Following are the reasons due to which we should use mobile phones rather than landlines during the storm.

1. The cables used in landline connection are the good conductors of electricity, hence the charge may flow through it and we may get an electric shock.

2. The mobile phones send signals through the air which prevents the charges to flow through our body.

3. Also during a thunderstorm the telephones lines may get destroyed due to which there will be an interruption in communicating with the person.
