I received the Mexican version of this product and the instructions were only in Spanish. The access data did not work either. However, after looking at the English manual online I was able to do a factory reset, after that the credentials worked and I was able to log into the web interface, although I had to change the language from Spanish to English. With that said, my device was unlocked and while it wasn't easy to set up, it looks like it's working.
