You no longer need to subscribe to one of AT & T’s latest plans to get a proper 5G sample. The operator is adding 5G and “5G +” (its nickname for millimeter wave 5G) to some of its legacy unlimited plans, including simply titled Unlimited, as well as more advanced levels like Unlimited & More Premium. Ordinary users are expected to see 5G starting in March, while business customers with older plans will receive 5G data starting in April.
You will need a 5G compatible phone (real 5G, not 5G Evolution) and you will receive an email or text message when 5G arrives at your plan.
Legacy support is part of a broader 5G strategy for 2021. AT&T expects to have 5G millimeter waves in 17 sports facilities by the end of 2021 and expects to start developing its C-band wireless spectrum around the same time. In other words, it is shifting from implementing basic coverage to increasing average speeds and filling in gaps.
Legacy support is a break from the early days of 5G, when operators (including Verizon, controller of Engadget) wanted to charge more for 5G and direct customers to newer and probably more expensive plans. It is unlikely to be an altruistic movement, of course. You may be less inclined to switch providers if you know you can achieve higher 5G speeds and less lag with your existing service. It might be worth it for AT&T to sacrifice a little extra subscriber revenue if it means retaining more customers in the long run.
