Hello @asthajoshi and welcome to Telia Yhteisö -forum. I hope you find interesting discussions and answers here.

Is the problem been for a long time or have suddenly started? As first i suggest you to reboot phone and toggle the airplany/fly mode on for a while and then switch back to online. This makes phone to reconnect mobile network as “fresh” connection. Does these help anything?
