Does it mean that the balance will not be deducted during the mobile upgrade? If there is an exercise during the upgrade, will the money be deducted afterwards?

Don't believe rumors ~ it is impossible to start a business without deducting money!

During the upgrade period, due to the impact of the billing system, the balance will not be deducted, and the phone bill will not be deducted temporarily. After the upgrade is completed, all the expenses you incurred will definitely be deducted ~

When drilling for the first time, there is no charge within 72 hours, and the charge will start after 72 hours. It will be opened after 2 1 in the current month, and there will be no charge in the current month, and the next month will be charged 1, with one-time deduction.

This is self-deception. If you fill your mailbox with short messages, you won't receive the message. . .
