Should You Use eSIM?
eSIM, short for Embedded SIM, is an electronic SIM that can replace a traditional physical SIM card and supports functions such as calling, texting, and storing plan information. This type of SIM is extremely small and is soldered directly onto the device’s motherboard during manufacturing. eSIMs are also suitable for small devices that lack space for a physical SIM, such as smartwatches.
With its outstanding advantages, eSIM is increasingly chosen by customers and has become a new technology trend:
-
Users can easily switch carriers or plans without visiting a physical store or using a SIM ejector tool. Everything is managed conveniently through online software.
-
eSIM supports integrating multiple phone numbers on a single eSIM, allowing users to flexibly use different numbers for personal or work purposes.
-
eSIM reduces the risk of someone removing your SIM if your phone is lost, since it is embedded in the motherboard and cannot be taken out.
-
Especially when traveling abroad, registering for an eSIM helps you avoid removing and swapping SIM cards, which can lead to loss or damage.

Should You Use eSIM as Your Primary or Secondary SIM?
To answer the question "Should you use eSIM as your primary or secondary SIM?", you should consider the following points:
If you use eSIM as your primary SIM, you can use it for all activities on your device such as making calls, sending messages, registering for plans, and using data. However, your device must support eSIM, and each time you change devices, you will need to set up the eSIM again. If you rarely change phones or chase new technology, eSIM is very suitable to use as your main SIM. Using eSIM as your primary number also helps you avoid issues like SIM card damage.
If you want to use multiple phone numbers by scanning eSIM QR codes on the same phone, eSIM can also serve as a secondary SIM. Therefore, whether you choose eSIM as your primary or secondary SIM to ensure continuous connectivity depends on your individual needs.

Using eSIM When Traveling
Instead of searching for and purchasing a traditional physical travel SIM, you can choose an international eSIM plan with the simple step of scanning a QR code and activating the plan. This allows you to use the eSIM as a secondary SIM for internet connectivity while traveling abroad.
Travelers prefer using eSIMs because they can keep their devices connected wherever they go without the hassle of swapping physical SIM cards or worrying about huge roaming bills when they return home.

The Benefits of Using eSIM as a Primary or Secondary SIM for International Travel
Choosing whether to use eSIM as your primary or secondary SIM for international travel depends on your personal habits and connectivity needs. For many travelers, using eSIM as a secondary SIM dedicated to data while abroad offers maximum flexibility and convenience, allowing you to keep your main number active while enjoying seamless internet access in any country.
