Activating sim cards
Yesterday I bought two sim cards, each with £10 prepaid for Vodafone. One was fitted to a same-day purchased Doro 'dumb' phone and the other to my Nexus 6 'smart' phone.. Attempting to use either produces a "You have no credit" message and the call is terminated. Attempting to contact Vodafone and/or Sainsburys is pointless since both have 'robori' only contact services.
Any gurus who might have useful pointers, please ?
