手机保证书200字篇一

为了维护学校正常的教育教学秩序，保证学生在校学习、生活的和谐与安全，养成良好的生活行为习惯，构建“绿色”校园文化，促进身心健康成长，我们同意学校决定：禁止学生带手机等移动通讯进校园。

特此保证如下：

1、我们一定严格遵守学校不携带手机、小灵通、mp3等移动通讯工具进入校园的规定。

2、协助学校宣传禁止学生在校园内使用手机等移动通讯工具的积极意义，促使自己在思想上与学校规定达成统一，在行动上自觉地不在校园里使用手机等移动通讯工具。

3、保证在校学生学习、生活的和谐和安全，减少外界的干扰。

4、严格遵守学校不携带手机、小灵通等移动通讯工具进入校园的规定。从即日起，如有违反，自愿接受学校相应的处理（处理方式是将手机当面砸毁）。

致此

敬礼！

手机保证书200字篇二

尊敬的xx：

这是一次十分深刻的保证书，我对于我这次犯的错误感到很惭愧，我不应该违背老师的话，我不该上课玩手机，带手机到学校来。恳请老师可以原谅我的错误，我这次的悔过真的很深刻。

不过，人总是会犯错误的，当然我知道也不能以此作为借口，我们还是要尽量的避免这样的错误发生，希望老师可以相信我的悔过之心。我的不良行为不是向老师的纪律进行挑战。绝对是失误，老师说的话很正确，就是想要犯错误也不应该再您的面前犯错误，我感到真的是很惭愧。

我真的已经很深刻的认识到了我的错误，知道了老师说的话不能够装做没有听见，老师说的话就要听从，老师说过话也绝对会实现她的诺言，老师所要管的一定是为了我们学生好，在此，我保证！今后绝不再犯类似错误，如有再犯，严惩不待！！

致此

敬礼！
