Do you need the ATT or T-Mobile data plan active to receive Over The Air (OTA) updates of does this just provide a hot spot in your SUV? Secondly do you need a data plan or service plan for the MBUX system to work? What happens when your warranty runs out, do you loose a lot of functionality from the MBUX system?

OTA updates do not require a data plan. Most of your services run for 3 years. You can check the list and their expiration dates on the web portal.
