I will be spending three weeks in Sterzing-Vipiteno in July, flying into Munich then riding by bus to Sterzing-Vipiteno. I have an unlocked smartphone and would like to get a SIM card with prepaid service for data (internet) and calls to the the U.S. and any local numbers I may need to reach.

First of all, will I have any problems with Italian phone/data service being so close to the border, or even traveling into Austria? Should I look for a SIM card in Munich? Would the service work in Northern Italy?

Sterzing-Vipiteno doesn't appear to be a very large city, and I don't see any Wind or Votafone sellers there. Is there a way to get a SIM card by mail in advance (this doesn't seem to be a practical option)? Or it is likely that I will be able to find what I need in Sterzing-Vipiteno? All suggestions welcome. Grazie
