Testing OTP feature- Need dummy international phone numbers

I am testing a feature in which an OTP/Text message should be received on the phone number I enter in the api request.

I would like to test it with different phone numbers- preferably Scandinavian countries.

From where I can get dummy phone numbers, where I can check the received message as well.

I found one site: http://ift.tt/2hJqbbQ (my message shows delivered but i cant see it in the list here)

Also If someone can share use cases/test cases/test scenarios that I can test, would be highly appreciated and helpful.

Regards
