@ColinSm_3409738 Probably best not to use it because it will be extremely expensive - please see p20 of the Smarty Price Guide.
If you have a reasonably modern phone, you could try a Travel Esim - there are a number of companies out there offering them. They offer data to use while in the country and so you make calls via WhatsApp (or similar app). From experience with Roamless, you can also make a voice cll via the app, but this is not the cheapest method unless you really need to call a phone not via data)
