Is the SMS charge deducted from the phone bill?

Yes, generally speaking, you are not in the dynamic zone, and there is no special SMS package. You just deducted it from your phone bill.

If it's a dynamic zone with a monthly SMS package, it's free as long as it doesn't exceed the number set by the package ... If it exceeds the number of SMS customized by the package, then the SMS in the network is a dime, and the SMS out of the network (Unicom and PHS) is a dime, which is deducted from the phone bill. ...

If it's a non-dynamic area, it's usually a dime inside the network and a dime outside the network, which will be deducted from the phone bill ... But there are also SMS packages similar to Shenzhouxing, about 2 yuan 100 (depending on the specific business situation in each place) ... After sending the number of SMS packages, the phone bill will still be deducted according to the standards inside and outside the network, only more specifically.
