目前,市面上出售的各种电话密码锁、长话限制器,虽然电路复杂、价格不菲,但效果却并不理想,人们只要略施小技,锁零电话就不能真正锁零。本人在实践中摸索出一种最简单但却最“彻底”盼限拨方法,现提供给有兴趣者参考。 At present, all kinds of telephone password locks and long-distance telephone switches on the market are sold. Although the circuits are complicated and costly, the effect is not satisfactory. People can not really lock up their phones only if they use a few tips. In practice, I worked out one of the most simple but most “thorough” hope dialing method is now available to interested parties for reference.
