Question re Vodafone Smart Passport and Square Smart
 

I'm coming back to Italy, and, still ignoring Effendi's good advice and keeping my Vodafone SIM (arriving on a Saturday night, don't want to try to find a WIND SIM on a Sunday, and I still have money left on the SIM from my last trip.

I see I can activate Vodafone Square Smart, which gives me 1 GB of internet and 500 SMS.

I see that there is Smart Passport for €3 per day, which appears to allow me to use my 1GB monthly allowance in the specified countries.

Or I can pay €2.50 per day and receive 50 MB per day.

Am I understanding this correctly?
