I'll look at it. Also, is it possible to set up a hotspot on a phone that doesn't have a local network connection? I want my app to share data between phones on a desert island, mountain top etc. No internet connection. I tried this on a phone without a service provider and got a connection error that said it couldn't connect to "Verizon's server". Verizon was the old provider at some point in the past.
Neither of my Verizon phones would allow hotspot even with mobile data disabled. It did work on other non-Verizon phones.I've just tested it on a device without sim card and hotspot works.
Try to disable mobile data and see whether it helps.
My guess is that your device is locked to Verizon and they put a limit on this feature.
I'm not sure if this is relevant.Neither of my Verizon phones would allow hotspot even with mobile data disabled. It did work on other non-Verizon phones.
