Adverse weather conditions and storms can sometimes cause a power outage to your home.
If there is a power cut and the internet stops working, the phone service and devices dependant on the broadband connection will not work either.
If the broadband network itself has not lost power, then you could use a battery back-up. This can enable you to temporarily power your router and modem, in the event of a power outage, to remain connected to the internet.
If you have a VoIP (Voice over Internet Protocol) landline, this is a technology that allows us to make calls over an internet connection, the battery back up will also allow you to make and receive calls.
There are currently battery backup devices available on the market that you can purchase, or your service provider can advise you.
