A Christian MVNO Just Launched With Mandatory, Unremovable Content Filters
Radiant Mobile launched on May 5 as the first US carrier plan to bake mandatory, unremovable pornography blocking into its network infrastructure — not as an optional parental control, but as a permanent feature no subscriber can switch off. The plan costs $29.99 a month for unlimited voice, text, and data on T-Mobile's 5G network. Researchers say there is no precedent for a US carrier enforcing network-level content blocks that adults cannot remove.
The network
Radiant is a virtual operator — it owns no towers and leases capacity from an existing carrier. That carrier is T-Mobile, though T-Mobile has publicly distanced itself from the arrangement. The company told MIT Technology Review it has no direct contract with Radiant; the relationship runs through a middleware company called CompaxDigital, which insulates T-Mobile from liability over Radiant's content policies.
The filtering technology comes from Allot, an Israeli cybersecurity firm that works with more than 500 carriers globally. Allot's domain-categorization system is what decides which sites get blocked. According to Cybercorsairs, network researcher David Choffnes at Northeastern University describes Radiant as the first US carrier to institute network-level blocks that cannot be removed even by adults — setting a potential precedent for other ideologically motivated MVNOs.
The filters
Pornography blocking is hard-coded and permanent for every account. A second filter, covering LGBT and transgender-related content, is enabled by default but can in theory be turned off. Founder Paul Fisher — a former fashion talent agent with no telecom background — told MIT Technology Review the goal is creating a "Jesus-centered environment."
The filtering works by domain category, which carries a documented overblocking risk. MIT's reporting flags a Yale University example where a subsection of a site could be blocked for transgender content while the main domain stays accessible — meaning legitimate health, news, and community resources can get swept up alongside explicitly adult material. Radiant has published no appeals process for subscribers who believe content has been wrongly blocked.
The business model
Radiant raised $17.5 million from Compax Ventures, with Nvidia VP Roger Bringmann as a lead silent investor. To build its subscriber base, the company has partnered with thousands of churches across the US, directing a share of each monthly bill to a subscriber's chosen congregation. It turns a phone plan into a recurring church donation.
Fisher has named South Korea and Mexico as expansion markets, citing their large Christian populations. Whether unremovable network-level filtering is legally viable under those countries' freedom-of-information laws has not been addressed. The FCC has not commented on whether mandatory carrier-level content blocking by a private MVNO raises consumer protection concerns — but the precedent is now set.
