Is the SMS charge deducted from the phone bill?

When users buy a package containing the number of short messages, sending short messages will be deducted from the number of short messages in the package first. When the number of short messages in the package is used up, the excess will be deducted from the user's phone bill balance according to a certain fee for each short message. Some special SMS services, such as international SMS and SMS group sending, will need to pay extra fees, which will also be deducted from the user's phone bill balance. Telephone charges refer to the pre-stored telephone call charges, that is, the fees paid in advance by users for using telephone services. When users make calls, send text messages or use other telephone-related services, they will deduct the corresponding fees from the telephone bill balance according to a certain proportion. When the balance of telephone charges is insufficient, the telephone service will be suspended until the user recharges or pays the charges again.
