Unicom card SMS has been closed. Can I go to the place where I can buy cards?

1. SMS function is usually turned on by default, and no application is required. If you need to reopen after closing, you can contact the local manual customer service or business hall to understand the opening situation.

2. Secondly, after the SMS function is enabled, you need to set the correct SMS center number to use the SMS function normally, because the SMS center numbers in different cities are not consistent. It is recommended to consult local manual customer service or business hall, which is subject to local policies.
