Travelers have traditionally struggled to stay connected when overseas. Sure, they can get a physical sim card when they land, but that just opens a new can of worms for them to deal with; a very possibly expensive

There is one solution, though. eSIMs!  eSIMs have been around for a while, but they’re now getting the recognition they deserve for being the path to easier travel life.

Have you ever wondered how an eSIM operates? Here’s all you need to know about this amazing technology that makes traveling easier and keeps you connected while on the road.

Introducing eSIMs

To use mobile data and cell service, every phone requires a SIM card. Users manually place this tiny piece of hardware into a phone tray that goes into their phone. You probably know the drill. When you’re constantly switching from phones or SIM card to SIM card, it gets annoying.

An eSIM, on the other hand, is a chip fused directly into the circuit board of a phone. Along with the classic SIM tray, many newer devices now feature eSIMs as an alternative for convenience.

The advantages of having an eSIM?

  • You are not confined to just one data plan with eSIMs like you are with the traditional sim card. Freely transfer between networks without having to disable accounts permanently. This function is handy when traveling since it allows you to stay connected to a network no matter where you are. It’s also generally a more cost-effective option than turning on global roaming.
  • No longer carry several SIM cards with you every time you travel. No more will you deal with the hassle of inserting another chip into your device or even losing them along the way. Even better, an eSIM eliminates the frustration of trying to find an earring or paper clip that fits into the tray’s hole in order to open it.

How Does an eSIM Work?

Now we know what eSIMs are, let’s see how they work!

An eSIM is basically a physical SIM card gone digital so it works the same as your physical SIM card. You just make sure you are carrying an eSIM-compatible phone. You most likely are, as most new models are manufactured to be.

When you buy a data plan from Simly, you can install the eSIM directly on your device. It only takes a few moments, and you’ll get the amount of mobile data you need for the length of time you’ve purchased.

It is important to note that an eSIM data plan is completely separate from your regular carrier. You don’t need to worry about expensive international data chargers and you can keep using your phone number since you don’t have to remove your SIM card from your phone. 

Done. The best part is that you can renew your data plan seamlessly without having to visit the store and on the spot as soon as you arrive at your new destination.

You might have the option to use an eSIM from your existing operator. But in most cases, you’d need to contact your carrier or in some cases go to a physical store, so plan for this time in advance if that’s the path you’re taking.

That’s what you need to know about eSIMs and how they work!

You will never lose it because it is connected to your phone’s circuit. You’ll also be able to acquire local data plans practically wherever you travel for less money.
