I see at
http://www.prepaidgsm.net/en/italia/tim.php that a refill can be any amount and that the SIM card expires 12 months after the last refill. Does this mean that one can refill by only €0.01 in order to prolong expiry by another 12 months? Does each refill method have a different minimum amount?
Does the ID card or passport used to buy the SIM card dictate the name on the account forever? Or is it a bit like South African RICA where these details are just logged in a database and never referred to again? For example, if someone else buys a SIM card for me, can I subsequently put my own name on the account?
Is it easy to get a nano-SIM?
