Hi @nigeljohn88 👋,
Thank you so much for your reply, I am so sorry that the signal is so bad you are hanging out of a window, this is not what we would like to hear and hope it was safe, I can see you mentioned this has happened when you came back, do you know if any settings were changed your end? Did you receive a new sim at all? Does the WiFi calling work fine when connected to WiFi? Is this all areas or just at home you are noticing the drop in service?
Please keep us posted on this.
Zoie
