Costco is known for its great deals on bulk items. What it’s less known for: cell phone plans.
The warehouse store carries cell phones and plans from the Big 4 carriers — AT&T, Sprint, Verizon and T-Mobile. So you can grab a 2-pound jar of mixed nuts, stock up on organic produce, fill your gas tank and buy a new cell phone, all in one place.
Costco has the same plans you’d find on the carriers’ websites or in their retail stores but offers perks you won’t get elsewhere, such as free accessories or a Costco Cash card. These bonuses may not make it worth a special trip, but if you’re already planning a Costco run, the convenience is hard to pass up.
Keep reading for the best cell phone plans available at Costco. Getting started via Costco’s website isn’t very convenient, so we recommend going to a store. If you prefer to go directly through the carrier, you can do so via the links below.
