Refund policy
Flysimio:
7-day money-back guarantee: full refund, no questions asked, if you contact them within 7 days of purchase and have used less than 100 MB of data (a genuine connectivity test won't come close to that). After 100 MB, refunds are only for a real fault โ QR/activation never arrived, a verified technical fault, undisclosed device incompatibility, or the coverage/data advertised not being delivered. Unused data does not roll over and is not refunded once the plan is running.
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
Flysimio:
You can buy any time โ plans have 6 months to activate, and validity only starts once your phone connects to the destination network (check each plan card for the exact window).
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
Flysimio:
Fixed-data plans aren't throttled; daily-unlimited plans slow to 1 Mbps after the daily high-speed cap (FAQ: 5 GB/day; the per-plan cap is on each plan card), with no hard cutoff.
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
Flysimio:
Top-ups are instant via the account dashboard โ same eSIM, no re-installation needed.
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.
