Can i use a second super-compact 4G WiFi as a booster in my home?

[500miles]

I have mobile broadband with a super-compact 4G WiFi thing (this one https://ee.co.uk/broadband/pay-monthly-mobile-broadband-gallery/4g-wifi-details)

For (long, boring) reasons, I have ended up with two of them. Can I use the second one as a booster? The signal currently doesn't reach to the other end of the house -  old property, thick walls so if I can it would be perfect...

Hey there @500miles!
Welcome to the EE Community 😊

It's not possible to utilise the second device you have directly as a booster, they would be viewed as independent devices.

Whilst it would be possible to get a second SIM to pop in your other device and have this in a different part of the house, they would have separate WiFi networks so you could notice them competing.

Ok, That’s what I suspected! 
thanks for confirming @Peter_W
