When travelling overseas, making local calls and having plenty of data are essential to help you navigate and enjoy your holidays.
The answer is to purchase a local eSim in the country you are travelling through.
Modern phones make it easy to use eSims for data and calls. Simply sign up for the eSim before you travel.
Then activate it as your preferred data carrier when you land in the country, and away you go. There will be plenty of local data and calls to make life easier.
