Google cloud platform Twilio抛出错误作为无法到达的目标手机

我们正在使用twilio发送消息，但由于TwilioText消息集成正在关闭，我们使用cloud run部署了该集成，具体步骤如下： 在部署消息成功发送之后，现在突然在twilio中出现错误

有些消息发送成功，有些消息出现错误。有人能帮我一下吗？提前谢谢你，因为可能会有一些无法到达目的地的原因

1.The destination handset you are trying to reach is switched off or otherwise unavailable.
2.The device you are trying to reach does not have sufficient signal
3.The device cannot receive SMS (for example, the phone number belongs to a landline)
4.There is an issue with the mobile carrier

The first step to troubleshooting this issue is to attempt to replicate the problems. 
Attempt to send another test message to this user via a REST API request, or through the API Explorer in the Twilio Console.
