How to send a short message to Unicom with a Canadian mobile phone?

Unicom mobile phone users send short messages abroad in the following ways:

1. Method of sending SMS to domestic number: directly input the other party's number.

2. Method of sending short messages to international, Taiwan, Hong Kong and Macao numbers: 00 recipient country code+mobile phone number or+recipient country code+mobile phone number.

Add 0 1 1 before the country code. Therefore, the domestic number is 0 1 186, which is the same as international direct dialing, with 0 1 1 added. Note: Don't send Chinese, what China received is garbled. Only English can be sent. If you send a Canadian number, it can be displayed in Chinese (if both parties are China mobile phones), but once you cross the border, you can only use English. Every country has a code for sending text messages, and this code is in the SMS settings. You need to add the corresponding country. It seems that our country started on August 6th, and other countries can send it according to the number set by the mobile phone, saying that it has the best mobile phone port code.
