yes, telecom network consists of two critical component, one is radio access network and other is core network, the core is already cloud native i.e the 3gpp specification itself is written for microservice architecture while the radio access network software's run on k8s but they are still big monoliths, I would say already 40% of 5G is running on k8s, few like dish even runs on vmware on aws.
