We are located in the mountains, when you arrive to our cabin you have limited or no network connectivity, depending on service provider. We send a welcome package on how to access the cabin and also provide the WiFi name and password. Today we had a group arrive and they could not get into the cabin. They could not access the Airbnb messages since they had no network connection. Customer had to drive offsite to get a network connection to access the Airbnb app to get the door code. We do have a note stating there is limited network connectivity. Not sure what else to do to help prevent this from happening again.
Hi! You should call them well in advance or send them SMSs or messages on WhatsApp/Viber and make sure they read them well in advance before they arrive. Inform them about the problem
In confirmed reservations, you have the option to attach a JPeg inside the Airbnb messaging system. I send arrival details in a Jpeg, which guests can download to their phone in case there's no network.
You can do the same and just make it very clear that they have to download before going to the cabin.
