I have plan visit the Asian country as Vietnam, Thailand, Singapore. I want to know my phone can receive the call and text massage from Canada.
Incoming text messages are always free with Fizz. However there is no voice coverage with your mobile phone number while you are in Asia.
You can purchase a data travel add-on for the Asia region to allow you to access the internet when you don't have access to Wi-Fi. To know more about your travel options, you can consult this Fizz FAQ - https://fizz.ca/en/faq/im-travelling-outside-my-coverage-zone-what-are-my-roaming-options
If you have any further questions, you can ask users here in the community forum or if needed, you can contact Fizz customer service directly by chat - https://fizz.ca/en/support
