@Kulsum2 Unfortunately your Wifi situation may end up making it impossible for you to use Airbnb. Not responding to Requests or Inquiries penalizes you on Response rate, and if you go too low on that rating, Airbnb will suspend your listing. We live in a digital age and Airbnb is an online platform.
I do wish they wouldn't have such an image-heavy site that takes so long to load if you don't have high-speed reliable Internet (I have iffy internet sometimes, too). I don't see any reason why if we just want to access our hosting pages, that we have to go through waiting for the main page with all its photos to load- we don't need to see that.
You can wish all you want that Airbnb would use Whatsapp or Facebook, like you could wish for someone to give you a million dollars, but that's not likely to happen 🙂
All the best.
