You get 5GB of high-speed 4G\/LTE data every single day. Once you use that up, your speed drops to about 1 Mbps, but you can still use data as much as you want—no hard cutoff. Think of it as \"unlimited basic data\" after your high-speed quota.

We've had thousands of customers use this plan, and very few run out of high-speed data before the daily reset. Unless you're streaming Netflix in 4K for hours every day or constantly downloading large files, 5GB handles maps, social media, video calls, music, and browsing with room to spare.
