Policies compared

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

ID verification

MicroEsim: Not confirmed yet

RoamGo: Not required

Refund policy

MicroEsim: Conditional refund: full/partial if your device is eSIM-incompatible, the eSIM never connects (full minus a small admin fee), or it works only intermittently (partial, prorated). No refund once the plan has expired unused, once installed on a device (no transfers), for a wrong checkout email, or a simple change of mind. Approved refunds go back to the original payment method, up to 30 business days.

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

MicroEsim: Validity starts when you activate data roaming on the eSIM (connect to the network), not when you first install/add it to the device.

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

MicroEsim: Unlimited plans: 'true unlimited' plans may be throttled for the rest of the day once usage typically exceeds 10GB in a single day (resets daily); plans with a high-speed cap drop to 128kbps once that allowance is used.

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

MicroEsim: No — an existing eSIM's data allowance can't be renewed or topped up; buy a new eSIM for more data (per their FAQ).

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.
