Welcome to Vodafone Community
I appreciate how frustrating it is when signal fails, fringe coverage or intermittent connection presents issues.
Is signal Ok when you leave your home area ?
Your area is shown as a patchy area for 3G and 4G.
Please check if you've not already done so what the Vodafone Network Mast Status Checker is reporting for your area.
Your Local masts may show as OK so Please also use the Zoom out feature in the map to check surrounding masts for issues.
Vodafone have provided a specific Self Help Thread that holds Initial Checks and a Template that asks certain questions that will Help us and the Tech Team to ascertain what's possibly going wrong in your area. Please would you re post the template with your answers.
