Does it matter if China Mobile shuts down the international SMS function WeChat?

Closing the international SMS service only means not receiving or sending SMS messages outside Chinese mainland, which has no effect on the WeChat function. To turn off the international short message service, you need to call the service staff in your business hall and ask them to help you turn off the international short message service, or you can turn it off yourself in the service hall. You may have to pay a certain termination fee before you can close the SMS service, or you can only close it when the SMS service contract is terminated.
