My Internet quit working all of a sudden while I was abroad. Why?

Most recently modified:

In order to protect our customers, we automatically block all data connections abroad when charges exceed CHF 300 per month. We will send you notification of the costs when the amount reaches CHF 50, CHF 100, and CHF 200. You can unblock your account for another CHF 300 at any time simply by sending an SMS to the number 3310 with the text UNBLOCK.
