Simsima: Not required

Refund policy

Roamify: Unused/unactivated eSIM purchases are eligible for review within 7 calendar days of purchase (must not be activated, installed, or consumed). Approved refunds are issued within 3 business days; banks/card networks may take a further 5-10 business days to post funds.

Simsima: Full refund if the eSIM hasn't been installed/activated, there's a technical failure on Simsima's side, or the wrong plan was delivered — not available once installed and connected to a network.

Validity starts

Roamify: Service begins immediately once the eSIM is downloaded and its data plan activated — validity starts on activation, not at purchase.

Simsima: Starts when the eSIM first connects to a network in the destination country, not at installation — you can install days or weeks ahead without losing validity.

Fair-use limit

Roamify: Unlimited plans are subject to a stated Fair Use Policy (preventing fraud/abuse), but no numeric high-speed cap or throttle speed is published — Roamify reserves the right to suspend/throttle without a stated threshold.

Simsima: No fair-use throttling on Unlimited plans — full speed for the entire validity period; only real network conditions may vary speed.

Top-ups & rollover

Roamify: Top-up is available in-app for supported eSIMs (not all — the app itself states when a plan can't be topped up), up until 2 hours before the plan expires.

Simsima: Add more data anytime from your Simsima account without reinstalling the eSIM.
