I had my phone nicked in a fast food outlet in a mall , put it down on the counter for 1 second to pick up the food bags , a very respectable well dressed girl standing behind me distracted me and job done , didnt even realise for a few seconds but they dissapeared quicker than I could know what was happening . Lucky I had two days to go and managed until I got home but it was a pain , take a cheap phone and maybe a spare just in case . I found a tesco £10 mobile was able to use foreign sim cards ( not tried one in Philippines) without being unlocked but dont know if they have tightened up on this ?
