Why Battle.net (Blizzard) Restricts Virtual & VoIP Phone Numbers
Blizzard Entertainment enforces 'SMS Protect' for free-to-play competitive titles like Call of Duty: Warzone and Overwatch 2. Blizzard employs strict carrier lookups that reject not only VoIP numbers but even some prepaid virtual lines with: 'Please enter a postpaid phone number'. USAVerify Pro provides genuine physical SIM connections from AT&T, Verizon, and T-Mobile that pass Blizzard's stringent carrier verification.
