Sorry, if this thread has been discussed somewhere already, but I couldnt find the revelevant thread.

I will be arriving to Beijing next month and I was planning to use UBER for my hops around town. Unfortunately both on my cell and tablet, when I input (while still being here in Europe) any location in Beijing the UBER app crashes with an unauthorized message popping up....

Is this only because I am located in Europe, but trying to input a Chinese address (thus will work once I am physically in china?) or does it mean I need to get a Chinese SIM at the airport once I arrive or is it caused by something else?
I have a an European UBER account with a European Mastercard linked to it.

Many Thanks for the advice
