please switch to cellular data

Go to -> Settings -> Mobile network -> Mobile data -> Turn it On.

Mobile data options -> Data roaming -> Turn it On.


To connect to Internet you need Wi-Fi or Cellular Data (a subscription or a prepaid with data).

If one is not available, the other is used to establish a connection.
