In such a conventional system, when using a mobile phone, the user must go to an agency and make a contract, and furthermore, a seal or an identification card is required. So the procedure was troublesome. In addition, since mobile phones are manufactured with many functions, the manufacturing cost is high, and the user has to bear the price part manufactured at such a high price. The fee for use is at the split price. on the other hand,
When the user no longer needs the mobile phone for some reason, the user often discards the mobile phone in a disposable manner, which wastes resources and is not preferable in promoting recycling. Furthermore, there is a strong demand for compactness and easy portability without being bulky.

In addition to such portable telephones, prepaid cards (so-called telephone cards) have been used. In this case, although the prepaid card can be easily purchased, it cannot be used unless a public telephone is installed nearby, and there is a problem that the use cannot be achieved immediately. Moreover, the used prepaid card is often disposed of in a disposable manner. In this case, too, resources are wasted and this is not preferable in promoting recycling.
