Phreeli, a new privacy-first mobile virtual network operator, is rolling out a “ZIP Code Only” prepaid plan that it says lets customers nationwide activate service on T-Mobile’s network without providing their name or street address, Monday. The company says it uses a zero-knowledge, “double-blind” payment system designed to confirm service is paid for while keeping payment details separate from the phone number, Dec. 22, 2025.
Phreeli is positioning itself as a direct response to the way conventional wireless accounts often bundle identity, billing and usage into a single record that can be breached, brokered or demanded through legal process. Its bet: that “privacy by default” can be a consumer feature, not a niche workaround.
How Phreeli’s “ZIP Code Only” signup is supposed to work
Phreeli says its default signup flow relies on a ZIP+4 code and a username, with the ZIP code used for taxes and fees rather than identity verification. Optional add-ons such as an email address can improve account recovery, but the company’s marketing frames those details as a choice, not a requirement.
On Phreeli’s website, the carrier lists plans starting at $25 a month for its “Flex” option and scaling to $85 a month for 40GB of high-speed data, with taxes and fees included. The service also emphasizes eSIM activation, which can reduce the need for a shipping address and mailed SIM kit.
Reporting from Android Authority said Phreeli supports downloading an eSIM through a Tor-hosted signup path for customers seeking an extra layer of anonymity, while still offering a physical SIM for those who want one.
Why Phreeli is betting on zero-knowledge payments
Phreeli’s most unusual claim is in its billing architecture. In an interview with Wired, founder Nicholas Merrill described the approach as a way to “separate the personally identifiable information of a person from their activities on the phone system.” The company’s “Double-Blind Armadillo” design is described as using zero-knowledge cryptography — a method that can prove something is true (such as “this line has paid”) without revealing the underlying sensitive details.
The concept is not new in cryptography, but it is unusual in consumer telecom. A 2016 explainer from IEEE Spectrum described how Zcash used zero-knowledge proofs so transactions could be validated without exposing who paid whom — the same broad idea Phreeli is now trying to apply to a monthly phone bill.
Phreeli says customers can use traditional payment methods or prepay with privacy-focused cryptocurrencies. In its launch announcement distributed via Business Wire, Merrill framed the strategy as risk reduction: “We tackle privacy at the front end, because if you don’t provide data, it can’t be lost or sold.”
What Phreeli can and can’t protect
Phreeli’s message lands in a market still shaped by years of concern about location and subscriber data. The Federal Communications Commission fined major wireless carriers in 2024 for unlawfully sharing customers’ location information, according to The Associated Press.
But privacy advocates also caution that “anonymous signup” is not the same as “invisible phone.” Even if Phreeli collects minimal customer details, cellular networks still log device and connection metadata, and phones broadcast identifiers as they connect to towers. A critique from Privacy Guides argued that marketing can blur the real-world limits of MVNO privacy, especially when the underlying network can still be compelled to produce technical records.
For Merrill, the business is also an extension of a long-running privacy fight. The ACLU detailed his National Security Letter case and the lifting of an FBI gag order in 2015 in “A Decade-Old Gag Order, Lifted.”
Whether Phreeli becomes a lasting category — or remains a specialized option for people who need to minimize the data trail behind a phone number — will likely depend on how many customers decide that a little friction is worth a lot less paperwork.
