When travelling abroad, staying connected can be expensive if you rely on your home network’s roaming charges. Many travellers now choose eSIMs as a cheaper and more flexible alternative. In this guide, we compare eSIM vs roaming costs and explain which option is best for your trip.
What is roaming?
Roaming allows your phone to connect to a foreign mobile network using your home provider. While convenient, roaming charges can be significantly higher than local data plans, especially for international travel.
What is an eSIM?
An eSIM is a digital SIM card that lets you download a mobile data plan directly to your device. Instead of paying your home provider for roaming, you can connect to a local network using a prepaid eSIM plan, which is often much cheaper.
