my secondary phone

i must have a switzerland number, because i'll work there a lot of time next year, so i bought this cheap low end phone with orange prepaid card for a price of the card. i know this is not the newest and best machine but it's enough for receiving calls and messaging. am i right or not? i hate changing two or more cards in one phone. now i found an solution. cheap crap which i like more than my goodlooking but extremly slow siemens.
