Flutter:在无需用户在Android上进行交互的情况下发送批量短信的更好方法 [英] Flutter: Better approach for sending bulk SMS without user interaction on Android

问题描述

在我们的项目中，我们需要将批量SMS发送到我们的整个客户列表(列表中大约有200个用户)，以获取每月的会费.

In our project, we need to send bulk SMS to our entire customer list (around 200 users in the list), for their monthly dues.

我们将:

1. 向所有用户发送第一条短信

1. send first sms to all users

第二条短信给待付款用户

second sms to pending payment users

向剩余用户发送第三条消息

final third message to remaining users

我们不能将SMS Gateway与API一起使用，因为在使用该应用程序的地区互联网不可靠，因此我们希望将SIM卡用于SMS.

We can't use SMS Gateway with API, because the internet is not reliable in the area where this app will be used so we wanted to use SIM for the SMS.

问题:

1. 如何在没有用户交互的情况下发送短信?
2. 我们如何提示您选择SIM卡? (双SIM卡手机)
3. 将Future与async一起使用是否是发送大容量SMS的好方法，还是有其他替代方法?

1. How can we send SMS without user interaction?
2. How we can prompt for SIM selection? (dual sim mobile)
3. Does using Future with async is good approach for sending BULK SMS OR is there any alternative available?
