We have all gotten them at some point or another, the ominous text message from an obscurely long phone number cautioning us that we have either used all our allotted monthly data on our phones, or we are dangerously close.

But, as more mobile companies roll out unlimited data plans, Verizon Communications (VZ) - Get Report is the latest to join the party. The company will begin, on Monday, selling an unlimited data plan for the first time since 2011.

"I think people are going to be skeptical of this," TheStreet's Jim Cramer said on CNBC's "Squawk on the Street" Monday morning. "Not only does Verizon need more bandwidth, but also their plans are still above Sprint (S) - Get Report and T-Mobile." (TMUS) - Get Report

Cramer noted that outspoken and always lively T-Mobile CEO John Legere will point to this move as one born out of desperation by Verizon, when T-Mobile reports earnings on Friday.

"The main thing we need to remember is that this is completely defensive," Cramer contended about Verizon's unlimited plan.

Furthermore, Cramer believes that both T-Mobile and Sprint have waged a battle against Verizon, arguing that both companies attest that Verizon doesn't offer anything substantially better than the two.

"This has really struck a chord with millennials who seem to have some kind of aversion to Verizon," Cramer stated. "This will be a very interesting fight, I don't know how much Verizon gets out of it."
