Mobile phones can't send text messages abroad! Ask for an answer!

I consulted the customer service representative for you. The situation is as follows: At present, China Mobile cannot support China mobile users to send short messages in Cuba, but it can receive them for free. In other words, it is just a single service. It has nothing to do with your mobile phone settings.

But I asked the customer service representative of the mobile company in detail at noon. She told me that there was no need to change the center number, mainly the sending format. International code (00)+ country code+mobile phone number (such as sending it back to China: 0086+ mobile phone number), but later she called me back to correct what I said before, and I was told that China mobile users can only receive short messages in Cuba, but not send them. If in doubt, please ask your relatives and friends to reconfirm for you.
