[Leica] OT: Sim Chip in Europe

[Brian Reid]

Mobile phones have radios in them, and those radios use certain 
frequencies. It is not guaranteed that a phone configured for T-Mobile 
use in the USA will be able to communicate with European cell towers. If 
it can't talk to the cell tower, then the SIM won't matter. I shopped 
carefully to find a 4-band phone to maximize the chances that my phone 
would work in other countries.

I recommend that he get comfortable with using WiFi, which is available 
in many public places in the countries you have named.
