The vacationer used a total of 9.5 GB of data in Europe. T-Mobile, which said it was "sorry," offered the unfortunate consumer a credit to repay his debt.

The company, cited by local media Scripps News Tampa, recommends that its customers always "check the travel features of their plan, such as international data roaming, before leaving." If the plan doesn't include it, they'll need to "ensure they're using airplane mode or wi-fi when sharing data to be sure their device isn't connecting to an international network, the company said in a statement. The man hired a lawyer to have the bill canceled, and the bill was later reduced to less than half the amount he had been charged for the trip. He assures the New York Post that he warned his operator, T-mobile, before his trip.
