When traveling, you can easily add communication plans for your destination

When traveling abroad, you can avoid paying expensive roaming fees by using an eSIM from a local (country) carrier. By using local communication plans at tourist or business destinations, you can enjoy data and calls at reasonable prices. Also, if you plan to stay in multiple regions, you can save money by switching to the appropriate eSIM for each region you need.


Dual SIM allows you to switch communication services to suit your lifestyle
