What are the advantages and disadvantages of SMS?

1. It can effectively transmit text information, and reading text is more conducive to seeing clearly than speaking. If you directly tell the appointment place through SMS, you won't make mistakes or find your way;

For example, if you go home to have dinner together, in a simple word, it is not cost-effective to make a phone call. Especially in the case of long distance, roaming, etc., SMS is also the first choice.
