Policies compared

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

ID verification

co:sim: Not confirmed yet

RoamGo: Not required

Refund policy

co:sim: Uninstalled eSIMs refunded unconditionally within 30 days of purchase; once installed, refundable only for a technical issue on co:sim's side.

RoamGo: All sales are final once the eSIM is installed or activated. A refund or replacement is granted where the eSIM failed to activate because of a verified technical fault, after support was given a chance to troubleshoot. Requests must reach support within 30 days of purchase. No refunds for an incompatible or locked device, skipped install instructions, a deleted profile, data already used, or changed travel plans.

Validity starts

co:sim: Not confirmed yet

RoamGo: The validity period starts at the activation event named on each product page, and it genuinely differs per plan: some start on successful payment, others on installation, manual activation, or first connection to a supported network. Each plan page states which rule applies before you buy.

Fair-use limit

co:sim: Daily plans throttle to a lower speed (e.g. 512Kbps) once the daily limit is reached; total-data plans simply stop once depleted.

RoamGo: Fixed-data plans are one bucket for the whole trip - no daily reset and no throttling until the bucket runs out. RoamGo also sells daily-allowance plans, which run at reduced speed after each day's high-speed cap; those are not listed here. Their Terms state that advertised speeds are theoretical maximums from the local carrier, not guaranteed throughput.

Top-ups & rollover

co:sim: Top up your balance anytime on the website -- instant, choose from various amounts; PAYG deducts per MB, data packages from $0.90/GB.

RoamGo: Top-ups are per plan, not provider-wide: each plan page says "Top-ups available" or "No top-ups on this plan", and RoamGo state they make no promise where the carrier has not confirmed. Where a top-up applies it reuses the same eSIM and QR code with no reinstall, and is priced separately by the carrier. Some plans stay eligible for a limited grace period after expiry.
