eSIM privacy: who can see what
An eSIM is just a SIM in digital form, so its privacy depends on who handles your purchase and your traffic. Here's who can see what, using Zap eSIM as a worked example.
Short version: a no-ID, no-account checkout paid with Bitcoin means you share less when you buy. It doesn't hide what you do online from the mobile network, and no mobile plan is anonymous.
What the eSIM seller sees
At Zap eSIM: the plan you pick and the payment status. Your order details live in your private order link rather than a customer database. Our host keeps request logs (IP address, browser, page, time) for about an hour. The full list is in what we collect.
What the payment processor sees
Strike creates and confirms the Lightning invoice and receives the amount, order ID and payment data. Lightning payments aren't anonymous by themselves.
What the eSIM supplier and mobile network see
Our supplier, eSIM Access, and the network (Verizon and AT&T) see the eSIM's identifiers (such as ICCID and EID), its data usage, connection details and approximate location, as with any mobile plan. They don't get your name or email from us, because we don't have them.
What websites and apps see
Sites and apps you use see a mobile IP address from the network, plus whatever you tell them or they learn from your device.
eSIM vs physical SIM
Not much difference by itself. With either one, the network identifies the line and carries your traffic. What changes privacy is mostly how you buy it: what the seller asks for and how you pay.
Is an eSIM connection secure?
Traffic between your phone and the mobile network uses the carrier's standard encryption. That isn't a VPN or end-to-end encryption: encryption ends at the network, and older fallback modes are weaker. When we say "private, secure connection", we mean a no-ID checkout plus that standard encryption, nothing more.
How to add more privacy
- Use a reputable VPN to hide which sites you visit from the network.
- Use end-to-end encrypted messaging apps.
- Share less at sign-up everywhere, not just here.
Frequently asked questions
Is an eSIM more private than a physical SIM?
Not by itself. With either one, the mobile network identifies the line and carries your traffic. What changes privacy is mostly how you buy it: what the seller asks for and how you pay.
Can the mobile network see what I do?
The network carries your traffic and sees connection details and approximate location, as with any mobile plan. Encrypted websites and apps protect the content, and a VPN can hide which sites you visit from the network. None of that makes a mobile connection anonymous.
Is my connection private and secure?
Checkout is private: no account, no ID (no KYC), no email, and you pay with Bitcoin over Lightning instead of a card. Bitcoin payments aren't anonymous, but you don't hand over a name, card or ID to buy. The connection is a normal mobile data connection: traffic between your phone and the mobile network uses the carrier's standard encryption. It isn't a VPN or end-to-end encryption, and the mobile network still carries your traffic and can see connection details.
What does Zap eSIM keep about me?
Very little: your order details live in your own order link, our host keeps request logs for about an hour, referral records exist only if a referral link is used, and we keep support emails for up to 3 years. The full list is in what we collect and our privacy policy.
