At present, there is no such technology, so we can only transfer mobile phone calls to fixed lines, and it is impossible to transfer fixed lines to mobile phones or PHS! !

Of course, PHS can use 20 1 card, or it can stop. ..

The only other way is for you to carry your dormitory phone with you ... haha.

Anyway, it won't work! ! ! !

Why is it called a landline? Think about it. ...
