New Premium Unlimited Plan Delivers Unmatched Mobile Experience at a Better Price

Mobile

Meet Xfinity Mobile’s newly introduced Premium Unlimited plan. Xfinity Mobile now offers two tiers of unlimited data plans—Unlimited and the new Premium Unlimited, which delivers gigabit speeds and adds new features that enhance performance and deliver more value.  

A Premium Mobile Experience 

Cost savings is a common motivator for people who switch mobile phone carriers, but that often comes at the expense of performance. Xfinity Mobile’s Premium Unlimited plan ensures that customers don’t have to sacrifice performance for savings.  

Customers who subscribe to the new Premium Unlimited plan get the following enhanced features included:  

WiFi PowerBoost 

More than 90 percent of Xfinity Mobile data traffic happens on WiFi, and now mobile customers have access to WiFi PowerBoost, delivering gig speeds over WiFi in and out of the home. 

By combining America’s fastest broadband network—with more than 23 million WiFi hotspots—and the most reliable 5G network, Xfinity Mobile delivers the fastest mobile speeds in Comcast markets1. The latest Speedtest Intelligence®research from Ookla shows that customers’ average speeds on Xfinity Mobile have increased a remarkable 150 percent since the launch of WiFi PowerBoost. 

Elite Upgrade 

New with the Premium Unlimited plan is Elite Upgrade, a perk that offers phone upgrades twice a year, with a guaranteed new device discount up to $830 with an eligible trade-in device.  

4K UHD Streaming 

Included with Premium Unlimited is 4K UHD video, the highest resolution available for mobile. Customers get clearer and sharper video when streaming on the go.  

More Hotspot Data 

Take your own personal hotspot wherever you go. Premium Unlimited customers get 30 GB of 5G hotspot data—ideal for laptops, tablets, and other device—with speeds reduced after 30 GB.  

Spam Call Blocking 

With Xfinity Call Guard, customers will have the confidence to answer their calls knowing advanced filters are blocking spam calls before they even reach their phone. 

Cut Your Bill in Half 

Customers with two Premium Unlimited lines will cut their bill in half during the first year compared to similar plans from the big three cellular companies.2 Curious about how much you can save if you switch to Xfinity Mobile?
