Not the next-gen network speeds we were promised

ATT 5G Phones

Carriers in the US may have launched their commercial 5G networks in 2019, but the next-generation technology is still in its infancy. Coverage is spotty, supporting phones are still few and far between, and so far the high-speed gear in the hands of consumers has failed to meet the hype. Unfortunately, that includes AT&T 5G.

With numerous sports modes, an advertised two-week battery life, built-in GPS, heart rate monitoring, and more, you would think you’re getting a great bargain for the price. In fact, when I reported about its launch in India, I thought the Amazfit

Samsung Galaxy Watch 3 review: small changes to a known formula


Five years since the first Apple Watch and a full seven years on from Samsung’s Galaxy Gear, we know what a smartwatch is. We know that it’s not going to replace your smartphone anytime soon, that it will need to be charged every day or two, and that its best functions are for fitness tracking and seeing notifications when your phone isn’t in your hand.
