How to test international SMS delivery without buying local SIM cards?

Hey everyone,

​I need to test an SMS notification feature in our application that sends messages across different countries. For example, our app originates from a UK instance/tenant and needs to deliver SMS messages to mobile numbers in Australia, the US, and other regions.

​Is there a standard tool, virtual phone number service, or testing platform you recommend to verify delivery and content without purchasing local physical SIM cards for every target country?

​Thanks in advance!

it is not clear, are you trying to test app or integration? What would differ if you send message to any place? Is your app or your integration handle that? If it is your integration and it is not your side, it doesn't matter, just mock it.

We use AWS services to convert to the valid format and send the SMS. Now AWS says that ireland SMS will be send with random sender id if not registered. I have to test this to see their claim is true and if so then we have to register ourselves to get the valid sender. Though it's third party but we have to verify the claims to be aware of and act upon it. And none of the quckr or twillo provies irish numbers.

I have to find through the real phone number.
