Ever feel like your phone bill is packed with extra charges for things you don't actually need? AT&T is one of the most expensive wireless providers, but does that mean you're getting better service, or just paying more for the name?
US Mobile gives you access to AT&T's network, without the inflated prices, contracts, or hidden fees. But does it offer everything AT&T does, or are there trade-offs?
US Mobile vs AT&T plans: Do you really need AT&T's premium pricing?
Winner: US Mobile
AT&T's cheapest unlimited plan starts at $75 per month, that's before taxes, fees, and required autopay discounts. If you don't sign up for autopay, your bill jumps even higher.
Meanwhile, US Mobile keeps pricing transparent and flexible. You get the same AT&T network but at a much lower cost, with plans starting at $15 per month. Plus US Mobile is actually powered by all three networks, so you can also choose Verizon or T-Mobile if their coverage is better for you.
