Can I upgrade or downgrade the service tier? If yes, how does that affect my billing?
Yes, it’s possible to change the SKU in the managed tier using the Azure CLI. Users will be charged at the price for the previous SKU up until the point of change, and at the new SKU price after the change is made.

Standard networking fees apply to network egress from or between Azure data centres. We recommend maintaining a registry in the same data centre as your container deployments. See the geo-replication preview feature to manage multiple regions as one, providing network-close deployments across multiple regions.
The bill will display the cost of each managed registry based on the SKU of the registry, as well as any network charges.
Basic, Standard and Premium tiers include an amount of storage as part of their pricing. As storage exceeds the included amount, registries are charged for their additional storage.
