How to send short messages from China Unicom to China Mobile in Australia?

Hello, Unicom's mobile phone roaming abroad is the same as texting at home. Just send it directly to the mobile phone number.

As for whether the receiver roams, it should not be the scope you should consider when sending text messages.

Just like you don't need to consider whether domestic users are roaming in other provinces before you make a phone call or send a text message.

Of course, the premise to ensure the success of sending and receiving SMS is that both parties have opened international roaming, the phone bill is sufficient, the number of SMS center is set correctly, and a universal mobile phone card is built in. The standard frequency of the mobile phone is correct and the signal reception is good.

For other details, please call Unicom customer service or overseas Unicom international roaming service hotline for consultation. (I can't send the number, search online)

Take pictures with your mobile phone. If it helps, please adopt it. If in doubt, please ask.
