Can China Unicom Ice Cream Package be used across provinces?

Of course. The ice cream package is not divided into the province and the outside, and the voice and traffic are common throughout the country. However, if there is a master card and a slave card, the master card and the slave card can enjoy free local common language interaction and call transfer, and at the same time, the slave card and the slave card can also enjoy free local common voice interaction and call transfer. As long as one of the master card or slave card is not local, it is an ordinary call and does not enjoy free calls with each other.
