I haven't tried yet i was planning on going to Spain,Amerstdam and Italy within the year
I haven't tried yet bro. Have you read your manual i have not read the manual yet i am guessing it will have some info. Call Boost to see what they have to say i know that they do not offer service outside the USA except for some places like Australia if i am not mistaken. Remember Boost Mobile is Sprint and Sprint only has CDMA USA COVERAGE. Pretty much everywhere in the WORLD IS GSM ONLY There are a few Asian Countries that are CDMA. I am pretty sure that all you need to do is Purchase a SIM CARD WITH SERVICE for the Part of the World you will be in. Then Insert the CARD AND RESTART THE PHONE I THINK THAT IS HOW IT WORKS.
LET ME KNOW IF YOU FIND OUT ANYTHING BRO.
