Can I receive a text message sent to Angola?

I don’t know whether your friend is using a domestic card, whether he has activated international roaming, and whether he is a China Unicom or China Mobile card. If it is mobile, call 10086 to ask whether Angola can provide international roaming services and whether your friend has activated it. If it's from China Unicom, just call 10010 and ask. If the country can provide international roaming services and your friend's mobile phone card has activated this function, you should be able to receive the text message
