## How the brands work

What each brand's own pages say (5 of 14 brands checked; the rest: see their sites).

| Brand | App or account | When days start | Refunds | Top-ups |
|---|---|---|---|---|
| Inbox eSIM (ours) | None: no app and no account | When the eSIM first connects to a network in a covered country | Unused and never installed: refund to the card within 30 days, less the card fee (no card fee within 14 days in the EU and UK) | Yes, on the same eSIM, from the order page |
| Airalo | Account required: you sign up or log in before buying, on airalo.com or in the Airalo app. | Most packs start when the eSIM connects to a supported network at the destination; some start on install. | "Wrong purchase" or "plans changed": Airmoney credit only. Install or not-working issues: Airmoney or card. | Only on eSIMs marked rechargeable; optional Renewals buy the same pack again when 10% data is left. |
| eSIMfly | Buy on the website or in the app; the QR comes by email and in your account. The pages do not say whether sign-up is needed. | Not checked by us | Full refund for an unactivated eSIM within 30 days, to the original method; instant-activation plans are not refundable. | Yes, where available: buy a top-up in your account on the app or website. |
| MegaEsim | Account required to buy, on the website or the app; the QR is emailed and kept under My eSIMs. | Not checked by us | Full refund for any reason within 6 months, installed or not, to the original method in 3 to 5 business days; plans with a phone number excluded. | Yes: log in, open My eSIMs and choose Top Up; data is added to the same eSIM, except some daily unlimited plans. |
| nadanada | No app needed: buy without an account, email or KYC; the eSIM details show right after payment. | Not checked by us | Generally non-refundable once delivered and used; refunds for technical issues via support. A never-used eSIM is not addressed. | Yes: add bundles to the same eSIM from its profile page; they queue and start when the current one ends. |
