Abstract
A system and method of regulating attachment between a cellular wireless device and a wireless carrier system includes: attaching a vehicle telematics unit to a cellular base station using a long-term evolution (LTE) cellular protocol; detecting that the vehicle telematics unit is able to carry out voice communications but unable to send short message service (SMS) messages using the attached cellular base station; ending cellular communications between the vehicle telematics unit and the selected base station in response; and beginning cellular communications with a different cellular base station that permits circuit-switched SMS messaging.
