Just to clarify my earlier comment, you should be able to subscribe to premium if you're in the following countries with payment details that match the country: United States, Germany, United Kingdom, Canada, Singapore, Malaysia, New Zealand, France, Belgium, Austria, Spain, Italy, Switzerland, Netherlands, and Ireland.

For users outside these countries, we know that it's not as clear in the experience that premium isn't available yet, and we'll be making updates very shortly to make this more clear. Additionally, we'll continue to try and grow the list of countries that Relay is available in, so please give us your feedback to help us prioritize expansion. Also, the free experience is available globally, if you're not able to subscribe to Premium yet, but still want to use Relay.
