Tested the no-KYC eSIM providers that take BTC, some things to know

[Alex_GGG]

Most "anonymous eSIM" recommendations that I found are years old and half of them predate the providers worth using now. Tested on a Pixel 8a and iPhone 16 Pro, goal was to maximize ISP anonymity, platform access and general privacy, paying in BTC the whole way. I bought plans from the main no-KYC providers and activated each one on the device, test took a few weeks while traveling across EU/Asia. Notes below, focused on Bitcoin support (Lightning vs on-chain), activation and IP routing since that's what matters here.
All of them skip KYC and take crypto, but how they handle Bitcoin varies, some are Lightning-first, some on-chain, some run their own processor. Activation flow same for all phones: scan the QR under Settings > Network & internet > SIMs > Add eSIM. If the code did not work, I used the GrapheneOS eSIM string. Here are results:

Silent Link

The established one. 160+ countries, no caps or expiry, pays in BTC/Lightning/XMR/stables, data and call packages. Lightning supported directly, which keeps the payment fast and cheap. Activates cleanly on GrapheneOS, string available as well. Strongest community trust and the best reports for working globally. Downsides: most expensive, eSIM management pretty outdated, you only get one exit IP and no visibility into it before buying (need to ask support), and popular regions sell out fast.

LNVPN (nadanada)

Widest payment range (BTC, XMR, Zcash, ETH, USDT, even cards) and cheap entry. Lightning-native, as the name suggests. Bundles a VPN, phone numbers and some sort of anon AI chat thing. In testing: no routing disclosure, thin plan selection, hotspot didn't work, and I couldn't get a clean activation on GrapheneOS. Used an iPhone 16 Pro to activate. Not sure what privacy features they provide, but they have some community which is pretty positive.

Voidmob

Lets you pick and filter the exit country and carrier, most IP routing options available. Actually bypasses RU VPN restrictions and CN Great Firewall without a separate tunnel. Activates fine on GrapheneOS, have string and docs. 200+ destinations, BTC/XMR/SOL/stables. Bundles non-VoIP numbers and vless xray mobile proxies, detailed dashboard to manage identities. Downsides: newer service, eSIM is data-only, crypto only (which is a plus here).

PikaSim

Mostly per-country pricing, self-hosted BTCPay so no third-party payment processor sees the transaction, on-chain and Lightning both go through that same self-hosted setup. Shows your IP location on the order, so you know your exit before you connect. SMS and calls on US plans. Cards via Stripe if you don't mind that trail. Cons: newer, only a handful of routing options. Checking price country by country is annoying, or just grab a global plan but no bundles.
Things worth knowing if you're paying in BTC:

No-KYC is not the same as anonymous. The carrier still sees the eSIM IMEI and logs IP at the network level, and the eSIM adds no encryption on its own. What you do avoid disclosing: your home ISP, your identity, and (if the provider routes properly) your real-country IP. Worth remembering on-chain BTC is permanent and public, so if the coins came from a KYC exchange the purchase is traceable, Lightning or a self-hosted processor like PikaSim's BTCPay reduces that.
Routing transparency is the thing nobody checks until a banking or auth app locks them over a location mismatch. Some of these providers don't tell you the exit at all.
Verify your exit IP right after activation. Settings won't tell you, use a checker before sending anything sensitive.
For real encryption, the eSIM is just connectivity. Layer a VPN or mobile proxy on top depending on your threat model. The eSIM solves the SIM-registration and foreign-IP problem, not the encryption one.

Pick by use case, each has tradeoffs.

Add Globalesim to the list. Good provider that accepts crypto, and the exit node is somewhere in Poland or Israel (from my experience). They offer a Flex plan that allows for unlimited recharging of data, but you're basically paying roaming prices at this point, and I wouldn't recommend such expensive providers unless you absolutely had no other choice.

[The Cryptovator]

I know there are eSIM companies, but I have never used one. I have used virtual SIM cards before for my clients, like opening Telegram and vice versa. All the eSIMs will charge you a roaming cost, and most probably it's higher than our native roaming charge. I know you are talking about non-KYC e-SIMs, but you are always traceable by the operator. It's even possible to trace your exact location through your device and e-SIM.

However, probably I won't use it, such as a SIM card, unless I am forced to. Because it isn't necessary to use eSIM like this with a high charge unless I am involved with any crime. Because I have a roaming SIM card that works in almost all the countries I visit. Also, there is not much charge for the roaming compared to the eSIM. So not interesting to me.

I have similar thoughts to The Cryptovator on these eSIMs.  I like that they are no Know Your Customer, although you can still get pre paid SIM cards in my country with no ID.  But I rather have a phone with no SIM at all, whether electronic or physical.  Other than the fact that it is closer to pre paid SIMs as it asks for no private information, there is pretty much no other advantage for the usually much extra prices.
