Im going to China at the end of Feb. for work. I was wondering if anyone here can give me some tips on how to get my photon working over there? Do I wait till I'm there and buy a sim card? Only going to be there for 7 to 10 days but it would be nice to have my phone working. Thanks for any advice. This will be the first time I have been out of the country with my photon and I would love to take advantage of my first "world phone".
