How much does Unicom charge for sending text messages?

Different packages have different tariffs and policies. If you use Unicom's 4G national package, you will be charged 0.20 yuan /MB when the usage traffic exceeds, and 1MB will be charged for the part where the cumulative online traffic in the current month is insufficient. If you want to know the details of foreign investment costs of other packages, I suggest you contact your home customer service.
