If you're moving to another country, you’ll need to change your Google Play currency.
Remember, however, that you can only do so once per year.
The Google Play Store automatically changes to the new country once you set it, but it can take up to 48 hours to apply the change.
How to Change Currency in Google Play 
1. Open the Google Play Store app.
2. Tap on your profile icon (Menu icon) in the top-right section > Settings.
3. Choose General > Account and device preferences.
4. Go to the Country and Profiles section, then choose your new country. This option only appears when in a different country than your current profile’s setting.
5. Select "Save".
