Re: What do you expect?
Such contracts have been repeatedly ruled illegal in Europe.
Citation please? I am in Europe, and my cellphone data plan is quite clear, 100GB/month at full 4G speeds, potentially reduced speed beyond that. Nothing illegal or unreasonable about it.
Fair use clauses over here are such that if a customer's usage is extraordinary the company is _olbliged_ to contact the customer before doing anything at all to their connection.
No, the company is obliged to contact the user when they are heading for an unexpectedly large bill. If the contract says your data rate is capped after a certain point, then that is perfectly legal.
