Is the area code used to send text messages between cities on mobile phones?

No matter whether you use a mobile phone or PHS, the other party is a mobile phone and does not need an area code. If you add it, it will be wrong. If the other party is PHS, you must add the area code. There is no need to add 106, it has become history. If the other party is a landline, it is useless to add anything.

If you charge, SMS will be a dime from 2009, regardless of operators, other areas and roaming.
