I cannot receive 2-factor authentication verification messages through Text

Issue

TyrellCorp Text does not receive verification messages for 2-factor authentication (2FA) or multi-factor authentication (MFA). 

Resolution

By default, long code numbers cannot receive messages from short code numbers.

Avoid setting up a verification code to be sent to your TyrellCorp number. Since multiple agents would then have access to the security code, this could allow for a security breach. To resolve this issue, set up authentication messages to be sent to an individual agent's phone.
