When you can purchase International Roaming, you essentially purchase data packs in chunks of 0.5GB. Voice and SMS are charged separately on pay-as-you-go rates.
You can check the data as well as SMS and Voice rates for each country from our app or website.
To avoid bill shock, we highly recommend that you use data (or Wifi if that’s available) instead of voice or SMS whenever possible. Check out our blog to know how to save on International Roaming charges.
