No. PCI DSS Requirement 44.2.2. prohibits the sending of unprotected primary account numbers (PANs) via end-user messaging technologies, whether sent internally or over public networks. E-mail, instant messaging, SMS, and chat are all considered end-user messaging technologies and thus required to meet PCI DSS Requirement 4. 4.2.2. Per PCI DSS Requirement 4,4.2.1, strong cryptography and security protocols must be used when cardholder data is sent over open, public networks.
