Does anyone know how to set a windows 10 laptop with a sim card in it that if the internet (Wi-Fi) fails, it automatically switches to the internet from the sim card? So that you have no internet for just a few seconds?
By that I mean if the Wi-Fi is still there and only the Internet itself fails that it then jumps to the Internet from the sim card
If your laptop does not have a SIM connection, you need a UMTS stick. There you can insert your SIM card and surf.
PS. Depending on the laptop, it can always take a while. E.g. For me 20 seconds.
Are you sure you mean a laptop and not a tablet?
Windows actually does this automatically, i.e. Both networks are active and cable / wireless will always be preferred when everything is on. That's how I know it from my Win10 desktop.
