No signal indoors

[JoSa]

I suddenly lost a signal inside my house. I cannot make or receive any calls. O2 gives a different information about the signal issues in my area (GU10 4NN), one that there isn't any and another that there is an issue with the mast. The latter one has been on a website for at least ten days now, so I do not think is true. My phone works outside my house. Indoors, it does not even list O2 as an available network. It lists Vodafone and EE, and my foreign SIM cards connect to these with no problem.  It might be a silly question, but I recently replaced windows in my house. They are thicker than the old ones, but nothing exceptional or bulletproof! Could it be a reason for the loss of signal? And if it is, what can I do about it, apart from switching to Vodafone or EE?

Use wifi calling when indoors.

Have you @JoSa tried standing outside of your house - on the driveway, in the back garden etc - to establish whether or not you can then get a signal ? Or even standing inside the house with the window open ?

 My phone works outside my house.

Yes, the phone seems to be working on my drive. Also, works, although badly, in the room where window has not been changed.

Thanks @JoSa, it was not clear whether you had tried it immediately outside of home or some distance away. 

I wonder whether @japitts might have a view on this ? 👍

AI Overview

Yes, windows can affect mobile signal: 

• Glass

  Glass is good at reflecting and scattering radio signals. The more panes of glass in a window, the more interference there is. Double- or triple-glazed windows can block signals more than single-glazed windows. Modern windows with low-emission (Low-E) coatings deflect even more signal. 
• Other materials

  Other materials that can affect mobile signal include:

  • Metal: Metal can cause the most damage to call reception, with up to 50dB loss when getting through a metal barrier. 
  • Wood: Plywood can cause losses of between -6dB and -9dB. 
  • Stone, brick, and tiles: Can cause up to roughly -28dB of loss. 

To improve your mobile reception, you can try opening a window or using a repeater. A repeater works best when there is a good outdoor signal that can be boosted indoors.

Thanks, but is there a better solution than opening a window? I cannot keep my windows open, especially in winter, just in case someone might ring me!

Also, why is my wi-fi calling not working? It says check the network. Is this connected to my windows? I have no issue connecting to the internet via wi-fi in my house.

[JoSa]

Wi-fi calls do not work either. I get the message "check your network". Otherwise, I have no issues with connecting to wi-fi at home.
