问HN：有没有其他人觉得在新应用中使用短信变得不可能？
我正在尝试原型一个应用程序，使用短信作为邀请其他用户参加活动的渠道（类似于Partiful的体验）。到目前为止，这个过程的体验如下：
- 我注册了Twilio并获得了一个本地号码。
- 我构建了我的Twilio集成，在测试中发现我的消息被阻止，直到我提交一个“10 DLC”合规的活动。
- 我支付了15美元提交了一个10 DLC合规的活动。
- 两周后，我的活动被拒绝，我不得不重新提交并再支付15美元。
- 一周后，我的活动“获得批准”，我可以开始发送短信。
- 短信开始发送，但有些消息被过滤，并出现模糊的“您的消息内容被标记为违反运营商指南”的错误。
- 我联系了支持团队，几天后他们建议我对消息进行一些修改以符合运营商的指南。
- 我进行了修改，但仍然收到相同的错误。
- 现在我有点无计可施。原型代码已经完成大约四周，我希望能有一些用户来测试。我可以退而求其次使用电子邮件，但由于这个应用主要面向移动用户，短信将是最佳体验。我没有预料到在测试时发送短信会遇到如此多的障碍。
还有其他人有类似的经历吗？有没有我忽略的替代方案？还是说这就是目前的状况？

I'm trying to prototype an app that uses SMS as a channel for inviting other users to events (similar experience to Partiful). This is what the experience has looked like so far:<p>I signed up for Twilio and got a local number<p>I build my Twilio integration and in testing I find that my messages are getting blocked until I submit a campaign for "10 DLC" compliance<p>I paid $15 to submit a campaign for 10 DLC compliance<p>Two weeks later my campaign was rejected and I had to resubmit and pay another $15<p>One week later my campaign was "approved" and I could start sending SMS<p>Messages start working, but some of them are getting filtered with a vague "Your message content was flagged as going against carrier guidelines" error<p>I reach out to support and a few days later they suggest some changes to my messages to comply with carrier guidelines<p>I make the changes and I'm still getting the same error<p>And now I'm kind of dead in the water. The prototype has been code-complete for about 4 weeks now and I'd love to get some users in to test it. I could fall back to email but since this is going to be targeted largely at mobile users SMS would be the best experience. I just didn't anticipate this level of friction to even just send SMS to myself to test.<p>Is anyone else having this experience? Are there any alternatives out there that I'm overlooking? Or is this just the state of things now?
