A new US cell phone network marketed to Christians is set to launch Tuesday, with a feature that network security experts say has never been done before in the United States: permanent, network-level blocking of inappropriate content that cannot be disabled, even by adult account holders.

The network, called Radiant Mobile, operates on T-Mobile’s infrastructure. Rather than relying on app-based filters that users can simply delete or work around, Radiant blocks content at the carrier level -meaning it never reaches the device at all. If a site is blocked, it simply doesn’t load.

To power the filtering, Radiant partnered with the Israeli cybersecurity firm Allot, which sorts websites into more than a hundred categories. Blocked content includes inappropriate material, violence, self-harm, and gender related content. The core blocks cannot be removed by anyone on the network, regardless of account settings.

The novelty, as cybersecurity experts note, is the permanence. US carriers have long offered optional parental controls at the network level, but those can always be switched off. Radiant’s cannot.

What’s notable isn’t just the technology – it’s that the broader world is increasingly recognizing the scale of the problem and acting on it.

The frum community, which has long grappled with the same challenge, may find an opportunity in Radiant Mobile’s model. A similar network-level solution could potentially be adapted for frum families, whether by joining an existing filtered carrier – similar to how Webchaver already runs on Covenant Eyes, a non-Jewish platform – or by building something similar tailored specifically to halacha-based standards.

The plan costs $30 per month. The company has raised $17.5 million in investment and plans to expand internationally.
