No, there is no free SMS API - beware of people offering one! Full answer: This does depend on your country. In over 99% of countries,  No , there is no free SMS API. If there was, spammers would make SMS unusable. USA  has an odd exception to this rule, as most of their mobile companies charge the message recipient. This means they can offer  email-to-SMS gateways , and occasionally a free API. You can use these for free, though the gateways are very unreliable, and mobile users will often block these messages, since spammers use this route. In every country you will see many, many companies who will  appear  to send SMS for free, sometimes with an API. These companies exist to make money, and in most countries SMS costs them money, so they will do at least one of these: intercept your messages and phone numbers, for  resale ,  spam ,  fraud  or  phishing inserting adverts in the SMS or in the interface giving a free sampl...

转自战法： 平常受主管和同事歧视和欺负，准备把他们告到 Prud'hommes, 所以最近和工会的人走的比较近，学会如何 monter un dossier, 和一些保护自己的方法，特别想跟大家分享。 1. Il faut acter 也就是说，如果同事对你有行为或言语上的 Harcèlement, 当下不要过激，但是一定要给主管发一封邮件。 邮件可以保存下来作为证据。 邮件是 Daté 的，可以记录时间日期。 只要邮件是你发的，对方回不回都无所谓，因为你已经公开表示了不满。 如果是言语骚扰，邮件里一定要引用同事骚扰你的原话。 邮件不要有攻击性，你的请求一定是合理的，但是让对方很难回复。比如我主管不批我的RTT，因为他说“RTT不能半天半天的批”，于是工会的哥们帮我起草了一封邮件，就说“我这个月想提交RTT申请的时候，惊讶地发现四月份的申请被拒了。我不明白，全公司的员工都可以请半天的RTT，为什么我不行？而且你已经批了我三月份两个半天RTT的申请。“ 2. Prise d'acte 如果公司没有很好的履行合同，没有支付工资，同事对你有骚扰，甚至是暴力，等等，你就可以立刻终止你的合同。 这个很厉害，不要轻易使用。因为如果法官判定你的请求不合理，就要赔偿公司 Préavis 的钱。 相关链接： http://vosdroits.service-public.fr/F24409.xhtml http://www.journaldunet.com/management/pratique/contrats/4643/la-prise-d-acte.html http://www.juritravail.com/Actualite/prise-acte-rupture-par-salarie/Id/2136  (prise d'acte 和 démission 的区别) 3. 保存邮件 最好是把你所有的邮件都保存在U盘上，备份在自己家的电脑，以免公司突然给你来个 mise à pied, 你就没办法带走任何证据了。但是千万不要大张旗鼓地做，要不然公司就会怀疑你要做什么对公司不好的事。 4. 最有，一些有用链接： http://vosdroits.service-public.fr/particuliers/N19806.xh...
