Will an Asus Transformer Prime bought in the U.S. work in Portugal? I live in Portugal and I'm going on vacation to the U.S. in a few months.
I'd like to buy an Asus Transformer (Prime or 300) while in the U.S., but I don't know if the Wi-Fi or 3G will work in Portugal.  I only know for a fact that 4G doesn't work.

Can anyone help me on this one?
The tablets in Asus Transformer line (including TF 101, Prime TF 201, and Pad 300) do not have a cellular modem, so they will only work on WiFi.  WiFi is a universal standard and will work just fine in any country, provided that your router supports the 802.11 b/g/n specification.
