Problem description
Following paths must be verbs per design guideline:
/connectivity
/roaming

From Design Guideline:

When the POST method is used, the resource in the path must be a verb (e.g. retrieve-location and not location) to differentiate from an actual resource creation.

Expected behavior
"/connectivity" may be changed to "/retrieve-connectivity-status"
and
"/roaming" may be changed to "/retrieve-roaming-status"
