Something are supported :

from Czech Republic: T-mobile, o2 -> supported

from Portugal: MEO, NOS -> supported

from the UK: Three, o2 -> supported

from Estonia: all operators -> NOT supported

from Sweden: Telenor, Telia -> NOT supported

and internationally for instance from China: all three major operators: China Telecom, Unicom and Mobile -> supported

For see exact surcharge % for Czech and Portugal, I need exact number ( operator code after country code ?) for operator. May be some numbers can be found in internet.
