Carriers have extended the grace period to help enterprises and SMS aggregators register all A2P Long Code SMS messaging traffic and moved to sanctioned 10DLC routes.


Starting March 1st, AT&T increased the passthrough fee on non-registered traffic. Heavy filtering will also be implemented by the major carriers on grey routes (routes used for the delivery of unauthorized international A2P traffic).


As a reminder, please note Shared Short Codes that are not controlled by a single message sender/content will be at risk of termination.
