The Only SIM You Need When You’re Traveling Overseas

SIM for intl travel

An electronic SIM (embedded SIM) or eSIM is a rewritable SIM card built into a cellular phone, like a smartphone or a smartwatch. With an eSIM, you no longer need to pop open a slot to put a SIM card in compared with a physical SIM. Moreover, it never leaves your phone, and you can simply download a digital SIM from your chosen provider. This makes electronic SIM handy while traveling overseas.

That means instead of having a little circuit board that pops out of your phone, you only need to deal with software. Once eSIM rolls out in the international market, people will benefit from its incredible advantages, such as the ability to switch carriers, hold multiple carriers on your phone, and let you stay updated in multiple countries.

The Benefits of an eSIM

You can see the real benefit of an eSIM when you move to or visit a new country. You might want to still use your foreign number once you’re in a foreign country. But if you want to save money and avoid expensive international roaming charges, get a cheap local number and use it instead while you’re in a foreign country.

For those who have moved and now have a different life, you’ll probably be up against many difficulties as you learn to adapt to your new environment. Still, you might need your home-country number for multiple reasons, such as receiving confirmation texts from a bank or government institute. An eSIM helps you avoid the need to switch between SIM cards every time.

Other than confirmation texts from banks, you might also need your home-country number for travel benefits. You can simply put your new-country number on your phone with an eSIM. If you decide to go someplace else for a holiday vacation, then you can buy a local SIM.
