In this guide, we explain how dual SIM works, how to use an eSIM alongside your regular SIM, and what you need to know before setting it up.
What is dual SIM?
Dual SIM allows your phone to use two mobile plans at the same time. This can be a combination of one physical SIM and one eSIM, or in some cases two eSIM profiles.
This setup is especially useful for travellers who want to keep their main number active while using a separate data plan.
Can you use eSIM and a physical SIM together?
Yes, most modern smartphones support using an eSIM and a physical SIM at the same time. This allows you to use one line for calls and messages and another for mobile data.
For example, you can keep your home SIM active for calls while using an eSIM for cheaper data abroad.
How to use dual SIM while travelling
Using dual SIM while travelling is straightforward:
- Keep your primary SIM active for calls and messages
- Install your travel eSIM for mobile data
- Set your eSIM as the default for mobile data
- Turn off roaming on your primary SIM to avoid extra charges
This setup allows you to stay connected without high roaming costs.
Which phones support dual SIM with eSIM?
Most modern smartphones support dual SIM functionality, including:
- iPhone XS and newer
- Google Pixel 3 and newer
- Samsung Galaxy S20 and newer
However, features may vary depending on the model and region, so it’s worth checking your device settings.
Are there any limitations?
While dual SIM is very useful, there are a few limitations:
- Some phones only allow one data connection at a time
- Switching between SIMs may require changing settings
- Not all carriers support all features
Despite this, dual SIM remains one of the best ways to manage connectivity while travelling.
