Cypher eSIM vs Saily
Saily is the travel eSIM from the team behind NordVPN, and it leans on that brand for trust. It is an app-first, account-based product — which is the opposite of what Cypher eSIM is built for.
Verdict first
Saily is a solid mainstream option and the brand is a fair reason to trust it. But its privacy story is about your traffic, not about what the store knows about you — and those are different questions.
Choose Cypher eSIM if you want the store itself to know nothing, not just the network.

Privacy
The difference that actually matters is what each company holds about you after the sale. Cypher eSIM stores the order — tariff, crypto amount, eSIM ICCID — and nothing that identifies a person: no email, no phone, no name, no card.
Saily: requires an account and email with card payment, and runs through an app that carries the usual analytics stack.
Two practical consequences. First, a breach can only expose what was collected, and an unasked-for field cannot leak. Second, a purchase history held next to a legal identity is a dated record of which countries you were in and when — worth thinking about regardless of how much you trust the seller today.
Where Saily is the better choice
- Backed by an established security company, which is worth something on trust alone.
- Clean app with bundled extras (ad blocking, a web-protection layer) that some travellers will actually use.
- Competitive pricing on mainstream destinations.
Where it costs you
- App-first means an install, an account and the analytics that come with a consumer app — three things a web checkout does not need.
- Card only. There is no path to buying without a bank record.
- A privacy-branded parent company does not change what the eSIM product itself collects: email, card and purchase history.
Coverage and network quality
Both run on the same underlying infrastructure: neither company owns towers. Every travel eSIM is wholesale capacity on local carriers, so in a given city the difference in speed comes down to which partner network the profile attaches to, not to the brand on the checkout page.
Country counts are marketing numbers industry-wide — they count "at least one reachable partner", not good 5G. Use them as a rough tier and check the specific country you are travelling to.
Other comparisons
Switching
- There is nothing to migrate. An eSIM profile is per-plan, not per-account, so trying a different provider is just installing one more profile — your existing one keeps working until it expires.
- Modern phones hold several eSIM profiles at once (typically 8–10) with one active at a time, so you can carry a spare for the next trip without deleting anything.
- Your phone number is unaffected either way. It lives on your physical SIM; the eSIM only ever carries data.
