Verizon Wireless’ new unlimited data plan threatens to destroy everything, fear Wall Street analysts in an open panic attack over the prospects of value destruction and network reliability damage.

“An unlimited offer is dangerous,” Roger Entner, an analyst at Recon Analytics LLC, told Bloomberg News. “If they sign up a lot of people, it will congest the network, and they run the risk of people saying ‘the network sucks’.”

The return of unlimited data at Verizon (with a protective right to throttle customer speeds after they consume 22GB of data during the month) seems to have triggered anxiety on Wall Street because Verizon was the most adamant about never offering unlimited plans again after dropping them in July, 2011. Part of that fear may have come from Verizon’s own former chief financial officer Fran Shammo who warned investors last fall:

“The majority of people don’t need unlimited plans. But the people who use unlimited plans can be abusive, they can really wreak havoc to your network. And at the end of the day, I continue to say you cannot make money in an unlimited video world. You just can’t do it because you need to generate the cash flow to keep up with your demand.”

What also concerns Wall Street is the increasing evidence an all-out price war provoked by T-Mobile and Sprint will threaten to close some doors on network monetization. Charging customers for data consumption has a growth prospect that would have guaranteed increasing average revenue per customer indefinitely. But unlimited plans mean consumers pay one flat price for data no matter how much they consume. Consumers love it. Wall Street analysts generally don’t.

Other analysts are concerned that Verizon, deemed the Cadillac Network because of its premium price and reputation, also happens to have the least amount of deployed wireless spectrum of all the four national carriers. As the nation’s largest carrier with 114 million users, a big spike in data consumption could affect Verizon’s network performance, some speculate.

Unlimited data plans promote usage and total wireless traffic is expected to grow between 70-80% annually, up from 50-60% under today’s tiered data plans, according to wireless analyst Chetan Sharma.

In response Verizon has rushed out executives to reassure Wall Street and investors Verizon’s network was built to take it.

“Our goal is to always offer a better performance, and I see a path to that,” Mike Haberman, Verizon’s vice president of network support, said in an interview with Bloomberg:

“Spectrum is only one element of a network,” he added. “How you put the network together is far more important.” In advance of its decision to start selling an unlimited data package, Verizon was busy with upgrades. The company just boosted network capacity by 50 percent with new systems that take separate radio frequencies and combine them into one large pathway, Haberman said. The company has also been adding more cell sites and transmitters in cities and connecting those sites with high-capacity fiber-optic lines.

CNBC reported Verizon’s new unlimited data plan is a “sign of weakness” for Verizon, which is facing challenges to its core wireless business. (4:30)
