Hello. 3 days ago I bought a Smart Zero prepaid card and I've been using data like a nerd but no charges have been applied this far. Unfortunately for me, noone in the store spoke english and I don't know how to switch the voice menu in english. May someone please tell me how much does it cost and when charges will apply? I hope one day soon I won't try to open Maps only to find out that my credit ballance is € -150
Thank you very much.
