Can China Unicom Mobile be used abroad?

Domestic China Unicom and China Mobile users can use it abroad, but they need to activate international roaming services in advance, and the cost of using them abroad is higher.

China Unicom and China Mobile do not have signal coverage abroad. To use it abroad, you need to use the network of a local operator that cooperates with domestic operators. It is a high-priced rental, so the cost is high.

If you use it abroad for a long time, it is recommended to apply for a local mobile phone card.
