No Wi-Fi roaming in London

[LondonGuest]

Yesterday I offered to take an American friend on a walk around London via WhatsApp video. It totally failed. 

No Wi-Fi was the message. But I could call her. So audio was working. Why didn't video work? It is a brand new physical UK SIM card from EE. Very disappointed.

@LondonGuest  In the settings of WhatsApp, have you got it all allowed to use Wi-Fi and cellular ?    From your description, you’ve got it set to use only Wi-Fi that’s why you got a “ no Wi-Fi message”. It’s an app setting not a network issue

Thanks! You're right. Hope that makes the difference. I'll try it today!  I really appreciate this, Chris. It was very exasperating. 🙂
