Like people aren't going to take advantage of that. And why should they not? If J carriers are stupid enough to do it. There have been cases of people contracting repeatedly 5 TalkingSIMs and then canceling within days. While JCI claims that they are not in financial danger from this, they believe it is an unsound business practice and are in official opposition. The MIC has said that there is nothing to be done but wait for the J carriers to pull their heads out of their collectives α$$ε$.
「事業者の自主的な対応策を待つしかない」Now, JCI has added a ¥10,500 cancellation fee to TalkingSIMs that are used for less than 1 year. Softbank has also added a cancellation fee to their prepaid SIMs (¥9,975).
And it isn't just customers that make out well:
Actually JCI makes a big profit because they pay and don't use our network. We object because it is not right.It may be getting more difficult to sell off the phones to second hand stores, as I imagine supply/demand pendulum has swung over to glut.
