its original listing price. The refund policy describes proportional treatment for multi-eSIM purchases and refunds based on the amount paid for coupon orders. A free item has no separate paid amount to recover. Any explicit promotional together-return condition can also affect which items may be selected. Do not divide a basket total equally when the packages or discounts differ, and do not assume unused data converts into a cash balance. Check the order's displayed refund information or ask support for the applicable amount. Eligibility must still be established first, including installation, timing and product exclusions. Keep the confirmation and item list so the payment and selected eSIM can be matched without relying on memory or a pre-discount screenshot.
