Can anyone here translate English -> Italian

[Effendi]

Yes, it fine.
You can also print a message like this, to show to the clerk:

Buongiorno, vorrei attivare una nuova sim Wind prepagata con piano tariffario Super Senza Scatto. Assieme alla sim vorrei attivare subito l'opzione Call Your Country e fare una ricarica di 10 euro. Grazie.

In English it is:

Good morning, I'd like to activate a new prepaid Wind sim card with the Super Senza Scatto tariff plan (I think it's the best one). Together with the sim card I'd like to activate at once the Call Your Country option and recharge the sim card with 10 euros

Anyway I think a dealer in the very centre of Rome, where it's full of tourists, should be able to speak some English...
