How to Play ‘Overwatch 2’ Without a Phone Number

“Any Overwatch player with a connected Battle.net account, which includes all players who have played since June 9, 2021, will not have to provide a phone number to play,” the developers wrote in a blog post detailing changes to the game following its launch.
