How to Use Dual SIM or eSIM While Travelling
Traveling abroad? Your regular phone plan might end up costing you a lot in roaming fees. A simple way to save money and stay connected is by using Dual SIM or eSIM. This lets you add a local SIM (or digital SIM) for affordable data and calls—while still keeping your main number active.
What is Dual SIM and eSIM?
-
Dual SIM means your phone can use two SIM cards at once – your regular SIM and a second one (either physical or eSIM).
-
eSIM is a digital SIM already built into your phone. Instead of inserting a physical SIM card, you just download a plan.
Using Dual SIM or eSIM is super helpful when you’re travelling:
-
You can keep your home number active for calls and texts.
-
Use a local SIM/eSIM for cheap data and local calls.
