Metrico Wireless tested iPhone 4S network performance for Verizon, AT&T and Sprint.
(WIRED) — The iPhone 4S is available on three major carriers, leaving potential buyers to wonder whether AT&T, Verizon or Sprint is the better network choice.
Pricing plans aside, carrier quality is a significant factor in anyone’s purchasing decision, and now consumers have hard data to help them choose: A just-released study reports AT&T is tops for fast data speeds, while Verizon is the most reliable when it comes to making phone calls.
Sprint’s main draw is that it offers unlimited, albeit slow, data.
