I wasn't able to connect successfully but they reported my phone burned through 50 MB and that I owed more than $750. Google maps generally require 1.3 MB per cell. They adamantly refused to reactivate my U.S. data service unless I 'agreed' to purchase an international data roaming package to cover the usage. They eventually reversed the charges but it seems that the company's billing system had bundled my U.S. data usage prior to the border crossing with the one minute of international data roaming.'
