The question Is there any 3g data package that works across Europe? was closed as a duplicate of Choices for prepaid GSM data with laptop tethering in Europe?. I originally agreed with this, but there are a number of differences between the questions.
- Many carriers are openly hostile to tethering and threaten to charge full rates (several dollars per MB) if you are caught or to cut off your service.
- Tethering restricts the question to plans with large data caps
I suppose an argument could be made that it should be closed as a "shopping" question, but in this case it would apply to both questions.
