Some Wi-Fi networks ask you to accept terms or sign in on a web page before you can use them. This is common in hotels, airports, and some schools and yeshivas.
The Kosher Qin Phone has no web browser, so it can’t open these sign-in pages. That means these networks usually can’t be used on the phone.
What you can do instead
Use mobile data if your plan includes it.
Use a Wi-Fi network that only needs a password (like most home networks).
