Cypher eSIM vs encryptSIM
encryptSIM is another no-KYC option with a Bitcoin-first stance. Coverage and payment breadth are where the two diverge.
Verdict first
Two no-KYC providers with similar posture; the deciding factor is whether your destination is on their list and whether you want to pay in something other than BTC.
Choose Cypher eSIM for wider coverage and six payment currencies including XMR.

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.
encryptSIM: is also a no-KYC seller, so the privacy comparison is close to a tie.
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 encryptSIM is the better choice
- No-KYC by design, same as Cypher eSIM — this is not a privacy-versus-convenience trade.
- Simple, web-only flow with no app to install.
Where it costs you
- A niche country list — check your destination is covered before committing.
- Bitcoin-first payment, so stablecoin and Monero users have fewer options.
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.
