The verdict, & two little voices

Should you actually get the NUU A23?

Our takeEditorial
The NUU A23 at $39 new is a genuine entry-level option for shoppers whose budget is truly limited. It handles the basics — calls, texts, essential apps — and its no-contract availability through Gen Mobile keeps the total ownership cost as low as possible. Storage at 16 GB is genuinely tight in 2024 and will require active management, so any buyer should confirm microSD support before purchasing. For its intended use case as an affordable everyday communicator or backup device, it's hard to argue with the price. Set realistic expectations for what hardware at this tier delivers, and the NUU A23 fulfills a real and underserved market need.

The Optimist
“Thirty-nine dollars. That's the price of the NUU A23 — brand new, no contract. In an era where flagship phones cost over $1,000 and even mid-range devices regularly exceed $300, the existence of a $39 smartphone is nothing short of remarkable. For a child's first device, a temporary replacement phone, or a dedicated hotspot workaround, the value here is undeniable. NUU Mobile has been quietly building devices for the budget prepaid market for years, and they understand their audience: people who need to get connected, stay connected, and not spend a fortune doing it. Every American deserves smartphone access, and the NUU A23 makes that possible at a price point almost anyone can manage. Paired with a Gen Mobile plan, your total monthly phone cost could be among the lowest imaginable.”

The Cynic
“The NUU A23 has 16 GB of storage — in 2024. Android itself consumes a significant chunk of that, leaving precious little room for apps, photos, or anything else. The NUU brand carries limited recognition and minimal after-sale support infrastructure. At $39, you're buying hardware that was economical to produce, and every component reflects that reality: the screen, the processor, the camera, the battery. This is a device that will feel frustratingly slow within months, will run out of storage constantly, and will likely be replaced within a year. The math of spending $39 now versus $80 on something meaningfully better doesn't always favor the cheapest option when total satisfaction is considered. Buy it if $39 is truly your limit — but know exactly what you're getting.”
