Use data connections smartly – 3 principles

Domestic communications networks have endured the increased traffic well, but the networks can also become congested in some areas momentarily. Here are some tips from telecommunication company Telia (External link) (In Finnish), with the help of which each of us can affect the volume of data communications.

1. Use a fixed network

It is worth using services that consume a lot of data, for example game and video streaming services, on Wi-Fi.

2. Favour talking and using sound when teleworking

Do not use video connections unnecessarily, because, compared with talking, video consumes a lot of data.

3. Phone someone close to you

If the data connection becomes tangled at times, press the green button on the phone and make a phone call. In a mobile network, talking always takes priority over data. In exceptional circumstances, an easy and concrete act that helps others is to phone someone close to you and tell that person that you care.
