Has anyone tried using one of the TIM smart phone plans on a Mifi to tether several devices?
Could save money if you don't have big data needs but wonder if they can detect you're connecting several devices:

My 119.it account shows the SIM being tied to my Mifi device (Huawei E585). Not sure if that was registered by the shops where I bought the SIM or recharged it or they detected it from the IMEI.
