I purchased Prepaid 15GB simcard in Prague and it was good for the month, the month ends, then I want to buy this deal again but the only option I can see is to buy another new sim card? Well now I am outside of the Czech republic so how is it possible? The store assistant assured me I could keep using this sim and number abroad all across europe but I see now way within this vodafone web interface to make that happen. The only option to buy the red 20gb plan the button to buy it is greyed out and anyway it appears to be for buying a new sim and not just the data package. I just want to keep using the sim card and have the data again! Why is it so hard?? Thank you,
