A simple guide to eSIM

Whether you’re into the latest tech or just want a hassle-free experience, eSIM could make managing your mobile plan simpler than ever.

So, what is eSIM?

An eSIM (which stands for embedded SIM) is a small chip that’s built directly into your phone or device. Instead of inserting a physical SIM card, your mobile plan can be downloaded straight onto the eSIM.

Think of it like streaming a song instead of popping in a CD, it’s all digital, and it’s all seamless.

What are the benefits of eSIM?

Here’s what makes the switch to eSIM worth considering:

✔ Manage Multiple profiles

Many eSIM-compatible phones support dual SIM, letting you run two numbers (e.g. personal + work) from one device.

Here’s an ultimate guide to dual SIM phones to find out how they work and choosing the perfect one for your needs.

✔ Keep your number, join or stay on SMARTY

Your number can stay exactly the same, it’s just the SIM that changes.

✔ No fiddly SIM swaps

No more worrying about losing or damaging your SIM card, it’s all built into your phone.

Is your device eSIM ready?

Most new phones are. Apple started supporting eSIM in the iPhone XS and newer, and recent Android phones from Samsung, Google, and others are on board too.
