Silent.link

Silent.link sells eSIM cards that provide mobile data and phone numbers without requiring any personal information. No name, no address, no government ID, no credit card. You visit their website, choose a plan, pay with Bitcoin or Lightning Network, and receive an eSIM activation QR code. Within minutes you have a working phone number and mobile data connection that is not linked to your real identity in any carrier database.

This solves one of the most persistent problems in crisis privacy: nearly every important service requires a phone number for verification — banks, messaging apps, email providers, social media, two-factor authentication. Your real phone number is one of the strongest identifiers that exists. It is linked to your name in carrier records, trackable in real time through cell tower triangulation, and routinely used by data brokers and law enforcement to build profiles. Silent.link provides a phone number that cannot be traced back to you through the carrier.

Silent.link is best suited for people who need a clean phone number for account verification, two-factor authentication, or short-term communication without creating an identity link. It is particularly valuable when setting up anonymous accounts for services that require SMS verification — a step that usually forces you to reveal your real phone number or use unreliable free SMS services that may not work with the platform you need.

Silent.link itself does not implement end-to-end encryption for voice calls or SMS — the eSIM provides a standard cellular connection, and calls and texts traverse the regular carrier network with standard carrier-level encryption (which protects against casual eavesdropping but not against the carrier itself or lawful intercept). The privacy value of Silent.link is in the anonymity of the number, not in the encryption of the communication.

For encrypted communication over a Silent.link number, pair it with Signal, WhatsApp, or another E2E-encrypted messaging app. Register the encrypted messenger using your Silent.link number so that your real number never appears. The eSIM's mobile data connection uses standard LTE/5G encryption between your device and the cell tower, which is adequate for general use but should be combined with a VPN for sensitive browsing.

Anonymous usage is Silent.link's core value proposition. The purchase process requires no personal information whatsoever. You access silent.link through a web browser (Tor is supported), select an eSIM plan, and pay with Bitcoin or Lightning Network. The eSIM activation QR code is delivered directly in the browser — no email address required to receive it (though you can optionally provide one for a backup copy).

Silent.link operates as an MVNO (mobile virtual network operator) and does not register subscriber information with the underlying carrier. Unlike buying a prepaid SIM at a retail store — where many countries now require ID scanning — Silent.link's online delivery and crypto-only payment create no identity record. The phone number you receive cannot be looked up in carrier databases to find a real name or address. For maximum anonymity, purchase the eSIM from Tor, pay with Monero-sourced Bitcoin (convert Monero to BTC via an atomic swap or exchange), and activate it on a phone that is not associated with your real identity.

Silent.link is not open source. The platform is a commercial service, and its backend infrastructure, MVNO integrations, and payment processing systems are proprietary. You cannot verify through code inspection that Silent.link does not retain logs or subscriber data beyond what they claim.

This means using Silent.link requires trusting the company's privacy claims. They state that they do not collect personal data and do not link phone numbers to identities, but this cannot be independently verified. The privacy community has generally found Silent.link's practices to be consistent with their claims, and no evidence of data retention beyond what is stated has surfaced. However, the lack of transparency is a meaningful limitation for users with the highest threat models.

Silent.link operates from outside the Five Eyes alliance. The company's operational details are intentionally opaque, which is both a privacy feature and a trust concern. They use carrier infrastructure from multiple countries depending on the eSIM plan you select, and the legal framework governing your phone number depends on the carrier network it is provisioned on.

Because Silent.link does not collect subscriber identity, they have minimal data to provide in response to legal requests even if compelled. However, the carrier whose network the eSIM operates on does see your device's IMEI and location data at the network level. Silent.link's protection is against identity linkage in subscriber databases, not against real-time network surveillance. For protection against cell tower triangulation and carrier-level metadata, combine Silent.link with a VPN for data and use encrypted messaging apps for all communication.

Silent.link has been operating since approximately 2020 and has built a reputation in the Bitcoin and privacy communities as a reliable source of anonymous phone numbers. The service is frequently recommended in privacy guides and forums. No security breach or data leak involving Silent.link has been publicly reported.

