For the UI:

We can use this service from AWS to implement the feature: https://aws.amazon.com/vi/sns/

@chungquantin I'd suggest using Firebase Authentication instead of Amazon SNS for the following reasons:

Sending messages is free for Firebase
Amazon SNS is more suitable for mass SMS distribution. For our app, user is required to verify their phone number only once during account registration.

Because we have a push notification service on our mobile app which is implemented using Amazon SNS. So I think using Amazon SNS for this service will reduce much effort in implementation.

Because install a whole Firebase SDK just for the use of SMS sending may not be a good idea. But if you don't want to implement the Amazon SNS, you can try Firebase! 😋

@chungquantin You're right about the light implementation with Amazon SNS. However, non-US phone numbers will be charged for multi-factor authentication SMS. How should we go about this in order to test if the feature works properly?

Hmmm, I think it is more complicated than I thought. I found out there's a service https://sms.to/gateway/vietnam that support sending sms to vietnam local phone number in a fast way. Maybe we can try it.
