Another reason a foreign mobile phone might work better is 1) A foreign phone can connect to any of the 3 networks: O2/Virgin, Vodafone/Three and EE/BT. It can automatically choose the one with the best signal. 2) Your UK phone can only connect to a specific one of them depending on your phone contract. So, in summary, there are many different aspects that affect voice quality. -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug
