Best Site for Privacy SIM
Summary
The best site for a privacy SIM depends on whether your threat is SIM-swap fraud, telecom-side tracking, or full no-KYC anonymity. Efani is the strongest US option specifically engineered against SIM-swap attacks — accounts are PIN-locked at the carrier level. Cloaked Wireless is the newer privacy-MVNO entrant with no real-name requirement at signup. Silent.link is the global data-only eSIM that accepts Bitcoin Lightning Network and requires zero identity — the closest to fully no-KYC. JMP.chat provides a real phone number over Jabber with Lightning payment, useful for voice/SMS without a traditional carrier account. This page covers SIMs as your primary line; see [[no-kyc-esim]] for travel/roaming data and [[burner-phone-number]] for short-term virtual numbers.

Detailed rankings
Silent.link
No-KYC global data-only eSIM payable in Bitcoin Lightning
The default for no-KYC mobile data on a global trip or as a privacy primary-data line. Pair with a separate voice solution if needed.
Pros
- Zero identity verification — pay invoice and provision
- Lightning Network payment — no card, no bank, no email required for basic flow
- Global coverage with regional pricing
- eSIM profiles installable on any modern phone (iPhone XS+, Pixel 3+, modern Samsung)
- Includes a permanent phone number on some plans (UK number) for inbound SMS
Cons
- Data-only by default — voice calls are limited or unsupported
- Per-GB pricing is more expensive than carrier post-paid for heavy users
- Smaller operator — service interruptions have higher relative impact
- Number for inbound SMS is a UK number, may be flagged by some services
Price: Pay-as-you-go in BTC/LN; per-GB pricing varies by region

Efani
US carrier-grade SIM specifically engineered against SIM-swap attacks
The right pick if you hold serious crypto or are a known target. Different threat model from no-KYC — defense against attackers who would steal a normal SIM.
Pros
- Account locked at the carrier level — port-out requires multi-factor confirmation, not the standard carrier ID-check flow that has been social-engineered repeatedly
- Reportedly $5M insurance against SIM-swap loss for paid plans
- Targeted specifically at high-value targets (crypto, executives)
- Real US carrier service, full voice and SMS
- Strong reputation among the crypto OG community since 2020
Cons
- Premium pricing — well above mainstream MVNO rates
- US only
- Still requires identity verification — not no-KYC, it is anti-SIM-swap
- Insurance has terms and conditions that vary by incident
Price: Around $99/month for the privacy tier with insurance

Cloaked Wireless
Newer US privacy MVNO with no real-name requirement at signup
The right pick for US users who want privacy at the MVNO level without paying Efani prices and accept the newer-operator risk.
Pros
- Sign up without real name on lower tiers
- Bitcoin and major crypto payment accepted
- Runs on a major US carrier network — coverage is real
- Anti-SIM-swap protections at the account level
- Newer entrant with active product development
Cons
- Smaller operator — track record shorter than Efani or Silent.link
- Coverage limited to US
- Price not the cheapest US MVNO — privacy premium applies
- Some plan tiers do require verification — read the tier carefully
Price: Monthly plans from around $30

JMP.chat
Real phone number over Jabber/XMPP with Lightning payment
The right pick for a persistent privacy phone number that you actually own (covered in detail in [[burner-phone-number]]). Pair with a data eSIM like Silent.link for full coverage.
Pros
- Real persistent phone number you can give out
- Lightning Network payment — minimal identity
- Routes calls and SMS through Jabber/XMPP — your real number isn't on a carrier account
- Privacy posture friendlier than traditional MVNO
- Works with Cheogram client for easy daily use
Cons
- Number is VOIP-coded — major services (Telegram, WhatsApp, banks) may block
- Requires Jabber/XMPP setup — learning curve
- Voice quality dependent on network conditions
- No data plan — pair with a separate data SIM or WiFi
Price: Around $5/month, payable in Bitcoin Lightning

Mullvad VPN over standard MVNO + minimal-info carrier (last resort)
Layer privacy on top of any carrier when dedicated privacy SIM is not available
The right pick when no privacy SIM is available in your country. Hides traffic content, not identity at the carrier level.
Pros
- Works anywhere — does not require a special carrier
- Mullvad accepts cash by mail and crypto
- Layered approach — carrier sees no traffic, only encrypted tunnel
- Hides destination and content from the telecom
Cons
- Carrier still has your real-name account if you signed up the normal way
- Carrier still has your IMSI, IMEI, and location
- Phone number itself remains attributable
- Workaround for users who cannot get a privacy SIM, not a substitute for one
Price: €5/month Mullvad + whatever your MVNO costs

How we chose
- Threat model — SIM-swap defense, telecom-side tracking, or no-KYC anonymity.
- Identity requirement at signup — true no-KYC vs lighter verification.
- Payment options — Lightning/Monero strongly preferred for privacy.
- Coverage — global eSIM vs single-country MVNO.
- Voice/SMS support — data-only is not enough for some workflows.
- Distinct scope from [[no-kyc-esim]] travel and [[burner-phone-number]] virtual numbers.
Frequently asked questions
What is a SIM-swap attack?
An attacker convinces your carrier to port your number to a SIM they control — often via social engineering, sometimes via bribed insiders. Once they have the number, SMS-based 2FA on banks, exchanges, and email is theirs to use. Efani and Cloaked Wireless specifically defend against this with account-level locks that the standard carrier ID-check flow cannot bypass. The defense is most valuable for crypto holders and executives — anyone whose phone number is the recovery factor for substantial assets.
Is Silent.link truly no-KYC?
Yes for the basic flow. You pay a Bitcoin Lightning invoice and receive an eSIM activation code with no email, name, or ID required. This makes it the closest to fully anonymous mobile service available in 2026. Note that telecom regulators in some jurisdictions still require SIM registration with ID — Silent.link operates through carriers that allow data-only eSIMs without local-jurisdiction registration, which is permitted in some places and not in others. Verify your local rules before relying on it as a primary line.
Why does my number on JMP.chat or Silent.link get blocked by WhatsApp/Telegram?
Both services issue numbers that are classified as VOIP or virtual by upstream detection. WhatsApp, Telegram, banks, and exchanges maintain block lists of these number ranges. The pattern is the same as with [[receiving-sms-online]] services — detection improved sharply in 2022-2023. Pure-privacy numbers and major-platform compatibility are partially in tension.
Will a privacy SIM hide me from law enforcement?
No, not against a serious investigation. Carrier and MVNO infrastructure is subject to court-ordered disclosure. Silent.link and similar reduce trivial tracking (no marketing identity, no easy data sale) and remove low-effort attribution, but a determined investigator with proper legal process can usually identify a user via the carrier or the payment chain. Privacy SIMs are defense against bulk data collection and low-effort attackers, not against serious targeted investigation.
Can I use a privacy SIM as my only phone line?
Practically yes for data, harder for voice/SMS. Silent.link as data + JMP.chat for voice/SMS is a workable full-replacement combo. The friction is that recovery for banks, government services, and major platforms often requires a 'real' carrier number — keeping a minimal-use standard MVNO line for those bureaucratic use cases is the common compromise.
