I am asking this question in behalf of a teacher from my school and was wondering if anyone
could help me

Next year the school is heading over to switzerland for three weeks on a trip and instead of going on global roaming and getting a large bill as the boys use their
phones for a wide range of services (data,calling and texting) we were thinking of purchasing swisscom simcards when arriving and using them for the three weeks

My question is that if the boys take their XT handsets with them should the phones work on the swisscom network for text and calls (don't really need to bother about data)? I know that some of the boys have the R100 handsets, an iPhone and the nokia handsets that telec
stock but I was just wondering if someone could
give me an idea if they should work.

Thanks
Tane
