U.S. carrier Verizon abolished unlimited data plans a while back, however customers still holding onto an unlimited plan with the network have reportedly been able to upgrade to Apple’s iPhone 5s or iPhone 5c while maintaining their account’s “Unlimited Email & Web for Smartphones” status.

The news comes from 9to5Mac, which explains the situation: “Contrary to Verizon’s stated claims that it is ridding itself of unlimited data plans on iPhone upgrades, a few readers have been able to upgrade to the iPhone 5s or 5c and keep their unlimited data,” the website notes.

It’s not presently known if this is a glitch or some new Verizon regulation, however.

One such plan.

Given that 4G LTE access is now available in countless locations across the United States, unlimited data is undoubtedly more useful than ever before. Such would make it possible for users to enjoy music streaming, video consumption, and FaceTime over cellular outside of a Wi-Fi network, limit-free.

So far, nothing has been confirmed by Verizon, and as such we can’t recommend that subscribers go headlong into an iPhone upgrade believing that their unlimited data will be preserved. We’ll keep you updated with further information on the situation as we receive it.
