Problem Description
The CAMARA version of the current DeviceStatus API lacks a crucial "ageOfInformation" or "last_updated_timestamp" field, resulting in inconsistent behavior across vendors. This absence poses challenges for application developers in determining the freshness of roaming status data.

Expected Behavior
Propose the addition of a "last_updated_timestamp" or similar field in the API response to indicate when the roaming status information was last updated.

roaming: true
countryCode: 262
countryName: ["DE"]
last_updated_timestamp: “2018-04-05T17:31:00Z"

Alternative Solution
Explore and discuss any alternative approaches or fields that could address the issue. Consider other methods or data points that might serve the same purpose, assessing their feasibility and effectiveness.
