Huawei, OnePlus and a handful of other manufacturers have already promised to release a 5G-ready phone in the first half of 2019, but Apple is planning to launch its 5G-capable iPhones in 2020. Given that Apple and Qualcomm are locked in a bitter battle, Intel would be supplying 5G radio chips to the company, which might begin testing it out next year. However, the proliferation of 5G-enabled devices in the market will not necessarily translate into a high adoption rate, at least according to AT&T CFO.

Even though most major carriers have already started rolling out 5G, AT&T says that the adoption of the new standard would take considerable time. While speaking at Morgan Stanley TMT Conference conference in Barcelona, AT&T’s CFO John Stephens said that while the long-term revenue prospects look good, it will take years before 5G-ready devices outnumber 4G and 3G devices.
