Over the last year, the term “eSIM” has become a part of our lexicon. But not everyone knows exactly what an eSIM is. It is not an electronic SIM card, as some of us think. eSIM is an embedded SIM card inside of your smartphone. Actually built into it. Or any other device that supports this technology. It is easy to activate an eSIM. You just scan the QR code, which is generated and then sent to you by your carrier.
It should become easier to travel with the arrival of eSIM technology. You won't have to use international roaming on your home carrier anymore. Which has some financial, traffic volume, and speed issues associated with it. You'll also free yourself from an aggravating search for rate plans at local carriers--in an unknown country. Now you can arrange everything prior to your trip. Search and select rate plans on the website of the carrier or that country where you plan to go. After you pay online, you get a QR code and go on your trip with an activated eSIM for travel.
