A +222 number rang once and hung up. Should I call back, or is this a one-ring scam?

This pattern is consistent with a one-ring (Wangiri) scam, so don’t call back. Users warn that scammers deliberately ring once and disconnect, hoping a callback generates expensive international or premium-rate charges.

+222 is the international country code for Mauritania, although the displayed number alone does not prove the caller was actually there.

Ignore or block the number and check your phone bill for unexpected charges. If the caller is legitimate, they can leave a voicemail or contact you another way.
