My Recommendation:
US Mobile's Unlimited Dark Star plans all offer exceptional value on AT&T's network. This plan is no exception. I give it a solid recommendation as long as you are ok with paying for your plan a year in advance and no better monthly plan deals are running. Be aware that if you like to perform lots of speed tests or try to use this plan to replace your home internet, US Mobile may slow or suspend your service.
How This Information Is Verified: Pricing and features on this page are sourced directly from the carrier and monitored for changes. Because wireless plans can change at any time, readers are encouraged to report discrepancies so updates can be made quickly.
Note: As of February 2026, I’m going through every provider plan indexed on this website and updating them. It is expected to take weeks to complete. Until then, some plans will have some info that is either missing or out of date.
