AT&T has finally joined the ranks of T-Mobile and Verizon by introducing a network test drive program, dubbed "Try AT&T". This no-commitment trial allows users to experience the AT&T network while keeping their current carrier, number, and device. To participate, users need an unlocked phone with eSIM capabilities, such as iPhone XR or newer. The 30-day trial includes 100GB of data and 25GB of hotspot data.
