DerekPerkins said:The NissanConnect Services and NissanConnect EV & Services telematics programs will be affected by AT&T's decision to discontinue its 3G cellular network. On February 22, 2022, all Nissan vehicles equipped with telematics hardware compatible for use with the 3G cellular network will be unable to access NissanConnect Services and NissanConnect EV features. New enrollments for these vehicles will also no longer be allowed after June 1, 2021. After this point, customers who are not already enrolled in a telematics trial or subscription will be unable to access services for their vehicle. The decision to discontinue 3G network coverage was not made by Nissan and this change is not within Nissan's control.
Maybe AT&T is causing connectivity issues as they're moving away from 3G?
They are not dropping 3G support until Feb’22. My Tesla is going in for the LTE modem upgrade soon to avoid the rush in the coming months.
