Refund policy

ByteSim: Full or partial refund for connection issues, depending on the situation; no cancellation fees and a money-back guarantee (ByteSIM FAQ). Full terms are on their Refunds Policy page.

MegaEsim: 100% money-back guarantee: ask within 6 months of purchase for any reason (installed, partly used or not) and get a full refund within 3-5 business days. Only exception: plans with a phone number are non-refundable. EU/EEA/UK buyers also keep the 14-day withdrawal right unless waived.

Validity starts

ByteSim: Most plans start when the eSIM first connects to a network at the destination; some start on a selected date, in the app or (e.g. the Giffgaff UK eSIM) from purchase, as stated on the product page. Installing early usually does not start the plan; some QR codes must be used within 180 days.

MegaEsim: Validity starts on first network connection at the destination, not at purchase or installation — installing the eSIM before a trip doesn't start the clock.

Fair-use limit

ByteSim: Unlimited plans may be subject to a local operator fair-use policy: heavy use in a short period can be temporarily slowed or deprioritised (1080p streaming still possible), lifted the following day. The per-plan speed policy is stated on each product page.

MegaEsim: Daily-cap "Unlimited" plans run at full speed up to their stated daily allowance, then throttle (per-plan capacityInfo, typically to 1 Mbps) until the next 24h reset.

Top-ups & rollover

ByteSim: No top-ups or extensions: data on an existing eSIM cannot be renewed; buy a new eSIM when you need more (ByteSIM FAQ: not supported due to the anonymous nature of their eSIM products).

MegaEsim: Top up anytime from your MegaEsim account or app (My eSIMs → Top Up); extra data is added to the same eSIM with nothing to reinstall. A few plans, such as some daily unlimited plans, can't be topped up.
