 Um, the only thing I can think of is they may have, uh, this type of communication blocked at a network level and they may not know it. Like they're whoever their provider is may just block that sort of traffic because, uh, I don't know, maybe it's insecure. Maybe it's just not what they want on their traffic. Why do you need the wifi callings? Your, does your phone not work well in the, in the area?
