True - it won't work in every situation. We're planning to communicate similarly to how Airbnb communicates when a host gets a booking - push notification, text message, and email at all once. In the cases where someone doesn't have data, they often are still able to receive texts (not always).

Either way, we already over-communicate to the client to make sure they know what to do. Eventually, the agent's app will be helpful too, so the agent can recognize the client if the client uploads their photo to our system.

Your idea about Wi-Fi is certainly something to explore as well.
