I had a very bad experience in Italy 2013 after three weeks in Macedonia., when the Samsung phone (cell) the roaming turn ON and I was not aware until I came back to Toronto. Thanks god I did resolve the problem as I was charging big $$ money. From what I am reading I should not take it with me? What usually people from Europe or North America using when traveling in Japan. I was also told you can even replaced the syn-card let's say the canadian with a japanese one? is this true! Coming back from Tokyo to Paris I was told I can buy the local syncard . I intent to remove the syn-card when I leave Canada. Any suggestions? much appreciated.
