- I don't have a phone, how can I play for free?
- I cannot play the game for free, it asks me to add a phone number
- I cannot add my phone number to this account, I already added it to another account
Call of Duty: Modern Warfare II, Overwatch 2, newly created Call of Duty: Modern Warfare accounts, require that you add a phone number to your Battle.net account.
In addition to the games mentioned above, some games require a phone number in order to use the in-game features like World of Warcraft Group Finder or unlocking the World of Warcraft 4 extra bag slots (requires both a phone number and Authenticator).
Limiting the number of free accounts that a single person can create helps keep players accountable for their actions and, in turn, reduces toxicity and cheating and ensures a positive community experience for all players.
If you already registered your phone number to play for free —or you own a paid copy of the game— this error means that you are logging in with the wrong email. Log out, make sure you enter the correct Battle.net email, and log in again.
