Does short message notarization charge by number or by article?

This belongs to evidence preservation. The party who needs a mobile phone goes to the notary office in person with his mobile phone. You can get one in three days. Of course it can be expedited. Personally, I think it's about 500 yuan. The number of companies is 1000. Specifically, it still depends on the amount of notarization content. Ordinary SMS 500 is enough. Every copy 10 yuan. This is charged by the piece.
