I would check your postcode via Vodafone uk-coverage-map and zoom out on the map to check surrounding masts too. 


As a process of elimination can you insert your SIM card in another phone to see if the SIM has developed a fault. 


A Samsung Service Centre or Samsung Experience Store will be able to help you further with this situation via a diagnostic on the phone too.
