My Verizon service averages about 15 - 18 Mbps-the AT&T service was 3-6 Mbps and I dropped a call twice
That's a pretty crazy drop in speed. Fortunately, where I live Verizon and AT&T coverage and data speeds are very similar. AT&T even beats out Verizon data speeds at my families vacation spot on the Oregon coast. It was a pretty easy decision for my wife to make when AT&T announced their new shared data value plans.
