Thank you. However since
AT&T have dropped their unlimited data plan there are only two very expenisve medianet options left (1MB for $4.99 and 5 MB for $9.99), so AT&T GoPhone is a no-go for data.
Also international calling (e.g. Germany for $ 1.49-1.66/min) is a real rip-off. Don't you have any discount-MVNO over there?
