If you want them to be able to see the contact info EVERY time they are working on any opp or service related to the property, use Property Operation Notes. https://care.youraspire.com/en/articles/4763911-using-notes-in-aspire#h_fe33822abb
I’m running into the same issue that the crew/service techs can not see the contact information for the client in the Aspire Mobile app. My current work around is to copy/paste the site contact information to the Operation Notes for the opportunity work ticket so it is visible to the crew.
Operation Notes Workaround for site contact info
Site Contact info not available in Aspire Mobile
@Tim_Nolt , Operation Notes from the Property Home page will show up on Crew Mobile and Aspire Mobile. If they aren’t showing, I’d go ahead and report a bug to AspireCare. See this screenshot from the article I referenced above.

The operation notes appear in the Aspire Mobile app. So no need to report a bug. I confused the Property Notes with the Property Operation Notes. Still would like a better way to get the site contact info to the crew.

Right, property notes won’t show up in crew mobile. Operation notes will. So if you enter in their contact info or a gate code for the property on the Operation Notes on the property home page, that will accomplish what you are wanting.