The primary trust factor is Silent.link's consistent delivery of anonymous eSIMs over several years without incident. The Bitcoin and Lightning payment model (no fiat payment processing that creates records) and the absence of an account system (no login, no stored data) align with their privacy claims. The risk is concentrated in the fact that Silent.link is a centralized commercial service — if the company were acquired, compromised, or compelled to change practices, users would have limited recourse.

Silent.link is remarkably easy to use. The website presents eSIM options with clear pricing, coverage information, and data/call allowances. The purchase process takes under five minutes if you already have Bitcoin. After payment confirms, a QR code is displayed on screen. You scan this QR code with your phone's camera (iPhone: Settings → Cellular → Add eSIM; Android: Settings → Network → SIMs → Add eSIM), and the eSIM activates within minutes.

The main usability barrier is the cryptocurrency-only payment requirement. If you do not already hold Bitcoin, you need to acquire some before you can purchase an eSIM. For someone who has already set up Cake Wallet and funded it (or has Bitcoin from Bisq), this is trivial. For someone new to cryptocurrency, it adds a prerequisite step. The eSIM activation process itself is straightforward and well-documented on the Silent.link website, with guides for both iOS and Android.

Silent.link eSIMs work on any device that supports eSIM technology. This includes iPhones from iPhone XS onward, most flagship Android phones from 2020 onward, and many mid-range Android devices. The eSIM standard is supported by iOS, Android, and some Windows laptops with cellular modems.

Coverage depends on the eSIM plan you select — Silent.link offers plans with coverage in the United States, Europe, and other regions. Some plans are data-only, while others include voice and SMS. Check the coverage map on the Silent.link website before purchasing to ensure the plan covers the countries you need. The eSIM can typically be transferred to a new device by re-scanning the QR code, though some plans have activation limits.

Silent.link accepts only Bitcoin and Lightning Network payments. No credit cards, no PayPal, no bank transfers. This is intentional — cryptocurrency-only payment ensures that no fiat payment processor has a record of your purchase. Lightning Network payments are particularly privacy-friendly due to their off-chain nature and onion-routed payment paths.

Pricing is denominated in sats (satoshis, the smallest Bitcoin unit) and varies by plan. Basic plans for SMS verification start at a few dollars equivalent. Plans with ongoing data and voice service cost more. For the most anonymous purchase: use Monero-sourced Bitcoin (convert Monero to BTC using an atomic swap or Cake Wallet's exchange feature), pay via Lightning Network (which provides additional privacy over on-chain Bitcoin), and access the site through Tor.

First, ensure you have Bitcoin available. If you have already set up Cake Wallet and acquired Monero, you can convert some to Bitcoin using the in-app exchange. Alternatively, acquire Bitcoin through Bisq or a Bitcoin ATM. You will need the equivalent of a few dollars to tens of dollars depending on the plan you choose.

Navigate to silent.link using Tor Browser or a VPN-protected browser. Browse the available eSIM plans and select one that meets your needs — if you only need a number for SMS verification, a basic plan is sufficient. If you need ongoing data and voice, select a plan with appropriate data allowances and regional coverage. Click to purchase and pay the Bitcoin invoice. If using Lightning Network, open your Lightning-compatible wallet and scan the payment QR code. Payment typically confirms within seconds on Lightning or within 10-30 minutes on-chain.

After payment confirms, Silent.link displays an eSIM activation QR code on screen. On your phone, go to Settings → Cellular (iOS) or Settings → Network & Internet → SIMs (Android) → Add eSIM, and scan the QR code. The eSIM will install and activate within a few minutes. You now have a phone number that is not linked to your identity. Use this number for anonymous account registrations, two-factor authentication on privacy-focused services, and as your public-facing number for situations where giving a phone number is required but privacy is paramount. Save the QR code and any confirmation details in your encrypted storage (Proton Drive or a Cryptomator vault) in case you need to reinstall the eSIM.
