First-ever Christian mobile carrier seeks to address 'spiritual problem of lust'

By Samantha Kamman, Christian Post Reporter Tuesday, May 26, 2026

Reports of Generation Z helping drive a resurgence in church attendance have sparked optimism among many Christian leaders, but some pastors say the trend has not solved what they describe as a growing spiritual struggle among young people: pornography use.

Radiant Mobile, a newly launched phone network that describes itself as the “first-ever Christian mobile carrier,” was created in part to address that concern by offering families tools to block explicit content before children encounter it online.

“It’s not a judgment; we’re here to help people,” Chris Klimis, a pastor of 20 years and father of six, told The Christian Post. “I just hadn’t seen a tool that could help people.”

The pastor cited research showing that 74% of Gen Z men and 64% of Gen Z women say pornography is a problem for them. A 2024 Barna report, “Beyond the Porn Phenomenon,” produced in partnership with Pure Desire Ministries, found that while practicing Christians viewed pornography less frequently than non-Christians, the difference between the groups was only 14 percentage points.

“Gen Z has been back in the Church in record numbers. That’s amazing,” Klimis, Radiant Mobile's chief operating officer, said.

“But when you also read 74% of Gen Z men say porn is a problem for them, and you see 64% of Gen Z women say porn is a problem for them, then what I’m trying to say is whatever it is we’re doing in the Church isn’t necessarily becoming what I want to champion: a practical solution to a spiritual problem of lust,” he added.

Radiant Mobile launched May 5 and operates on the T-Mobile network. The service costs $30 per month for users already on T-Mobile-compatible plans and includes a network-level firewall designed to block harmful material such as pornography, racism and self-harm content.

According to Klimis, the company emerged in part from his concerns as a father about how to protect his children from accidental exposure to explicit material online.

Paul Fisher, the founder of Radiant Mobile, said the idea for the network also came from his fears as a parent. Fisher said he has a 2-year-old daughter and a 5-year-old son, and he became alarmed by research showing many children encounter pornography accidentally online.

“The idea of in a few years from now my kids could stumble across pornography, that kind of just threw me for a loop,” Fisher told CP.

In addition to the hard-blocked categories, Radiant Mobile allows users and parents to customize restrictions across more than 120 categories, including abortion, pregnancy and sexuality content, according to company leaders.

“We’re putting a practical tool in place for people who want to opt in, for people who want to have a fence around that so it can’t get in, and at least it takes away some of the temptation,” the network’s founder said.

In addition to traditional phone service, Radiant Mobile provides a library of Christian-themed content for children and families. The company offers animated Bible stories, videos about the saints and apostles, and interactive games that reward users for answering questions after watching episodes.

Fisher said the company has obtained rights to use classic fictional characters such as Snow White, Peter Pan and Huckleberry Finn in retellings of Bible stories aimed at children.

After watching episodes, children can answer quiz questions and earn rewards such as additional screen time from parents, while teens can compete for prizes including cash or free phone service, according to the network’s founder.

“We’ve gamified the education process so we can bring people closer to Christ and closer to His Kingdom,” Fisher said.

According to Klimis, while he is aware of other Christian networks, he says Radiant Mobile is “Jesus-centric.”

“When we can start to bring understanding around what the Word of God says, with the stories that God’s given us to tell, that can speak to every practical problem people are addressing in their daily life; the Word of God has an answer for all of these things,” the Radiant Mobile COO said.

“And so, Paul and I have tried to champion telling these stories in a way that’s going to captivate the next generation, bringing the Scriptures to life through the power of animation and AI, and then telling the greatest stories that have just been in the shadows, of saints and apostles that have gone on before us,” he added.

As for demand, Fisher told CP that Radiant Mobile’s waiting list had reached into the “thousands” since the network’s launch May 5. He plans to market Radiant Mobile outside the U.S., noting he has already received inquiries from a telecommunications partner about establishing Radiant Mobile in South Korea.

Although Radiant Mobile has primarily marketed itself to churches and Christian families, Klimis said he hopes the service will also attract non-Christian parents concerned about online safety.

“I’ve given 20 years of my life to serve the Lord Jesus and to take care of the Church at large,” Klimis said. “But safety is my highest core value, and I believe, regardless of what they believe or don’t believe, they should be given that opportunity.”
