Campaign FAQs

  • Why only currently serving military? What about veterans?

Our currently serving military are those most likely to be deployed or separated from their families. Also, the verification system we have chosen to use works best with active email addresses. We know Caribu would be great for all members of the military community as well which is why we’ve kept the monthly subscription fee at an affordable price so they can also use Caribu with their families.

  • How long is the free subscription?

Your Caribu subscription will be free throughout your active duty status. You will need to renew each year to verify active status.

  • Does the other caller have to subscribe as well?

Only one account has to have a subscription. This account can invite family members to download the Caribu App and enjoy video-calls with the subcriber for free.  To invite family members, tap on the green “Call” button and then tap on the “Add New Contact” icon.
