I verwnde 3 of these cards and everything works perfectly.

I use 3 of these cards. One I bought a long time and at 3, 2 recently on Amazon. As a phone card every month as long as credit is being debited until everything consumed. Then you can no longer call active, but take calls is up to one year after the last charging possible Registered as data card runs the balance 1 month, or if the amount of data is consumed before, one month will be charged again. If not surfed and one month is over will not be charged !!!! As can be surfed and phoned 3 like home in Italy to Austria cost that is ideal for me. Of course you can also surf with 3G. I would buy if necessary the Card at any time.
